Student Ambassadors 

Eirliani Abdul Rahman

Doctoral Student of Public Health

Eirliani Abdul Rahman (aka “Lin”) is a final-year student in the doctoral program in public health (DrPH). She would like to leverage the C-CHANGE program to bring attention to climate change as an important risk factor for human trafficking. Her diplomatic experience, having served in the Singapore Foreign Service, coupled with working for the Nobel Peace laureate Kailash Satyarthi, gives her a unique perspective on public health challenges, especially the link between human trafficking and poor health. A Fellow of the Royal Society for the Arts, she loves exploring the Arctic and trained with renowned polar explorers Matty McNair and Sarah McNair-Landry over two winters in Nunavut, Arctic Canada. Lin plans to ski the last degree to the North Pole post-graduation to raise awareness on child sexual abuse, being a survivor herself.


Amr Al-Absi

Masters Student in Nutrition

Amr Al-Absi is a first-year MPH student in nutrition and an International Students Advocate at Harvard Chan. He is interested in the connections between climate and health in particular because as an MPH student, he knows that climate change can adversely affect human health by intensifying existing health issues, facilitating the spread of diseases, and increasing the frequency and severity of extreme weather events, thereby posing considerable threats to global public health. As a Harvard Chan C-CHANGE Student Ambassador, Amr hopes to deepen his understanding of climate change and its intersection with public health, engage in meaningful advocacy and outreach activities, and contribute to fostering awareness and sustainable solutions within the community.

Rebecca Bromley-Dulfano

Doctoral Student in Health Policy

Rebecca Bromley-Dulfano is a second-year student in the Health Policy PhD program at Harvard and fourth year medical student at Stanford School of Medicine. Her interests in climate and health include empowering medical and public health professionals to support patients through climate shocks such as wildfires, floods, and heat waves, and improving the sustainability of clinical practice in the US. She is one of the co-founders and former directors of Stanford Climate and Health, a student-led group formed around projects spanning across the many intersections of climate change and health. Through SCH, she co-founded and helped organize the annual NorCal Symposium on Climate, Health and Equity (first held in 2020), to bring together major academic medical institutions and community partners across the Bay Area to take local climate action. Her previous research has focused on the comparative sustainability of reusable PPE over single-use disposables in healthcare settings. During her time in medical school, she also partnered with the Santa Clara County Public Health Department to help support the development of a climate health equity and vulnerability assessment for the county, and with the Santa Clara County Office of Sustainability to develop a county-wide ecosystem map of the community based organizations working on community climate resilience.
