Tsui Research Group

We are looking for enthusiastic graduate students and undergraduates! Opportunities may also be available for interested postdoctoral researchers. Please contact Emily.

Research in the Tsui group will focus on the development of new catalysts using principles and techniques from the areas of bioinorganic, organometallic, and nanomaterials chemistry. Biological enzymes and heterogeneous catalysts are capable of activating very strong bonds in small molecules with high activity and specificity. We will design transition metal complexes and nanoscale materials as models of these systems, incorporating new structural or compositional motifs from enzymatic or heterogeneous active sites to enhance the performance of our artificial catalytic systems. An improved fundamental understanding of these systems will have important applications in chemical synthesis, liquid fuels production, and energy storage.

Emily Y. Tsui

Emily was born in Maryland and received her B.S. degree from the Massachusetts Institute of Technology in 2008. She received her PhD in 2014 from the California Institute of Technology, where she worked in the labs of Prof. Theodor Agapie studying the synthesis of multimetallic complexes as models of biological active sites. From 2014-2017, Emily was a NIH postdoctoral fellow with Prof. Daniel R. Gamelin at the University of Washington studying surface redox reactivity of semiconductor nanocrystals. She will join the University of Notre Dame Department of Chemistry & Biochemistry in the summer of 2017.
