CBE Seminar: Interaction networks in microbial communities
- Thursday, April 1, 2021 from 10:00am to 11:00am
Dr. Alma Dal Co is a postdoctoral fellow of engineering and applied sciences at Harvard University, where she works with Prof. Michael P. Brenner on how interactions between entities at one level give rise to functionality at a higher level of organization in the context of microbial ecology.
Abstract: Communities of interacting microbes perform fundamental processes on Earth, such as cycling the elements and shaping the health of animals and humans. The processes that these microbial communities perform arise from a dense network of interactions between individual cells. Most microbial communities are spatially structured systems, where cells move little, thus interactions occur mostly between cells close in space. Therefore, the spatial arrangement of different species can affect the processes that the whole community performs. My goal is to uncover how the local interactions between cells determine community-level processes. To do so, I look at synthetic bacterial communities under the microscope at a resolution that allows me to observe both the individual cells and the community as a whole. I measure properties of the single cells, like their growth and their phenotype, and I use mathematical modeling to uncover how these individual-level properties determine community-level properties.
