About Me

I'm a second-year CMU Physics PhD student working at the McWilliams Center for Cosmology. I'm interested in applying various methods of statistics and machine learning to advance studies in computational and observational cosmology.

Outside of my research, I'm an avid swimmer and an amateur chess player. I'm also a member of the CMU physics department soccer team, Manfred United. You can check out my Github for a comprehensive and up-to-date list of my current projects.

A Robust and Efficient Deep Learning Method for Dynamical Mass Measurements of Galaxy Clusters (arXiv:1902.05950; submitted to ApJ)

We demonstrate the ability of Convolutional Neural Networks (CNNs) to mitigate systematics in the virial scaling relation and produce dynamical mass estimates of galaxy clusters with remarkably low bias and scatter. We present two models, CNN1D and CNN2D, which leverage this deep learning tool to infer cluster masses from distributions of member galaxy dynamics.

Materials Search

Materials Search is a web-scraping and data-mining tool to aid researchers in finding new candidates for superconductivity. The tool searches crystal databases and paper records for information regarding the properties of possible crystal configurations. It processes this information using statistical analysis to provide useful data at a glance.

Materials Search is useful for consolidating information in order to draw inferences on a particular material’s magnetic and electronic properties.
