Jeffrey Brown, Ph.D.

Assistant Professor

The primary goal of Dr. Brown’s research is to increase the well-being of both wildlife and people through urban ecological conservation and the incorporation of ecological infrastructure into urban design. Dr. Brown’s research focuses on three central questions:
1. How does wildlife use urban ecological infrastructure and what are the implications for conservation?
2. How do people, through both indirect and direct interactions, shape wildlife distribution and how do people’s behaviors and values relate to their actions toward wildlife?
3. How can community collected data better increase understanding of human0wildlife interactions?

To answer these questions, Dr. Brown combines both computational models, field experiments, social surveys, and the use of community collected and publicly available datasets.

Before coming to La Salle, Dr. Brown was a postdoctoral research associate and lecturer at Arizona State University (ASU). At ASU, Dr. Brown worked with the Central Arizona-Phoenix Long-Term Ecological Research Project (CAPLTER) studying human-wildlife interactions. Dr. Brown is currently senior personnel at CAPLTER and the assistant-director of the Phoenix Area Social Survey. Dr. Brown received his Ph.D. in from Dr. Julie L. Lockwood at Rutgers University. At Rutgers, his dissertation focused on ecological community dynamics in urban forest fragments. Prior to attending Rutgers, Dr. Brown received his B.S. in ecology and evolutionary biology from Rice University where he worked with Dr. Haldre Rogers and the Ecology of Bird Loss Project.

In addition to his research interests, Dr. Brown enjoys training Brazilian jiujitsu, climbing, cooking, and playing with his dog Beaker.
