Talk: Use of an Animal Model to Study Post-traumatic Elbow Contracture

Abstract: Post-traumatic joint contracture (PTJC) is a debilitating condition wherein increased stiffness following injury leads to motion loss and disability. The elbow joint is particularly susceptible to PTJC and suffers from a lack of adequate treatment options. The progression of elbow contracture is unpredictable and poorly understood, making it difficult to devise prevention strategies. Our lab developed an animal model to study PTJC of the elbow using injury and immobilization to induce contracture in rats. Our animals demonstrate significantly impaired joint motion and biological disruptions similar to the human condition. Importantly, these changes persist following remobilization of the joint, demonstrating the induction of long-term joint dysfunction following instigation of clinically relevant soft tissue injuries. Our work represents the first animal model capable of investigating injury specific to the elbow, a complex yet highly understudied joint. We have identified which peri-articular tissues contribute to PTJC and elucidated temporal patterns of pathogenesis. We have also utilized several longitudinal evaluation techniques to quantify the functional impact of PTJC over time. Ongoing work is investigating the ability of physical therapy or biological treatments (i.e., drug or cell based) to reduce the fibrotic tissue response and prevent motion loss following injury. Long-term, this work will improve fundamental understanding of joint health and help guide translatable treatment strategies for PTJC in the elbow and other joints.

Talk: More to the Story: How Bony Deformity Changes Muscle Mechanics at the Hip

Abstract: Developmental dysplasia of the hip (DDH) dramatically increases risk for early hip osteoarthritis by altering joint mechanics. Bone shape and cartilage stress have traditionally been the focus of hip biomechanics investigations, but they not the only major factors in joint loading. We investigate relationships between abnormal bone in DDH and other major contributors to joint loading, namely muscle-driven forces and motion. In this talk, I will report how our studies combining in-vivo biomechanics, magnetic resonance imaging, and in-silico simulation have recently identified important differences between patients with DDH and healthy controls that may contribute hip joint damage. I will share how we use techniques developed within engineering disciplines, such as musculoskeletal modeling, to clarify the role of muscle in DDH symptomatology, mechanics, and joint damage to inform optimized treatment strategies.

Talk: Prostate Cancer: Prevention and Treatment

Abstract: Prostate cancer remains the most common cancer in men and is a major cause of cancer-related death, despite the recent advances in treatment. Metastasis is the significant cause of morbidity and mortality in prostate cancer and approximately 90% of patients die with metastasis. Carcinogenesis and metastasis are multi-step processes and understating the signaling pathways will help in developing future treatment modalities. The intervention of multistage cancer by modulating intracellular signaling pathways may provide a molecular basis for chemoprevention with a wide variety of dietary phytochemicals. Therefore, an ideal approach to inhibit the progression of cancer is to induce cell-cycle arrest or apoptosis using dietary chemopreventive compounds.  We have observed that bitter melon can be utilized as a dietary supplement for prevention in prostate cancer. In fact, oral administration of bitter melon significantly inhibits prostate cancer progression in a preclinical model without any adverse health effects, and can be utilized as dietary supplement for prevention of prostate cancer.
microRNAs (miRNAs) play a critical role in multi-step cell growth regulatory mechanisms. Revealing the function of miRNAs as potential oncogenes and tumor suppressors has generated great interest in using them as targets for cancer therapies and we demonstrated that miR-29b can be used as a potential therapeutic agent. Therefore, natural compounds and microRNAs are potential strategies for preventing and treating prostate cancer along with conventional therapy. 

Bio: Dr. Ratna Ray did her PhD from the University of Calcutta, India, in 1985. She has her post-doc training in the University of Alabama at Birmingham.  She joined Saint Louis University as an Assistant Professor in 1993, and rose to the rank of Professor in 2005. Dr. Ray’s laboratory is engaged in cancer biology work.  She showed that natural product (bitter melon) has anticancer activity.  She is investigating its role in tumor microenvironment including immune modulation using prostate, oral and breast cancer model systems. Recently, her laboratory initiated work on non-coding RNA regulation, and currently plans to understand the relationship between microRNAs and cancer therapy.
Dr. Ray is working to understand the mechanisms of hepatitis C virus persistence and end stage liver disease progression in humans. Her research group made a significant contribution in understanding the cross-talk between HCV and host cell factors in disease progression.  She is interested in identifying non-invasive biomarkers for early detection of HCC from different racial/ethnic patients.

