Bio and Interests

I am a Senior Researcher at the eXascale Infolab at the University of Fribourg, Switzerland. I received my Ph.D. in Electronics and Computer Engineering (ECE) from Hanyang University under the supervision of Prof. Yong Ho Song and Prof. Jinsub Park in 2022 in Seoul, South Korea. I also got my BSc in ECE at Hanyang University under Prof. Yong Ho Song in 2014 in Seoul, South Korea.

My research interests include computer storage systems, especially exploring architectures to deliver better performance from a host interface perspective.
