He is an Associate Professor, New Mexico State University, USA. His Areas of Expertise : Advanced research on innovative energy and novel materials for solar energy, fuel cells, hydrogen storage, sensors, electronic devices, and water cleaning. Dynamics and electronic and thermal transport in thin films, nanomaterials, materials, membranes, photocatalysts for manufacturing energy devices and environmental applications. Energy-water nexus by developing solar energy materials and processes to enhance surface-thermal-fluid interactions, and photons to electrons or heat conversion for solar driven water purification and desalination systems. Materials characterization using advanced analytical tools such as transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDS), atomic force microscopy (AFM), x-ray diffraction (XRD), x-ray photoelectron spectroscopy (XPS), and laser scanning confocal microscope (LSCM).
