Research Interests

My research focuses on the interplay of HIV-associated chronic inflammation, immune activation, and accelerated aging. The risk of having medical conditions that are more frequently found in the elderly, such as heart disease, stroke, osteoporosis and dementia may relate to the premature aging of the immune system. I am currently conducting two large clinical studies of healthy Canadians and those with HIV to define the biological age of individuals as opposed to numerical age. Understanding immune parameters related to biological age may provide insight on why coronary artery disease may occur earlier in those with chronic inflammatory diseases.
