About Jae Kyung (JK)

Before joining the UNSW in July 2017, Jae Kyung (JK) Woo was a postdoctoral fellow at Mathematics & Statistics, Concordia University (09/2010-06/2011), and spent one year as Assistant Professor at Statistics, Columbia University (07/2011-06/2012). Then she moved to Statistics & Actuarial Science, the University of Hong Kong as Assistant Professor and worked for five years. She completed her MMath and Ph.D. at Statistics & Actuarial Science, the University of Waterloo and her undergraduate studies at Statistics & BBA, Ewha Womans University.

Her research interests lie in the area of risk theory, reliability theory, aggregate claim analysis, Queueing theory, and renewal processes.

She is a Fellow of the Society of Actuaries (FSA), and a Chartered Enterprise Risk Analyst (CERA) received from the SOA.
