Postdoc in parasite evolution
We are looking to hire a postdoctoral research associate on a 3-year
project on parasite modulation of metabolism.
An astonishing outcome of the antagonistic coevolutionary dynamics between
host and parasite is the evolution of parasite ability to interfere with
host physiology. The molecular details of such interference is poorly
understood, limiting our ability to decipher parasite virulence and
its evolution.
A major component of parasite mediated “host reprogramming” targets
host metabolism and thereby results in improved parasite growth. A
particularly striking example of this is the ability of several viruses
to increase the rate of glycolysis in infected cells by up to 370%. More
elaborate modulations include, for example, the alteration of lipid
and GTP biosynthesis. These findings strongly indicate that a full
understanding of host-pathogen interaction and pathogen-caused disease
states require a holistic view that considers host and the pathogen as
a single system.
This project will concentrate on the interaction of Burkholderia
pseudomallei and Francisella tularensis with human macrophages. Utilizing
metabolic modeling together with phenotypic profiling and flux
measurements, we will achieve a better understanding of how these
parasites manipulate their host and cause disease. The ultimate aim is
to develop better strategies of combating intracellular parasites and
developing robust analysis approaches at the host-parasite systems level.
To apply, please send your CV, covering letter (detailing your motivation)
and the details of three referees to Orkun S. Soyer quoting the job
