Welcome

About Me

Dr. Daniel Muthukrishna is a postdoctoral researcher at the Massachusetts Institute of Technology (MIT). He received his PhD in Astrophysics from the University of Cambridge in 2021. Daniel grew up in Brisbane, Australia, and earned a Bachelor of Engineering (Electrical & Aerospace) and a Bachelor of Science (Physics) from the University of Queensland, Australia.

Daniel’s research primarily focuses on applying machine learning to astrophysical time-series data. His work ranges from modeling supernovae to classifying exoplanets using deep learning and Bayesian methods. Daniel has developed widely used software packages to classify, model, and perform anomaly detection on large datasets.

At MIT, Daniel works with the Transiting Exoplanet Survey Satellite (TESS, a NASA space telescope) team and is leading the effort to classify exoplanets with neural networks. He is also leveraging state-of-the-art machine learning methods, including diffusion models, transformers, and recurrent neural networks to better understand the universe.

Daniel lectures a public course on “Data-Driven Astronomy: Machine Learning and Statistics for Modern Astrophysics”, and supervises several students. He presents lectures at public and academic venues.
