<span style="font-size:11.5pt;font-family:"Arial",sans-serif;color:#333333">I am advertising two postdoctoral opportunities available through the National Research Council (NRC) program at the NIST Center for Neutron Research (NCNR). The program is described
at </span><a href="https://www.nist.gov/iaao/academic-affairs-office/nist-nrc-postdoctoral-research-associateships-program">https://www.nist.gov/iaao/academic-affairs-office/nist-nrc-postdoctoral-research-associateships-program</a>.<span style="font-size:11.5pt;font-family:"Arial",sans-serif;color:#333333">
The neutron scattering group at the NCNR is strongly collaborative and the successful candidate will have a great deal of independence and intellectual freedom as well as a generous stipend ($72,000). Online applications for the NRC are open December 1st
and end February 1st. US Citizenship required. <b>Interested applicants should contact</b>

Bayesian model selection approaches to diffraction and inelastic data. For example, can we automatically detect the space group from powder diffraction data? Where do we measure to distinguish between two magnetic Hamiltonians? The ideal applicant would
have a background in science and interest/experience with ML/AI. For example, suppose you are in condensed matter (experiment or theory) and are thinking of getting into ML. I’m also open to those with more of a CS/ML background who want to apply their skills
to a problem in physics.<o:p></o:p></span></p>
