Laura Gomez-Consarnau

Postdoctoral researcher

Nathan Ahlgren

Postdoctoral researcher

ahlgren[@]usc.edu

Research Interests:

I am interested in characterizing interactions between marine bacteria and protists. My researches includes investigating how protist predation (grazing) alters community composition as well as looking for novel mutualistic interactions between bacteria and protists. I am using both whole community approaches enabled by 16S rRNA tag sequencing and single-cell approaches.

Lyria Berdjeb

Postdoctoral researcher

Research Interests:

I am interested in aquatic biological sciences with a focus on the microbial food web functioning. One of my main research objectives is to analyze the relative importance of both bottom-up (i.e., nutrient and autotrophic activity) and top-down (i.e., viral lysis, grazing by flaggellates) forces in driving the dynamic composition of prokaryotic communities in marine systems, by using either ecosystemic or experimental approaches.

Research interests:

I am interested in marine bacterial community interactions with their environment, focusing on how a community responds to changes in nutrients, competition and grazing pressure.  My current research interests are on the potential of marine bacteria to utilize alternative sources of required nutrients.  In addition, I am interested in understanding the interactions between marine bacteria and grazers.

Research interests:

I'm interested how viruses structure marine microbial communities. To this end, for my current research we have undertaken multiple, extended daily time-series at both the SPOT time-series location and near Catalina Island at various times of the year and contrasting environmental conditions. I tend to characterize the microbial communitis using DNA sequencing approaches using marker genes that are almost universal for most cellular life to more specific assays which target, for example the T4-like-myoviruses and the SAR11 group. This research allows us to understand how various groups of microbial communities might be influenced by the environmental conditions and other microbial interactions, including viruses, allowing us to consider bacteria-virus dynamics within the context of widely-discussed hypotheses such as the "Kill-the-Winner" hypothesis. 

I’m interested in investigating virus community spatial biodiversity and temporal diversity using molecular markers and techniques such as TRFLP, qPCR, and DNA sequencing.
How do viruses shape or interact with the microbial community and, thus, influence ecosystem function?
Determine the extent to which the ‘viral-shunt’ may influence biogeochemical cycles in the marine environment.
