Research Activities
Dr. Ibrahim's areas of research focus are Bayesian inference, missing data problems, medical imaging analysis and genomics. He received a Doctor of Philosophy degree in statistics from the University of Minnesota in 1988. With more than 22 years of experience working in cancer clinical trials, Ibrahim directs the UNC Center for Innovative Clinical Trials -- one of eight Gillings Innovation Labs funded by a gift to the School from Dr. Dennis and Joan Gillings.

Dr. Ibrahim is also the director of graduate studies in the Department of Biostatistics at the Gillings School, as well as the program director of the cancer genomics training grant in the same department.
He has served on several national committees and study sections, including as the section chair of the Section on Bayesian Statistical Science of the American Statistical Association and the Biostatistical Methods and Research Design (BMRD) NIH Study Section. He has also served as the associate editor for several statistical journals and is currently serving and the editor of the Journal of the American Statistical Society (JASA) - Application and Case Studies.

Dr. Ibrahim has published more than 275 research papers, mostly in the top statistical journals. He also has published two advanced graduate-level books on Bayesian survival analysis and Monte Carlo methods in Bayesian computation. He is an elected fellow of the American Statistical Association and the Institute of Mathematical Statistics, and an elected member of the International Statistical Institute.
