The #UConn Microbial Ecophysiology Lab studies the biology of methane-producing microbes (methanogens or methanogenic archaea) and their role in ecosystems & host-associated microbiomes.
We are people who do science, but we also actively work to include diverse perspectives in higher education.

A family of linear plasmid phages that detect a quorum-sensing autoinducer exists in multiple bacterial species | mBio
The discovery of quorum-sensing responsive linear plasmid phages has transformed understanding
of phage-bacterial interactions by demonstrating inter-domain chemical communication.
