Andrea Szakal

Andrea Szakal received her Ph.D. in Chemistry from Penn State University. While at Penn State, she studied the catalytic mechanism and folding pathway of the hepatitis delta virus (HDV) ribozyme in Philip Bevilacqua's lab.She was then awarded an NRC/NIST Postdoctoral Fellowship and worked in John Marino's lab at the Institute for Bioscience and Biotechnology Research (IBBR) (formerly the Center for Advanced Research in Biotechnology (CARB)) where she began investigating the structure of RNA from the HIV-1 genome using a variety of techniques, including fluorescence, NMR, and small-angle neutron scattering. She is currently a Research Chemist and is continuing the work from her postdoctoral appointment, and is interested in expanding upon her work to develop methods for the study of large-RNA structures.
