At the age of 40 and nearly 20 years into a career in health care administration, a David Attenborough nature documentary seismically shifted the life of Deby Cassill. "I realized sitting there that I didn’t just want to watch science, I wanted to do science,” Cassill said. By the time she was 50, Cassill had earned a doctorate in the field and in 2001, was hired on as the first full-time biology professor on the USF St. Petersburg campus. Now she is providing the institution with a $1 million estate gift to create the Cassill Endowed Scholarship in Biology to aid the next generation of aspiring biologists.
