Welcome to the Gillis Lab. This lab, led by Dr. Todd Gillis, is focused on the vertebrate heart and the mechanisms that regulate it’s function and ability to remodel in response to a physiological stressor. Ongoing projects include:
- Examining cardiac remodeling in zebrafish and trout in response to thermal acclimation
- Characterizing the role of the troponin complex in regulating the function of striated muscle
- Examining the function of the hagfish heart during prolonged anoxia exposure
- Examining the change in diaphragm function during the onset of heart failure
- Characterizing how bitumen exposure of sockeye salmon early life stages influences cardiac development and aerobic fitness.
We use a number of approaches in these studies that integrate functional experiments with molecular and proteomic tools to examine gene and protein expression/phosphorylation. This integration provides insight into the cellular mechanisms that underpin identified functional changes.
There are currently positions in the lab for 2 PhD students in the lab. These are detailed in the “Opportunities” page. Please explore our current work via the “Research page” and then contact Dr. Gillis via email regarding your interests.
