Junmo Lee

I am currently a Postdoctoral Researcher at Seoul National University. I received my Ph.D. in Electrical and Computer Engineering from Seoul National University under the supervision of Prof. Soo-Mook Moon, and I also earned my B.S. in Electrical and Computer Engineering from Seoul National University.

My research focuses on blockchain systems, with particular interests in Layer-1 and Layer-2 scalability, state growth, storage efficiency, databases, security, and trusted execution environments (TEE).
