A Short Bio

I was born in Daegu, South Korea, in 1990. After graduating from Korean Minjok Leadership Academy (KMLA), a small school in the middle of the mountains of Gangwon Province, South Korea, I moved to New York City to enjoy the hustle and bustle of the city life. I went to The Cooper Union to study Electrical Engineering. From Summer '12 and until I moved from the city, I had worked for Columbia University's EnHANTs project group, with Prof. Gil Zussman's wim.net lab and Prof. John Kymissis's CLUE.

After graduating from The Cooper Union, I decided to shift the gear of my life once again. I went to Ann Arbor, MI, a small and calm city in the Midwest, for my postgraduate studies. There, I worked with Prof. Yoon, focusing on development of implantable multi-electrode arrays (a.k.a. neural probes) with multiple functionalities such as optogenetics for a variety of in vivo, freely behaving animal experiments. I received an M.S.E. degree in Electrical Engineering in 2015, and defended my PhD dissertation in 2019.

Currently, for my military duties, I am working at KIST, in Seoul, South Korea, as a research scientist. Here, as a member of the Center for BioMicrosystems, Brain Science Institute, I am working with teams of neuroscientists and engineers from a number of different backgrounds to develop groundbreaking tools for neuroscience research and neurotherapeutics.

Projects

A have worked on several interesting engineering projects. Here I am listing only a few of them.

Neural probes with monolithically integrated μLEDs for optogenetics in freely behaving animals

For my PhD thesis, I developed neural probes that have monolithically integrated neuron-sized micro-LEDs that can be used in studies of brain circuits in feely behaving animals with the highest spatial and temporal resolution known to date.

A system for closed-loop neuroscience experiments in moving animals

During '16 - '17, I worked with Adam Mendrela to develop a neural recording and stimulation system with a miniature 'headstage,' using the μLED optoelectrode. I am expecting the system to help neuroscientists run a number of exciting neuroscience experiments that take advantage of its capability to interact with brain circuits in closed-loop.

Dissemination of new tools for brain circuit mapping

Since Fall '17 and until I left UM, I worked with a team of engineers to provide neuroscientists around the world with novel tools for brain research. I managed processes of fabrication, assembly, and chracterization of the μLED optoelectrodes. The devices are being disseminated through NeuroNex MINT, an NSF-funded neurotechnology hub.