Talk: Study of Drying Shrinkage Mitigating Concrete using Large-Scaled Bridge Decks

Abstract: Cracks in concrete bridge decks shorten the life of deck by providing easy access for deicing chemicals. Most of the bridge decks suffered from early age transverse cracking due to drying shrinkage. This study experimentally investigates the effects of restrained drying shrinkage on bridge decks using 10ft. x 7ft. experimental concrete slabs designed to simulate a portion of a bridge deck. The large-scale experimental bridge decks used in this study was designed to closely replicate the restraint found in the field. Total six different concrete mixtures are evaluated including: (1) a mixture containing 100% portland cement, (2) a mixture incorporating Type-K cement, (3) a mixture containing partially saturated lightweight aggregate (LWA) to promote internal curing, (4) a mixture containing shrinkage reducing admixture (SRA), (5) a combine mixture of Type-K cement and internally cured LWA and (6) a combine mixture of Type-K cement and Gypsum. This study investigates the effectiveness of above-mentioned concrete mixtures to reduce concrete shrinkage and subsequent cracking.

Talk: Quantitative Sustainable Design and its Application to Water and Sanitation Infrastructure

Abstract: Quantitative sustainable design, a process of mechanistically linking design and operational decisions to sustainability indicators, can inform decision-making for water and sanitation infrastructure by enabling navigation of trade-offs across dimensions of sustainability (e.g., environmental, economic, human health). This process can help decision-makers target specific design and operational improvements, influence policies, and prioritize future research needs to advance infrastructure sustainability. However, to be useful for decision-making, sustainable design tools must address context-specific objectives and constraints. This presentation will provide an overview of the process of applying quantitative sustainable design tools to water and sanitation infrastructure systems, specifically addressing critical barriers for the practicality of two tools – life cycle assessment (LCA) and quantitative microbial risk assessment (QMRA) – in two different contexts. Finally, future opportunities for advancing quantitative sustainable design for engineering decision-making, such as incorporation of social factors, will be highlighted.

Talk: Community Rooted Green Infrastructures for Sustainable Stormwater Management

Abstract: Urbanization has made significant impacts on the natural environment. Green space and permeable land surfaces were lost to impermeable covers such as roads and roofs. The changes resulted in a large increase of peak flows and volume of storm runoff leading to severe urban water management problems such as blocked hydrologic pathway to groundwater, impaired characteristics of urban watersheds, accelerated mobilization of pollutants and erosion, damaged ecosystems, and threatened public health. Green infrastructure integrates stormwater management with landscaping, offering a holistic solution to urban stormwater problems. This presentation will introduce the issues and challenges of urban stormwater management, describe the current efforts and programs to address urban water problems, discuss findings and experience of a number of recent research projects by the presenter’s research group, and link research with engineering application, community development, and public education.

Talk: Winds of Change: The Future of Unmanned Aircraft in Weather

Abstract: Unmanned Aircraft Systems, aka drones, have been proposed for use in a number of areas outside of traditional reconnaissance, including agriculture and infrastructure modeling. Additional civilian applications that are being explored include weather and wildfire monitoring. Researchers at OSU have partnered with NOAA and partner universities through the CLOUD-MAP project to develop and use UAS to help increase our understanding of tornado genesis with the goal of increasing the forecasting capability and warning time of severe storms and deadly tornadoes. While the primary goal is to take measurements that will increase our knowledge of how these storms form, they will also track cyclones as they develop. This will provide information currently only obtainable by storm chasers who put themselves directly in the path of the storm. Future use of UAS will enhance storm-chasing capabilities while allowing the chasers to maintain a safe distance from the storm. The same systems can be used to search for survivors after a storm and perform immediate post-tornado damage assessment. UAS can also be used to obtain data from wildfires to develop better computational models to predict how fires form and behave. These models will help us understand how fires evolve to allow emergency services to contact residents and businesses that may be located in the path of the fire, saving lives and property. This talk explores some of the work currently being done in these areas as well as discuss the future of autonomy, including swarms and driverless cars.

Talk: Why Composites?

