About

Overview

Vali Asimit joined Cass in January 2011 as a Lecturer in Actuarial Science. Previously, he had been a Lecturer in Actuarial Science at the University of Manchester for two years. Vali had studied Economics at the Academy of Economic Studies, Bucharest, Romania. He has an MSc in Statistics from the University of Western Ontario, Canada. He pursued his doctoral research on "Dependence Modelling with Applications in Finance and Insurance" at the University of Western Ontario.

Vali is the Associate Editor of the Insurance: Mathematics and Economics journal. As part of his academic work he has published and acted as referee for international statistical and actuarial journals. Vali received the 2010 Fortis Award for the best Insurance: Mathematics and Economics (IME) journal paper presented at the 14th International Congress of IME.
