## Statistcal framework for Galaxy-Halo Connection on N-body Simulations
## Shear Inference with Hamiltonian Monte Carlo

- I developed [MultiCAM](https://github.com/ismael-mendoza/multicam), a multi-variable extension to conditional abundance matching (CAM) that can be used to connect properties
- We leverage JAX-GalSim to Michael Schneider's importance sampling [approach](https://arxiv.org/abs/1411.2608) to develop a new Bayesian pipeline for cosmic shear inference.

## Differentiable Forward Models of Galaxy Light Profiles

- We developed [JAX-GalSim](https://github.com/GalSim-developers/JAX-GalSim), a GPU-accelerated and differentiable version of [GalSim](https://github.com/GalSim-developers/GalSim), which is currently under active development.

## Statistical framework for Galaxy-Halo Connection on N-body Simulations

- We developed [MultiCAM](https://github.com/ismael-mendoza/multicam), a multi-variable extension to conditional abundance matching (CAM) that can be used to connect properties
of dark matter haloes with properties of galaxies.

*Above is a comparison of the correlation strength between predictions of MultiCAM and CAM, where MultiCAM can use the full mass accretion history (MAH) of a dark matter haloes as features for prediction.*

## Machine Learning models for mitigating the galaxy-galaxy blending problem in cosmology

## Framework for evaluating galaxy deblending algorithms

- I developed [BTK](https://github.com/LSSTDESC/BlendingToolKit) a software tool for simulating galaxy blends and consistent comparing galaxy deblenders based onv various metrics.
