Biography

He received the B.Sc. degree in Electrical Engineering-Electronics from University of Kurdistan, Kurdistan, Iran, in 2010, and the M.S. degree in Microelectronic Circuits from Sharif University of Technology, Tehran, Iran, in 2012. He is currently pursuing the Ph.D. degree with the Smart Biomedical Microsystems Lab, Université Laval, Quebec, Canada. His main research interests include wireless biomedical systems, optoelectronic, data converters, and analog/mixed-signal designs.

Project : Fully integrated spectrophotometer in the Visible and Near-IR Range

This project aims to develop a wireless microsystem for performing diffuse multi-wavelength spectroscopy in real time monitoring of extracellular neurotransmitter concentration or protein interactions based on fluorescent sensing principles. The envisioned system-on-chip has combined integrated metal patterns implementing nanoplasmonic filters and microelectronics on the same chip to have an unprecedented level of miniaturization for a photospectrometer. Using CMOS technology allows decreasing the power and size dramatically and to increasing the area of applications toward a point-of-care setup. New circuit techniques are leveraged to decrease the input referred noise without increasing the size and power consumption, enabling the utilization of a small battery as an energy source.
