Research Interests
My current research interests include the following topics:
  1. Probing the pathways and kinetics of the reactions of atmospheric trace species with biogenic Criegee radicals
    The primary goal of this research is to gain an understanding of the oxidation mechanism of the atmospheric pollutants by the Criegee radicals derived from large biogenic alkenes in the troposphere. While the simplest Criegee radical CH2OO could be detected and tested in the laboratory, the detection of larger Criegee radicals and direct measurement of their reactions with the atmospheric trace species still remain unexplored. These direct measurements are crucial as the reactions of complex biogenic alkenes derived Criegee radicals are more relevant to the forested regions than those of the smaller Criegee radicals. We would like to set up time resolved Infrared spectroscopic technique to perform direct studies of the reactions of large Criegee radicals which have been challenging so far. While the nature of the work in my research group would be largely experimental, the current research interest on Criegee radicals also deals with the computation of reaction mechanisms and the application of theoretical kinetic methodologies on atmospherically relevant reactions of Criegee intermediates.
  2. Evaluation of the fluorescent molecular rotor properties of Thioflavin T derivatives for use as sensors of Amyloid Fibril/DNA in microfluidic devices.
    Amyloid fibrils are insoluble protein aggregates that are associated with neurodegenerative diseases such as Parkinson’s disease (PD) and Alzheimer’s diseases (AD). Detection of amyloid fibril formation is a crucial step in the identification of these disease states. Thioflavin T (ThT), a benzothiazole-based small molecule is widely used for the detection of amyloid fibril formation in vitro based on its fluorescence intensity enhancement upon binding to amyloid fibrils. However, ThT is a charged molecule and does not cross blood-brain-barrier (BBB). This project involves investigating the properties of various derivatives of Thioflavin T. We plan to study the fluorescent molecular rotor (FMR) properties of ThT derivatives by using steady state fluorescent techniques and computational tools. FMR property is crucial for a compound’s ability to work as sensors for amyloid fibrils. We also plan to test the feasibility of these molecules to work as sensors of DNA and amyloid fibril that can be used in microfluidic devices. Execution of this project involves collaboration with Dr. Bani Kanta Sarma from SNU and Dr. Vitali Stsiapura from Yanka Kupala State University, Belarus.
  3. Probing chemistry at ultra-cold temperatures inside the Helium droplets using Infrared Spectroscopy.
  4. High Resolution Microwave Spectroscopic Study of Molecular Systems of astrophysical Significance by Chriped Pulse Broad Band Microwave Spectroscopy.

Executive Summary
Dr. Goswami did her Masters in Chemistry from Indian Institute of Technology, Guwahati and PhD in Physical Chemistry from the Department of Inorganic and Physical chemistry, Indian Institute of Science, Bangalore. Her thesis work is based on the microwave spectroscopic studies of structure and dynamics of weakly bound hydrogen bonded complexes of water and hydrogen sulfide with aliphatic and aromatic hydrocarbons using a home-built Pulsed Nozzle Fourier Transform Microwave Spectrometer. After completing her PhD, she moved to the University of Hawaii at Manoa (UHM), USA for her first postdoctoral work, where she worked on the reaction dynamics of bimolecular reactions relevant to combustion process using crossed-beam scattering technique. After a year of stay at UHM, she moved to the University of Virginia as a postdoctoral research associate, where she worked on developing and building a Helium Droplet Isolation instrument for studying ions inside Helium Nanodroplets. Dr. Goswami plans to apply the experimental and computational tools to address different problems in the area of atmospheric chemistry, biophysical chemistry and fundamental areas of chemical physics. Her current research interest is aimed towards the understanding of the oxidation process of trace gases in the atmosphere by biogenic Criegee radicals and its role in aerosol formation. Her other research interest is focused on developing sensors for DNA/amyloid fibrils based on Fluorescent Molecular Rotors. Dr. Goswami is also interested to apply spectroscopic techniques to explore fundamental areas of chemical physics such as intermolecular interactions and the reactions at ultra-cold temperatures. .
