Kate Fee
High School Research Assistant
While in the Levin lab, Kate combined microscopy and high throughput image analysis to determine the length and width of bacteria cultured under different nutrient conditions. Kate is currently attending UMKC's six year BS/MD program and working as a research assistant in Dr. Prachee Avasthi's laboratory at KUMC (http://www.avasthilab.org/).
