Meet our current medical physics residents!

Senior Residents (Graduating 2019)


Zeynep Karakas, M.S.

Zeynep is a second year resident from the Washington, D.C. area. She is a proud Terrapin at heart, having earned her B.S. from the University of Maryland in 2014. She completed her M.S. in Medical Physics from the University of Toledo in 2016 and started working as a Junior Physicist for about a year before joining UNC as a resident. Some of her favorite things to do include stargazing Carolina’s dark skies with friends, window shopping NYC’s fashion district, and reading Elon Musk’s twitter feed.


Lan Lu, Ph.D.

Lan obtained her Ph.D. from the Department of Biomedical Engineering at Washington University in St. Louis. Before she joined therapy side of medical physics, she conducted several years of MRI research and held a junior faculty position at Case Western Reserve University. In 2016, Lan joined Cleveland Clinic as a research fellow to start her formal training in the therapeutic medical physics. In her free time, Lan enjoys exploring North Carolina’s natural beauty. She likes the fact that Chapel Hill is so close to mountains and oceans, and spends holidays exploring these places with her family.


Junior Residents (Graduating 2020)


Jeffery Fenoli, M.S.

After growing up in Seattle, Jeff studied physics at the University of British Columbia. He studied physics in undergrad and then worked as an intern for Northwest Medical Physics Center, where he commissioned machines, performed QA, and conducted research. For his Master’s degree, he moved across the country to study at Duke University. In graduate school, he focused on Monte Carlo simulations of dose in fluoroscopy and CT, under the guidance of Dr. Anuj Kapadia. In his free time, Jeff likes to DJ, lift weights, and play board games. His favorite thing about the UNC residency has been the excellent training in dosimetry and treatment planning.


Ryan Pappafotis, M.S.

Ryan is a junior resident born and raised in Georgia. He graduated with a B.S. in Physics from the University of Georgia– Go Dawgs! At UGA, he played competitive Ultimate Frisbee and trombone in the marching band. After undergrad, Ryan attended Duke University, where he received his M.S. in Medical Physics. His current favorite hobby is playing disc golf around Durham and Chapel Hill.
