Professional Summary

Dr. Yaras works at the interface of optics, acoustics and electronics, developing sensors and transducers for biomedical applications. His current research focuses on development of catheter based intravascular sensors for image guided therapies with an ultimate goal of enabling more effective diagnostic and therapeutic procedures into clinical practice.

Background

Dr. Yaras is a Research Engineer in the G.W. Woodruff School of Mechanical Engineering, mainly working in the Micromachined Sensors and Transducers Lab. He received his PhD degree from Georgia Tech (2020), MS degree from Koç University (2016) and BS degree from Sabanci University (2013), all in Electrical Engineering. He held positions of postdoctoral fellow, graduate research assistant and visiting researcher at Georgia Tech since 2015. He developed a novel acousto-optic sensing platform enabling safer magnetic resonance imaging (MRI) procedures during his PhD. He was a predoctoral fellow in the Cardiovascular Intervention Lab at National Heart Lung and Blood Institute (NHLBI), National Health Institutes (NIH), in 2018. He also served as the Entrepreneur Lead in National Science Foundation (NSF) I-Corps Teams Program, where he investigated the commercial potential of the acousto-optic sensors in 2019. Prior to joining Georgia Tech, he developed a fiber-optic based point of care blood coagulation testing system at Koç University.
