2011 M.T. Thomas recipient selected

EMSL honors Ajay Karakoti for outstanding postdoctoral achievement

       Ajay Karakoti

Ajay Karakoti will receive the 2011 M.T. Thomas Award for Outstanding Postdoctoral Achievement at EMSL.

He will accept the award at a ceremony Aug. 29 at 3:30 p.m. PDT, in the EMSL Auditorium. Karakoti will give a presentation on his work at that time, and a reception will follow.

Karakoti garnered the honor in recognition of his “insightful and creative contributions to the visualization of functionalized nanoparticle surfaces,” said Robby Robinson, chair of the award selection committee.

The committee noted Karakoti demonstrated EMSL’s interdisciplinary research focus by applying his scientific inquiry to biology, toxicity, materials science, chemistry, and physics by the careful and meticulous characterization of nanomaterials.

“Ajay’s research stands as a perfect example of EMSL’s vision of scientific innovation through integration,” said Interfacial Spectroscopy Technical Group Leader Theva Thevuthasan, who nominated Karakoti for the award. “He combines his fundamental knowledge in chemistry, with first principle calculations to solve a materials science problem of relevance to the biomedical applications. He is not only fundamentally strong but also a great team player and a mentor, a hallmark for an emerging leader in the scientific community.”

Karakoti further impressed the committee with his scholarly productivity. He has co-authored six publications in high-impact journals and presented scientific results at five conferences. The committee also recognized Karakoti for serving as mentor in the Science Undergraduate Laboratory Internship program. According to Scientist Brian Thrall, PNNL Biological Sciences Division, Karakoti has served an important role at the laboratory by mentoring students and postdocs.

The award committee praised Karakoti for his collaborations with EMSL users. Professor Dean Sayle of Cranfield University, United Kingdom, noted Karakoti’s advances and contributions in unraveling nanoparticle interaction mechanisms have built a critical foundation to further guide the application of nanomaterials to medicine and necessarily toxicity.

Karakoti has been a post-doctoral fellow in EMSL’s Interfacial Spectroscopy and Diffraction group since 2010 after completing his doctorate.

He received his doctorate in materials science and engineering from the University of Central Florida, Orlando, under the guidance of Dr. Sudipta Seal. Karakoti holds a Master of Technology in corrosion science and engineering from the Indian Institute of Technology, Bombay, India, and Master of Science in organic chemistry from the University of Delhi, India.

EMSL presented the first MT Thomas award in 1996 in honor of Dr. M. Tom Thomas, who joined the EMSL project team in 1987 and served in various leadership capacities as the project progressed from conceptualization to realization. Thomas served as the EMSL project manager from 1989 to 1991, and was the EMSL operations manager before retiring in 1995.  The award acknowledges outstanding accomplishments by postdoctoral fellows who conduct their research at EMSL.

In addition to Robinson, the other members of the award selection committee are EMSL scientists Mark Engelhard, Ravi Kukkadapu, Vlad Petyuk, Hubertus Van Dam and Tamas Varga.
