Juleen joined the UW–Madison Department of Biochemistry in August of 2019 as a Postdoctoral Research Associate in the new Cryo-EM Research Center where she is using cryo-ET to investigate eukaryotic cell ultrastructure. She has a broad background in a wide range of scientific techniques. She received her B.S. in Marine Science from Long Island University and her M.S. in Biology at California State University, Fullerton. She earned her Ph.D. in Cell and Molecular Biology at the University of Wisconsin-Milwaukee, where she used transmission electron microscopy techniques to investigate the ultrastructure of plant tissue. During this time, she gained experience with conventional TEM, SEM, and ultramicrotomy and assisted the director of the electron microscopy facility with user training, routine equipment maintenance, and the daily operations of the facility.
