Research & publications

Dr. Xu is actively involved in several research projects related to melanoma and other skin cancers. Along with her co-PI, Dr. Vladimir S. Spiegelman, she is working on a project on cutaneous squamous cell carcinoma (SCC) in non-transplant and transplant patients. It is hoped that this research will lead to pre-operative treatment to reduce the size of the tumor or post-operative treatment to enhance the cure rate. She is involved in a project with Dr. Mark Albertini to study immune responses to melanoma. She is also involved in a project led by Andrew Sheinis, UW Professor of Astronomy, to determine if an imaging technology developed for Astronomy can be used to detect early melanoma as well as to detect cancer margins prior to surgical removal.
