Work History

Research Assistant

New Jersey Institute Of Technology
8 2023 - Current

Working under Dr. Alexander Kosovichev (NJIT) and Dr. Viacheslav M Sadykov (GSU)

  • Analyzed solar spectropolarimetry data and X-Ray data associated with sunquakes from SDO, Hinode, IRIS, GOES, and Konus-Wind satellites
  • Analyzed SDO HMI observations of Fe I 6173 Å line reversal during solar flares due to particle beam heating above sunspot umbrae
  • Created shared Jupyter Notebooks for easy analysis of data by collaborators
  • Repaired and upgraded daily data upload pipeline for the NJIT SolarFlare MySQL database
  • Designed and constructed a 3D-printed spectrograph to observe the Fe I 6374 Å coronal line during the 2024-04-08 total solar eclipse

Research Intern

NASA Ames Research Center
06.2021 - 08.2023
  • Worked on Stellar Jitter project under Dr. Irina N. Kitiashvili
  • Generated synthetic observations of target planet-host star HD121504
  • Estimated absolute stellar abundances for iron by comparing synthetic and observational spectral iron line profiles
  • Greatly improved efficiency and ease of use of computational pipeline through use of IDL, Python, and CSH scripts
  • Wrote number of post-processing scripts in Python to compute observables from synthetic data
  • Obtained observables using synthetic data to characterize stellar jitter including disk integrated profiles, time-series data spanning many hours, and doppler velocities
  • Prepared graphs and images for visualization of observables
  • Presented poster on Stellar Jitter project in Universities Space Research Association (USRA) symposium (August 2021)
  • Gave regular presentations on personal accomplishments within Stellar Jitter project to USRA
