Project Description: 

We seek a Biophysicist/Biochemist or Physicist to work on Small Angle
Neutron Scattering (SANS) and neutron reflectivity analysis of virus
structure and function. Arthropod borne viruses (arboviruses) are
transmitted by blood sucking insects and cause some of the most
devastating diseases known to human and veterinary medicine. Sindbis
virus is prototypic of the arboviruses. Its structure is complex,
comprising two nested icosahedral shells separated by a lipid membrane
that protects a core of single-stranded RNA. Cellular interaction and
infection involves dramatic reorganization of the virus surface and
interior and in appearance of the lipid bilayer. These transitions can
be duplicated by exposure to acidic pH. The aim of the project is to
characterize these dynamic changes in solution and during membrane
surfaces interactions with a series of neutron scattering and
reflectometry experiments that employ contrast variation and modeling.
The ultimate goal is to elucidate the infection mechanism of Sindbis
across several levels of complexity. 

The candidate should be proficient in conducting all aspects of
experimental scattering and analysis, data reduction and modeling.
Previous work in either neutron or X-ray scattering is desirable. 

Qualifications: Ph.D. degree required in Physics, Chemistry or Life
Health and Medical Sciences. Applicants cannot have received the most
recent degree more than five years prior to the date of application and
must complete all degree requirements before starting their appointment.
