About Me

Currently a Postdoctoral researcher focused on simulations of metal and alloy surfaces under high electric fields using density functional theory. With extensive background in experimental research using various characterization methods and a keen interest in the development of simulation and analysis methods for atom probe tomography and field ion microscopy. My research also encompasses the application of machine learning and data mining techniques in material science.
