Current
Projects:
Presently, I am working in the field of Raman spectroscopy, laser induced breakdown spectroscopy and fluorescence spectroscopy. Under one of the research project jointly teamed with the UH medical school, I am developing micro-Raman techniques, which will be used for detection of various biological molecules and bio-agents. The project also aims to detect cancer in its early stage through spectroscopic techniques. Another project in the remote sensing area is mostly related to development of remote Raman techniques for geological and homeland security applications. The current research focuses on detection of minerals, organics, and explosive materials from a distance of 100 m in daytime or nighttime. Apart from Remote Raman system, I am also developing Remote Laser Induced Breakdown Spectroscopy (LIBS) and recently we were able to construct system, which is capable of performing both Raman and LIBS measurements simultaneously.
I have more than 17 years of research experience in the field of Condensed Matter Physics and Material Science. During my research, I discovered a new phenomenon in physics, which detects stress in materials with extreme sensitivity using electronic noise. Phenomenon has enormous applications in various fields and for making extremely sensitive stress, strain and chemical sensors. For geological application this new phenomenon may be able to produce next generation of earthquake sensor and other highly sensitive sensors based on stress fluctuation. My Ph.D. Dissertation is in the fields of 1/f electronic noise and High Tc Superconductivity, which are also my fields of specialization. I hope to come back to this field in the future if possible.
I also have expertise in the fields of thin film technology and hydrogen technology as well as in photo-electrochemical production of hydrogen using multi-junction solar cell, electrochemistry and electrochemical cell design, adsorption of hydrogen in zeolites and activated carbon at low temperatures, NMR study of solid and liquid hydrogen, and hydrogen embrittlement of solids. Other areas of experience include Single Crystal Growth, Thin film and Vacuum Technology, Low Temperature Physics, X-ray Diffraction, Electron Microscopy, Electronics, and Corrosion science.
