Biography

Gokhan is currently an Associate Professor, the chair of the Biomedical Engineering Department, the deputy chair of the Non-Interventional Clinical Research Ethics Board, and the board member of the Ethics Committee for Clinical Research at Yeditepe University.

Gokhan received his PhD and MSc degrees in Biomedical Engineering both from the Institute of Biomedical Engineering, Bogazici University, Turkey, in 2007 (as top-ranked), and BS degree in Electronics Engineering from Erciyes University, Turkey in 1999.

At Yeditepe University, Gokhan focuses his attention on developing smart home healthcare devices, assistive mobility devices and wearable devices for physiological activity monitoring and recognition. He also leads the efforts in developing deep learning models for accurate diagnosis of prostate cancer from MR images. Gokhan instructs many courses such as “Medical Informatics”, “Rehabilitation Engineering”, “Biomedical Instrumentation” and “Medical Imaging” and works on improving biomedical engineering education in Turkey.

Gokhan has been the researcher, and consultant for many European Union or TUBITAK granted research projects. He has been in collaboration with colleagues from Marmara University, Istanbul University, Acibadem University and Koç University and published many conference and journal papers.

Gokhan previously worked as a researcher at The Institute of Cancer Research UK (as top-ranked) and The Royal Marsden Hospital in between 2007-2010. He managed research in developing computational methods to comparing breast MR images, joint with University of Oxford, University of Manchester and University College London.

During his graduate study at Bogazici University, Gokhan was the researcher in projects with a goal of developing novel image computing algorithms to diagnosing breast cancer using X-ray imaging and MR Imaging. In 2006, he developed “DynaMammoAnalyst”, an interactive dynamic analysis and decision support software for contrast-enhanced breast MR imaging.
