  Ph.D. -- Physics, Pennsylvania State University (2001)
Ph.D. minor -- High Performance Computing, Pennsylvania State University (2001)

Research Interests

  • Ab initio calculations of electronic, structural, and magnetic properties of materials
  • Nanostructured materials and their applications
  • Electron-phonon coupling and phonon renormalization in metals
  • Quasi-particle properties in strongly correlated systems
  • High performance computing

  My long-term research objectives are unified around the theme of understanding and predicting materials properties from first principles, with emphases on nanostructured and other novel materials, computational materials design, and development of new theoretical and computational techniques.
