As we begin a new semester on campus, there are many great things happening across the College of Science community.

Dr. Martha Bhattacharya studies fruit flies to learn how brain cells respond to injury and stress. Her research looks at how neurons survive damage from things like nerve injuries, disease, and even some cancer treatments. She will share how discoveries in flies can lead to clues for protecting the human brain in her 2026 Lecture Series talk on February 11 at Centennial Hall.
