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:

Images of Faint Star Galaxy QSO Image

Star - Galaxy - QSO Image Classification

Under the guidance of Prof. Ajit Kembhavi, Dr. Vivek M. and Dr. Kaushal Sharma, we used 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.

Light Curve Example

Photometric Classification of Simulated LSST Light Curves

As part of a team, we developed a solution for the PLAsTiCC challenge. Our stacked ensemble of GRU and Dense networks was trained on 7878 light curves and achieved an accuracy of 76.2% on a test set consisting of over 2.5 million light curves.


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