Research Interests

Research efforts are focused on experimental physics and material sicence, specially on nano-material fabrication and characterization, surface nonlinear optics and its applications. They include, quantum-dot and organic light emitting devices, second-harmonic-generation (SHG) probing of nano-interfaces, silicon nanocrystal patterning, novel quasi-phase-matched material and SHG microscopy.
