Dr. Marcela Henao-Tamayo started her flow cytometry research in clinical settings during medical school in Colombia. In 2003 she came to CSU, initially as a graduate student, where she continued studying M. tuberculosis host-pathogen interactions using animal models. Over the last 12 years, she has developed numerous flow cytometry protocols to perform studies on both mice and guineas pigs infected with virulent clinical strains of TB under highly restrictive BSL-3 conditions. She attended formal training courses where she received operator and analysis certifications for several instruments: DakoCytomation MOFlO, 2004; BD LSRII, 2006; BD FACSAria III cell sorting, 2012. She is currently an Assistant Professor in the Department of Microbiology, Immunology and Pathology and oversees all the hazardous/high-risk experiments performed inside the BSL-3 facility with the BD LSR-II and FACSAria III cytometers/sorters. Additionally, Marcela conducts an active research program in immuno-pathology of tuberculosis.
