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 signaling networks of the PD-1 receptor in cancer cells. His clinical responsibilities include the management of patients with different (cutaneous) neoplasms and complex dermatological diseases.
