M. Fatih Toy

Associate Professor and Head of Biomedical Engineering

Istanbul Medipol University

M. Fatih Toy is an associate professor at Istanbul Medipol University, where he heads the Department of Biomedical Engineering and leads the Phi-X lab, which he founded in 2015.

He received his PhD in photonics from EPFL in 2013, working on digital holographic microscopy in Christian Depeursinge’s group, including systems for imaging living cells under simulated microgravity and on parabolic flights. In 2013 he co-founded Nanolive SA, whose 3D Cell Explorer brought holotomography to life-science labs.

His awards include the Turkish Academy of Sciences Outstanding Young Scientist Award (TÜBA GEBİP, 2021) and JCI’s Ten Outstanding Young Persons of Turkey (2017).
