Dr. Ryan Murphy

Rhodia - Sr. Scientist II


My expertise is in polymer and nanoparticle physics, primarily in characterization of charged systems. My thesis was geared towards understanding the dynamics of charged systems, with a focus on understanding the translocation physics of polyelectrolytes through protein pores. My postdoctoral work was to understand interfacial adsorption and diffusion of polyelectrolytes and nanopatterned surfaces, as well as measuring nanoparticle dynamics and aggregation kinetics.

Currently, my focus is on scouting new technologies to fill the technical pipeline. I’m involved in developing novel organic and inorganic systems for a variety of applications. Primary objectives involve bench level lab work, advising student research projects, patent/IP mapping, and expanding the external collaborative network of the lab.


Characterization background — Dynamic light scattering (DLS), Small angle x-ray scattering (SAXS), Atomic force microscopy (AFM), conducting atomic force microscopy (CAFM).

Exposure to: Raman spectroscopy, IR spectroscopy, Scanning electron microscopy (SEM), Focused-Ion beam microscopy (FIB), transmission electron microscopy (TEM).

Synthesis - carbon nanotube functionalization, polymer, polyelectrolyte.
