Professor, Pathology & Molecular Medicine

Expertise: MicrobiologyPathologyMolecular MedicineInfectious Disease

In 2009, she joined the Department of Pathology & Molecular Medicine at McMaster University and was promoted to associate professor in 2014. In 2019, she was promoted to tenure professor in the same department. The Bowdish lab focuses primarily on the effects of aging on the immune system, specifically macrophages. Her lab has been able to elucidate a mechanistic explanation for how aging alters myeloid cells and how these cells increase susceptibility to pneumococcal pneumonia. In 2017, the Bowdish lab demonstrated that age-associated gut microbe dysbiosis in mice increases age-associated inflammation. Bowdish currently holds an h-index score of 38. Bowdish's published works have received much media attention and continue to contribute more information regarding the interplay between the immune system, the gut microbiota, susceptibility to infection and aging.

"There are a significant proportion of people who are young, who still need major, major intensive care to get through this time and so even if, in general, younger people are okay, there will be some young people who will need major medical intervention to get through this and just because you're young, doesn't mean you're not passing it on."
