Dr. Tatiana T. Marquez-Lago is Associate Professor in the Department of Genetics, UAB Heersink School of Medicine, and PI of the Marquez-Lago lab (Microbiome and Translational Systems Biology) lab. Within the School of Medicine, she is also affiliated with the Department of Microbiology, the Department of Cell, Developmental and Integrative Biology, the UAB Center for Clinical and Translational Science, the O’Neal Comprehensive Cancer Center, and the Gregory Fleming James Cystic Fibrosis Research Center. She is additionally affiliated with the Department of Biology, UAB College of Arts and Sciences.

Her interdisciplinary lab studies and elucidates functional relationships between human hosts and their microbiomes (with their respective metabolome and metatranscriptome) using experimental and computational methods, with the ultimate goal of developing predictive quantitative models for clinical translation and bioengineering applications. Other lines of research in her lab relate to antibiotic resistance evolution and control strategies, as well as development of multi-omics bioinformatics and AI tools for fundamental and translational research.

In her spare time, Dr. Marquez-Lago enjoys travelling, hiking, DIY, and reading. She also spends time exploring new food recipes and playing board games with family and friends.
