Dr. Merry-Lynn McDonald is the Director of Integrative ‘Omics and an Associate Professor of Medicine in the UAB Division of Pulmonary, Allergy, and Critical Care Medicine. She is a genetic epidemiologist with interests in the analysis of complex traits and diseases including COPD, cachexia, sarcopenia, osteoarthritis and smoking behaviors such as menthol. Her lab is involved with some of the most cutting-edge studies including the Million Veterans Program (MVP), All of Us and the Trans-Omics for Precision Medicine (TOPMed) Initiative. Originally from Canada, Dr. McDonald received her undergraduate degree from the University of Waterloo, MSc from the University of Saskatchewan and her PhD from Baylor College of Medicine in Houston, TX. She completed post-doctoral training at Brigham and Women’s Hospital/ Harvard School of Medicine.


Alison Rocco is a bioinformatician focused on the application of pharmacogenetic enrichment scores to advance precision medicine for patients with osteoarthritis. She is an expert in development and implementation of applications in cloud computing environments.


Dr. Kaleen Lavin is a research scientist focused on health, performance, and resilience. She earned a bachelor’s degree in biology from Georgetown University; a master’s in sports nutrition and exercise science from Marywood University; and a Ph.D. human bioenergetics from Ball State University. She is particularly interested in integrating bioinformatics analysis pipelines that detect differential expression with more sophisticated networks-based approaches in order to reveal novel connections between genes and across ‘omes. Her experience with skeletal muscle biology and exercise physiology provides critical context for data interpretation and connecting molecular patterns to whole-body and/or systems-level health.


Dr. Joe Chiles is an Assistant Professor in the Division of Pulmonary, Allergy, and Critical Care Medicine.  He completed medical school at the University of Kentucky and residency in internal medicine at the Ohio State University Wexner Medical Center before coming to UAB for fellowship.  His projects in the lab center around the genetics of COPD and acute respiratory distress syndrome (ARDS) and he is pursuing clinical research on ARDS, especially in the context of the recent COVID-19 epidemic.


Chelsea Nguyen is a PhD student in the Graduate Biomedical Sciences Program (Genetics, Genomics, and Bioinformatics theme). She completed her Bachelor of Science (B.S.) in Biology with a minor in Health Science with both wet lab and computational experience at Columbus State University in Columbus, Georgia. Her research project in the lab focuses on identifying and harnessing genetic variation in veterans with osteoarthritis (OA) and/or post-traumatic osteoarthritis (PTOA) using multi omics methods.


Hanna Sothers is a PhD student in the Biomedical Sciences Program (Genetics, Genomics, and Bioinformatics theme). She completed her Bachelor of Science (B.S.) in Biology with minors in Computer Science and Chemistry at the University of Alabama in Huntsville. Her previous experience includes undergraduate research at HudsonAlpha Institute for Biotechnology as well as working in a clinical laboratory.


Bitota Lukusa-Sawalena is a PhD student in the Biomedical Sciences Genetics, Genomics, and Bioinformatics Theme. Bitota is skilled in data analyses and curation, qPCR, RNA extraction, and computational biology. Before coming to UAB, she completed a Bachelor of Science (B.S.) in Biology from Savannah State University.


Kumaran Chowdary Paruchuri is a clinical research study coordinator leading the recruitment of participants with COPD to study cachexia. He completed a Bachelor of Dental Surgery in India, a Masters of Public Health in Epidemiology and Biostatistics at the University of Souther Mississippi and a Dental Public Health Residency at Temple University.


Dr. Meena (Meenakshi) Sridhar is an Assistant Professor in the Division of Pulmonary, Allergy, and Critical Care Medicine. She attended medical school at the University of Delhi, India, and Internal Medicine residency at the University of Arizona- Phoenix before her time at UAB. Her research projects in the lab focus on outcomes in patients with interstitial lung disease specifically the effect of musculoskeletal comorbidities. She is also pursuing clinical research on the role of mechanical circulatory support in the management of Pulmonary Embolisms.
