Dr. Rosa Krajmalnik-Brown is currently an assistant professor in Civil and Environmental Engineering and is part of the Center for Environmental Biotechnology in the Biodesign Institute. Dr Rosa Krajmalnik-Brown received her bachelor’s degree in Industrial Biochemical Engineering from the Universidad Autonoma Metropolitana (UAM) in Mexico City in 1996. She worked for a year at IBTech, an Environmental Engineering consulting firm and in 1997 she was awarded a Fulbright scholarship which she used to get her master’s degree at Georgia Tech. She completed her Ph.D. in Environmental Engineering at Georgia Tech in August of 2005. She is author of a patent, several peer-reviewed publications and has presented numerous talks and posters at national and international conferences.


Biotransformation and fate of environmental contaminants with an emphasis on environmental applications of molecular microbial ecology. Other areas of interest include bioremediation of soil, sediments, and groundwater and the use of microbial systems.
