Dr. Zhaoxi Zheng

Biography

I obtained my Ph.D. in chemistry at Brandeis University under Prof. Klaus Schmidt-Rohr. I have a strong background in solid-state nuclear magnetic resonance (ssNMR) spectroscopy, analytical methods development, and materials characterization. I have a master's degree in polymer science from the University of Akron, and a bachelor's degree in polymer materials and engineering from Donghua University. My research focuses on using advanced ssNMR techniques to quantify and analyze the composition and structure of complex organic materials, such as pharmaceutical solids, hydrothermal carbons, and nanomaterials. I have collaborated with leading companies such as Merck and Firmenich and contributed to nine peer-reviewed publications, one book chapter, and two conference posters. I have also developed and taught undergraduate courses in general and physical chemistry labs and received a career fellowship from the Graduate School of Arts and Sciences. I am passionate about applying my ssNMR expertise and polymer-based materials knowledge to solve real-world problems in various industries, such as pharmaceuticals, microelectronics, and biotechnology. I have hands-on skills in various instrumentation, such as solution-state NMR, X-ray diffraction, GPC, HPLC, Mass, DSC, TGA, Raman, and ATR. I have excellent problem-solving, multi-tasking, interpersonal, collaboration, and communication skills, and I am eager to learn and grow as a professional.
