My name is Inna Gertsenshteyn (EE-nah  GURTZ-en-shtine). I am a postdoctoral fellow at the Gordon Center for Medical Imaging at Massachusetts General Hospital and Harvard Medical School.

I received my Ph.D. in Medical Physics from the University of Chicago in 2022. My research focused on multi-modal imaging of tumor hypoxia to improve radiation therapy with Drs. Howard Halpern and Chin-Tu Chen.

I received my B.A. in Physics from Boston University in 2015.
Before starting graduate school in 2017, I worked as an Image Analyst at Invicro, a global research partner to pharmaceutical, biotech, and contract research organizations, aiming to enhance drug discovery and development. In early 2022 I did a co-op at Biogen in Late Discovery Imaging to gain industry experience.

My general research interests are in anything to do with multimodal imaging and image analysis. Outside of academia, I enjoy hosting house concerts, coffee dates with friends, going on walks, watching films, and reading.
