Title slide: Interpreting Cosmological Information from Neural Networks in the Hydrodynamic Universe
May 2026

Journal Club presentation on "Interpreting Cosmological Information from Neural Networks in the Hydrodynamic Universe". This talk details how neural networks extract cosmological information from hydrodynamic density fields, exploring how CNNs marginalize over complex baryonic effects to constrain cosmological parameters.

Title slide: Deep Learning the SFR with Spectral Kinematics of High-z Galaxies?
April 2026

Contributed talk at the DAOISM workshop on ISM studies with data science and PPV spectral cubes, held at the Institut d'Astrophysique de Paris (IAP), France. Presenting high-z interferometric denoising benchmarks and physical property inference using deep learning and sparsity.

Diagram tracing which neurons drive a galaxy-morphology classifier's prediction, layer by layer
Teaching notebook

A hands-on walkthrough of neural network explainability — saliency maps, integrated gradients, and mechanistic circuit-tracing — built up from a toy classifier to MNIST, ImageNet, and a galaxy morphology model.
