Sangyeop Lee

University of Pittsburgh
Ph.D., Mechanical Engineering, Massachusetts Institute of Technology, 2015

Sangyeop Lee received his B.S and M.S. in Mechanical and Aerospace Engineering from the Korea Advanced Institute of Science and Technology (KAIST). He had obtained a scholarship for full tuition and boarding from the Korean government for both the B.S. and M.S. programs. Upon graduation he worked for nearly five years as a Research Scientist at KAIST. He then pursued and obtained his Ph.D. in Mechanical Engineering from the Massachusetts Institute of Technology with a Samsung scholarship. He finally joined the Department of Mechanical Engineering & Materials Science of the University of Pittsburgh in the fall of 2015.
