I am a post-doctoral fellow working with Dr. Vaughn Cooper at the University of Pittsburgh. I use microbial experimental evolution to study interactions between evolutionary and ecological processes. Because of the large population sizes and fast growth of bacteria, we can observe how the bacteria evolve in experiments in the laboratory.

   Currently I am studying the evolution of biofilm formation and the factors that drive diversification into coexisting types with distinct ecological strategies. My work is supported by a NASA post-doctoral fellowship and the NASA Astrobiology Institute.

    I completed my Ph.D. in Dr. Richard Lenski's lab at Michigan State University, where I worked with the long-term evolution experiment with E. coli. This experiment has continued for over 20 years and more than 50,000 generations.

I recently helped organize the first ever Three Rivers Evolution Event in Pittsburgh, PA. Keep your eyes out for TREE 2018!
