About

As a PhD candidate at Stanford University, I work with Professor Stephen Boyd on algorithms and software for modeling and solving convex optimization problems.

Before attending Stanford, I was a consultant and data scientist at McKinsey, where I worked on quantitative projects in the automotive and energy sectors. I received my MSc in Robotics, Systems and Control from ETH Zurich, where I was awarded the Willi Studer Prize for the best degree and the ETH Medal for my Master's thesis. I received my BSc in Mechanical and Process Engineering from TU Darmstadt, with the VDI Prize for the best degree.

Software

CVXPYgen is a tool that generates custom solver implementations in C for convex optimization problem families modeled with CVXPY. It is suitable for embedded systems and also provides a Python wrapper for desktop applications.

LPCF is a framework for fitting a parametrized convex function to some given data, compatible with disciplined convex programming. This allows to fit a function that can be used in a convex optimization formulation, directly to observed or simulated data.
