Daniel Castro

Presenter: Daniel Castro


Daniel Castro is a patent attorney and entrepreneur. He has lived in Fresno since 2008, but grew up in East Los Angeles, where he graduated from Garfield High School. While in high school, Daniel was part of the Jaime Escalante Math & Science Program from which the movie "Stand and Deliver" is based. He received both a Bachelor's Degree and a Master's Degree from the Massachusetts Institute of Technology (MIT), where he majored in Electrical Engineering and Computer Science. While at MIT, Daniel had the privilege of taking a course with Dr. Amar Bose (audio pioneer and founder of the Bose Corporation) who mentored him and recommended that he merge his love for technology and writing by pursuing a career in patent law. Soon thereafter, Daniel attended and graduated from the University of California, Berkeley, where his studies focused on patent law and various other aspects of intellectual property.

Daniel has worked in the patent field for over 20 years and is currently a partner at the law firm of Loza & Loza. He has represented several Fortune 500 companies including Microsoft, AT&T, and Qualcomm. Daniel is also the CEO of OppJar, which is a Fintech startup he recently co-founded with classmates from MIT and UC Berkeley to address the country’s wealth gap problem in which an unacceptable number of kids enter adulthood with little or no savings.  


GM Panel Featuring Engineering Alumni


Jessica Gartrell - Design Release Engineer
Henry Rigdon - Exterior Validation Engineer
Diego Ruggiero - Software Integration Engineer
Kathryn Belmore - Propulsion System Calibration Engineer
Kody Martinez - Autonomous Infotainment Engineer

Jessica Gartrell grew up in the central valley (Madera, CA) and attended Fresno State as part of the Husband-Boeing Honors Program while pursuing a degree in Mechanical Engineering. While at Fresno State she was very involved in the Society of Women Engineers and Bulldog Racing as an officer for multiple years in both clubs. She also completed independent research with Dr. Law related to aerodynamics. With this leadership and academic experience, she had two summer internships before graduating. The first was with Northrop Grumman working as a mechanical test engineer on military communication satellites and the second with General Motors working in the full and reduced scale wind tunnels. Upon graduation in 2017, she moved out to Michigan to be part of the General Motors rotation program for new hires where she worked on full-size truck aerodynamics for the first year and crossover wind noise for the second year. She then moved on to work in design release responsible powertrain cooling components on Cadillac sedans and is currently a Design Release Engineer for the GM Defense Infantry Squad Vehicle. In the meantime, she is also pursuing a Master's Degree in automotive and manufacturing engineering from the University of Michigan.

Kathryn Belmore is a Propulsion System Calibration Engineer working on electrified vehicles at General Motors. She began working in automotive 3 years ago as a Rotational Engineer working in roles across General Motors involving CAD, dyno development, virtual vehicle simulation, and systems engineering. Kathryn graduated from Fresno State in 2017 with a bachelor’s degree in Mechanical Engineering and was a part of the VIP program working at Gusmer Enterprises, Inc and International Paper.  

Kody Martinez is a curious engineer with a mixed automotive background. Currently working on GM's autonomous vehicle supporting the infotainment system. Open to change and looking for opportunity Kody has moved fluidly through GM holding a variety of positions including Performance Engineer N&V, Electrical Quality Engineer, Driveline Design, & Driveline Development. After graduating from California State University Fresno with a degree in Mechanical Engineering he moved to Michigan to pursue a job where he could have fun working on hard problems that enable others to be mobile in the city or off-roading in the wilderness!  

Diego Ruggiero graduated from Fresno State in 2018 with a bachelor’s degree and again in 2020 with a master’s degree, both in mechanical engineering. In the past he has interned for Tesla as a mechanical design engineer for the equipment engineering team and now he currently works as a software integration engineer at General Motors (GM). Diego’s current projects revolve around GM’s new electrical architecture that will go on many upcoming vehicles such as the Hummer EV and Cadillac Lyriq, as well as their autonomous fleet. 

Henry Rigdon graduated with a Bachelor of Science in Mechanical Engineering in May of 2017. While studying at Fresno State, Henry interned at Hilmar Cheese Company and PepsiCo. Since graduating, he has worked in the automotive industry at General Motors. He has experience in vehicle dynamics & load prediction CAE as well as road load data acquisition. He is currently working as an exterior validation engineer.

Cybersecurity in the Age of Autonomous and Connected Vehicles

The Internet of Vehicles (IoV) is an inter-network of autonomous and connected vehicles that interact with one another using an ensemble of wireless protocols, creating an ecosystem of intra-vehicle, inter-vehicular, and road-side communications. Such an ecosystem alleviates traffic congestion, increases driver safety, improves user convenience, while introducing a myriad of cybersecurity challenges. Dr. Tayeb will review IoV cybersecurity requirements, showcasing some of the recent attacks against this ecosystem, the emerging standards and legislation in this domain, as well as opportunities and future directions.

Presenter: Dr. Shahab Tayeb
