joe hakim md phd pgy1Joe Hakim, M.D., Ph.D. - PGY 3

Dr. Hakim completed his graduate study at UAB’s Biology Department with an emphasis in molecular genetics and bioinformatics. His dissertation focused on the co-evolutionary interplay of gut microbial communities with their hosts. He later joined the UAB Microbiome Resource Core and UAB Heflin Genomics Institute as a graduate research assistant, forming interdisciplinary collaborations that he continued as a medical student at UAB. These works included developing bioinformatics methods for distinguishing strain-level variation of gut-system bacteria and applying these approaches to determine strain prevalence following fecal microbiome transplants.

Jordan Stephen1Stephen Jordan, M.D., Ph.D.

Dr. Jordan received his undergraduate degree in biophysics from Oklahoma City University and then joined the University of Alabama at Birmingham’s Medical Scientist Training Program (MSTP). He received his Ph.D. in Cell Biology for his work designing a novel malaria vaccine. He was accepted into the ABIM Research Track at UAB and completed his residency in 2013 and Infectious Disease Fellowship in 2015.

Dr. Jordan’s research focuses on understanding the immune response to Chlamydia genital infection under the mentorship of Dr. Geisler. Through collaboration with an ongoing cohort study at the Jefferson County Department of Health he has shown recently that 20% of women who test positive for Chlamydia at the STD clinic clear their infection prior to returning to the STD clinic for treatment. With evidence supporting an immune-mediated etiology for this spontaneous clearance, Dr. Jordan’s focus is on studying the T-cell response to Chlamydia and the cytokine profiles elicited during chlamydia infection to understand how this immune response occurs. Dr. Jordan is a 2014 Honorable Mention awardee for the J. Claude Bennett Award for Excellence in Research. Dr. Jordan is currently and Associate Professor at Indiana University.

Dr. Payne's nationally acclaimed research has garnered substantial support, notably as one of the two inaugural recipients of the prestigious K-equivalent American Heart Association-Harold Amos Medical Faculty Development Program (AHA-AMFDP) Career Development Award in 2018. Furthermore, his research endeavors have thrived, culminating in the receipt of the Young Investigator Award from the American Society of Clinical Investigation (ASCI). Importantly, his research continues to receive steadfast backing from the NIH/NHLBI and a distinguished Clinical Science Research and Development (CSRD) VA Merit Award.

Sunil RangarajanSunil Rangarajan, MBBS

Dr. Rangarajan completed his medical degree at Bangalore Medical College and Research Institute in India, and pursued 2 years of a postdoctoral fellowship at UAB during which he studied the role of age and gender in cisplatin mediated nephrotoxicity. He entered the UAB Internal Medicine ABIM Research Pathway in 2014 and is currently in the final year of a dual fellowship in Medical Oncology and Nephrology (Onconephrology). He was awarded the 2020 Conquer Cancer Foundation of the American Society of Clinical Oncology – Young Investigator Award, which provides funding for his project -Heparanase and renal damage in myeloma. He was recently selected to serve in the Trainee and Early Faculty Council and the Communications Committee of the American Society of Clinical Oncology. Dr. Rangarajan currently serves as a medical oncologist at MultiCare Cancer Center in Takoma, WA.
