Yang Shen is an Associate Professor and an ARC DECRA (Discovery Early Career Research Award) Fellow in the School of Risk and Actuarial Studies and an Associate Investigator of CEPAR. He obtained his PhD in Actuarial Studies from Macquarie University in 2014. He worked as a Research Fellow at CEPAR from 2013 to 2015 and an Assistant Professor at York University from 2015 to 2019. His current research interests are at the intersection of actuarial studies and financial mathematics, including retirement planning, longevity and health risk, optimal insurance and reinsurance, pricing and hedging of insurance and annuity products, portfolio optimization and game theory. Yang has published in all top-tier actuarial journals (e.g. IME, ASTIN, SAJ, NAAJ), and top journals in control theory (e.g. Automatica), and major journals in financial mathematics (e.g. SIFIN) and operations research (e.g. EJOR). According to Google Scholar, as of March 2022, his publications were cited over 1000 times and had an h-index of 21. His research has been funded by major funding agencies and professional organisations, such as ARC, NSERC, SOA, CAS, etc. Yang was the first winner of DECRA in the field of actuarial studies since the inception of this award.
