Tomasz J. Kozubowski

Professor

Summary

Following a graduate study of applied mathematics at the University of Warsaw, Poland, Dr. Tomasz J. Kozubowski received MS in Statistics from the University of Texas, El Paso, and Ph.D. in Statistics and Applied Probability from University of California, Santa Barbara. He is currently a Professor in the Department of Mathematics & Statistics at the Â鶹´«Ã½AV.

Dr. Kozubowski works in the general area of stochastic modeling of natural phenomena in variety of fields, including climate research, geosciences, finance, and economics. His research interests include distribution theory, Laplace distribution and its generalizations, limit theory for random sums, heavy tailed distributions, extremes, mathematical statistics, financial and insurance mathematics, stochastic models for hydro-climatic phenomena, and fractal scaling processes. He has co-authored over 130 research publications, including two monographs.

Dr. Kozubowski has served as an undergraduate advisor in mathematics and statistics for many years and has an extensive experience as a graduate advisor and mentor, having directed research of numerous graduate students and postdoctoral researchers.

Dr. Kozubowski is currently an editorial board member of several academic journals and an active reviewer, having refereed for over 100 different academic journals. With the 2016 Sentinel of Science Reward, he was recognized by Publons as one of the top researchers contributing to the peer review in the field of mathematics.
