J. Crozier Profile
Dr. J. Brooks Crozier
B.S., Roanoke College; M.S., Ph.D., Virginia Polytechnic Institute & State University. 1999
Research & Teaching Interests
Microbiology, Mycology (fungi), Phycology (algae), INQ 250(about the microbiology and ecology of soil), INQ 300 (gives students an opportunity to learn about learning and solve a problem in the sciences).
Microbial Source Tracking, including detection of virulence and host-specific DNA markers; performance criteria for such markers; and their application in target-oriented water resource management.
Sabbatical (Spring 2013) worked on several projects at Virginia Tech and spent April, May and part of June 2013 in the lab of Dr. Andreas Farnleitner, Vienna Austria.
