Hi! I was born in Peru and immigrated to the U.S. on a full-tuition scholarship for my undergraduate studies, later earning a PhD in Mechanical Engineering from CU Boulder. I've called Boulder home for over a decade. I now work as a researcher at Lawrence Livermore National Laboratory, where I develop and code numerical methods to tackle complex multiphysics problems in flow dynamics and advanced manufacturing using high-performance computing. I like to describe my work as a mix of math, physics, and software – and I truly love it!

Outside the lab, I stay involved in civic life. I served on Boulder's Environmental Advisory Board, where I helped update energy codes and founded the Front Range Sustainability Council, connecting 13 regional boards. I also write opinion pieces on local issues as part of the Daily Camera's Community Editorial Board and currently serve on Boulder's Transportation Advisory Board.

My advice to students...

Based on my leadership experiences, my advice to students is to approach challenges with calm and curiosity. Leadership is not about having every answer; it is about creating clarity when things feel uncertain. When problems seem complex, break them into smaller, manageable pieces and focus on solving one at a time. This helps you keep momentum, learn along the way, and build confidence in your ability to tackle the next step. I have learned that staying composed and analytical, even under pressure, sets the tone for others and keeps a group moving forward. Progress often comes through steady problem-solving rather than dramatic breakthroughs. If you can stay calm, think clearly, and keep your team focused on the next achievable goal, you will not only reach solutions but also grow into a leader who inspires resilience and trust.
