Research/Teaching

Research Synopsis

I seek to further the understanding of sudden, unexpected deaths that remain medically unexplained following a thorough death investigation. Specifically, I am seeking to explore the relationship between genetic changes in genes associated with cardiomyopathies and channelopathies in infants and those who die of Sudden Unexpected Death in Epilepsy (SUDEP).

Additional research endeavors are targeted towards leveraging the postmortem imaging capacity at the Provincial Forensic Pathology Unit in order to study how this technology can best be used in a reliable manner to assist with the medicolegal investigation of death.
