Haverford College invites applications to our available full-time, exempt, fixed term (18 months), benefit-eligible Postdoctoral Investigator in Marine Transcriptomics.

The initial appointment is for one year and continued funding is available for an additional 6 months contingent upon satisfactory progress.

The Postdoctoral Investigator will work in the laboratory of Dr. Kristen Whalen, Assistant Professor in the Department of Biology, to investigate phytoplankton-viral dynamics in response to marine infochemicals. For more information about the lab’s research interests, see https://kristenwhalen.weebly.com/. Research in the Whalen Lab at Haverford College has demonstrated marine bacteria are capable of directly interfering with viral lysis of phytoplankton hosts via chemical signals. The focus of this newly funded project will reveal the molecular mechanisms by which the globally relevant phytoplankton, Emiliania huxleyi, evades viral mortality when exposed to the bacterial signaling molecule, 2-heptyl-4-quinolone (HHQ). The postdoctoral investigator will establish a framework for how HHQ modifies viral and host transcript expression during early stages of viral infection. These experiments will mechanistically connect the influence of a bacterial quorum sensing molecule on viral infection and contribute to defining the role of bacterially derived signals that influence the viral shunt.

Support is provided for both workshop travel and career development. We enthusiastically encourage individuals from backgrounds that are underrepresented in STEM fields to apply for this opportunity.

Essential Functions and Primary Responsibilities
We examine marine symbiosis through the lens of small molecule chemical messengers that shape communities and influence the biogeochemical fate of oceanic nutrients. Our lab elucidates the chemical signals that mediate phytoplankton-bacteria interactions and deciphers the environmental drivers of these interactions. Working with our model marine phytoplankton, Emiliania huxleyi, we are teasing apart the metabolic landscape that defines this model host-bacterial symbiosis and detail how and when chemical messengers induce host metabolic reprogramming resulting in ecosystem level consequences, including protection from viral-induced mortality.
