About

Overview

Prof Vladimir Kaishev is a Professor of Actuarial Science at the Faculty of Actuarial Science and Insurance (FASI), Bayes Business School (formerly Cass), City University, London. He joined FASI in 2002. In 2001 he has been a visiting lecturer in actuarial mathematics at the Center of Actuarial Studies, University of Melbourne, Australia.

From 1994 until 2000, Prof Kaishev was Head of the Department of Computational Stochastics at the Institute of Mathematics of the Bulgarian Academy of Sciences. He holds a PhD degree in statistics and information theory from the Moscow Technical University. He has been a visiting researcher at the Mathematics Research Center, University of Wisconsin- Madison, and at the University of California at Los Angeles.

Prof Kaishev has also been a visiting lecturer at the Department of Actuarial Mathematics and Statistics, Heriot-Watt University, Edinburgh, at Sofia University "St. Kliment Ohridski" and has delivered invited lectures at Stanford University (Dept. of Statistics) and at a number of European universities and research institutions. His research interests are in actuarial mathematics, risk and ruin theory, reinsurance modeling, spline-functions and their applications to probability, statistics and actuarial science, competing risks and copulas. He has also worked on a number of applied research and consultancy projects in the field of actuarial science and insurance, chemistry, medicine, ship hydrodynamics.

Prof Kaishev was the initiator of the re-establishment of the Bulgarian Actuarial Society in 1993 and has served as its president from 1993 to 2002. He is also a member of the American Mathematical Society. Prof Kaishev is a referee for international academic journals in the field of actuarial science and stochastics.