Abstract: Composite materials, commonly shortened to composites, are materials made from two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material emphasizing the best qualities of the constituents. The disadvantages of the individual constituents are overcome by the presence of the other constituents. While each constituent retains its separate chemical, physical, and mechanical properties, properties that no constituent exhibits in and of itself are created by the interaction of the individual constituents. The new material may be preferred for many reasons over traditional materials: performance improvements, lower manufacturing cost through part reduction, and supportability improvements.  Renieri will overview his experience with composites, discuss applications of composites, and current and potential uses of composites in aerospace, infrastructure, transportation, sporting goods, marine product, and biomedical applications.

Essential to utilizing composites is the understanding of their behavior based on materials selected, fabrication process, structural environment, and cost.  Renieri will discuss a potential course “Mechanical Behavior of Composites” to be offered in the 2019 fall semester. The course is designed for seniors and graduate students little or no knowledge of composites. The goal of this course is to provide a sound foundation in the Constitutive relations (A, B, D matrices) for both lamina (single layer) and laminates (multiple combined layers). This foundation is applicable to all aspects of product development engineering disciplines: Structures, Design, Materials and Processing, and Manufacturing. The course provides an overview of Design Principles - dos and don'ts.  Those in the following engineering degree programs would benefit:  aerospace, mechanical, biomedical, civil, and engineering mechanics.

Bio: Renieri has been an active adjunct professor since 1989 in the Mechanical Engineering Department at Washington University, where he teaches a course in the mechanical behavior of composite materials.  He has also participated in many Ph.D. review panels at Washington University.

Renieri has published over 70 papers and significant company reports in the areas of composite design, analysis and testing, ballistic testing and damage assessment of composite structures, composite structures repairs and associated analysis techniques, and affordable manufacturing methods.

During his nearly 40 years at Boeing, Renieri either lead or was part of many Boeing sponsored composite training courses as part of offset credits. These efforts have included assignments in Italy, Finland and the Netherlands and the training of engineers from Malaysia, Saudi Arabia and Korea at the Boeing facility in St. Louis.

Talk: Modeling Inherited Disease and Cardiotoxicity Using Engineering Micro-Heart Muscle Derived from Human Induced Pluripotent Stem Cells

Abstract: Stem cell technology holds immense potential for tissue replacements therapies and for guiding drug development. However, these possibilities are hampered by challenges in controlling transplanted cell fate, and the limited prognostic capabilities of overly simplistic in vitro models.

His lab uses biomaterials and bioengineering approaches to overcome both sets of challenges. In this talk, Dr. Huebsch will focus on his work on engineering tissues from Human Induced Pluripotent Stem Cell (iPSC) derived cardiomyocytes (iPS-CM) in order to study how mechanical cues synergize with genetics and drugs to influence cellular physiology and molecular signaling. When they culture iPS-CM in “tissue-like” micro-environments, the ability to model inherited diseases related to sarcomere mutations (MYBPC3) is enhanced. Importantly, mechanical cues (afterload) influence the genotype-phenotype relationship. In miniaturized tissue models, they can also enhance iPS-CM maturity by altering the metabolic environment (ATP source), whereas the same soluble signal has no discernible effect in 2D culture. To carry out this multidisciplinary work, his lab uses technologies from molecular biology, image processing, micro-fabrication and tissue engineering.

Finally, Huebsch will discuss his lab’s current efforts to use iPS-CM micro-tissues to study inherited arrhythmogenic disease, including the development of high-throughput methods for controlling iPS-CM tissue mechanical loading, and to integrate these tissues with micro-electrode arrays (MEA) to facilitate continuous monitoring of tissue electrophysiology. 

Bio: Huebsch did his B.S. in bioengineering at UC Berkeley, where he did research on biomimetic hydrogels with Kevin E.

Talk: Analysis of Inter-Rotor Coupling in a Coaxial Rotor System

Abstract: The development of the finite-state method and inflow models over the last 50 years have made them ideal solutions for induced flow in rotorcraft because inflow models explain the physics of the dynamic behavior and are designed in a hierarchical nature to incorporate previous models. Inflow models are computationally less expensive than CFD and vortex-lattice method (VLM) solutions and can even be calculated in real-time. Until the application of the Adjoint Theorem in 2012, only the flow on and above the rotor disk could be studied with finite-state models. The Adjoint Theorem has now made it possible for analysis of flow below the rotor disk and investigation of multirotor systems and the resultant coupled dynamics.

