John Chik

Dr. John Chik's interest in questions that lie at the intersection of biology, chemistry and physics was planted when, as a graduate student, he became fascinated by the mystery of how living organisms exploit ATP (adenosine triphosphate) hydrolysis to generate mechanical work, as exemplified by muscle contraction. Through an adjunct-assistant professorship at the University of Calgary, he is continuing muscle-related research by co-supervising a MSc student project using the novel method of hydrogen/deuterium exchange mass spectrometry to study calmodulin-mediated, calcium activation of smooth muscle contraction, and an undergraduate summer student project examining the mechanism behind smooth muscle myosin activation by light-chain phosphorylation. Funded by MRU, Dr. Chik has also initiated research exploiting the novel properties of "heavy water" to investigate "water-mediated" force, such as the hydrophobicity and hydration forces, and how they influence protein structure and function. In addition to furthering our understanding of the life-critical properties of water, this research will have practical implications for improving protein stability which, for example, would be of interest in the area of vaccine storage.
