- Calcium and ROS interactions in healthy and diseased skeletal muscle
Research
My research focus is to quantify the levels and movements of calcium and reactive oxygen species (ROS) within the triadic microdomain and bridge the knowledge gap in calcium and ROS crosstalk.
At rest, these two processes must interact to maintain muscle at the ready for peak performance. However, we currently do not understand how ROS and calcium interact to maintain the system for optimal muscle contraction.
My research aims to determine how calcium, ROS, and their interaction can alter muscle function in health and disease, via regulation of triadic microdomain homeostasis. To achieve this, my lab uses several techniques, including live-cell confocal microscopy of mechanically skinned and intact muscle fibres, western blotting, viral transductions and electroporation.
