Marina Mulenos George, B.S.

Second-Year PhD Student

Expected Graduation Date: May 2022

Marina Mulenos George serves as a laboratory technician and graduate researcher for The Sayes Group. While pursuing her B.S. in Chemistry, Marina was a research assistant in the Department of Chemistry and Biochemistry at Baylor University. During this time constructed a cold fluidics system for hydrogen/deuterium exchange mass spectrometry. Her interests include analytical chemistry, forensics, nano-toxicology, biomarkers, and clinical toxicology. She is currently conducting a comprehensive physiochemical characterization of microfibrilated cellulose fibers and identifying the physiochemical features of gold nanoparticle-protein corona.  

Marina is a talented laboratory technician and specializes in general analytical instrumentation. Her specialties include mass spectrometry (LC-MS, GC-MS, ICP-MS, MS/MS, HDX-MS), microscopy (Light, Hyperspectral, SEM, TEM, Fluorescence), and dynamic light scattering (PDI, Z-average, Zeta Potential).

Marina is a first-year Nanotoxicology PhD candidate in the Department of Environmental Science at Baylor. She is expected to graduate in May 2022. After graduation she hopes to continue her career as a research scientist either in industry or academia.
