Two PNNL postdocs accept faculty positions
Dr. Emrah Ozensoy
Congratulations to two PNNL postdocs, Emrah Ozensoy and Jose Herrera, who will soon move to faculty positions.
Dr. Emrah Ozensoy
Dr. Emrah Ozensoy, a postdoctoral fellow working with Chuck Peden, has accepted a faculty position in the chemistry department at Bilkent University in Turkey.
Emrah received a B.S. in Chemistry (summa cum laude) from Bilkent University in 1999 and, supervised by Professor Wayne Goodman, a Ph.D. in Chemistry from Texas A&M University in 2004. Emrah was awarded with American Vacuum Society's Morton M. Traum Award, AVS Graduate Research Award and Celanese Chemicals Outstanding Graduate Student Award. He joined the Peden group at PNNL in 2004.
Emrah's research at PNNL involves design, synthesis and characterization of mixed-oxide model catalyst surfaces for NOx Storage Reduction (NSR) systems that are used in the abatement of diesel engine emissions. By developing a bottom-up synthetic strategy, a well-defined model NOx storage system consisting of BaO nanoparticles (active phase) and θ-Al2O3/NiAl(100) ultrathin films (metal-oxide support) were prepared. Chemistry of environmentally relevant molecules such as NO2 and H2O were examined on the BaO/θ-Al2O3/NiAl(100) and θ-Al2O3/NiAl(100) surfaces by utilizing various surface scientific probes. In addition, these results are compared with realistic high surface area NOx storage materials (e.g. BaO(20 wt%)/γ-Al2O3).
At Bilkent University, Emrah plans to continue research in surface chemistry, focusing on the chemistry and the structure of atomistically well-defined metal and metal oxide surfaces in relevance to heterogeneous catalysis. In particular, he intends to pursue in-situ spectroscopic studies on gas/solid interfaces over a pressure range from ultra-high vacuum to 1.0 atm in order to bridge the pressure gap between surface science and industrially relevant conditions.

Jose E. Herrera
Jose E. Herrera leaves PNNL in early 2006 to take up a position as assistant professor in the department of chemical engineering at the University of Western Ontario in Canada.
Jose received his BSc degree in Chemistry from the Pontificia Universidad Catolica del Peru. In 1997 he graduated summa cum laude of his class and took a job in an environmental regulation agency of the Peruvian government. A year later he was granted a Fulbright scholarship and enrolled at the University of Oklahoma where he received his PhD degree in Chemical Engineering under the supervision of Prof. Daniel Resasco. His doctoral research was focused on the mechanism of single-wall carbon nanotubes (SWNT) growth over a bimetallic CoMo catalyst. In 2004 he joined PNNL as a postdoctoral fellow in Chuck Peden's group where he has worked on a DOE-BES project related to the synthesis and tailoring of early transition metal oxide clusters for catalytic applications.
To launch his research program at the University of Western Ontario, Jose plans to continue research on carbon nanotubes and heterogeneous catalysis.
