Physics and Astronomy Department Associate Professor Dr. Claudia Ojeda-Aristizabal and her student researchers study how electrons travel through materials with exotic properties in her lab, the Nanoelectronics Group.

Using techniques like low-temperature electronic transport and angle resolved photoemission spectroscopy (ARPES), ºÃÉ«ÏÈÉú students are unveiling new phenomena and using physics to describe them. Not only do research students work with a variety of in-house equipment, like a closed cycle cryostat and scanning electron microscopes, Dr. Ojeda-Aristizabal regularly brings students to UC Berkeley to work with their state-of-the-art synchrotron.

Understanding how electrons respond to different materials has the potential to make major impacts on current and future technology, such as quantum computing and low-energy-consumption microdevices. Students in Dr. Ojeda-Aristizabal's lab also travel the country, recently presenting at the University of Chicago and Cornell University, visiting labs at MIT and OSU and participating in trainings at UCLA.
