Diwaker Jha

Research Interests:

I am interested in developing new methods for high resolution imaging, investigation of porous materials by means of X-ray scattering techniques, small angle scattering, X-ray reflectivity, micro and nano tomography using synchrotron radiation sources, study of flow properties, pore throat distribution and their time dependent evolution supplemented by in-situ measurements.

With my previous experience in working with several different institutions, I have gained experience in high resolution optical microscopy (Near field optical microscopy, Confocal laser scanning microscope, Phase contrast acoustic microscopy), Advanced signal and data processing, RF signal generation and detection. High speed electronics, Ultrasound tomography, holographic image reconstruction and phase contrast imaging, Structural health assessment (EU FP7, AISHA II), NMR systems and Neurophysical data analysis (4D fMRI data, EEG) and instrument modifications, Plasma physics, Electron microscopy and analysis, Semiconductor thin films, Ultra high vacuum reactors and thin film deposition, FPGA programming and implementation, and Robotic systems.