In this talk, Seidel will present work on the application of existing finite-state potential flow models (including the Adjoint Theorem) to the coupled inflow and rotor dynamics of coaxial rotor systems. Because the Adjoint Theorem involves coupling of rotor and inflow state with adjoint rotor states (including pure time delays in both types of variables), the resultant coupled dynamics experiences characteristics previously not studied in a dynamic system. In order to study this new behavior, this present work first introduces a dynamic inflow model that does more than compute the flow on a given rotor (as is done with most inflow models). Rather the model must compute for each of two interacting rotors:  the flow above each rotor and the flow below the upper rotor. This must be done so that the effect of the lower rotor on the upper (and of the upper rotor on the lower) can be found in a flight simulation.

Bio: Seidel is currently Ph.D. candidate at Washington University in St. Louis where he began his studies in January 2017. Prior to attending Washington University, he received his B.S. and M.S. degrees in mechanical engineering from Saint Louis University. His master’s thesis focused on bio-inspired wind turbine design with Dr. Sanjay Jayaram. His Ph.D. dissertation work focuses on the development of finite state inflow models for coaxial rotor systems to model rotor coupling and dynamics. Outside of academic studies, Seidel has spent four summers as a research intern at Wright-Patterson Air Force Base. His work focused on uncertainty quantification in fatigue life specimens and artificial target generation and data scoring analysis using machine learning algorithms. His other research interests include computational fluid dynamics, wind energy, urban renewable energy, and machine learning. He is a member of Tau Beta Pi, the Vertical Flight Society, AIAA, and an InSITE Fellow.

Talk: Artificial Intelligence, Big Data, and Computer Simulation in Construction

Abstract: Although the engineering and construction sector stands as one of the largest industries in the world, it remains one of the least efficient. It also is one of the least digitized industries in the world, ranking second to last in the USA. Overall, 98% of capital projects run into schedule delays and/or overruns. Large, complex projects are tough to manage using traditional CEM tools and techniques. Computer simulation has shown itself to be quite effective in designing, analyzing, and optimizing construction processes regardless of the complexity or size of projects. Additionally, IoT, Big Data, and Machine Learning can play a significant role in using production data to improve construction process productivity and predictability. This presentation aims at surveying, briefly, the different computer modeling and simulation techniques and applications that have been found to be quite effective on a number of different construction processes; describing a construction industry-first artificial intelligence/machine learning application to predict construction equipment performance; and  present a real-life case study of the application of computer simulation and machine learning at a mega construction project with substantial monetary savings.

Talk: Thermodynamic Potential Analysis and Phase Field Simulations of BariumZirconate Titanate Solid Solutions


Abstract: Barium Zirconate Titanate [Ba(ZrxTi1−x)O3] solid solutions are promising lead-free ferroelectric materials with switchable polarization, excellent dielectric, piezoelectric, and pyroelectric properties. These materials have received substantial interest, with a wide range of applications in memories, capacitors, actuators, sensors, and electrocaloric cooling devices.

Thermodynamic analysis based on phenomenological Landau-Devonshire theory is a powerful method for theoretical investigation of ferroelectric materials, but cannot be applied to Ba(ZrxTi1−x)O3 because there is no thermodynamic potential. In this presentation, a thermodynamic potential for Ba(ZrxTi1−x)O3 (0 ≤ x ≤ 0.3) solid solutions is constructed, and a thermodynamic analysis then is carried out. The results accurately reproduce known phase structures and their transition temperatures, and there is good agreement with experimentally measured polarization, dielectric and piezoelectric constants. It is found that Ba(ZrxTi1−x)O3 solid solutions at room temperature have three phase boundaries, including a tetragonal-orthorhombic phase boundary at x = 0.013, an orthorhombic-rhombohedral phase boundary at x = 0.0798, and a rhombohedral-paraelectric phase boundary at x = 0.2135. The results also indicate that the chemical composition-induced ferroelectric-paraelectric phase boundary has superior electromechanical properties, suggesting a new way to enhance electromechanical coupling in Ba(ZrxTi1−x)O3 solid solutions.

With the thermodynamic potential of Landau-type for Ba(ZrxTi1−x)O3 constructed, phase field simulation, another promising computational tool for materials at micro- and meso- scales, is developed and implemented to study possible formations of domains with multiple phases at representative temperatures, including cubic, tetragonal, orthorhombic and rhombohedral phases, as well as phase transformations across these temperatures.

