Alexander Gaeta, the David M. Rickey Professor of Applied Physics and of Materials Science and Professor of Electrical Engineering, is the recipient of the 2019 Charles Hard Townes Award from The Optical Society (OSA). Gaeta is recognized for seminal contributions to chip-based nonlinear photonics, nonlinear optics in photonic crystal fibers and nonlinear propagation of ultrashort laser pulses. “Technologies emerging from basic research in quantum and nonlinear photonics can be traced in many instances to the achievements of Alexander Gaeta,” said 2019 OSA President Ursula Gibson. “For more than 2 decades, his discoveries and inventions have been a driving force in the quantum revolution unfolding from advances in optics and photonics.”
Latha Venkataraman, a Professor of Applied Physics and Chemistry, has been named the Lawrence Gussman Professor of Applied Physics Chair (effective July 1, 2019). She joined Columbia University as a research scientist in 2003 and started her independent career as an assistant professor in the APAM Department in 2007. Prominent awards she has received include the National Science Foundation Career Award, Packard Fellowship for Science and Engineering, and the Alfred P. Sloan Fellowship in Chemistry.
Scientists expect climate change to increase America’s propensity for warm moist air, which should mean more thunderstorms and tornadoes. Wind speeds should stay the same, but tornado patterns are too small to explore deeply in the global computer models meant to simulate huge sections of the planet. “There’s a lot of interest nowadays in how climate change is going to affect aspects of weather, especially extreme weather — whether it’s droughts, heat waves, floods or hurricanes,” said Prof. Michael Tippett, adding that if you had to rank where the scientific research is certain or uncertain, tornadoes sit at the top of the uncertainty list.

Research from Latha Venaktaraman's group was recently published in the artcile, "Non-chemisorbed gold–sulfur binding prevails in self-assembled monolayers," in Nature Chemistry. Improved mechanistic understanding will help answer the question of how predominantly chemisorbed sulfur-gold SAMs can be reliably formed under ambient conditions, if at all. This will help focus efforts to identify new linker groups, and/or preparation methods, that facilitate the construction of more stable SAMs with increased electronic transparency and stability. The effect of surface pre-treatments on the molecule-substrate bonding of gold-thiol SAMs is likely also a rich area of further study/reinterpretation.
Simon Billinge, a Professor of Materials Science and Engineering and Applied Physics and Applied Mathematics and a Scientist at Brookhaven National Laboratory, and APAM alumn, Dr. Chenyang Shi (Ph.D. 2015, Materials Science and Engineering), were recently featured in the following article by Mary Alexandra Agner. It was originally published as highlight on the Advanced Photon Source/Argonne National Laboratory website.
