Lab news

We are welcoming two new lab members soon. Richard Puxty (from David Scanlan's lab) will start a postdoc this summer, and Alex Chase will begin a PhD in the fall.

Marcie Marston will visit in June.

Jeniffer Pena and Steven Nyugen are graduating in June!

Congratulations to Kristin who received three awards recently: the BioSci Dean's Award at the UCI AGS Symposium for her presentation, the Brython Davis Graduate Fellowship, and the Lake Forest Garden Club Scholarship.

Jeniffer and Sanae presented posters at UCI's UROP symposium. Both posters were selected for display in the administration building.

Looking forward to summer including ISME in Seoul and ESA in Sacramento...

Research Overview


Competition cultures
Our lab studies the generation and maintenance of microbial diversity and its consequences for ecosystem functioning. In the past, we have focused on characterizing patterns of microbial diversity (biogeographic patterns). We are now turning our attention to experimentally testing the evolutionary and ecological mechanisms generating these patterns and whether this variation in microbial composition affects ecosystem functioning.

Bacteria
We study all sorts of microbes such as viruses, bacteria, and fungi in a variety of ecosystems. Depending on the question, we also apply a range of approaches, including experimental evolution, field experiments, and greenhouse microcosms. We often use molecular genetic approaches to characterize microbial diversity (from PCR and cloning to whole genome sequencing and functional metagenomics), with the goal of linking this genetic diversity to phenotypic traits and ecosystem functioning.
