Postdocs
Monsurat M. Lawal
Monsurat Lawal graduated from University of KwaZulu-Natal, South Africa in 2016 and 2019 with Masters and PhD degrees, respectively, in Pharmaceutical chemistry (computational and theoretical option) under the supervision of Prof. Hendrik G. Kruger and Dr. Bahareh Honarparvar.
She obtained her first degree in Biochemistry at Ekiti State University, Nigeria in 2012.
Her PhD project involves a computational understanding of the mechanism of action of the HIV
protease, including two drug resistant mutants where she theoretically explored the concerted mechanistic models of this enzyme.
Graduate students
Yi Zheng
Yi Zheng graduated from University of Iowa in 2019 with a Bachelor of Science in Biochemistry and a Bachelor of Art in Chemistry.
Her undergraduate research in Dr. Ned Bowden’s group focused on the synthesis of polydiaminosulfides for application in drug delivery.
Her undergraduate research with Dr. Stefan Strack involved structural and functional characterization of mitochondria fission factor (Mff).
She is now a first-year graduate student at Virginia Tech.
