The Ecological Genomics Group explores the roles, evolutionary dynamics, and interactions of marine microbes. We integrate genomic, imaging, and physiological methods to connect the vast unknown microbial diversity in the ocean with their functional roles in marine ecosystems.

Our group leverages multi-omic and molecular biology approaches to uncover the genetic potential of natural microbial communities and link it to the processes driving key biogeochemical cycles.

Two core objectives guide our research:

  1. Developing genomic and metagenomic methods to generate testable hypotheses from complex omics datasets.

  2. Applying multi-omics and advanced imaging techniques to investigate the evolution and interactions of often-overlooked marine bacteria.

Ecological and Evolutionary Role of Specialized Bacteria in Algae Health and Carbon Sequestration – ERODERS

ERODERS focuses on previously unaccounted-for bacteria capable of degrading recalcitrant organic carbon—complex compounds derived primarily from algal structures and exudates. We hypothesize that these specialized bacteria, integral members of the algal microbiome, feed on complex glycans and have co-evolved with algae. Their activity may play a key role in maintaining host health and modifying polysaccharide structures that contribute to long-term carbon sequestration in the ocean.

We are happy to announce that Tomás Sauma is starting his PhD with us! He will combine genomic and visualization approaches to determine the diversity and spatial location of specialized bacteria living on algae. He will also use computational methods to understand genome size and evolution in bacteria. Good luck!

C. Belén Pareja is joining our group for six months! She is a PhD stu­dent from Rodrigo De la Ig­lesi­a's Lab­M­ic­Mar group in Chile. She stud­ies mi­cro­bial com­munit­ies in mar­ine epi­lithic biofilms, spe­cific­ally in the rocky in­ter­tidal en­vir­on­ment of Cent­ral Chile. "Who is where and when?" and "What are they do­ing?" are some of the ques­tions she is try­ing to an­swer. She won an ANID schol­ar­ship that funds her stay and re­search here. Good luck!
