Biography: 

The Decho Microbial Interactions laboratory investigates microbial biofilms and mats, focusing specifically on processes occurring within the extracellular polymer (EPS) matrix. We are interested in looking for carbonate precipitation, quorum sensing (communication), the use of nanoparticles as probes, and searching for signatures of EPS processes in mat fossil systems.
