Paul Park is a fourth-year medical student at UCSF. He became interested in addressing health disparities as an undergraduate studying public health at UC Berkeley. His past experiences include working with the homeless population in the Bay Area, conducting a clean drinking water research project in Tanzania, and partaking in clinical research in TB, HIV and malaria. He became interested in surgery after his third-year clerkship at the San Francisco General Hospital and co-founded the GSSA chapter at UCSF as a way to incorporate his global health background into this new career interest. Since then, he has been working with the Center for Health Equity in Surgery and Anesthesia at UCSF on local and global surgery projects and took a research gap year to work with a non-profit organization called KidsOR to help build data collection and research capacity at partner hospitals in low- and middle-income countries.

Saad Sahi

Saad was born in Lahore, Pakistan and just a few months later his family started their decades long journey across continents for his father's work assignments. Growing up in Pakistan, Saudi Arabia, Italy, Holland, and Canada, Saad moved to the United States as a sophomore in high school. During his time in America, he has lived in Boston, New York City, Detroit, and now Austin, TX. All of these moves, and each seemingly more than the last, have continued to shape Saad's perspective on the world in which we live. Although he studied philosophy in college and later even had a brief stint in the fashion industry, it was a documentary film about the work of Doctors Without Borders that first inspired Saad to pursue a career in medicine. Since that initial screening, each chapter of his life has brought with it more insight into the world of global health. Over the last five years, while training as a general surgery resident, he grew to appreciate the role that surgeons can play in ensuring global health equity. Today, he is excited to embark on his own journey by committing to a career focused on safely delivering essential surgical care globally through the lens of design thinking.
