Dr. Yoonsu Choi

Dr. Choi worked at Korea Telecom Research Center as a research engineer between 1995 and 1999, where he led the design and development of a network data communication. Dr. Choi received Ph.D. degree from the School of Electrical and Computer Engineering at the Georgia Institute of Technology in 2005 with a title “A Three dimensional Coupled Microelectrode and Microfluidic Array for Neural Interfacing”. After he finished his PhD project with biomedical applications, he went deep into the biological area to make the solid interdisciplinary research background. While he worked at the University of Texas MD Anderson Cancer Center as a research engineer for four years, he was awarded the Leukemia and Lymphoma Society career development grant. Coming back to the original PhD work of neuroscience research, he was a research faculty in the Department of Biomedical Engineering at the Georgia Institute of Technology in 2010. Since then, he has been working on a regenerative peripheral nerve interface system as his second interdisciplinary research along with cancer research. In 2013, he joined in the Department of Electrical Engineering at UTRGV as an assistant professor and has continued his neuroscience and cancer research. He became a tenured associate professor in 2017. His research interests include Neural interfaces, Cancer, and MEMS.

  • Areas of Expertise

    • Dr. Choi’s research interest focuses on two frontiers of neuroscience: 1) the development of the single neuron peripheral nerve interface system, and 2) the mapping of animal behavioral patterns with global neural network data throughout both the central and the peripheral nervous systems (CNS-PNS). This is attainable using a three-level single neuron network that consists of a single neuron peripheral nerve interface (SNI) placed on the peripheral nervous system and custom-designed µCuff/µECoG interfaces on the central nervous system. The SNI isolates individual axons and communicates with them. It gives us the capability of both electrophysiological recording and stimulation to complete a single neuron network (SNN) from the brain to the endings of peripheral nerves.
