Tim Scheller

I am a researcher at LIX Ecole Polytechnique, working on creative AI in computer vision and graphics, supervised by Maks Ovsjanikov and Marie-Paule Cani.

Previously, I received my Masters in Computer Science from TH Cologne during an exchange at LIX in 2023, developing generative AI models for 3D scans. In winter 2020, I co-founded PhoGrow to provide digital twins of plant growth, using neural surface reconstructions. From autumn 2018 to summer 2022, I worked at Charamel, to synthesise photorealistic humans for 3D real-time applications, starting as a full-time intern and continuing part-time during my studies.

My passion is to push the boundaries of current technologies, and prototyping solutions for tomorrow's challenges, such as the sustainable computer science Hackathons I organise in my free time.

Since 2023, I have been working full-time on creative AI at the Computer Science Laboratory of the Ecole Polytechnique in Paris (LIX). I started as a research engineer in the Vista research group working on deep sketch-based modelling under the supervision of Marie-Paule Cani, and transitioned to the Geometry Deep Learning research group led by Maks Ovsjanikov.

From 2019 until 2022, my responsibility at Charamel was to develop a pipeline for synthesising photorealistic humans, which involves capturing, rendering and animating them in 3D. In addition, my role was to improve the company's web-based real-time graphics engine and authoring system, as well as to develop tools for animating and exporting content.

In 2018 I wrote my Bachelor Thesis during an internship at Charamel, where I implemented a WebGL application to render and animate digital humans in real-time. The former involved modelling subsurface scattering of skin, whereas the latter was based on performance capture, to model facial expressions and wrinkles.

In 2017, we developed a paragliding simulator in VR, where participants sat in a real harness to fly through a virtual environment. My role was to implement an inverse kinematic system for accurate and immersive body interactions, based on the user's movements.

In March 2023, we organised a 2-day hackathon to develop sustainable solutions to tackle the problems caused by 'Fast Fashion'.

In October 2018, we hosted and organised a 2-day game jam to raise awareness about the environmental issues caused by coal mining. About 20 people participated and created 4 different games.
