Dr. Matthew Triolo is a Postdoctoral Fellow working within Dr. Mireille Khacho’s lab in the Faculty of Medicine at the University of Ottawa. Matthew first completed his BSc in Kinesiology and Health Science with a Minor in Biology at York University. After completing his MSc investigating whether electrical pulse stimulation can enhance muscle cell activity under the guidance of Dr. Michael Connor, he subsequently worked towards his PhD as a member of the Muscle Health Research Centre at York University. While under the supervision of Dr. David Hood, his work focused on skeletal muscle autophagy, mitophagy and lysosome biogenesis in the context of aging, disuse, and exercise. As a new Postdoctoral Fellow, Dr. Triolo is investigating mechanisms by which mitochondria regulate muscle stem cell homeostasis and function. He enjoys playing a variety of sports including hockey, golf and baseball, and spending time with his family, friends, and cat, Luna.
