Driving Innovation and Excellence Together
Fueled by volunteers, the organization has dozens of continental committees and over a hundred local chapters facilitated by a Board of Directors affectionately known as The Core.
Each position is a two-year volunteer position and elected by the NAYGN membership except for the presidential positions. A Board Director is elected to the Vice-President position and then serves a three-year term going from Vice-President, President, and then Past-President each year.

Megan Lubbers
PUBLIC INFORMATION OFFICER
Instrument and Controls Engineer in Long Term Plant Reliability group at Palo Verde Generating Station. I have been working at Palo Verde since I graduated college in 2018 from the University of Arizona with a degree in Electrical and Computer Engineering.
I have been an officer of Palo Verde’s Young Generation in Nuclear chapter for 2 years. First as safety officer, and then as President. I have also supported the NAYGN Delivery Team for the Global Clean Energy Action Forum, RE+2023, and COP28. My passion for student outreach and STEM advocacy was ignited during my college years when I served as an intern for the Women in Science and Engineering Program. This experience cultivated my dedication to fostering inclusivity and promoting the significance of STEM fields, values that I have carried with me as I became a nuclear advocate though PVYGN.
As Public Information Officer I aspire to create an inclusive space wherein the younger generation is not only well-informed about nuclear science and technology but is also inspired to contribute to its evolution. I want to recreate any lost community connections that might have occurred since covid, and solidify nuclears presence within our communities and schooles. Together, we can use our passion for nuclear advocacy to demonstrate how nuclear innovation can play a pivotal role in shaping a sustainable and clean future for all.
