Portrait of Sebastian Correa-Gallego

Sebastian Correa-Gallego

Bachelor of Science in Biology

I study how biological systems assemble, organize, and transform across time and environment — and whether the forms life takes are written by rule, or by history and chance.

01Orientation

Evolution and ecology are not subfields of biology — they are its organizing logic, present from the emergence of cellular complexity to the structure of communities in extreme environments. My research interests sit at this intersection: I am drawn to microbial systems as tractable windows into how life assembles, persists, and transforms under ecological and energetic constraint.

This includes questions about community organization along environmental gradients, the physiological and molecular strategies — including cellular resource allocation — that underlie ecological success, and the eco-evolutionary dynamics that connect cellular function to community-level patterns. I am also interested in the quantitative and computational frameworks that make these questions formally tractable, and in connecting field-based inquiry with analytical rigor across biological scales.

Current direction Cellular resource allocation and the predictability of microbial community assembly.

02Research

Two windows on one question.

Outward — microbial communities

Cultivable Microbial Community Structure Along a Light Gradient in a Tropical Volcaniclastic Cave

Undergraduate thesis, Universidad EAFIT. Advised by Prof. Nicolás Pinel Peláez.

In a tropical volcaniclastic cave, a light gradient runs from the entrance to the aphotic zone. Across it, the same cave — under different energetic conditions — produced structurally different microbial communities. Environment as sculptor, community as response; the gradient as the axis that makes the relationship visible.

Inward — cellular constraint

Proteome allocation in osmotrophic yeasts under carbon limitation

ECSO Lab, Purdue University. Visiting Student Intern, 2025–2026.

How does a cell reorganize its own molecular machinery to survive a different energetic regime? Working with yeast under carbon limitation, this project follows proteome allocation as resources change — the same logic as the cave, at the scale of a single organism. A manuscript is in preparation.

06Technical Profile

My training spans cultivation-based microbiology, environmental sampling, microscopy, and morphotype characterization from fieldwork in subterranean systems, together with cell physiology and continuous-culture workflows developed at Purdue.

On the quantitative side I work in R and Python for biological data analysis and visualization, use QGIS for spatial and environmental data, and keep reproducible, literate workflows with LaTeX and Git — progressively integrating formal methods with the natural history that motivates them.
