My research sits at the intersection of causal inference, machine learning, and foundation models — translating theoretical advances into real-world applications across biopharma, agriculture, finance, and systems engineering.

I majored in Mathematics at the University of Guanajuato and CIMAT. I’m thankful for the formative path I’ve gain over these years, the guidance of professors at UW-Madison and CIMAT have shaped who I am, and every milestone I reach carries a positive influence of my mentors.

How I work

I want my work to be useful for the social good — to advance research and to impact the quality of life of many. I believe the way to achieve great things is through collaboration, rapid iteration, and hard work. In my collaborations, I try to make people feel supported and valued, so we can both do our best in our contributions.

A tangible reflection of this: I’m currently the #4 contributor on the UW–Madison DSI open-source leaderboard.

A summary of my ongoing work lives in the DSI research portfolio. The best way to reach me is by email.

Far better an approximate answer to the right question, which is often vague, than an exact answer to the wrong question, which can always be made precise.
