Loren Gragert, PhD – Principal Investigator

Dr. Gragert’s career path in immunogenetics began at the US bone marrow donor registry National Marrow Donor Program (NMDP) in the Bioinformatics Research department led by Martin Maiers. His research projects at NMDP translated directly into operational implementations of informatics systems that enabled rapid identification of HLA-matched registry donors. An important early mentor and collaborator was Dr. Bill Klitz from the Department of Genetics at University of California-Berkeley, who gave him comprehensive training in statistical population genetics. He pursued his PhD coursework at University of Minnesota (UMN) while holding a full-time position at NMDP, enabling him to take new computer science and statistical methods straight from the classroom into my projects. He was the second PhD grantee for UMN’s BICB program, which is a unique private-partnership with Mayo Clinic, IBM, and later NMDP aimed at providing advanced training for informatics professionals in industry

Dr. Gragert primary focus as an Early Stage Investigator at Tulane University School of Medicine is to apply the HLA informatics technologies and registry datasets developed at NMDP towards innovating in HLA genetic association studies in solid organ transplantation and cancer. The high impact translational environment that nurtured his success at NMDP is further enhanced at Tulane with his new proximity to experienced academic researchers and clinicians. My tight-knit relationship with NMDP continues through sponsored projects, and his collaborations with leaders in the field of immunogenetics continues to expand. In July 2020, Dr. Gragert began his training as a Histocompatibility Lab Director.

Current Members

D. Giovanni Biagini, PhD Student, Biomedical Sciences Program

As a PhD student and member of the Gragert Lab at the Tulane Cancer Center, my research primarily focuses on using artificial intelligence coupled with immunogenetics to shed some light on the critical relationship between immunity and organ transplantation. My goal is to develop software tools to better equip physicians, get better outcomes for patients, and improve access and equity in donor-recipient matching.






Marian Dribus, PhD Student, Biomedical Sciences Program

Marian Dribus has a Bachelor of Science in nursing from Southeastern Louisiana University and a Master of Science in microbiology & immunology from Tulane University. She is working toward her PhD in biomedical sciences from Tulane University in the Gragert Lab. Her research focuses on HLA association with hematological diseases. 







Grace Wager, PhD Student, Biomedical Sciences Program

Grace Wager graduated with her BS in Biology from Southeastern Louisiana University where she studied the Systematic Morphometric Geometrics of Imopoema batatas subspecies. She is currently working on helping to find better ways to predict graft failure in solid organ transplant recipients utilizing HLA mismatching. Grace enjoys bioinformatics research based in genetics, infectious disease, microbiology, and neurology.






Past Members

Navchetan Kaur, PhD – Postdoctoral Fellow

Navchetan acquired bioinformatics skills after joining Gragert Lab in September 2016 as postdoctoral fellow. She has contributed to projects on “Improving Matching Algorithms for Transplantation with HLA Genetics”. She has a  PhD in Immunology from Post Graduate Institute of Medical Education and Research, Chandigarh, India,  a tertiary referral center. This has led her to have a  prior experience with Immunopathology diagnostics and HLA testing in a histocompatibility lab. In 2019 Dr. Kaur joined the Atul Butte lab at UCSF as a postdoctoral fellow.



Richard Davis – MD/MPH in Biostatistics

Richard explored the opportunity to learn data science and medical informatics when he joined Gragert Lab in August 2016 as MD/MPH student at Tulane School of Public Health and Tropical Medicine. He contributed to the immune genes association project, while enhancing his own skillset. An aspiring pathologist, he aims to utilize his data skills for Pathology Informatics. Before joining Tulane, Richard did his B.S from Georgia Institute of Technology. Richard joined the M.D Pathology at Duke University Medical Center in North Carolina starting in 2018.
