Katie Weigandt is a staff scientist at the NIST Center for Neutron Research in Gaithersburg, MD where she uses small angle neutron scattering (SANS) and rheology to develop structure-function relationships in a variety of complex fluids including gels, colloidal suspensions, microemulsions and micellar solutions. Katie is also working with a multidisciplinary group of scientists to develop a new grating based far field interferometer to enable “tomographic SANS” measurements. She earned her PhD in Chemical Engineering in 2012 at the University of Washington, Seattle, an MS in Chemical Engineering at the University of Idaho (2007) and a BS in Chemical Engineering at Oregon State University (2005).
