Education:

• Ph.D., Massachusetts Institute of Technology, 1983
• M.S., Electrical Engineering, MIT, 1981
• B.S., Electrical Engineering and Computer Science, MIT, 1979

Research Interests:

Shayegan’s group investigates electronic properties of GaAs/AlGaAs heterostructures, emphasizing quantum transport in ultra-clean systems. Key areas include fractional quantum Hall effect, composite fermions, Wigner crystals, and ballistic transport at low temperatures. His work combines molecular beam epitaxy fabrication with advanced measurement techniques to study correlated electron phenomena.

Notable Awards:

• Princeton University Graduate Mentoring Award (2002)
• Alexander von Humboldt Prize (2001)
• Fellow of the American Physical Society (1999)

His lab has pioneered studies of ultra-high-mobility 2D systems, revealing novel phases like valley superlattices and quantum Hall ferromagnetism. Collaborations with institutions like the University of Texas and ETH Zurich underscore his international impact. Current projects explore topological phase transitions and correlated defects in Wigner solids.

Affiliations:

Shayegan directs the Low-Dimensional Systems Lab at Princeton, advising graduate students (e.g., Adbhut Gupta, Chengyu Wang) and postdocs. His lab’s equipment includes advanced cryogenic setups for quantum transport measurements.
