Faculty Joe Szewczak Biological Sciences

Dr. Joe Szewczak, Biological Sciences Dept., was recently featured in the October issue of the California Educator Magazine The article discusses the "Real Bat Man", as Dr. Szewczak teaches, among other courses, Biology of Chiroptera, which is the study of bats. Dr. Szewczak has studied many bat species, looking at migration patterns, social communication, endangered species, and how to reduce fatalities caused by energy-producing wind turbines. He and his colleagues recently completed a two-year trial that provided high-intensity ultrasound emitted from turbines can steer bats away from death.

Student Sara Downey Biological Sciences

Last week a CSU team made public comments in support of the California Institute of Regenerative Medicine (CIRM) Bridges program. Former HSU Biology Major/CIRM Bridges Scholar, Sara Downey’s presence at last week’s meeting was electric because most everyone in the room knew she’s on a team developing an embryonic stem cell-derived product as a treatment for type 1 diabetes. After four years on the job, Sara has transformed from a fresh biological sciences graduate with academic research experience into a biotech professional comfortable talking about Six Sigma, cGMPs, regulatory affairs, biotech business cycles, & process engineering. The CIRM board has extended the program for one year.
