Dr. Diwaker Jha

Hands-on coding and supervising the development of optical tools to measure asphere, free-forms, and elongated optics with nanometer accuracy. Delegating projects and coordinating with IT and manufacturing service providers.

Wavefront measurement and developing fast and automated fringe processing program in MATLAB, Python, & C

Developed: 1) Fourier based tool to deduce the effect of scale on physical parameters of porous media. 2) Method & tools to determine NMR relaxation in digitised complex 3D structures.

1) Nano scale 3D imaging by synchrotron based X-rays at : - Swiss Light Sources, Switzerland - European Synchrotron Radiation Facility, France - Neutron Scattering at SINQ, Switzerland) 2) Developed algorithms to process and mine several terabytes of data from Synchrotron based beam lines. - High level skills in Python (Parallel & GPU implementation), C++ & Matlab. - Wrote the entire application to do NMR simulation using billions of particles in Python, Cython, pyCUDA
