I am very happy and much honoured to be selected as the first recipient of the SOA Actuarial Science Early Career Award from the Society of Actuaries!
July 20, 2021
Posted a new paper on arXiv: A unified framework for bandit multiple testing. In this paper we continue to explore multi-armed bandit problems with e-values and the e-BH procedure.
July 10, 2021
Posted two new papers on arXiv and SSRN; see the Publications tab. One paper is on optimal insurance and the other one is on variance comparison of estimators for stochastic gradients.
