Website Management Sub-Chair

Casey Patnode
University of Michigan Medical School

Casey dual-degree MD/MPH student at the University of Michigan. Prior to medical school, Casey earned his B.S.E. in Biomedical Engineering from the University of Michigan. During medical school, he realized that climate change is the largest public health crisis of the 21st century and it will disproportionately affect marginalized communities who have contributed the least to causing it. This resulted in him becoming impassioned in becoming involved in mitigation of climate change and adaptation to minimize its impact. To this end, he has done a sustainability fellowship on municipalities equitably reaching net zero emissions, work on integrating climate health into his medical school’s operations, and received the Healthcare Without Harm Emerging Physician Leader Award to facilitate improving the care of heat illness in the Emergency Department. He hopes to be a voice in rallying the public to address climate change as the health and equity crisis that it is.

Interest Group Liaisons

Plant-Based Health

Zachary Burns, DO, MPH
Brown Family Medicine Residency

Ocean Health

Kelly Williamson
Herbert Wertheim College of Medicine

Zach Burns trains at the Brown Family Medicine Residency. A plant-based nutrition advocate, he practices medicine to help improve the lives of human and non-human beings. Zach founded the organization Plant-based Healthcare in medical school at Nova Southeastern University to engage classmates in vegucation and advocacy around plant-based eating patterns. His reach extends nationally via Moving Medicine Forward, a non-profit dedicated to cultivating a generation of nutritionally literate physicians who are prepared to tackle our chronic disease burden. He pursued similar work on the Development team with the American College of Lifestyle Medicine Trainees. Zach was grateful for Harleen’s support in establishing the Plant-based Health Liaison position for MS4SF to highlight the urgency in transitioning to a plant-based global food system both for climate change mitigation and to combat deforestation, antibiotic resistance, and zoonotic infectious disease. He considers the problem of 200 million land animals killed per day within the purview of physicians striving to “do no harm.” Zach supports universal healthcare as an adjunct to improved nutrition policy and in medical school helped launch a chapter of Students for a National Health Program. His dream career includes family medicine at a community health center with designated time to engage in various facets of the movement to eradicate factory farming. He swears he is more fun in person and enjoys soccer and jazz piano.

Kelly Williamson is a second-year medical student at Herbert Wertheim College of Medicine in Miami, FL. Having spent her life living in Florida she has personally experienced how climate change has affected our oceans from living through extreme weather events to coastal flooding and rising sea temperatures. In recognizing the boundlessness of water, Kelly is interested in how water unites the health of our human family with all creation.
