About Me
At the age of 10 I was gifted my first PC which included a Basic compiler. I’ve been coding ever since.. Currently I am a PhD student at the University of Crete, expecting to graduate in summer 2021.

“Spice” is a state of the art spiking neural network simulator written in C++ and CUDA. It
- is up to 3x faster than the competition,
- allows you to specify your own models through a modern and intuitive API (you simply inherit from a model base class and override callbacks),
- builds out of the box without any 3rd-party dependencies (apart from CUDA), and
- does not involve any proprietary compilation steps or domain-specific languages.

We estimate human poses by treating them as missing/incomplete rows in a “pose database” matrix and calculating missing entries via matrix completion.

KinectFusion is a well-known 3D scanner powered by Microsoft’s Kinect camera. It has recently found its way into the official Kinect for Windows SDK. While KinectFusion produces very high-quality scans in real-time, it is limited to relatively small spaces.
In this paper we extend KinectFusion with a sparse data structure and streaming, allowing us to scan areas of virtually infinite size while maintaining the quality and performance of the original algorithm.

Unpublished BSc thesis
Voxels date back 20 years. They have many advantages over polygon meshes. However, they always suffered form the lack of a hardware-accelerated rendering pipeline and the infeasiblity of animating them. I tackled this age-old computer graphics problem in my BSc thesis. The (GPU-accelerated) animation technique I developed enables:
- Skeletal animation of voxels models
- Rendering of mixed polygon- and voxel-based content.

Experience
Bautembach Consulting
Founder
2014
Founded a startup with the goal to bring realtime 3D reconstruction to mobile phones, which ultimately failed. After bankrupting we open-sourced our protoype.
Consulted VRC on developing their 3D scanning booth “Shun’X”.
Research areas:
- Replacing polygon meshes with volumetric representations to unify the game content creation pipeline (combine modelling, texturing, animation into a single workflow).
- Non-rigid 3D reconstruction as an alternative to performance capture.
Developed cutscene animation tools for CINEBOX®, a film preproduction software based on the CRYENGINE.
Microsoft Research
Researcher
2012 - 2013
Scaled KinectFusion to scenes of arbitrary size.
Authored “FuSci”, a non-invasive foliage measurement software for the University of Cambridge’s biology department.
Designed a task planning software (“Maschinenbelegung”) for a local fulfillment service in Hamburg.
Created personal and commercial webistes.

Area of specialization: Spiking Neural Networks (simulation, multi-GPU parallelization, applications). See publications/projects for more. Expected to graduate in summer 2021.
University of Hamburg
BSc Computer Science
2007 - 2011
In my BSc thesis, tackled the decade-old problem in computer graphics of animating voxels.
Co-developed a realtime strategy game called Ink Wars.
