Recognition & Awards

As a sole PI, Dr. Dshalalow was singly awarded by the National Science Foundation, National Security Agency, and US Army. He was nominated several times for academic and research excellence. He was also a co-PI in one National Science Foundation award. Dr. Dshalalow has also been a participant of joint biomath research teams, awarded by the National Science Foundation.

Research

Dr. Dshalalow published 127 research articles as well as four books. He developed the theory of first excess-level processes, used in stochastic finance, game theory, queueing, established consistency of stochastic estimators of mutation rates of cells, introduced and formalized modulated random measures (on topological spaces) and established ergodic theorems for modulated random measures. The latter are used in telecommunications, stochastic processes and queueing theory with random perturbations.

Dr. Dshalalow is currently involved in research on reliabilitym strategic defense of stochastic networks, antagonistic stochastic games, applications of stochastics in biology including cancer research, queueing, random measures, and stochastiic finance.
