Personal Statement

Dr. Kunmo Koo is a Research Associate at the Northwestern University Atomic and Nanoscale Characterization Experimental (NUANCE) Center. He received a B.S and Ph.D. in materials science and engineering at Korea Advanced Institute of Science and Technology (KAIST). After graduation, he joined the Korea Research Institute of Standards and Science (KRISS) as a post-doc researcher and later joined the Electron Probe Instrumentation Center (EPIC) at NUANCE. With more than 10 years of extensive experience in transmission electron microscopy and microelectromechanical systems, he has specialties in developing in situ environmental microscopy techniques.
