Biography

Dr. Khacho joined the Faculty of Medicine at the University of Ottawa as an Assistant Professor in the Department of Biochemistry, Microbiology and Immunology in January 2018. She is the Canada Research Chair tier2 in Mitochondrial Dynamics and Regenerative Medicine. She is also a member of the University of Ottawa Neuromuscular disease center and the Ottawa Institute of Systems Biology (OISB). Dr. Khacho has made significant contributions to our current understanding of the role of mitochondrial shape in stem cell function and longevity. Her work revealed the molecular mechanisms of how mitochondrial shape can direct the fate of stem cells and promote differentiation. As a postdoctoral fellow with Dr. Ruth Slack, a notable leader in neurobiology, Dr. Khacho made theĀ pioneering discovery that mitochondria are upstream signaling centers that dictate stem cell fate. This work has far reaching implications in aging and regenerative medicine and has now established a new area of research that bridges mitochondrial/metabolic regulation with aging and degenerative disease and stem cell function.Ā Dr. Khachoā€™s research is focused on understanding key mitochondrial signaling pathways that are crucial for stem cell maintenance during aging and degenerative diseases.Ā The discovery and characterization of these pathways would pave the way towards advancing stem cell therapies.
