Student recruitment
I am recruiting masters and PhD students. Currently, I am working on the design of optimal insurance/reinsurance but I am open to various actuarial decision making problems. I am also interested in reliability analysis, optimal inspection and maintenance schedule, clustering of financial assets. I welcome students with math, stats, actuarial science background to inquire and apply, especially those who are strongly interested in research. A solid foundation in applied math and programming is an asset.
