My Research Interests: 

• Topological phase transitions in ferroic materials including topological defects, domain walls and Skyrmion structures.
• Development of new synthesis techniques for novel ferroelectric oxides with topological properties
• New nanolithography techniques to fabricate ferroelectric domain wall memory devices
• Investigation of nanoscale domains and topological transitions in ultrathin ferroelectric films
• Characterization using scanning probe microscopy (including piezoresponse force microscopy, conductive atomic force microscopy, Kelvin probe force microscopy, electrostatic force microscopy, etc.).
