Celebrating the 2023 Emerging Physician Leader Award and Sadler Fellowship recipients

The Emerging Physician Leader Award

The Emerging Physician Leader Award, established by the Health Care Without Harm Physician Network in 2018, recognizes medical students, residents, and fellows who have demonstrated a passion for sustainable health care or a commitment to climate and health leadership. Awardees receive complimentary registration to CleanMed and a grant to support a project that aligns with the goals of the Physician Network. This year, the award is offered in collaboration with the Association of American Medical Colleges.

Join us in celebrating this year’s Emerging Physician Leader awardees chosen from a large, exceptionally strong, and talented applicant pool.

Tina Bharani

Tina Bharani, M.D., a general surgery resident at Thomas Jefferson University Hospital, was selected for her varied academic interests including surgical nutrition, climate-friendly diets in health care, value-based health care, and sustainable health care, especially minimizing surgical waste. For her project, she will identify unused instruments in surgical trays and evaluate inter-surgeon variability related to surgical instruments for three commonly performed laparoscopic abdominal procedures: cholecystectomy, hernia repair, and sleeve gastrectomy.

“I am deeply honored to receive the award because this opportunity will help me build lasting connections with leaders in the field whose wisdom and guidance will be instrumental in my future efforts. I am most excited to attend CleanMed because I will get to learn about the challenges that leaders in the field have faced in promoting environmental sustainability in medicine first-hand. This will provide me with invaluable lessons to tackle the challenges that I will face in my journey.”

Tina Bharani, M.D.

Taylor Diedrich

Taylor Diedrich, a medical student at Indiana University School of Medicine, was selected for her leadership role as the co-director of the Planetary Health Report Card, efforts to integrate planetary health education into the medical school curriculum, and interests in climate-smart health care and low-emissions inhalers. For her project, she will implement climate-smart inhaler practices at a pediatric clinic.

“Receiving this award is an absolute honor, and I am looking forward to connecting with other leaders in sustainable health care at CleanMed this year. The operating room is a major source of both waste and greenhouse gas emissions with many opportunities for improvement. I plan to focus my career on reducing the environmental impact of surgery, and the support from Health Care Without Harm is instrumental as I work toward this goal.”

— Gwyneth Sullivan, M.D., M.S.

Emily Yamron

Emily Yamron is a medical student at Albert Einstein College of Medicine. She was selected for her interest in the link between extreme heat and cardiac disease and leadership as a medical student, including her roles on the executive board of the Einstein Sustainability Club and as curriculum co-chair of Medical Students for a Sustainable Future, and for her recognition that creating resilience to extreme heat is a climate justice issue.

For her project, she will create educational resources about the intersection between heat, health, and health care with a goal of mitigating health disparities and creating climate resilience among vulnerable groups in the Bronx community who face a disproportionate burden of disease due to extreme heat events.

2023 Blair and Georgia Sadler Fellows

The Blair and Georgia Sadler Fellowship, established in 2022, provides an opportunity for a cohort of early-career clinicians to work together on equitable, climate-smart health care in their hospitals and communities with the support of subject matter experts and Health Care Without Harm and Practice Greenhealth partner health systems. Each year, fellows receive a scholarship to attend CleanMed and a $1,000 grant to complete a project that aims to demonstrate scalable solutions.

Join us in celebrating this year’s Blair and Georgia Sadler Fellowship awardees chosen from a large, exceptionally strong, and talented applicant pool.

Divyansh Agarwal

Divyansh Agarwal, M.D., Ph.D., is a general surgery resident at Massachusetts General Hospital and a postdoctoral affiliate at Massachusetts Institute of Technology. He was selected for his academic interests in reducing the environmental impact of surgical care, and in addressing diversity, equity, inclusion, and belonging and its intersection with climate and health care.

For his project, he will lead an initiative to replace single-use disposable scrub caps with reusable cloth caps embroidered with surgical staff members’ names, credentials, and roles, with a goal to reduce waste and emissions, and to reduce misidentification of health professionals, usually women and people of color due to systemic biases.

“I am thrilled to connect with like-minded peers as well as mentors, who can advise me as I seek to merge sustainability efforts in my future career as a surgeon-scientist. Integration of climate and planetary health in the decisions we make in the operating room remains poorly studied and often neglected. I look forward most to bringing first-hand knowledge back with me that can help me address this gap during my residency training and beyond.”

— Divyansh Agarwal, M.D., Ph.D.

Channing Hou

Channing Hou, a medical student at Lewis Katz School of Medicine at Temple University, was selected for his passion for creating a more equitable and sustainable health care sector and commitment to advocating for systemic changes to create health resilience in disadvantaged communities, including the community surrounding his medical school, which is disproportionately impacted by I climate and toxic exposures.

For his project, he will calculate cost, waste, and emissions reductions from optimizing cataract surgical trays by reducing unused instruments from the trays.

“I am incredibly honored to receive this award. As a medical trainee, I was shocked to see how much waste was generated by surgical cases, and I am fortunate that Health Care Without Harm has given me the tools to create change.
