Current Research

Dr. Wei's team is generally interested in Bacteriology where we challenge bacterial physiology in response to DNA damaging antibiotics (the SOS response): biofilms, motility, vesiculation, and cellular evolution. We are particularly curious about SOS regulation of DNA nanomotors in viruses and bacteria.

Why do you enjoy teaching at SBU?

"I enjoy integrating God’s word and Christian faith into teaching of biological sciences. Also see Romans 1:20."
