joe hakim md phd pgy1Joe Hakim, M.D., Ph.D. - PGY 1

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. He is currently on the hematology/oncology research pathway, and is interested in incorporating DNA sequencing and bioinformatics to determine the structure, stability, and function of gut microbial communities in the individual-specific development of oncological diseases, associated disorders, and response to therapies.

Jingnan HanVibhu Parcha, MBBS - PGY 2

Dr. Parcha received his medical degree from Dr. RP Governmental Medical College, India, in 2019. After graduating, he pursued a post-graduate clinical research fellowship in the UAB Cardiovascular Clinical and Translational Research Program under Dr. Arora. He aspires to establish a comprehensive clinical program for patients with inherited cardiomyopathies at UAB, fostering collaboration across specialties, including advanced heart failure, cardiac surgery, cardiac rehabilitation, genetic counseling, and nursing. Through rigorous patient-oriented research, Dr. Parcha has accrued experience in clinical trials (mechanistic and therapeutic), computational biology, biomarkers, advanced biostatistics, genomics, clinical risk prediction, and health disparities research. He seeks to integrate these skills into two key research themes moving forward:

  1. Implementing precision medicine approaches to improve clinical outcomes in cardiorenal and metabolic disease patients, harnessing tools such as artificial intelligence, multi-omics, and advanced imaging.

  2. Applying patient-derived induced pluripotent stem cell-derived cardiomyocyte models to advance diagnostics, prognostics, and therapeutics in precision cardiovascular medicine.

Through these broad themes, he is committed to rigorous and innovative research and aspires to bridge the gap between bench and bedside, ultimately translating scientific discoveries into tangible improvements in patient care. Given his passion and dedication to improving outcomes in cardio-renal-metabolic diseases, Dr. Parcha is excited to pursue his training through the ABIM Research Pathway at UAB.

Jordan Stephen1Stephen Jordan, MD, PhD

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 PhD 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.

Gregory Payne1Victor Lin, MD, PhD

Dr. Lin completed his Sc.B. in Biochemistry with honors at Brown University before going on to train in the NIH-supported Medical Scientist Training Program (MSTP) at the University of Alabama at Birmingham (UAB), receiving both an MD and a PhD in Cell Biology. His dissertation research in the lab of Fang-Tsyr (Fannie) Lin centered around thyroid hormone receptor-interacting protein 6 (TRIP6), an adaptor protein that is upregulated in a number of malignancies, including ovarian cancer and glioblastoma. His work illustrated how TRIP6 specifically regulates p27KIP1, a CDK inhibitor that is an important prognostic determinant in cancer. He went on to complete his residency in Internal Medicine and fellowship in Hematology and Oncology as part of the ABIM Research Pathway at UAB. During this time, he did his postdoctoral fellowship in the lab of Lalita Shevde-Samant, where his research focused on the role of the Hedgehog pathway in regulating DNA repair, particularly the role of GLI1 in enabling the repair of double-strand breaks in ribosomal DNA (rDNA). After completing his training, he joined the Department of Medicine at UAB as an Instructor in the Division of Hematology and Oncology with a clinical focus in lung cancer and sarcoma and a research focus in precision oncology.
