Harvard–MIT Program in Health Sciences and Technology (Yiyin) Erin Chen is an American immunologist, microbiologist, and dermatologist.
She then completed her MD-PhD training through the Harvard-MIT Health Sciences and Technology program, receiving her PhD from MIT in 2011 and her MD from Harvard Medical School in 2013.
They employs microbial genetics, immunological approaches, and mouse models to study how commensal skin bacteria communicate with and educate the immune system.
[6][7][8]A key area of Chen's work involves developing genetic engineering methods for commensal skin bacteria.
In 2023, Chen and colleagues demonstrated that engineered skin bacteria could induce antitumor T cell responses against melanoma in mice.
