About and News


Aditi Bhaskar is an Assistant Professor in the Department of Civil and Environmental Engineering at Colorado State University.  Dr. Bhaskar specializes in changes to water resources that accompany urban development, with a focus on interactions between streams, groundwater, stormwater, and urban irrigation.  Dr. Bhaskar received a Sc.B. in Geology-Physics/Math from Brown University and a Ph.D. in Environmental Engineering from University of Maryland, Baltimore County.  Dr. Bhaskar was a trainee of the National Science Foundation Integrative Graduate Education and Research Traineeship (IGERT) in “Water in the Urban Environment” at University of Maryland, Baltimore County.  Then, Dr. Bhaskar was an National Science Foundation Earth Sciences Postdoctoral Fellow, which took her to the U.S. Geological Survey in Reston, Virginia, before joining Colorado State University.  Dr. Bhaskar is a recipient of the National Science Foundation CAREER award and serves on the Board of Directors of CUAHSI.
