John Vassberg
Dr. John Vassberg was Chief Aerodynamicist of Boeing’s Phantom Works. He innovated efficiency improvements on more than 20 Boeing aircraft, most notably the introduction of winglets. He’s been awarded some of the highest honors in aerospace engineering, including the AIAA Aerodynamics Award, and was elected to the National Academy of Engineers, Class of 2025.
David Sandhu
David Sandhu formerly worked for SpaceX, Raytheon, and Lockheed Martin as an engineer before he transitioned to the financial services industry. After his father passed away, Sandhu helped his mom through some tough financial questions, and that gave him the spark to pursue a career in financial planning.
Sandhu is passionate about serving others and lives by Zig Ziglar’s famous saying, “You can have everything in life you want, if you will just help enough other people get what they want.” He knows first-hand that true happiness is experienced when helping others. Sandhu is an investment advisor representative with EverSource Wealth Advisors, a registered investment advisor.
John Bennewitz
Dr. John Bennewitz is an assistant professor in the Mechanical & Aerospace Engineering Department at the University of Alabama in Huntsville. He is the principal investigator of the Advanced Propulsion, Energy and Combustion Science Laboratory (APECSLab), managing a group of students to pursue research into advanced propulsion systems for liquid and solid propellants and power generation. Prior to joining UAH, he was the principal investigator for the rotating detonation rocket engine (RDRE) program at the Air Force Research Laboratory (AFRL). During his five years at AFRL, he performed over 2000 successful hot-fire tests of developmental RDRE hardware that demonstrated robust detonation and operability for a wide range of injection designs. He received his B.S. in Mechanical Engineering from the University of Pittsburgh in 2008, before completing his M.S. in Aerospace Engineering from Georgia Institute of Technology in 2010 and his Ph.D. in Mechanical Engineering from the University of Alabama in Huntsville in 2015. Upon graduation, he worked as a postdoctoral research scholar at UCLA’s Energy and Propulsion Research Laboratory studying acoustically-coupled fuel droplet combustion. His present research focuses on investigating fundamental detonation physics and engine scaling mythologies of small-scale detonation-based engines for in-space applications.
James "Jim"’ Heidmann
Dr. James (Jim) Heidmann currently serves as Manager of NASA’s Advanced Air Transport Technology Project. In this capacity, he leads NASA’s technology development for subsonic transport aircraft. Prior to this role, he served as Acting Deputy Director of NASA’s Advanced Air Vehicles Program, managed NASA’s Advanced Air Transport Technology and Transformational Tools & Technologies Projects, and also served as Chief of the Turbomachinery and Heat Transfer Branch. In addition to these management roles, Dr. Heidmann spent 20 years as an Aerospace Research Engineer, publishing over 20 papers and journal articles in the area of turbomachinery aerodynamics and heat transfer. He was elected Fellow of the American Society of Mechanical Engineers (ASME) in 2007, Associate Fellow of the American Institute of Aeronautics and Astronautics (AIAA) in 2015, and received the Outstanding Mechanical Engineer (OME) Award from Purdue University School of Mechanical Engineering in 2017. Dr. Heidmann received a Bachelor of Science in Mechanical Engineering from the University of Toledo in 1986, Master of Science in Mechanical Engineering from Purdue University in 1988, and Doctorate in Mechanical and Aerospace Engineering from Case Western Reserve University in 1997.
