Dr. Robin R. Rohwer

Research Fellow, Baker Marine Microbial Ecology Lab, Department of Integrative Biology
The University of Texas at Austin

Two Decades of Microbial Ecology and Evolution in a Freshwater Lake

Dr. Rohwer is an NSF-funded Postdoctoral Fellow at The University of Texas at Austin in the Baker Microbial Ecology Lab. Specializing in freshwater microbial ecology and evolution, she uses DNA sequencing to explore how bacterial communities in lakes change both ecologically and evolutionarily over time.

Dr. Rohwer earned her Ph.D. in Environmental Chemistry and Technology from the University of Wisconsin–Madison, where she was involved in a study of Lake Mendota’s microbial communities. Her doctoral work provided valuable insight into how microbial genomes evolve and respond to ecological pressures. In addition to her current fellowship at UT Austin, Dr. Rohwer has held a postdoctoral role at the DOE Joint Genome Institute, expanding her expertise in large-scale metagenomic analysis.

Dr. Rohwer has published extensively—covering themes from bacterial evolution in nature to viral dynamics in lake ecosystems. Her work has been featured in outlets including Al Jazeera, HPC Wire, and Madison Magazine and she has shared her findings on podcasts and radio.
