Vikas Kumar

I am a doctoral researcher working on advanced computational analysis of aerosol particles using high-resolution X-ray free-electron laser (XFEL) measurements, with a focus on particle morphology, size distributions, and microphysical properties. I have prior research experience in particulate matter source apportionment using Positive Matrix Factorization (PMF), satellite reanalysis datasets (MERRA-2), and machine-learning approaches for real-time analysis and calibration of low-cost air quality sensors.
