Alex Cronin

Professor of Physics

Professor in the College of Optical Sciences

Classification: Primary Faculty

Education: Ph.D., 1999, University of Washington

Fields of Study: Atomic, Molecular, and Optical Physics

Research Interests: 

In my atomic physics laboratory we study atom optics, atom interferometry, precision measurements, van der Waals forces, atom-surface interactions, atomic polarizabilities, atom-field interactions, laser spectroscopy, quantum (de)coherence, and atomic and molecular beam sources and detectors. My renewable energy research team collaborates with Tucson Electric Power to study the performance of grid-connected PV power plants. We measure PV system efficiencies, degradation rates, and energy yields. We also study the variability of solar power and collaborate with the UA Renewable Energy Network on forecasting the output of solar power plants.

Honors and Awards:

2009 Honors College Outstanding Professor Award, UA Honors College.

2008 Early Career Distinguished Teaching Award, UA College of Science.

2005 Outstanding Undergraduate Teaching Award, UA Dept. of Physics.
