In my spare time, I love exploring the world and working on my home culinary abilities, including pasta making and home brewing.

By day, I am a Senior Application Engineer at the MathWorks with a background in power systems and controls engineering. I travel to work with our customers on modeling/simulation applications and predictive maintenance.

Professional Interests: Controls, estimation, machine learning, mobile robotics, energy storage technologies, batteries, power systems
