Research Interests: My research focuses in understanding the role that space has on ecological processes and structures. Most of his work centers around populations and communities of bee pollinators in urban environments. Over half of all the human population already live in cities, and is expected that by 2050 two out of every three people will live in a city. Understanding how ecosystem services, like the pollination of crops, is affected by the urban environment is of crucial importance. Cities are complex structures comprised of industrial, residential and green spaces of different sizes across a network of roads, sewers, power lines, etc. Furthermore, differences in social, economic and cultural status also affects how people use and alter ecosystem processes in cities. Our work has shown that bees in St. Louis city are responding the many of these parameters.

Research Opportunities: There are several research opportunities for students in my lab. Biodiversity distribution in green public spaces in relation to income inequalities, Ecology of insect-plant interactions in tropical systems and Statistical ecology of vector species.
