CEE Ph.D. student awarded NASA Earth and Space Science Fellowship

CEE Ph.D. pre-candidate Abhishek Chatterjee was awarded a NASA Earth and Space Science Fellowship (NESSF).| Short Read

Abhishek Chatterjee, who works with Dr. Anna M. Michalak, was selected based on his outstanding academic record, and his research proposal entitled “Geostatistical Data Assimilation for the Orbiting Carbon Observatory.” Abhishek’s work focuses on developing sophisticated numerical approaches to mine massive remote sensing datasets for information about both the human and natural components of the Earth’s carbon cycle. Identifying and quantifying the processes controlling emissions and uptake of carbon dioxide is critical to predicting future changes to the climate system. The NESSF program is a highly competitive award for graduate students, valued at $90,000 over three years. Congratulations Abhishek!

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
