Studying microbial evolution

through computation, experiment, and theory


Welcome to the Baym Lab at Harvard Medical School, started in July 2017!

Antibiotic resistance is one of the defining public health threats of our time. Every time a new antibiotic has been introduced, resistance rapidly follows. We study how resistance evolves with the goal of making practical interventions that take into account, and even anticipates, pathogen evolution. This relies on both experimental recapitulation of the process of resistance evolution as well as the study of genomic data from real-world infections.

More broadly, antibiotic resistance provides an excellent model system for evolution. In a sense, we as a society have been performing a directed evolution experiment in pathogens on a worldwide scale. Only now, with rapid sequencing, is the technology becoming available to understand the results.

Or, to describe what we do in Up Goer Five terms:

Very small living things that can not be killed hurt more and more people each year. People used to find many ways to kill them, but it is getting harder to find new ones that work. We study how the small things change over time to avoid being killed by us. We use this to find approaches to fighting the small things which expect these changes and change with them. We try to make approaches that can be used by doctors to keep killing the small things and to keep them from hurting people.

Our research is supported by the David and Lucile Packard Foundation and the NIH NIGMS.
