Assistant ProfessorBiological Sciences
Anna Snyder Jozwick is an Assistant Professor of Biological Science in the Center for Natural Sciences at Goucher College. She completed her Ph.D. in Biology, with a specialization in molecular and microbiology, in 2013 at West Virginia University. Prior to her arrival at Goucher, she was a Post-Doctoral Research Microbiologist at the National Center for Cool and Cold Water Aquaculture (United State Department of Agriculture, Agricultural Research Service). At Goucher, she teaches a broad range of biology and environmental science courses for both majors and non-majors. She is also actively involved in science outreach. Jozwick’s research focuses on understanding the genetic basis microbial species interactions with one another and their animal host. Her lab combines classical microbiology with continually evolving molecular techniques to examine how agriculturally-important microbes evolve in response to host defense, human intervention and environmental change.
Research, Scholarship, Creative Work in Progress
The current area of research aims to identify and understand factors involved in the communication and virulence of Yersinia ruckeri, a pathogen affecting farmed rainbow trout. This bacterium causes hemorrhagic septicemia and death, if left untreated. While a vaccine is currently in use, disease outbreaks still occur, leaving open the need for alternative control measures. By understanding the signals and genetic responses of communication (i.e. quorum sensing), we will learn how these processes impact persistence within the environment and the fish host. Broadly, the goal of Prof. Jozwick's research is to identify factors and microbial capabilities that can be exploited for novel control strategies.
