Mark Cappelli – Principal Investigator

Professor Cappelli received his B.Sc. degree in Physics (McGill, 1980), and M.A.Sc and Ph.D. degrees in Aerospace Sciences (Toronto, 1983, 1987). He joined Stanford University in 1987 and is currently a Professor in the Department of Mechanical Engineering and Co-Director of the Engineering Physics Program. He carries out research in applied plasma physics with applications to a broad range of fields, including space propulsion, aerodynamics, medicine, materials synthesis, and fusion.


Ben Wang – PhD Candidate

Benjamin Wang received his B.A. degree in Physics, and double majored in Economics at the University of North Carolina at Chapel Hill. He obtained a MS in Mechanical Engineering from Stanford. His current research is on developing plasma devices for applications in medicine and agriculture, as well as developing open source hardware for research labs.


Taemin Yong – PhD Candidate

Taemin Yong spent his undergraduate studies pursuing a degree in Mechanical Engineering at Seoul National University in South Korea and got his MS degree in Mechanical Engineering at Stanford University (2015). His research interests lie in generating plasmas in high pressure conditions and studying their kinetics. During his free time, he enjoys traveling and playing sports, especially table tennis.


William Riedel – PhD Candidate

Will completed a BS from Brown University and MS from Stanford in Electrical Engineering. After a few years as an optical engineer at Apple, he returned to Stanford to study plasma physics. He studies collisionality and kinetic behavior in high-energy, fully ionized plasmas relevant to inertial confinement fusion. His hobbies include basketball, snowboarding, backpacking, and the occasional rafting trip into McCovey Cove.


Andrea Marcovati – PhD Candidate

Andrea was born and raised in Milan, Italy. He received his BSc (2013) in Aerospace Engineering and MSc (2016) in Space Engineering from Politecnico di Milano. Andrea visited Stanford for the first time in 2015 to work on thrust and ion velocity measurements in Hall thrusters. After graduating he worked for the Italian company D-Orbit as a space system engineer. In 2017 Andrea decided to return to Stanford to pursue a PhD in Mechanical Engineering and work at SPPL. Andrea’s main research focus is the study of the formation of coherent structures in magnetized plasmas. Other than plasma physics, his interests include anything related to computer science and aerospace. In his spare time, he loves reading a good book and spending time with his beautiful wife Bea and daughter Laurel.


Jesse A. Rodríguez – PhD Candidate

Jesse completed his undergraduate studies at Oregon State University with HBS degrees in Physics, Mathematics, and Nuclear Engineering. He obtained a MS in Mechanical Engineering from Stanford. He is a devoted cinephile, avid golfer, rabid Laker fan, reluctant marathon runner, stoked snowboarder, broke watch collector, gym rat climber, and average landscape photographer. His research interests include studying plasma jets to gain insight into the fundamental physics of plasma turbulence and plasma photonic crystal devices for strange applications like cloaking and optical computing.


Adura A.T. Jibodu – PhD Candidate

Adura received his B.S. in Mechanical Engineering from the University of Southern California. After working as a consultant at Deloitte and a mechanical design engineer at Pratt and Whitney, he came to Stanford to study plasma physics. He is particularly interested in high energy plasmas and fusion applications, and is currently working on developing diagnostic systems to better understand kinetic behavior within such plasmas. Outside of academia, he is interested in cars, fitness, and movies.


Ryan C. Przybocki – PhD Student

Ryan received his undergraduate degree in Physics from MIT after growing up in Austin, Texas.  He is primarily interested in bridging fundamental plasma physics with engineering applications in research, particularly to advance the fields of fusion energy and propulsion.  He is currently working on measurement techniques for laboratory plasmas and seeks to engineer new devices to study plasma collisions.  Outside of research, Ryan enjoys powerlifting, playing guitar, watching The Big Lebowski, and searching for the best coffee in town.


Ahmed Abdalla – Undergraduate Student

Ahmed is a Sudanese American undergraduate researcher currently pursuing a double major in Physics and Math. His budding research interests lie at the intersection of machine learning and photonics. He hopes to continue his studies by pursuing a Ph.D in high-energy physics. When not studying physics, Ahmed divides his time between the Stanford Student Space Initiative, his euphonium, and watching cartoons with his little sister Asiel.
