George B. Witman symposium
Beautiful Zoom event on January 20, 2021 (organized by Greg Pazour and Steve King)
January 6, 2021: A beautiful day in Georgia! No surprises in DC.
The end or just the beginning? Why do we still have a commencement prayer at UGA?
It's official. And here are the pictures to prove it.

Welcome to our summer students
Heather Bomberger (Virginia Tech) and Aachi Kalra (Northview High School, Johns Creek, GA) spend the summer in the lab on research interships.
Heather Bomberger, a sophomore in Biological Systems Engineering and minoring in Scieneering, participates in the NSF-sponsored REU program “Interdisciplinary Research Experience of Nanotechnology and Biomedicine” at UGA. Her project "Quantitative Analysis of Intraflagellar Protein Transport” is co-mentored by Dr. Peter Kner from UGA's College of Engineering.
Aachi Kalra participates in UGA's Young Dawgs programm, a high school internship program designed to prepare high-achieving high school juniors and seniors for post-secondary education and future careers in their areas of interest. Aachi Kalra is interested in biomedicine; during her intership she will rescue the ift54-1 mutant using a GFP-tagged IFT54 transgene.
Fiona Bell and Deep Patel, the first undergraduates to join the lab in 2012, have graduated.
