Michael Gorbet

mike gorbet

Michael-Joseph Gorbet obtained his Bachelor’s of Science degree in Chemistry in 2016, from Southwestern Oklahoma State University, Department of Chemistry and Physics. During his undergraduate education, he was involved in bioinorganic synthesis chemistry making contrast agents and oxidation catalysts for three years. Gorbet also participated in internships at both Georgia Tech University and the University of Hull, UK.

After a year as a Ph.D. student in the Chemistry and Biochemistry department at the University of Oklahoma, he transferred to Dr. Ranjan’s lab at Oklahoma State University as a National Science Foundation Bridge to the Doctorate Fellow and graduate research assistant. 

Gorbet  is a proficient synthetic chemist working with both organic and inorganic chemistry with a future aim in contributing to making a targeted cancer therapy using a nanoparticle-based delivery system.  Specific areas of current work and research interest include:

  • Nanoparticle synthesis for real-time imaging of immune response
  • Organic/Ligand Synthesis with Metal Complexation for cell-based targeting
  • Device induced nanoparticle synthesis for cancer therapy

Danny Maples
Postdoctoral fellow

Areas of Research: HIFU Guided Drug delivery, Nanoparticle synthesis

Cristina Munteanu, Ph.D.
