Alican Demir defends his PhD thesis

alican_defense

On Thursday December 11 Alican Demir presented his PhD dissertation research to a packed seminar room at Johns Hopkins. Alican joined the lab as a Freshman in 2013, performed MSE thesis research in the lab, worked as a research specialist for a few years, and then completed his PhD, so his contributions have been monumental in shaping the LIMBS laboratory over the years. Congratulations Alican!
