Education Ambassadors

Our ambassadors are a group of researchers, MDs, and scientists who are former participants in our courses and training programs. In addition to the expertise and knowledge they bring to their respective specialties, they share a passion for the training and other resources we provide.


Headshot of Hamed Khachan. Hamed Khachan, MD MPH, is a clinician-scientist who is passionate about public health, policy, management, health tech, and patient-centered design. He currently works as a clinical research associate at the health technology company ICON where he oversees several clinical trials. He is a dual-certified instructor of youth and adult mental health first aid who leads these courses in collaboration with Cambridge Health Alliance in his local community. His work aims to alleviate healthcare disparities by working with data and research in diverse and underserved populations. He attended medical school in Bangladesh and has practiced medicine in Libya, his country of birth.

Previous Ambassadors

Dayo Fadelu, MD, MPH, is an instructor in medicine at Harvard Medical School, member of the Center for Global Cancer Medicine (CGCM), and oncologist in the Department of Medical Oncology at Dana-Farber Cancer Institute (DFCI). His clinical and research interests are breast cancer, health services research, and global oncology implementation. His research at the Center for Global Cancer Medicine is focused on breast cancer care delivery in Rwanda and Haiti. He utilizes a mixed-methods approach to uncover the causes of poor treatment completion rates in breast cancer patients undergoing curative intent therapy, and designs context-appropriate interventions. Fadelu completed his fellowship training in medical oncology at DFCI and obtained his master’s degree in public health at the Harvard T.H. Chan School of Public Health.

Sudeshna Fisch, PhD, is the associate director of a busy and prolific preclinical core (Cardiovascular Physiology, Department of Medicine, Brigham and Women’s Hospital). Additionally, she serves as guest editor and reviewer for scientific journals, and seeks new collaborations and learning opportunities. Fisch’s research focuses on preclinical therapeutic studies using mouse, rat, and zebrafish models (surgical and non-surgical techniques including advanced cardiac imaging and data analytics). Her prior work includes intellectual property (IP), and research commercialization and grant-funding strategies, with stints at The Broad Institute (chemical biology), Nanobiosym (nanotechnology), Harvard’s Office of Technology Development, Partners office for Research Ventures and Licensing, and Fish & Richardson, LLP.  She was born in Calcutta, India, and earned her BS and MS degrees in zoology and genetics from Calcutta University, where she received a National Merit Scholarship award. Fisch received her PhD in biological sciences on a full scholarship from Bowling Green State University in Ohio before moving to HMS for postdoctoral work.

Junaid Nabi, MD, MPH, is a public health researcher and medical journalist. A senior researcher at Harvard Business School, he is examining how value-based healthcare strategy can transform care delivery and promote health equity. He is also a senior fellow at the Aspen Institute and a fellow at the Harvard Graduate School Leadership Incubator. His previous projects at Harvard Medical School and Brigham and Women’s Hospital included investigating health system factors that lead to racial disparities in cancer care, evaluating the economic impact of innovative medical technologies, and implementation of novel digital decision support tools into electronic medical records. His ongoing research in medical ethics and global health policy includes studying global health colonialism and healthcare equity, understanding the role of bioethics in artificial intelligence-based medical decision-making systems, and applying principles of behavioral economics in the delivery of healthcare. In 2020, he served as an emerging leaders fellow at the United Nations Association of the United States and coordinated one of the first global lectures on systems-based public health response to the COVID pandemic.

Samira Musah, PhD, is a stem cell biologist and a bioengineer trained at the interface of chemistry, biology, and engineering. She holds a joint faculty position at Duke University in the biomedical engineering and medicine departments. In addition to being a Duke MEDx (Medicine and Engineering Interface) investigator, she is an affiliated faculty of Duke Regeneration Next initiative. Her laboratory’s research covers a range of interests from fundamental studies of stem cell and tissue differentiation to engineered microphysiological systems for disease modeling, diagnostics, and therapeutics. Her lab seeks to advance the understanding and treatment of kidney disease. Musah completed her postdoctoral fellowship at Harvard University, and her PhD from the University of Wisconsin-Madison.

Vicky Bai, PhD, is associate medical director of clinical science at Takeda, where she helps bring novel therapeutics to patients with cancer to improve their health via science-driven clinical trials. Previously, Bai was a clinical research scientist at Karyopharm Therapeutics, instructor at Harvard Medical School, and a senior clinical research scientist/project manager at Brigham and Women’s Hospital. Bai completed her postdoctoral research training at Harvard Medical School and Brigham and Women’s Hospital. She received her PhD in pharmacology from University of Texas Health Science Center at San Antonio, her master’s in medical science from Peking University Health Science Center, and bachelor’s in medicine from Qingdao University Medical College.
