Lily Hale

Lily was born and raised near Seattle, WA. She received her B.Sc. in chemistry at Western Washington University, where she was introduced to organometallic chemistry working with Prof. Tim Clark on Ir-catalyzed C-H borylation reactions. In 2013 she began doctoral studies under the direction of Prof. Nate Szymczak at the University of Michigan. Her graduate work focused on developing new strategies for Ru-catalyzed hydrogenation reactions of amines and nitriles. During her Ph.D. studies she was also a visiting student in the lab Prof. Ruben Martin at ICIQ in Tarragona, Spain, where she learned about the mechanisms and reactions of Ni-catalyzed C-O bond cleavage. Since you can't ride a motorcycle year-round in the Midwest, Lily moved back to the best coast after earning her Ph.D., and joined the Toste lab as a postdoctoral researcher in 2018. Lily is interested in applying her background in homogeneous catalysis to heterogeneous systems for reductive amination processes.
