    Catherine Volle

    Assistant Professor of Biochemistry



Biographical Sketch

Catherine became interested in science at age 10 when she decided to become a veterinarian. She remained on that career path throughout her time as an undergraduate at Mount Holyoke College. It wasn't until the beginning of her second year as a research associate, studying the biophysics underlying predation by the bacteria Bdellovibrio bacteriovorus, that she decided to get her Ph.D. rather than a DVM. She applied to graduate programs intending to study marine microbiology; however, she chose to attend Brown University’s program in Molecular and Cellular Biology and Biochemistry because she was impressed by the exciting basic science that was taking place. She joined the laboratory of Dr. Sarah Delaney in the Brown chemistry department, where she studied the effect of oxidative damage on hairpin DNA and the behavior of trinucleotide repeats in the nucleosome.  

After completing her degree at Brown, she moved to the National Institutes of Health to continue studying chromatin. In her first year, she was awarded the Sally Rosen Kaplan fellowship for women in cancer research. During her time at the NIH, she realized that she did not like being at a big research institution and that she would be much happier teaching and researching with students. She served as an adjunct professor at Georgetown University and Trinity Washington University and joined the faculty at Cottey College in 2015. She moved to Cornell in 2019.  

Catherine's lab studies the biomechanical changes that occur when bacteria are treated with antibiotics. They also investigate the ability of viral proteins to destabilize DNA folded into a hairpin. Further information on the Volle lab can be found at https://thevollelaboratory.net/.
