Inna Gertsenshteyn
My name is Inna Gertsenshteyn (EE-nah  GURTZ-en-shtine), and I'm a 4th year PhD candidate in Medical Physics at the University of Chicago. My co-advisors are Dr. Howard Halpern and Dr. Chin-Tu Chen. We are working on multimodal tumor hypoxia imaging with [18]F-MISO PET, EPR, and DCE-MRI to improve radiation therapy.

Before graduate school 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.

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 movies, and reading books.
