Fredy Zypman, Ph.D. is a professor of applied physics at the Katz School of Science and Health. He received his degrees in Uruguay (B.S. in Engineering), Venezuela (License in Physics) and USA (Ph.D. in Applied Physics). Before joining Katz School of Science and Health at Yeshiva University, he taught for many years at the University of Puerto Rico. In addition to his work in academia, he has consulted on instrumentation for the medical and energy industry.
Current Areas of Study
- Quantum Transport: Theoretical studies of electronic transport through quantum structures
- Friction: Experimental studies of stick-slip and its relationship to Self-Organized Criticality.
- Defects in Solids: Generalizing Equivalent Crystal Theory to evaluate defect formation energies.
- Colloids: Theoretical studies to obtain interactions between particles and surfaces in aqueous solutions.
- Viscosity: Reconstruction algorithms to extract oil viscosity from Atomic Force spectroscopy.
“We’re at a very primitive stage of understanding the charge content of very small systems. Proteins, nanoparticles—we’re talking about systems that are 10,000 to 100,000 times smaller than the thickness of a hair. People commonly use 100-year-old techniques to measure charges in systems like this." — Dr. Fredy Zypman
