About Me
Greetings, fellow denizen of the interwebs! My name is Antonio (I usually go by Tony).
I am working on building reliable and useful LLM agents at Dialect AI. We were in YCombinator's S22 batch.
In the summer of 2022, I finished my PhD at Stanford University. I was fortunate to be advised by Prof. James Zou in the Stanford Laboratory for Machine Learning, Genomics, and Health. I was gratefully supported by a Stanford Bio-X Graduate Fellowship. Get in touch at tginart at stanford dot edu.
When I'm not writing code, cleaning datasets, or (failing at) proving theorems, you can probably find me tumbling down shredding the ski slopes or hero calling at the poker table.
I am a full-stack ML researcher who is passionate about building the next generation of machine intelligence. I've led a variety of state-of-the-art projects in machine learning, data science, and data processing while blending theoretical, algorithmic, and systems work. Many of these have resulted in papers published in top AI venues (for example, NeurIPS), contributions to open-source projects with thousands of users, and contributions to production systems serving billions.
Research Interests
I am broadly interested in artificial intelligence, cybernetics, and information science & engineering. My doctoral research is on theory and algorithms for large-scale machine learning. I work on making ML systems more efficient, scalable, secure and easier to deploy.
