Optimization with impact: my journey in public sector operations research.

Today, I gave a keynote talk at the Advances in Data Science & Operations Research Virtual Conference, presented by Universidad Galileo in collaboration with INFORMSttt. It’s the first INFORMS conference made for Latino America that brings together the scientific community from the areas of operations research, business intelligence, and data science. Dr. Jorge Samayoa, the General Chair, and Dr. José Ramírez, the Executive Chair, were wonderful hosts.

My keynote talk was entitled “Optimization with impact: my journey in public sector operations research.” My slides are below.

    I’m sorry I missed this. I would’ve love to see your keynote talk. I got my masters degree in operations research from Galileo University in Guatemala. Maybe next time.
