Robert L Modlin

Dr. Robert L. Modlin is a Professor of Medicine and Microbiology, Immunology & Molecular Genetics at the David Geffen School of Medicine, UCLA. Holding the Arnold W. Klein Chair in Dermatology, his research spans immunology, dermatology, and host-pathogen interactions.

• Key Research Themes: IL-26 signaling in antimicrobial defense, spatial transcriptomics of skin diseases, vitamin D metabolism in immunity, Toll-like receptor activation, and granuloma immunobiology.
• Major Grants: NIH R01s in dermatology and immunology (2019-2024), T32 training programs, and R21/R21/R01 grants on acne, tuberculosis, and leprosy (2005-2024).
• Scientific Leadership: Principal investigator on over 15 NIH grants, including P50 Immunobiology of Leprosy and U01 CD1-targeted vaccination studies.

His publications focus on inflammatory skin diseases (psoriasis, hidradenitis, acne), antimicrobial mechanisms in tuberculosis/leprosy, and systems biology of fibrosis. Collaborations include leading institutions in dermatology, immunology, and infectious diseases.
