Members of Ragan Group

Professor Regina Ragan:

Prof. Ragan received her Ph.D. at the California Institute of Technology working with Prof.  Harry Atwater in 2002. Her Ph.D. thesis involved kinetics and thermodynamics of self-assembled nanostructures - experiment and theory. She then joined the Quantum Science Research group at Hewlett Packard Laboratories as a post doctoral scholar working with Stan Williams. As a post doc she continued her work on self-assembled nanostructures and also studied organic/inorganic interfaces. She has been at UCI since summer of 2004. Please see the research page for current research topics.

Robert Sanderson

Robert received his B.S. in Physics from UC Riverside, where he did ion scattering experiments in Jory Yarmoff's surface science laboratory. An expert in ultra-high vacuum systems, scanning probe techniques, and materials physics, his interests lie in the nanoscale characterization of catalytic materials. He recently defended his doctoral dissertation, titled “Design and Optimization of Nanomaterials for Sensing Applications”.

Adrian Espinoza Garcia 

Adrian is focused on the control of graphene growth in 2D and 3D structures. His current work focues on creating freestanding 3D graphene monoliths from sacrificial templates and modifying the electronic structure of these structures by controlling the number of graphene layers or doping the graphene via chemical vapor deposition. He has previoulsy worked with growing graphene directly onto dielectric surfaces such as SiO2 without the need for a transfer step. In addition, he has also worked on graphene growth from solid carbon sources such as standard photoresists used in the photolithography field. He graduated from UC Merced with a BS in Mechanical Engineering. 

Chen Wang

Chen studies metal nano-catalysts via scanning tunneling microscopy (STM) and density functional theory (DFT). Specifically, she explores tuning platinum and iron nanoclusters supported on doped graphene for water splitter reactions and advanced energy storage applications. Her prior experience with STM and DFT comes from her Master's project at UC Riverside and Aahurs University tuning MoS2 nanoislands for hydrodesulfurization reactions. She graduated from Franklin W. Olin College with BS in Electrical Engineering.

William Thrift

Will Thrift is interested in fabricating plasmonic devices. He uses self-assembly to precisely deposit colloidal nanoantenna onto fixed substrates that greatly enhance the incident electric field of light. He uses the nanoantenna substrates to detect cellular metabolites, small molecules that give researchers insight into gene expression at a particular moment. He integrates this sensor platform with microfluidics to identify bacteria in biofilms. He is also interested in self-assembled plasmonic metasurfaces that enhance the magnetic field of light, produce novel polarizations, and enhance nonlinear effects. He graduated with a degree in nanoengineering from UC San Diego.

Evangeline Wong

Evangeline is a Master's student who is developing theoretical models to predict the mechanical properties of liposomes.

Hong Wei

Hong is interested in developing a new integrated biosensing platform. Currently, she uses theoretical modeling method to study the performance of polymer optical waveguides for integrated Surface-enhanced Raman Spectroscopy(SERS) biosensors. She is also learning the fabrication and deposition of nanoantennas to maximize enhancements of optical signals. She graduated with a BS in Electronic science and Technology from Inner Mongolia University.
