Research Interests

My research interests are in the area of synthetic medicinal chemistry. We design and synthesize molecules using state of the art techniques. We focus on multi-disciplinary collaborative projects to develop new tool and therapeutic compounds to probe complex biological systems. Currently, we are focused primarily in two areas: development on novel modulators for nuclear receptors and development of methods and strategies for targeting Gram-negative bacteria. Prior to coming to academia, I worked in the pharmaceutical industry leading discovery projects in a variety of therapeutic areas.
