Meera Nair, PhD

Nair 300x300Dr. Meera Nair is an Associate Professor at the University of California Riverside School of Medicine, where her lab researches the immune response to helminth parasites. Dr. Nair’s fascination for “all things helminths” began in her early years of training at the University of Edinburgh, Scotland, where she completed her PhD on macrophage function in filarial nematode infection. Dr. Nair then pursued her postdoctoral training at the University of Pennsylvania where she discovered the important contribution of a new family of secreted proteins – the Resistin-like molecules (RELM) – in balancing the protective vs pathogenic effects of the immune response to lung helminths.

At UCR, the Nair lab investigates the immune response to infection and inflammatory diseases using preclinical mouse models and clinical samples. The ultimate goal of the lab is to identify protective or pathogenic immune pathways that can be targeted for diagnostic or therapeutic purposes. Using mouse helminth infection models, the lab investigates macrophages as first responders to infection, with the focus on their gene expression profiles, their interaction with the parasitic worm, and their function in tissue repair.

In addition to Immunology research, Dr. Nair is passionate about teaching postdoctoral scientists, and graduate and medical students: she won the Best Lecturer award in 2018 and 2020, the Outstanding Block Director award in 2019, 2021 and 2022, and teaches the Biology of Parasitism summer course in Woods Hole, Massachusetts.
