Overview

Dr. Wan has extensive training in molecular biology, cell biology and immunology. She is an expert in the field of novel assay development, and has extensive experience in academic research work. Dr. Wan mastered novel ELISA assays for the entire murine IGF/IGFBP system and for human and murine humanin and have done lots of IGFs, IGFBPs and humanin assays with the other collaborators, and developed new  assays for mitochondria small peptides (MDPs). She has directed core facilities at UCLA and USC, focusing on translation of assays and novel assay development.
