He is currently an Emeritus Research Fellow at the Center for Underground Physics of the Institute for Basic Science in Korea. His research has concentrated mostly on studies of heavy quarks and their associated hadrons using CLEO at Cornell, AMY and Belle experiments at KEK in Japan, and the BES experiments at IHEP in Beijing. He currently participates in the KIMS dark matter and AMoRE neutrinoless double beta decay searches at the Yangyang Underground Laboratory in Korea. Olsen was an Alfred P. Sloan Fellow (1972-1977), a John Simon Guggenheim Fellow (1986-1987), a Japan Society for the Promotion of Science Fellow (1987-1988).
