I am a theoretical physicist whose research ranges from exploring the quantum world to studying emergent complexity in computational systems. I am dedicated to building a thriving, inclusive scientific community for students and faculty here at American University. As the Chair of the Department of Physics and Director of the Integrated Space Science and Technology Institute (ISSTI), my work spans from fundamental theory to the high-impact quantum and space science of tomorrow.

Current Research & Collaborations

My current projects include developing a new theory of long-range “2-2” quantum interactions between ultracold particles. I have also started a multidisciplinary research group of students and colleagues from Physics, Computer Science, and Mathematics to study self-emergent complexity; for example, we are exploring how behaviors in cellular automata can help us understand unexpected behavior in artificial intelligence.

Student Research

A central part of my mission—and a core philosophy of the AU Physics Department—is involving undergraduates in the discovery process. We work to ensure that every interested physics major has opportunities to engage in scientific research or engineering physics projects, from theoretical physics and computational science to experimental laboratory work. My colleagues and I are committed to making AU Physics a welcoming home for everyone, and we are known on campus for our close-knit community and events like our annual "Physics Phestivals," chili cookoffs, and "MentorShip" parties.

ISSTI and Space Science

In 2016, I helped found (and have directed since its inception) AU's Integrated Space Science and Technology Institute (ISSTI), which has supported research by 50 scientists funded by NASA, the NSF, and other partners. ISSTI researchers work on many of the most compelling challenges of the 21st century, including studying weather on Mars, developing innovative methods for studying exoplanets, studying the science and impacts of comets, designing advanced instruments for NASA missions, modelling the Sun’s dynamics and its effects on space weather, and utilizing observatories like the James Webb Space Telescope and the Hubble Space Telescope to explore the universe.

History

Before joining the AU faculty in 2006, I earned my PhD with the Gravitational Theory Group at the University of Maryland. As a postdoctoral fellow in the UMD Superconducting Quantum Computing group, I contributed to the theory for some of the first qubit and quantum gate prototypes. I later conducted research as an NRC postdoctoral fellow at the National Institute of Standards and Technology (NIST) on ultracold atomic physics and quantum information, specifically focusing on atoms levitated and controlled by lasers in optical lattices.

Professional Service

In addition to serving as Department Chair and Director of ISSTI, I have previously served as Associate Dean of Research for the College of Arts and Sciences. I occasionally advise the government as an expert on quantum science and technology, have served on the Council of Representatives of the American Physical Society, and served on the executive committee of the Topical Group on Few-Body Systems and Multiparticle Dynamics.
