In this emotional and forward-thinking talk, Dr. Hossein Zargartalebi shares his deeply personal journey from a hospital room to a scientific breakthrough. His innovation—a molecular sensor that detects proteins in real time—may unlock a new era in healthcare, one where disease can be caught long before symptoms appear. By turning biology’s quietest signals into a clear voice, this technology gives us something medicine has never truly had before: the ability to act early, save lives, and give people back the most precious thing of all—time.

Dr. Hossein Zargartalebi is a biotech innovator and entrepreneur developing next-generation wearable and implantable biosensors that monitor protein biomarkers in real time, inside the body. His work enables continuous tracking of inflammation, diabetes, heart failure, and other chronic conditions — opening the door to earlier diagnosis, personalized treatment, and adaptive care.

He is an NSERC Postdoctoral Fellow at Northwestern University, where he works under the supervision of Prof. Shana Kelley. He began his postdoctoral research at the University of Toronto before transitioning to Northwestern to further expand his work in biosensor innovation. He earned his Ph.D. in Mechanical and Manufacturing Engineering from the University of Calgary, where he developed diagnostic tools for cancer and COVID-19.

Dr. Zargartalebi has received numerous awards for his research, which has been published in over 20 leading journals and featured in major media outlets.
