# Vasiliki Demas

> Vasiliki 'Vicky' Demas, PhD, is the CEO and founder of identifeye HEALTH, an AI-enabled retinal imaging company that brings specialized eye screening to primary care settings. A chemical engineer by training with a PhD from UC Berkeley and a postdoc at Lawrence Berkeley National Lab, she cut her teeth as a founding member of Google Life Sciences (which became Verily) and helped build foundational technology for GRAIL's Galleri multi-cancer early detection test. At identifeye HEALTH — which she joined in 2021 and rebranded from Tesseract Health — she leads a 38-person team developing a portable, FDA-registered AI retinal camera that lets minimally trained staff detect diabetic retinopathy and systemic disease markers in the same visit patients already make to their primary care doctor.
