Research Interests


Dr. Rahman is interested in repurposing antipsychotic drugs for cancer treatment. Antipsychotic drugs have strong preclinical evidence of anti-tumor molecular properties. Dr. Rahman and colleagues were recently awarded a Siteman Investment Program grant to conduct a large retrospective cohort pharmaco-epidemiology study on antipsychotics and breast cancer. Further studies are needed to determine if antipsychotics can play a role in the treatment of cancers.

Dr. Rahman and colleagues have recently determined that extreme overvalued beliefs are different from delusions and obsessions and that extreme violence such as terrorism and mass shootings usually stem from such beliefs. He has studied mass shootings and terrorism related to this construct. He has several publications and over 300 media placements on this topic. He is working with other terrorism and lone actor violence researchers to better define cognitive drivers of lone actor violence. Dr. Rahman conducts forensic evaluations and has been a consultant at both the State and Federal levels on issues such as insanity, competency to stand trial, death penalty mitigation and civil cases.

Dr. Rahman has also published articles on ethical issues in psychiatry including the use of pharmacogenomics tests in clinical practice and how they may raise unintended harms. He has also written a guide for clinicians to help make ethical decisions when utilizing trackable pill technology.