Talk: Advances inMultiframe Blind Deconvolution for Ground Based Telescopes


Abstract: Ground-based space telescopes contend with atmospheric turbulence that blurs and distorts imagery.  Adaptive optics (AO) reduce these effects by sensing the wavefront phase disturbances and automatically adjusting deformable mirrors that compensate for the disturbances.  Even so, deconvolution algorithms and software are needed to clarify the imagery.  This is because of residual optical and atmospheric turbulence aberrations.  Recent advances are presented for multiframe blind deconvolution (MFBD) of ground based telescope imagery for low-earth orbit objects. The iterative algorithm uses the maximum likelihood estimation optimization criterion. It is modeled from a previous well-known algorithm called the expectation-maximization (EM) algorithm. New renditions of the algorithm simplify the phase reconstruction, thereby reducing the complexity of the original EM algorithm. Examples are shown, with and without adaptive optics (AO).  The system is being designed for on-the-fly streaming video operation.

Talk: Mechanisms of Replication Stress Response to Chemotherapeutics


Abstract: Aberrant DNA replication is one of the leading causes of mutations and chromosome rearrangements associated with several cancer related pathologies. At the same time, agents that stall or damage DNA replication forks are widely used for chemotherapy, in the attempt to selectively target highly proliferating cancer cells. We showed that replication fork reversal is a pivotal mechanism of replication stress response to chemotherapeutics that allows cancer cells to withstand DNA damaging chemotherapy. Our recent progress toward the understanding of factors involved in the formation and protection of reversed replication works will be discussed. These studies provide important clues on enzymes that can be targeted to prevent fork reversal and increase chemotherapy sensitivity.

Bio: Vindigni received a Ph.D. in biochemistry and molecular biophysics from the University of Padua (Italy) and completed his postdoctoral training at Washington University School of Medicine in St. Louis. In 2002, he was appointed Group Leader in Genome Stability at the International Centre for Genetic Engineering and Biotechnology (ICGEB) in Trieste, Italy. In 2011, he relocated his lab to the Saint Louis University School of Medicine, where he was promoted to full professor with tenure and nominated director of the graduate program in biochemistry of Saint Louis University in 2014. Since 2015, he has been serving as co-leader of the DNA Metabolism and Repair (DMR) program of the Siteman Cancer Center at nearby Washington University, which provides a unique platform for scientists who work in the closely related areas of DNA damage response, DNA replication and repair, chromatin biology, and gene regulation. His laboratory focuses on the mechanisms of DNA replication and repair, and on the possible strategies to target these mechanisms for cancer treatment. His work defined new, important mechanisms for maintaining genome integrity and is currently supported by grants from the National Institutes of Health and Breast Cancer Research Program of the Department of Defense.

Talk: Mechanobiology of Epithelial Cells in Physically Heterogeneous Environments

Abstract: The ability of epithelial cells to move through complex tissue barriers fundamentally regulates important physiological and pathological phenomena, such as embryogenesis, organ development, wound repair, and tumor metastasis. In pathogenesis, including fibrosis and cancer, matrix stiffening is known to induce epithelial-mesenchymal transition (EMT) and enhance cell migration in clustered epithelial cells. These processes result from a complex interplay of epithelial cells with physically heterogeneous extracellular matrices (ECMs) of varying stiffness and topography, spanning over multiple scales of time and space. In this presentation, I will discuss two broad topics within my research group – the induction of EMT due to matrix confinement and physical defects; and the role of mechanical memory in cell migration. Topic One: We fabricate hydrogel-based microchannels to show that epithelial cells express EMT markers in more confined channels, even in soft ECMs that otherwise protect against such mechano-activation. Through experimental measurements and computer simulations, we show that cell spreading and elongation along channel walls is essential for this confinement-sensitive EMT. In a related project, we show that physical defects in a basement membrane-like soft matrix induce EMT, which is distinct from the known mechanosensitive EMT due to matrix stiffness or topography. Topic Two: We interrogate whether priming of epithelial cells by a given matrix stiffness influences their future migration on a different matrix. Through experimental results and computational modeling, I will discuss how YAP-dependent mechanical memory and dynamic mechanotransduction enable the collectively migrating cells to sense matrix stiffness of both past and present.
