Skin Biology Research @ UC Irvine
UC Irvine’s skin biology community brings together investigators across Dermatology, Biological Chemistry, Microbiology and Molecular Genetics, Developmental and Cell Biology, Pharmacology, Engineering, and Computer Science. This cross-departmental structure has created a uniquely collaborative research environment focused on cutaneous biology, disease mechanisms, and translational discovery. For residents who seek a career that integrates science and medicine, UCI offers the resources of a large research enterprise with the mentorship and cohesion of a focused program.
UCI is one of only a small number of dermatology programs nationwide to hold both a NIAMS T32 Research Training Grant and a P30 Skin Cancer Center Grant, as well as access to the UCI K12 Mentored Career Development Program that provides structured support for early-stage physician-scientists transitioning to faculty roles. These awards reflect institutional strength in skin research and faculty development that provide a robust platform and resources for physician-scientists, including access to cores, career resources, seed funding, interdisciplinary mentorship, and structured research training.
Our program is designed to support residents who aim to build an academic career through scientific inquiry, innovation, and patient-focused discovery. Trainees benefit from individualized mentorship, exposure to diverse investigative approaches, and a culture that encourages collaboration over competition. The result is a training environment where residents will grow as clinicians and researchers while developing the skills and independence needed for long-term success in academic dermatology.

Publications
Funding and Resources
UC Irvine’s skin research community is supported by strong and diversified NIH funding, reflecting our national impact in cutaneous biology, cancer, inflammation, and regenerative medicine. For fiscal year 2025, our faculty in skin biology were the principal investigators for NIH grants totaling $9.8 million in funding, with additional $2.5 million in foundation and industry supported grants. This funding base sustains a research environment with robust infrastructure, collaborative opportunities, and stable support for long-term scientific growth.
UCI is one of only a few institutions with three major NIH mechanisms that directly support dermatology research and training:
• T32 Research Training Grant
Provides structured research training, career development programming, and dedicated support for residents and postdoctoral trainees. The T32 supports protected research time, grant-writing workshops, individualized mentoring committees, and pathways to develop a sustained research focus during residency and fellowship.
• P30 Skin Cancer Center Grant
Supports shared resources and research cores, interdisciplinary pilot funding, seminar series, and visiting professor programs. Trainees benefit from access to advanced technologies (genomics, imaging, bioinformatics, and tissue cores), as well as a collaborative scientific community that spans multiple departments and schools.
• K12 Mentored Career Development Program
Supports the transition from trainee to junior faculty by supporting protected research time, formal career development activities, and mentored research support. This mechanism helps promising physician-scientists bridge the critical and vulnerable early-faculty phase, establish funding, and launch an independent research trajectory.
Our programs provide a comprehensive ecosystem of support from residency through independence, designed to help physician-scientists build impactful academic careers.
Education and Training
UC Irvine offers a structured and supportive physician-scientist pathway that integrates research training with world-class clinical education. Our goal is to help residents establish a strong scientific foundation early, develop a focused project during residency, and transition seamlessly into a productive postdoctoral and early faculty phase.
Early Mentorship and Planning (PGY-2 / Year 1 of Dermatology Residency)
Residents meet with program leadership and are paired with a research mentor during their first year. Together, they explore research interests, identify potential laboratory mentors, and develop an individualized training plan that aligns with long-term career goals.
Research Preparation and Skill-Building (PGY-3 / Year 2)
Residents receive six weeks of elective time to refine their project concept and prepare for active investigation. This period is used to meet with mentors, write IRB protocols, pursue pilot or seed grant funding, develop feasibility data, and build the foundation for a successful research phase.
Dedicated Research Immersion (PGY-4 / Year 3)
Residents may devote up to six months of protected laboratory time to launch their research project in earnest, supported by their mentor and a structured oversight committee. This phase emphasizes productivity, data generation, and positioning the resident for competitive fellowship, postdoctoral, or career development opportunities.
Research Development + Attending Role (PGY-5+)
Following residency, physician-scientist trainees transition into an attending physician role with 1–2 half-days of clinic and the remainder protected for research. Funding may be supported by the NIH T32, other institutional mechanisms, or individual awards (such as F32 or foundation grants), with the goal of building momentum toward independence.
Trainees prepare for and transition onto K08, K01, or K12 career development awards, benefiting from extensive institutional support for grant writing, career development, and mentorship. The program’s structure is designed to produce competitive applicants for early-stage faculty positions and independent research programs.
Training Ecosystem and Professional Development
Education is enhanced by the rich training environment supported by the T32, P30, and K12 programs, including:
-
Research-in-progress seminars and invited lectures
-
Grant writing workshops and mentoring committees
-
ICTS programs for clinical and translational research
-
Human subjects research education and IRB support
-
Access to institutional grants, cores, and pilot funding
-
Interdisciplinary journal clubs and trainee networking events
Together, these opportunities create a comprehensive, longitudinal pathway that supports physician-scientists from residency through early faculty positions.
