New manuscript on self-sustaining closed microbial communities!
BIG NEWS: We are thankful for the opportunity we have had to do science at UIUC - especially for the remarkable colleagues, students, and staff. However, we are excited to announce that our laboratory is moving to The University of Chicago @ the Department of Ecology and Evolution and the Center for the Physics of Evolving Systems. We look forward to joining the vibrant intellectual community at UChicago.
Students and post-docs interested in joining our research effort should contact Seppe. We invite anyone with interests in theory or experiments.
The KiTP EcoEvo workshop has been postponed until July/August 2021 due to COVID-19.

What we do: Evolution has constructed persistent and functional biological from the molecular to organismal and ecological scales. What are the principles by which evolution has generated these systems? What aspects of eco-evolutionary processes can be predicted? We are asking these questions at the ecological level in the context of microbial communities - key metabolic players in the global eco-evolutionary process. In particular, we would like to know: How do microbial communities function? What are the molecular mechanisms? Why has evolution resulted in the microbial community structures we observe in Nature?
The incredible successes of physics in describing non-living matter have taught us that we must do phenomenology first -- that is, provide quantitative, phenomenological, descriptions of precisely how microbial communities function. In essence, we need to establish which are the right variables to describe microbial community structure, metabolic function, and dynamics. Armed with this knowledge we can then ask - what are the molecular and mechanistic bases of these variables? Finally, why has the evolutionary process resulted in the collective variables we observe? To accomplish this we:
(1) Study ensembles of communities with well-defined functional properties and uncover the relevant variables for mapping structure to function using statistical and phenomenological methods.
(2) Understand what molecular players and mechanisms are responsible for the collective variables describing community structure and function -- interactions, gene expression, metabolism.
(3) Using synthetic communities in the laboratory and observations on natural ecosystems we hope to determine why the structure-function relationships we observe in (1) and the mechanisms of (2) are present in natural microbial ecosystems.
We ask the questions posed above in three related types of microbial communities where the structure (taxonomic, metagenomic, abundances) and function (metabolic) are sharply defined and quantifiable:
We are a group of physicists, applied mathematicians, ecologists, and evolutionary biologists. We are always looking for new members who are excited about biology, ecology, and making new measurements - get in touch!
