I obtained my PhD in Daniel Durocher lab at the Lunenfeld Institute of Mount Sinai Hospital, and Department of Molecular Genetics at the University of Toronto. With Dan I learned about using molecular biology, genetics, and cell biology to understand genome stability, DNA repair, and telomere biology. Meanwhile I graduated from a two-year radiation medicine program (EIRR21, now STARS21) in the Department of Radiation Oncology at University of Toronto and held a Certificate in Project Management from University of Toronto. With a CIHR fellowship and later a Mitacs Elevate Fellowship I further conducted postdoctoral work in the labs of Sachdev Sidhu and Jason Moffat in the Donnelly Centre at the University of Toronto. I learned from Dev and Jason how to “modulate” cell signalling using protein engineering, synthetic biology, and systems biology approaches. Here in my own lab, I propose to combine the expertise I gained from my PhD and Postdoc studies to further understand and modulate DNA damage responses for novel cancer therapeutics.

My research team creates synthetic probes modulating protein-protein interactions to: 1) accelerate understanding of biology, and 2) facilitate development of novel therapeutics. For example, we systematically generated inhibitors and activators for E3 ubiquitin ligases to discover new enzyme catalytic mechanism and new E3 substrates: Zhang et al. Molecular Cell 2016Gabrielsen et al. Molecular Cell 2017 We also create molecular tools to increase CRISPR-Cas9 genome-editing efficiency: Canny et al. Nature Biotechnology 2018 Finally, we showed that structure-based protein engineering enables development of anti-viral reagents for Middle East respiratory syndrome (MERS) coronavirus: Zhang et al. PLoS Pathogens 2017

Currently, we are interested in the following research projects:

  • Development of synthetic peptides and proteins to delineate biochemical mechanisms of E3 ubiquitin ligases
  • Engineering post-translational modifications to probe and rewire DNA damage signaling for cancer therapeutics
  • Improvement of CRISPR-based gene editing through directed evolution
