Appointments August 2008 – August 2011 Research Scientist, (30% time) University of Geneva (Prof. Jacques Schrenzel,MD and Prof. Patrice Francois, PhD, Genomic Research Lab)

Sept. 2011- August 2014 Post-doc/Adjunct Faculty, San Diego State University (Prof. Forest Rohwer, PhD)
I am a biochemist interested in human associated microbial and viral communities. I use metagenomics, metabolomics, microbial genetics and ecological statistics to answer questions about how microbes and viruses affect human health. I am interested in understanding how individual and persistent human-associated microbial and viral communities affect health. Infection with a bacterial pathogen, vaccination, immune development and even taking a Tylenol does not occur in a vacuum. Dynamic microbial and viral communities constantly inhabit our bodies, encoding the majority of the unique genes that alter these processes. Resident microbial and viral community composition is unique to each human.

Specifically, I am working to understand the role of persistent microbial colonization in triggering inflammatory episodes in Cystic Fibrosis patients. Understanding microbial interactions and changes in microbial physiology that are associated with changes in patient status may lead to the development of biomarkers to diagnose changes in infection earlier and more specifically.

I am also interested in how phage shape dynamic host-associated microbial communities, and in characterizing the function of the 70% of phage encoded genes with no known function.
