Personal profile


My research is focused on developing a "designer" stem cell therapy for stroke using a non-human primate model. Our approach combines cell therapy with gene therapy to create designer cells for transplantation. Specifically, my work involves genetically engineering stem cells to ensure their safety and enhance their therapeutic function. We hope this research will accelerate the translation of cell therapies into human clinical trials.


I also have a long-standing interest in understanding the intrinsic and extrinsic factors that govern cell fate. In particular, I am interested in understanding how stem cells are regulated and behave in various native and artificially induced states of pluripotency. My previous work with Wnt/beta-catenin signaling sparked this interest, since Wnt signaling can act as both a positive or negative regulator of stem cell self-renewal, depending on the pluripotent state. Greater knowledge of the process of cell state change may enable us to generate alternative cell types with therapeutic relevance.
