I'm Siddharth Chaini, or Sid for short. I'm currently pursuing my PhD at the Department of Physics and Astronomy, University of Delaware.

My work is at the intersection of computer programming, data science, physics, and astronomy. I'm particularly interested in:

  • Transients and Time-Domain Astronomy
  • Astrostatistics and Astroinformatics

When I'm not working on research, I enjoy watching and playing football (soccer), coding for fun (automating the boring stuff!), and bicycling.

Key Projects

Here are some highlights of the projects I have worked on:


Light Curve Feature Extraction for RESSPECT

I worked on improving feature extraction methods for RESSPECT. We explored curve fitting approaches and deep learning algorithms (GP-VAE) to extract features from light curves. You can read more about this on the project page here.

Images of Faint Star Galaxy QSO Image

Star - Galaxy - QSO Image Classification

I worked on using deep learning for photometric classification of compact images from the Sloan Digital Sky Survey as galaxies, stars or quasars. You can read more about this work in our paper, here.


While still in early stages, you can check out my blog here!
