Christian Posch M.D. Ph.D. 

Head of Dermatology, Vienna Healthcare Group, Austria

The Posch-lab focuses on (skin) cancer biology and inflammatory skin diseases. Why the skin? Because it is accessible, easy to observe+treat, and easy to sample. The skin offers a complex immunological network, a plethora of different inflammatory diseases and a vast variety of different cancer entities. Nowhere on or in the body is the process of aging so visible and obvious - all right in front of your eyes.

Dr. Posch is a board certified physician scientist with nearly 15 years of experience in clinical dermatology and substantial productivity in melanoma and basic cancer research. In previous studies, he has highlighted the critical role of the MAPK, PI3K/AKT/mTOR and cell cycle pathways for NRAS mutant melanoma maintenance. He has also discovered novel signalling networks of the PD-1 receptor on cancer cells. His clinical responsibilities include the management of patients with different (cutaneous) neoplasms and complex dermatological diseases. He was the head of dermato-oncology at the Department for Dermatology at the Technical University of Munich (Klinikum rechts der Isar). Since 2022 he is head of dermatology at the Vienna Healthcare Group.

The Posch-lab is convinced that the fundamental processes of cancer initiation and the biological processes of aging are heavily  intertwined. What if the key to human longevity and healthspan lies in the very entity currently responsible for destroying both in so many - cancer?

Wilson Liao M.D. - dermatologist

University of California San Francisco, CA, USA

Dr. Liao serves as Director of the UCSF Psoriasis and Skin Treatment Center and is deeply engaged in patient care, clinical trials, and basic science research. The Liao laboratory studies the genetics and environmental triggers of psoriasis, a common immune-mediated skin disease. Dr. Liao directs the UCSF Psoriasis Research Initiative and Biobank with over 1,000 subjects, which is used for genetic and translational research studies.


The Liao lab has contributed to the publication of the first two genome-wide association studies in psoriasis and has helped identify over 20 additional risk variants. His lab has identified a genetic similarity between individuals with psoriasis and individuals who have robust immunity against HIV-1. This has highlighted the role of antiviral immune responses in contributing to autoimmune susceptibility.

Collaboration with the POSCHlab:

- Genetics of Hidradenitis suppurativa
