Biography
Dr. Kohei Kume completed his PhD at Iwate University (Morioka, Japan) in 2011 with mentorship from Yasushi Saitoh, PhD. After a postdoctoral training at Iwate Medical University with mentorship from Satoshi S. Nishizuka MD, PhD, he joined Dr. Markus Müschen’s laboratory in 2017 at the Beckman Research Institute of the City of Hope. He is currently a Research Scientist in Dr. Müschen’s laboratory at Yale University, and studies the mechanisms and functional significance of autonomous Ca2+ oscillations in oncogenic signaling of multiple B-cell malignancies.
