Dr. Lazar-Molnar completed her PhD degree at the Semmelweis University School of Medicine in 2002 in the Department of Genetics, Cell and Immunobiology. Prior to that, she obtained a degree in Pharmacy at the University of Medicine and Pharmacy in Targu Mures, Romania.

After obtaining her PhD, she moved to New York City, and became a postdoctoral fellow in the Department of Microbiology and Immunology at the Albert Einstein College of Medicine, where she studied T cell immunology, specifically the structure and function of checkpoint inhibitor PD-1 and its ligands. She then decided to follow her interest in clinical applications of immunology and completed a clinical immunology fellowship at the University of Utah, combined with a director-in-training experience in histocompatibility and immunogenetics. She is double board certified by the American Board of Medical Laboratory Immunology (ABMLI), and by the American College of Histocompatibility and Immunogenetics (Fellow of ACHI). She has an academic appointment in the Department of Pathology at the University of Utah School of Medicine, and serves as the director of the Histocompatibility & Immunogenetics Laboratory at the University of Utah Health, and as a medical director in the Immunology Division at the ARUP reference laboratory in Salt Lake City. As of 2020, she is the director of the Clinical Immunology Fellowship in the Department of Pathology at the University of Utah.

Dr. Lazar-Molnar has strong interest in diagnostic immunology including transplantation testing, immunogenetics, cellular immunology, and immunogenicity testing for monoclonal antibody therapeutics. She has been active member of multiple scientific societies, primarily the American Society for Histocompatibility and Immunogenetics (ASHI) and the Association of Medical Laboratory Immunologists (ASHI). She serves on several ASHI committees, including the Publications Committee and the ACHI Laboratory Director Examination Committee. Dr. Lazar-Molnar has been member of AMLI since 2013. She was a member of the Scientific Affairs Committee between 2017 and 2019, and member of the annual meeting planning committee for the 2018 and 2019 AMLI annual meetings. Most recently she was member of the AMLI Education Committee (2019-2021). She attended and gave presentations and served as session co-chair at several AMLI meetings. Her goals are to promote the field of diagnostic immunology by evaluating and implementing new technologies, raise awareness about the challenges, opportunities, and complexities that exist in the field, and to attract new trainees and scientists to the area of clinical immunology.
