I'm from the Great White North, born and raised in small town Canada, just outside Toronto. I studied Biology and Genetics at McMaster University and continued on to complete my Masters in Evolutionary Biology and Population Genetics. I loved the constant learning of academia but missed working on an individual to individual basis, and so I made the jump from the basic sciences into medicine. Through the Keith B. Taylor Global Scholars Program at St.George's University School of Medicine, my...

Mwelwa Chinzinga

Resident

Born into a family of farmers, I grew up in rural Sub-Saharan Africa. As a small boy, I learned the science and art of agriculture from my father. I have childhood memories of returning home at the end of a long day, soil-stained and satisfied. However, as I grew older, the satisfaction gained from working the land was no longer enough for me. In a country with a life expectancy of 57 years, there were profound problems that were part and parcel of my daily life—and I wanted to be part of...

I grew up in Cabimas, a small town where the oil bonanza started in Venezuela.

I was taught about love and compassion while providing comfort and support to the less fortunate. The more time I spent in medicine, the more I realized the essential and noble role doctors play in society.
