Current Open Positions

1. Data analytics for image processing

Required skills: Python, Statistics, Image processing

A single experiment run yields thousands of X-ray scattering images, and our objective is to employ Python for processing these images. We will utilize the correlation function to mathematically articulate the relationships between these images. Employing Python for statistical analysis will help unveil the distribution characteristics of the correlation function, providing insights into the atomic-scale dynamics of the material being studied.

2. Multiphysics simulation for electronics packaging analysis

Required skills: LT-SPICE, Cadence, COMSOL, ANSYS

3. 3D printing with ISRU Lunar simulant

Required skills: Solidworks, Mechanical testing, 3D printing

4. Functional nanocomposite film with microtopography

Required skills: Nanocomposite fabrication, CFD (OpenFOAM)
