Muruleedhara Byappanahalli

Biography

Murulee Byappanahalli, Ph. D. is a Research Microbiologist with the U.S. Geological Survey Great Lakes Science Center.  He received his MS and Ph. D. degrees in Microbiology from theUniversity of Hawaii at Manoa.  His research interests include microbial ecology, soil microbiology, and water quality and public health microbiology.  He is the team leader for microbiology program in his research group. He has published extensively on the ecology of indicator bacteria (E. coli, enterococci) in natural environments, such as soils and sediments, beach sand, and aquatic vegetation.  His research was among the first to document the natural occurrence, persistence, and growth of indicator bacteria in nonenteric habitats.  Byappanahalli’s other research interests include exploring gene-based (molecular) techniques for identifying sewage markers in environmental waters.  He is a member of the American Society for Microbiology and Society for Applied Microbiology.  He has adjunct faculty positions at Purdue University (North Central) and Indiana University (Northwest).
