About Currently, I am a staff scientist in the Data Science at Scale Team at Los Alamos National Laboratory.
I graduated in mathematics and computer science and received my PhD in the Image and Signal Processing Group at Leipzig University.

Then, I worked as a postdoctoral researcher at IDAV at the University of California, Davis and
at the Computer Graphics and HCI Group at the Technical University Kaiserslautern.
My research interests include visualization, pattern recognition, vector fields
, moment invariants, Lagrangian flow representations, image processing, big data, and Clifford analysis.
