Bio and Expertise

Bio
Dr. Melikhan Tanyeri received his B.S. degree from Bogazici University in 1999, and his Ph.D. degree from University of California, Davis in 2006. During 2006-2012, he worked as a postdoctoral researcher with Prof. Charles Schroeder at the University of Illinois at Urbana-Champaign. Between 2013-2016, he was an assistant professor in the Department of Electrical and Electronic Engineering at Istanbul Sehir University. After a brief research scientist position at University of Chicago, he joined Department of Engineering as an assistant professor of biomedical engineering.

His research interests include microfluidics, chemical and biomolecular sensors, and high-resolution imaging. His research accomplishments include the first demonstration of lasing spherical microdroplets in a microfabricated device. He developed chemical and biological sensor platforms based on micro and nanoscale optofluidic systems. More recently, he established a new class of microfluidic tools for single particle and cell manipulation towards applications in nano- and biotechnology.

Research

We employ micro and nanoscale tools/systems and state-of-the-art optical microscopy techniques towards challenges in biosensors, point-of-care diagnostics, and mechanics & dynamics of biomolecules and cells. My current research group has extensive background in microfabrication, micropatterning, soft lithography microfluidics, brightfield, fluorescence and superresolution microscopy, cell-material interactions, and development & applications of novel sensors and actuators. We design and implement methods, assays, and devices at the micro- and nanoscale for highly sensitive detection, confinement, and manipulation of molecules and cells. Below, I provide a few examples of projects that we are currently pursuing:

• Portable blood coagulation analysis systems
• Microfluidic trapping, manipulation and separation of biomolecules and cells
• High throughput analysis of single cell behavior
• Early detection of bacteria
• Microfluidic platforms for studying single cell mechanotransduction

Overall, we pursue a multidisciplinary, applied research program in developing optofluidic tools and techniques to address current challenges in bio/nanotechnology.

Teaching

I embrace the "educate, inspire, engage" approach. My overall objective in teaching and advising (mentoring) is to foster a positive learning environment in order to engage students in acquiring, testing and generating knowledge, and to attain skills indispensable for establishing themselves as distinguished individuals of the next generation of engineers. I envision my role as a teacher/mentor to motivate students by curbing their enthusiasm and stimulating their interest; and eventually empower them to think creatively and independently.

I teach the following courses under our undergraduate and graduate programs in Biomedical Engineering:

BMED 110 Introduction to Programming for Engineers
BMED 310 Biomedical Signals and Systems
BMED 451/551 Biomedical Microdevices I
BMED 452/552 Biomedical Microdevices II
