Dr. Ashwanth Francis is currently recruiting new postdoctoral investigators.
Research and Professional Interests:
The scope of my research program is to understand how viruses reach their replication centers within the nucleus of living cells. Our laboratory uses a combination of quantitative live-cell imaging, single virus tracking and correlative light and cryo-EM (CLEM) techniques to gain mechanistic and structural insights into virus-host interactions, during the many distinct stages of virus replication.
