Research

Currently, my research interests are in Astrophysics, Astronomical Instrumentation, and Data Science. Some of my research experiences are shown below.

Light Curve Analysis of a Young Type II-L Supernova

Department of Astronomy & Astrophysics, University of Toronto
May 2021 - Present


  • Currently investigating the BVI observations of a young Type II-L supernova from the KMTNet Supernova Program
  • Analyzed a large dataset of images with Python to determine supernova intensity over time; performed image subtraction, PSF photometry, and filtering of light curves
  • Fit different models to light curves in order to determine the supernova's key physical parameters

DMD-Based Multi-Object Spectrograph

Dunlap Institute for Astronomy & Astrophysics, University of Toronto
May 2020 - Present


  • Currently working on a wavelength calibration fit to correct hyperspectral imaging distortion (smile and keystone distortion) in a digital micromirror device (DMD) based multi-object spectrograph
  • Designed, analyzed, and optimized optical systems with Zemax OpticStudio
  • Used k-means and other methods to fit 3D data in Python; used ZOS-API in MATLAB to efficiently generate simulated optical performance data
  • Created and submitted a poster for the Royal Astronomical Society Early Career Poster Exhibition

Photocatalytic Hydrogen Generation and Solar Reflective Nanofilms

Nanomaterials and Nanosystems Innovation Research Group, Department of Electrical and Computer Engineering, National University of Singapore
May 2019 - August 2019

  • Wrote a Python script to process and convert Type T thermocouple voltage values to temperature values, from an analog-to-digital converter
  • Synthesized TiO2/Ag nanofibres by electrospinning, and experimented with the best combination of reactants to achieve maximal hydrogen generation; worked safely with high voltages (17.5kV) and hazardous substances
  • Used a variety of precison instruments including a scanning electron microscope, gas chromatograph, atomic force microscope, and UV-Vis-NIR spectrophotometer
