B.S. in Biochemistry: University of Delaware, 2017
Fun fact: I can start a friction fire in under 6 seconds (bow drill)!
Harry is studying the reversible chemistry of quinone methides. He is examining the interactions between molecular machines and reversibly cross-linked DNA.
Daniel Lemen
5th Year Graduate Student, Chemistry Department
Hometown: Frederick, MD
M.A. in Chemistry: Johns Hopkins University, 2020
B.A. in Biochemistry: Messiah University, 2018
B.A. in Spanish: Messiah University, 2018
Daniel is studying whether substrate structure is able to alter the redox chemistry of iodotyrosine deiodinase (IYD). He is also working to elucidate IYD’s mechanism of catalysis by synthesizing substrate analogues.

Ekroop is studying how cofactor replacement can manipulate the enzymatic activity of Iodotyrosine Deiodinase (IYD).
Crystal (Yu-Ju) Peng
2nd Year Graduate Student, Chemistry Department
Hometown: Hsinchu, Taiwan
M.S. in Chemistry: National Taiwan University, 2020
B.S. in Chemistry: National Taiwan University, 2018
Crystal is studying azoreductase-sensitive prodrugs. She is currently working on the designs that generate aza-quinone methides (aQMs) as a warhead to target biomolecules in the presence of azoreductase.
