Jasmine is a recent graduate in the Biochemistry, Biophysics, and Structural Biology (BBSB) program. She defended on April 21st, 2023. She did her PhD thesis work in the lab of Dr. Andrea Soranno, where she studied how sequence composition of intrinsically disordered regions within a protein can affect interactions with both proteins and nucleic acids using single-molecule fluorescence spectroscopy.
Jasmine joined the BBSB program after receiving her B.S. from Stockton University in Galloway, New Jersey with a major in biochemistry & molecular biology and a minor in holistic health. Prior to starting her Ph.D. work, Jasmine studied polymer synthesis and how polymer interactions contribute to optimized hydrogel formation. (more…)
Ankita did her MS in Medical Biochemistry at Sardar Patel Medical College in India. She joined DRSCB program through the Division of Biology and Biomedical Sciences at Washington University in Saint Louis in 2018 and is pursuing PhD in the lab of Dr. Eric Galburt in the Department of Biochemistry and Molecular Biophysics.
Ankita’s graduate research is focused on characterizing the activation mechanisms of a helicase and DNA repair protein called UvrD1 from Mycobacterium tuberculosis. She is using quantitative assays like analytical ultracentrifugation to determine the oligomeric status and stopped flow kinetics to measure DNA unwinding by UvrD1 in presence and absence of accessory factors.
