Museum staff are passionate about STEM and about helping our community discover their world. Some staff have taken that passion to another level to become subject matter experts in specific areas. Like crush-it-on-Jeopardy-level knowledge.

If you're looking for someone to talk about just about any area of science, technology, engineering and math, contact us and we'll see which of our experts might fit the bill.

Matt Baker

A long-time member of the education team, Matt is the Museum’s resident HOMAGO expert – hanging out, messing around, geeking out. That may seem antithetical to getting work done, but that philosophy guides Matt’s team of educators in both The MiX and The Forge, the Museum’s makerspaces. Pedagogical methods, such as constructivism, constructionism, project- and problem-based learning, and hands-on STEM lessons, plus cross-generational and teen-focused instructional design and facilitation, are Matt’s specialty. He has dual undergraduate degrees in history and education studies from Guilford College, and his masters in curriculum and instruction from Virginia Commonwealth University.

Justin Bartel

Justin turned a lifelong interest in space into a professional immersion. After earning an astronomy degree from the University of Arizona, he worked at museums in Kansas and Florida before coming to the Science Museum of Virginia. Justin manages the Museum’s Dome, utilizing the Digistar system to create unique astronomical visualizations for in-person and online audiences. Museum-produced planetarium content has been shared with colleagues around the world and recognized with multiple awards. Justin has served as president of the Digistar Users Group, and is a member of multiple planetarium associations and the American Astronomical Society. Whether it’s astronomy, planetary science, space exploration or planetariums, Justin’s expertise is out of this world.

Richard Conti

Appointed director of the Science Museum of Virginia in January 2008, Rich is only the third person to serve in that role since the Museum opened in January 1977. As Chief Wonder Officer, he oversees a 223,000-square-foot building that houses four floors of interactive experiences, a 33-acre campus, and two satellite locations. In addition to facilitating new exhibits and major infrastructure upgrades to enhance the guest experience, Rich orchestrated a master planning and fundraising effort, which generated more than $50 million in capital investment and led to the building of a new multipurpose space. Before coming to Richmond, Rich was the Executive Director of Nauticus and an Assistant to the City Manager in the City of Norfolk. Rich has degrees in business management from Tulane University and public administration from the University of Southern California, and is a graduate of the Navy Fighter Weapons School (TopGun). As a U.S. Naval Aviator, he amassed 1,000 flight hours and 250 carrier-arrested landings as a backseater (RIO) in the F-14 Tomcat. If it’s aviation technology, museum management, strategic planning, the importance of STEM in everyone’s life or pop culture puns you want to discuss, Rich is your guy.
