 Group Members

Joel D. Brock, Ph.D. (email)

Joel is a Professor in the School of Applied and Engineering Physics and a member of the graduate fields of Applied Physics and of Materials Science and Engineering. He is a principal investigator of both the Dynamics of Growth of Complex Materials and the Controlling Complex Electronic Materials interdisciplinary research groups of the Cornell Center for Materials Research. Joel is Director of the G-Line division of the Cornell High Energy Synchrotron Source (CHESS) and is leading the x-ray beam line development effort for the Energy Recovery LINAC project. He received his Ph.D. in physics from the Massachusetts Institute of Technology in 1987 and came to Cornell in 1989.

Postdoctoral Research Associates

Yongsam Kim, Ph.D. (email)

Yongsam received his Ph.D. from Gwangju Institute of Science and Technology, South Korea. He is now a Post-Doc currently working on x-rays studies of complex oxide materials.

Peter Ko, Ph.D (email)

I obtained Ph.D. in chemistry at the University of Western Ontario, London, ON, Canada, under the supervision of Professor Tsun-Kong Sham. Focus of my research was on analysis of light-emitting materials by X-ray Absorption Fine Structure and X-ray Excited Optical Luminescence.

In the fall of 2010, I ventured across the border and arrived at Cornell. Here, my focus of my research is on application of high-energy X-ray diffraction for time-resolved structural studies of electrochemical and catalytic processes of solid interface. In order to achieve this goal, I, along with number of collaborators at Cornell and CHESS are working on deploying high energy X-ray micro-diffraction capabilities at CHESS to characterize in-situ and real-time atomic structure of novel materials, interfaces, heterostructures, and processes associated with fuel cells.

Manuel Plaza, Ph.D (email)

I received my Ph.D. in physics from Universidad Complutense de Madrid (Spain) in 2009. My research was focussed on the electrodeposition of nanomaterials with exceptional magnetotransport properties. After a postdocotoral stay at Universidad Autonoma de Madrid (working in Photoemission Spectroscopy and X-ray Surface Difraction), I joined to the Professor's Brock Group to study different electrochemical process using X-ray based techniques.

Graduate Researchers
Timur E. Babakol (email)
Timur is a Graduate Student in the School of Applied and Engineering Physics. He is currently working on the nucleation process and coarsening kinetics that occur between laser pulses in PLD.
Xin Huang (email)
I am a Graduate Student in the School of Applied and Engineering. I am now working on X-ray study on electrochemical growth.
Undergraduate Researchers
Andy Siliciano (email)
Andy is a senior in the School of Applied and Engineering Physics. He is currently working on plume dynamics for pulsed laser deposition.
Xinyue Fang (email)
I'm currently working on finding the correlation between temperature and oxygen vacancy concentration. The goal of my project is to be able to create sample with well defined vacancy concentrations.
