Dr. Liangdan Sun is a renowned professor and Vice President of the North China University of Science and Technology (NCUST) in Tangshan, Hebei Province, China. He is the Director of the Health Science Center, the Director of the Inflammation and Immune Diseases Laboratory of NCUST, and a Visiting Scholar at the University of Colorado and the Royal Swedish Academy of Engineering Sciences.

Dr. Sun’s primary research focuses on translational genomics, precision medicine, and mechanisms of genetic susceptibility to inflammation and immune diseases. He has identified over 200 susceptibility genes and diagnostic biomarkers for 40 diseases. Moreover, he has constructed a unique precision variation database of the whole Human Leukocyte Antigens (HLA) based on 10,000 samples from the Chinese population. He has created genome-wide variation maps for different diseases through genome-wide association and sequencing studies and demonstrated the mechanisms of genetic susceptibilities and etiologies. This research has provided necessary evidence for the precision medicine of these diseases.

Dr. Sun is a prolific author with over 210 published papers. His work has been featured in prestigious journals such as Nat Genet, New Engl J Med, and Nat Commun. He has been cited more than 12,000 times, including publications in top-tier journals such as Nature, Cell, Science, and New Engl J Med.

Look Beyond My Skin: World Psoriasis Day 2026

World Psoriasis Day, observed each year on October 29, was launched by the International Federation of Psoriasis Associations (IFPA) in 2004 to give a voice to the more than 125 million people worldwide living with psoriasis and psoriatic arthritis. To mark this year’s observance, IPC joined the Latin American Society of Psoriasis and Dermoimmunology (SOLAPSO) and the Skin Inflammation and Psoriasis International Network (SPIN) to create a video series around the theme “Look Beyond My Skin,” featuring voices from all three organizations. Missed the videos on social media? Watch the full series on the IPC YouTube channel.

Introducing Take Two with IPC: Expert Talks in Two Minutes

Take Two with IPC gives a longer presentation a second life in two minutes. Each video takes an expert talk IPC has already published (a Take Ten recording or a symposium presentation) and condenses the clinical substance. The series launched this month alongside the World Psoriasis Day campaign with four videos on pediatric psoriasis: Psoriasis Look-Alikes and Anti-TNF-α Induced Skin Eruptions with IPC Board Member Amy Paller, MS, MD; Conventional Therapies with IPC Councilor Mona El-Kalioby, MBBCh, MSc, MD; and Phototherapy in Pediatric Psoriasis with Fernando Valenzuela, MD. New Take Two videos will be featured each month, drawn from the Take Ten with IPC library and recordings from IPC symposia, with a link to the full presentation for each.

Sex Differences in Psoriasis

In this Take Ten with IPC video, Juul van den Reek and PhD candidate Liana Barenbrug discuss sex differences in psoriasis, why these distinctions matter, what current research tells us, and which areas should be prioritized in future psoriasis research.
