Patricia Abellan received her Master of Science in Physics from Aalborg University (Denmark) and her Ph.D. in Materials Science from the Autonomous University of Barcelona (Spain). Her research focused on the study of defects at the atomic level, the interface structure between complex oxides and their relation to materials' properties. In 2011, she joined Prof. Nigel D. Browning's group at the University of California-Davis as a postdoctoral scholar. Her research focused on applying in situ methods to the investigation of materials at the nanoscale in relevant environments (fluid/gas).

Research Interests

  • In situ observations of materials at the nanoscale in relevant environments (fluid/gas).
  • Low dose imaging, atomic resolution imaging and spectroscopy in the TEM/STEM.
  • Development of the Dynamic TEM for microsecond in-situ observations at the nanoscale.
