Areas of Interest
Immunity in Pneumococcal Infections

Dr. LaFon his completed his initial medical training at USF Health Morsani College of Medicine in Tampa, Florida. Following this training, Dr. LaFon completed his internship, residency, and fellowship at the University of Alabama at Birmingham. Following his fellowship, Dr. LaFon began work as an instructor in the UAB Division of Pulmonary, Allergy, and Critical Care Medicine, His current clinical and research interest is immunity in pneumococcal infections .Dr. LaFon has been first author on three peer-reviewed manuscripts written with Dr. Nahm that have been accepted or published. In addition to the manuscript accepted to Journal of Allergy and Clinical Immunology, one manuscript has been published in Journal of Immunological Methods, and another accepted for publication in Transfusion. He regularly attends pulmonary division didactic lectures and conferences. He is planning a K23 submission in middle of 2020.

Dr. LaFon’s research is focused on measuring immune responses to pneumococcal vaccines in order to characterize the immune dysfunction associated with COPD. Since current methods for diagnosing immune dysfunction are inadequate, Dr. LaFon is interested in identifying novel means of evaluating vaccine responses in clinical populations, and applying these techniques to COPD. In particular, he plans to investigate the use of multiplexed opsonophagocytosis assays (MOPA) as an indicator of pneumococcal antibody function in individuals with COPD who experience frequent infections. He is working with Dr. Mark Dransfield to apply analytical techniques used in the Nahm Lab to study clinical populations. Dr. LaFon is currently a co-investigator in a multi-site study of immune parameters in COPD. He is also analyzing vaccine response data in COPD and initiating a study of pneumococcal antibodies in COPD sera. Dr. LaFon conducted a study demonstrating that different laboratories’ assays that measure pneumococcal antibodies generate different results, with the potential to affect clinical diagnosis. He is first-author on a manuscript describing these findings which has been accepted to the Journal of Allergy and Clinical Immunology.
