A. Chizari PhD (Ata)


About Me

Ata Chizari was born in 1990 in Tehran, Iran. He received his BSc (hons) in Electronics in 2013 from Tafresh university, Tafresh, Iran, and his MSc (hons) in Communication Systems in 2015 from Shahid Beheshti University, Tehran, Iran. From 2014 till 2016 he served as a visitor research assistant at Optical Networks Research Lab, Sharif University of Technology, Tehran, Iran, where he contributed to Optical Wireless Communications and Photonics research topics. He received his PhD in 2021 from the University of Twente, Enschede, The Netherlands where he serves as a postdoctoral researcher at the Biomedical Photonic Imaging. His research interests include laser speckle contrast imaging, laser Doppler perfusion imaging and speckle metrology.
