Iztok Hozo is a Professor at Indiana University Northwest. After completing his doctoral thesis in applied mathematics at University of Michigan, his main research interests became applications of mathematical modelling and decision theory in Medical applications. Mainly collaborating with Dr. Djulbegovic, he published 75 articles in peer-reviewed scientific journals.

In addition to receiving several Indiana University awards for excellence in research, Dr. Hozo won prestigious teaching awards in recognition of his expertise in the classroom and curriculum development.
He is a mathematician capable of translating real scientific and medical problems into mathematical language. His mathematical acumen has enabled him to tackle the vast array of diverse medical problems. Over the years he has made contribution to statistical analysis of clinical data and improvement in techniques of meta-analysis, tackled the issues of diagnostic tests using information theory approach, recast the issue of clinical trials from game theory point of view, developed new methods for decision-making, including a novel method based on mathematical modelling of regret, and helped develop the first mathematical model of decision-making that is based on dual processing theory and developed a new theory called acceptable regret, which could explain many phenomena in the diagnostic and treatment decisions in medicine.
According to Google Scholar, his current h-index is 25. One of his published articles has over 4200 citations (written jointly with Dr. Djulbegovic and Mrs. Pudar-Hozo).
