Professor Ebrahimi is a leading researcher in the areas of reliability theory and survival analysis, information theoretic statistics and modeling, and statistical applications in engineering and medical sciences.

Statistical techniques that he developed ultimately help companies determine the reliability of new products, from automobiles to electronics, and help doctors predict remission and relapse of certain diseases.

Collaborating with NIU graduate-level students, he now is developing statistical methodology relating the probability of survival of a cancer patient to his or her DNA profile. Additionally, one of his advanced students is working on ways to link the occurrence of a disease, such as high blood pressure, to certain features in a chromosome.

Ebrahimi earned his Ph.D. at Iowa State University and joined the NIU faculty in 1982. He is a founding member of NIU’s Division of Statistics and has taught nearly all of its courses.

Ebrahimi also has published over 120 research articles—on average about five per year—with many appearing in top journals. His groundbreaking work is used in numerous fields, including with NIU collaborators, and is supported by the National Institutes of Health, the U.S. Air Force and the National Science Foundation.

Ebrahimi is an elected member of the International Statistical Institute. His stature as a leader in several branches of his field was recognized with his election to a Fellow of the American Statistical Association. The number of fellows is restricted to one-third of one percent of the organization’s membership, and the honor is regarded as an accolade given only to the top practitioners who have achieved international recognition.
