Chowdhury awarded $1M AFOSR grant to study materials in extremes

Assistant Professor Enam Chowdhury and his team of engineers and physicists have been awarded a $1.056 million grant from the Air Force Office of Scientific Research.

The team will investigate how materials excited by intense laser fields behave on time scales as short as 1 femtosecond (1/1000 of a trillionth of a second) and on spatial scales as small as that of an atom using next-generation, near-single-cycle-pulse and various other laser sources and ultrafast scanning tunneling microscopes (STM).

State-of-the-art high-performance computing will be used, including new algorithms developed by the Femto-Solid Laboratory to predict and explain the experimental results.

Enam ChowdhuryChowdhuryThis fundamental research on extreme laser material modification and damage can be highly controlled when ultra-short time duration laser pulses are used. Such research has had a large impact on society by advancing material processing, modification, surface engineering, opto-electronics and photonics, measurement, manufacturing and surgery.

Chowdhury is an assistant professor in the Departments of Materials Science and Engineering, Electrical and Computer Engineering, and Physics. Members of the team include Professors Douglass Schumacher and Jay Gupta from the Department of Physics and Alok Sutradhar from the Department of Mechanical and Aerospace Engineering.
