Welcome on Florian Wiesner

I’ve joined Mistral AI as an Applied AI Scientist & Research Engineer.

Exploring formal methods in physics.

With this work, I wanted to explore whether the concept of foundation models (LLMs for language) can be applied to physics simulations.

This work demonstrates that geometry-optimized 3D-printed lattice electrodes achieve better electrochemical performance than conventional stochastic foams in alkaline water electrolysis, despite having lower surface area.

I gave a talk on physics foundation models for the StartUp First Principles, now available on YouTube.

I successfully defended my dissertation with highest honors, earning the title of “Dr.

I am starting to use AI agents to do the research for me, and here is my experience so far.

The main goal of this work was to tackle the reproducibility crisis in PEM electrolysis research.

I am revisiting my experience supervising more than 20 students in their research projects.

A new transformer-based model that learns multiple physical systems and generalizes to unseen scenarios.

This project serves as a boilerplate for training machine learning models.

Participated in the Merck Innovation Cup 2025, developing an innovative solution for multi-modal models in material discovery.

Excited to announce the start of my research stay working on Physics Foundation Models at the University of Virginia!

Accurate prediction of water content in fuel cells or electrolyzers is crucial for their performance.

We developed a novel experimental setup (microfluidic) to visualize and study the complex interactions between water and electrodes in CO₂ reduction reactors.

I am not only a software developer at work, but also enjoy working on personal projects.

Most winters, I try to get at least one week of snowboarding in.

If I find the time, I love to go hiking.

A simple N-body simulation implemented in C++.

A custom CUDA kernel for masked 3D convolution operations.

During this study, I had access to a metal 3D printer.

Became a member of the TriggerInk project focusing cartilage tissue engineering using 3D bioprinting.

Started my PhD journey in Chemical Engineering at RWTH Aachen University.

This was my Bachelor thesis.
