Dr. Alan Farhan
Assistant Professor of Physics
Education
- Ph.D. - Physics, University of Basel, Switzerland – 2014
- M.Sc. - Physics, Vienna University of Technology – 2009
Biography
Following a PhD project at Paul Scherrer Institute, Switzerland, Dr. Farhan was awarded a so-called mobility fellowship from the Swiss National Science Foundation (SNSF) in 2015, which allowed him to join Dr. Andreas Scholl at the PEEM3 endstation of the Advanced Light Source, to perform independent research activities on artificial frustrated spin systems and oxide thin films. He was then awarded a Return Fellowship from the SNSF to continue his independent research activities at the Swiss Light Source. This was followed by a postdoctoral stint at Aalto University, Finland, between 2019 and 2022, after which he joined Baylor University as an Assistant Professor in 2023.
Research Interests
Magnetic nanostructures, oxide thin films, frustrated systems, emergent phenomena and synchrotron-based spectromicroscopy
