AI Winter Workshop, Machine Learning

Registration Open: AI Winter Workshop, hosted by the Brown CFPU: Jan. 16-19, 2024

Ariel Green |

We are pleased to announce the upcoming AI Winter Workshop – Brown University, Dept of Physics, taking place virtually January 16 – 19, 2024. Details and registration (open to all) are available our workshop pages: Winter AI Workshop on Indico.

Hosted by the Brown Center for the Fundamental Physics of the Universe, this Workshop will consist of six modules consisting of a lecture session delivered by Brown Physics faculty members, followed by practice workshop sessions for participants with direction in the use of machine learning tools. The Workshop will open with a discussion “What Discoveries and New Techniques will be Enabled by AI?”.

The goal of this Workshop is to offer examples of the direct applications of machine learning methods to a range of problems inspired by the use of artificial intelligence in physics. We will provide hands-on experiences with machine learning tools to help reduce the barriers to engagement with these essential tools for physics research, using examples from astrophysics, high-energy and condensed matter physics.

This Workshop is open to interested graduate students, post-doctoral students and advanced undergraduates from any institution. There is no registration fee, and all sessions and workshops will be conducted virtually over Zoom.

Registration is now open!

Postdoctoral Research

The CFPU welcomes Dr. Shawn Dubey

The CFPU welcomes Dr. Shawn Dubey, who will begin his term as Postdoctoral Research Associate at Brown in September. Dr. Dubey writes, “My research is primarily in particle physics. I study the application of various AI and machine learning methods to search for new physics and rare events in particle physics data. My current focus is on using machine learning for anomaly detection. I previously worked on the Belle experiment, where I searched for rare decays at the Υ(5S) resonance, and the Belle II experiment, where I helped validate the electronics for Belle II’s Cherenkov imaging time-of-propagation (iTOP) sub-detector.” Welcome, Dr. Dubey!

The CFPU welcomes Dr. Madhurima Choudhury, who will begin her term as Postdoctoral Research Associate at Brown in October.

Dr. Choudhury writes, “My research focuses on cosmology, particularly on the 21cm line of neutral Hydrogen. I work on applying machine learning techniques to extract the faint 21cm signal and develop parameter inference methods. A significant part of my research is centered around studying the Epoch of Reionization (EoR), a crucial phase in the Universe’s history when the primordial neutral hydrogen was ionized by early stars and galaxies. My primary interests are, exploring various aspects of the HI 21cm signal, interpreting observations, and developing strategies for detecting the EoR HI signal. My contributions aim to enhance our understanding of this pivotal era and its impact on the evolution of galaxies.” Welcome, Dr. Choudhury!
