Dr. Tomko completed his graduate studies in pharmacology at the University Of Pittsburgh School Of Medicine’s Drug Discovery Institute, where he became familiar with modern drug discovery and development. His thesis work probing the regulation of a short-lived protein sparked his interest in the cell’s machinery to recycle damaged or unneeded proteins. To pursue this interest, he moved to Yale University, where he was an American Cancer Society Postdoctoral Fellow in the Department of Molecular Biophysics and Biochemistry. As a postdoctoral fellow, Robert made several seminal discoveries regarding the assembly of the proteasome, a large, multisubunit protease complex that executes most of the cell’s regulatory and quality control protein degradation. In 2015, Dr. Tomko joined the faculty of Biomedical Sciences at FSU, where his group studies the structure and function of ubiquitin-proteasome system components in normal and disease states. His laboratory works on the scale of individual proteins up to whole cells, and integrates approaches spanning biochemistry, cell biology, genetics, structural biology, proteomics, biophysics, and pharmacology. Ultimately, his group aims to utilize the information gained from these basic studies of the ubiquitin-proteasome system to identify new targets and develop pharmacological modulators with potential thereapeutic benefit.
