Writing and Research
Selected work
- Growth Signals — CTO and Cofounder. I lead all software engineering, data science, and AI research for a GenAI platform purpose-built for R&D and Innovation teams.
- Moderna Therapeutics — I was the first Data Scientist at Moderna and grew the Data Science and AI team from the ground up. My work focused on applying machine learning and statistical techniques to improve mRNA medicines, and on software engineering for ML and generative AI platforms.
- Harvard Medical School — Ph.D. with Bernardo Sabatini (synaptic signaling in hippocampal neurons); postdoc in Sandeep Datta’s lab (olfactory system).
