Felix Elling

Felix Elling

Post-Doctoral Fellow
Pearson Group

Felix is a microbial biogeochemist studying the lipid "fingerprints" of archaea and bacteria ‒ microorganisms that control the cycling of elements such as carbon and nitrogen on our planet. His research focuses on reconciling microbiological lab experiments with geochemical observations from the modern ocean to improve the application of microbial lipids for the reconstruction of past environments.… Read more about Felix Elling

Jenan Kharbush

Jenan Kharbush

Post-Doctoral Fellow
Pearson Group

Jenan is a microbial biogeochemist and oceanographer interested in the important connections between microbial ecology and marine biogeochemical cycling.

Originally from Wisconsin, Jenan obtained a B.A. in biology and chemistry from Ripon College in Ripon, WI. Subsequently she earned her PhD from Scripps Institution of Oceanography in La Jolla, CA, studying chemical oceanography in the lab of Dr. Lihini Aluwihare. Her thesis research focused on the use of molecular signatures to investigate microbial metabolic diversity and function in marine environments, and specifically targeted two important classes of microbial lipid biomarkers: bacterial hopanoids and intact polar diacylglycerols.… Read more about Jenan Kharbush

Nagissa Mahmoudi

Nagissa Mahmoudi

Post-Doctoral Fellow
Pearson

Nagissa is broadly interested in microbial degradation of organic compounds including anthropogenic pollutants as well as natural organic matter. Nagissa completed her  B.Sc. in Integrative Biology from the University of Toronto in Canada. Subsequently, she earned her PhD at McMaster University in Canada where she employed a variety of tools, ranging from isotope geochemistry to high throughput sequencing, to investigate microbial communities in petroleum impacted environments. This research involved assessing microbial carbon sources using natural abundance radiocarbon analysis of lipid biomarkers and subsequently linking degradation to specific taxonomic groups. … Read more about Nagissa Mahmoudi
