Teaching
Dr. Weihang Chai is the course chair for the immunology curriculum for WWAMI first-year medical students. She has mentored graduate students and trained postdoctoral fellows at WSU. She currently has four postdoctoral trainees in her research lab, and is on dissertation committees for graduate students from the School of Molecular Biosciences and College of Pharmacy.

Research
Research in our lab focuses on understanding the molecular and cellular processes related to telomeres in cancer and normal cells. Telomeres are sections of DNA that protect the ends of chromosomes and keep genetic information from becoming damaged. We are particularly interested in understanding telomere DNA is maintained in human cells. We study how various proteins interacts with telomeres and how mutations in these genes make telomeres vulnerable, contributing to the growth of cancers and premature aging.
