Alok worked at the Materials Research Institute at Penn State. He was studying the properties of 2D materials and learning the various methods to characterize them. He is using high-temperature vacuum furnaces to grow InSe, GaSe thin layers on Epitaxial Graphene. To study their properties he was using Scanning Electron Microscopy, Atomic Force Microscopy, Raman Spectroscopy etc.

I was involved in the project HELIX (High Energy Light Isotope eXperiment). It is a balloon-borne experiment designed to measure the chemical and isotopic abundances of light-cosmic ray nuclei from ~200 MeV/nucleon to ~10 MeV/nucleon. It is expected to fly in Antarctica in December, 2020. I tested the Silicon Photomultipliers which are used in fabrication and testing of the time-of-flight detector systems. The IV characteristics were made to know about their operating voltage. Thermistor calibration and vacuum testing were done to know their behavior. SiPM assembly was mounted on scintillator bars for the assembling into the overall HELIX instrument.”
Richa is researching the synthesis and characterization of 2D materials. She will be using high temperature vacuum furnaces to grow GaSe thin film. And, then she will characterize the grown materials using Atomic force microscopy, Raman Spectroscopy and Photoluminescence spectroscopy she will characterize these materials and their opto-electronic properties.
Soumi researched on “Speech deterioration in Alzheimer’s Disease”. She collected speeches and literary articles of politicians, author and other celebrities who had Alzheimer’s. After which she was applying Machine Learning Algorithms to these texts to help the machine learn about the statistical trends in the speeches of these celebrities over the years of their life. The deterioration can be in the form of loss in memory resulting in stammering speeches. or increased used of fillers, or increased used of pronouns or some trend in the use of the various parts of speeches etc. All these factors will be taken into account to slowly answer their research questions.
