I am a Schmidt Science Fellow and a President's Postdoctoral Fellow with the H. Milton Stewart School of Industrial and Systems Engineering at the Georgia Institute of Technology. My postdoctoral mentor is Alejandro Toriello.

This Fall, I will join the Department of Mathematical and Statistical Sciences at the University of Colorado Denver as an Assitant Professor.

I am interested in discrete optimization, game theory, enumerative and algebraic combinatorics, and real-world applications in transportation and public decision-making.

I earned my PhD in Applied Mathematics from the Center for Applied Mathematics at Cornell University (2023). My PhD advisor was Samitha Samaranayake. My other committee members were Pamela E. Harris, David Shmoys, and Bobby Kleinberg. Prior to that, I earned my BSc in Civil Engineering and minor in Computer Science from the University of Illinois at Urbana-Champaign (2017). My undergraduate research advisor was Daniel B. Work.

Prior to joining Georgia Tech, I was a Postdoctoral Fellow at SLMath (formerly MSRI). I have also participated in semester-long research visits at ICERM and IPAM, research internships at Amazon.com and Bosch North America, and REU mentoring at MSRI and ICERM.

Outside of work, I am a coffee enthusiast and I practice taekwondo.

I was born and raised in Guayaquil, Ecuador.

Are you wondering what's a parking function?

Are you wondering who's the GOAT?

Are you wondering what's combinatorics?

axioms

I subscribe to Federico Ardila's axioms:

Axiom 1. Mathematical talent is distributed equally among different groups, irrespective of geographic, demographic, and economic boundaries.
Axiom 2. Everyone can have joyful, meaningful, and empowering mathematical experiences.
Axiom 3. Mathematics is a powerful, malleable tool that can be shaped and used differently by various communities to serve their needs.
Axiom 4. Every student deserves to be treated with dignity and respect.

about my last name

In formal settings (e.g., legal documents, publications), it is Martínez Mori; two words separated by a space, not a hyphen. In informal settings, it is just Martínez. Note this Wikipedia article on naming customs of Hispanic America.
