The research interests in my lab are in the field of ubiquitin signaling, protein engineering, targeted protein degradation, genome stability, and cancer therapeutics. In the past several years, my lab has been working on development of synthetic biology approaches to manipulate human cell signal transduction cascades to identify new molecular mechanisms and innovative therapeutic strategies. Since July 2018, when we started the independent lab at University of Guelph, we have published 20 papers in high impact journals.
We greatly appreciate the following agencies currently providing funding support to this laboratory: Canadian Institutes of Health Research (CIHR), Natural Sciences and Engineering Research Council of Canada (NSERC), Canadian Foundation for Innovation (CFI), and the Early Researcher Awards program funded by the Ontario Ministry of Colleges & Universities.

In the Zhang lab, we create 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 2016; Gabrielsen 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. Please check here for the complete list of publications.
Currently, we are interested in the following research projects:
Developing synthetic proteins to manipulate ubiquitin signaling for cancer therapeutics
Engineering protein-protein interactions to probe and rewire DNA damage reponse
Creating new molecules to recruit E3 ligases for targeted protein degradation
