🌌 Exploring the Universe through data, statistics and code...

I am an astrophysicist working at the intersection of cosmology, statistical inference and large astronomical surveys. My research focuses on extracting cosmological information from HII galaxies (like these NGC 604 / I Zw 18) using Bayesian frameworks and high-performance data pipelines.

Current status:

  • PhD student in Astrophysics (Universidad de Guanajuato)
  • ${H}_{0}$ measurement and Hubble tension through the $L-\sigma$ relation
  • Working on nested sampling and cosmological parameter estimation

Featured work methods:

  • Bayesian inference (nested sampling, likelihood modeling)
  • Spectral analysis and large-scale survey data (STARLIGHT, FADO, and CIGALE)
  • Statistical modeling and uncertainty quantification
  • Scientific Python ecosystem
  • HPC environments (SSH, SLURM, parallelization)

I build tools for:

💻 Technical Stack

snake animation

Scientific Python:

python anaconda Numpy Pandas Matplotlib Astropy Scipy Sympy ScikitLearn tensorflow bash bash bash

C/C++:

c++ ROOT

Bash & Linux:

bash Ubuntu

Git & version control:

git github

HPC workflows:

SSH Slurm

Additional tools:

julia JavaScript R LaTeX HTML5 CSS3 VScode Matlab SQLite MySQL Vim Wolfram

  I really like... well, the image above is pretty self-explanatory about what I enjoy in life 😛

I'm open to new projects / collaborations in academia or industry; places where I can gain experience through growth and innovation.

Research Interests:

Cosmology • Large-Scale Structure • Intergalactic Medium • Bayesian Statistics • Dark Matter Models • Survey Systematics • Dark Energy Models • Extragalactic Astrophysics • Extragalactic HII regions • Spectral synthesis

I’m interested in collaborations at the interface between:

Astrophysics • Data Science • Statistical Modeling • AI for Science • Metaheuristics & Machine Learning Optimization
