I am an experimental physicist and a research associate atÌýthe National Institute of Standards and Technology (NIST) where IÌýworkÌýwith the . I am also a research associate with the Department of Physics at ÃÛÌÒ´«Ã½Æƽâ°æÏÂÔØ. My research is focused onÌýthe intersection of magnetic materials (especially on micro- and nano- scales), sensing, and metrology.Ìý
I received my BA in Physics (with honors) from The University of Chicago in 2010 and a PhD in Physics from Carnegie Mellon University in 2016. At Carnegie Mellon, IÌýperformedÌýmy PhD work in ProfessorÌýSara Majetich's groupÌýand wrote my dissertation on patterned magnetic nanostructures.
Following myÌýPhD, IÌýwas awarded a National Research Council (NRC) Postdoctoral Fellowship. I performed myÌýNRC fellowship at NIST, Boulder, where I was advised byÌýDr. Gary Zabow. During my postdoc, IÌýresearchedÌýnovel MRI contrast agents and magnetic signal transduction in magnetic nanoparticle/polymer composites.
