Top 3: Learnings on research and science

Scientists are story tellers. For a long time, I thought scienstists say what is (re-contextualizing Augstein) and the scientific method produces the output logically determined like a mechanical system. However, turns out the scientific method is a only tool to figure out a story as it unfolds. Still, the scientist needs to tell it. At least, the impactful scientist.

In fact, I think every impactful individual is a story teller. Only by telling a story do you convince reviewers, students, supervisors, and job candidates. And, most importantly, convince yourself.

Of course, there are differences between scientific stories and other stories. Why do you tell a story? How do you tell a story? To whom do you tell a story? How convincing is your story? How much does your story correspond with reality, how plausible is it, and how well is it grounded in scientifically tenable statements? I'd say, scientists are some of the best story tellers in the world as they tell a previously untold story. An optimistic story. As stringent as it gets. An easy-to-follow story for an often highly complex, non-fictional plot.

Thoughts inspired from discussions with Reinhard Schütte, Tobias Grosse-Puppendahl, and Bettina Luescher.

Science is the endeavour of solving difficult problems under uncertainty. These difficult problems are generally rooted in the lack of non-trivial knowledge.

That's why great science is closely related to great enterpreneurship. Both activities share that they are predominantly characterized by uncertainty. Sometimes, the whole problem and its boundaries are uncertain. Sometimes, the problem determinants are uncertain. And sometimes, "only" the solution to an already well-structured problem is uncertain.

Therefore, conducting research is mostly the process of eliminating uncertainties, e.g., through implementation, observation, or reasoning.

Thoughts inspired from discussions with Reinhard Schütte and Andreas Fender.

Individuals make the difference. Institutions have no talent, knowledge, skill, experience, or expertise. Individuals do.

Of course, institutions are better or worse in their tendency of attracting individuals with talent, etc. But talented people can be where you don't expect them and vice versa. Therefore, you need to be on the constant lookout for talent.

In science-and any creative role really, this specifically means if there is a great outcome, it is not due to the institution. It is because of one good individual. And, maybe they were renting out DVDs in the video rental store, only to write and direct Pulp Fiction a few years later.

Sometimes, one might think there are whole teams or departments that created something. But there is no next-level support when you are already at the edge. Nope, in fact, the better the outcome, the lower the number of people that are behind it. Either you solve whatever problem, or it remains a problem. Either you are the expert, or no one is. Either you develop the skill, or no one has it. Either you do it, or no one does.

PS: Especially in larger organizations, there is the tendency to develop the believe that good processes can replace good individuals. That's a fallacy. (I've never heard anyone talk of Agile Development in any good software company. Just get your code into CI.)

Thoughts inspired from discussions with Reinhard Schütte, Christian Holz, and Daniel Cremers.

Industry Experience

Apple
Hardware Tech | Sensor Software & Prototyping
Advised by Dr. Tom Runia and Dr. Vittorio Megaro in Dr. Brian Amberg's Zurich Vision Lab, I've worked on AI-based 3D computer vision for the future of FaceTime Personas on Apple Vision Pro.
Meta
Reality Labs | Research
Advised by Dr. Raj Sodhi in Dr. Hrvoje Benko's interaction research team, I worked on Mixed Reality experiences with semantic scene awareness.
Porsche
Finance & Technology

Advised by Dr. Tobias Grosse-Puppendahl and Jochen Gross, I co-founded Porsche Emerging Tech Research and made it successful within 18 months (incl. 2 first-author papers and > 15 patent filings). My work focused on context-aware in-car and around-car mixed reality systems. I hired and guided people, built the ML stack, and pushed organizational boundaries on the way.

Before my PhD, I was advised by Dr. Andrada Junge and Martin Mayer as a data science intern on vehicle quality analyics, authored my master's thesis on estimating remaining EV battery life from past usage in a fleet-learning approach, and joined as a freelance data engineer to build a parallelized terabyte-scale vehicle data processing pipeline.

Accenture
Strategy
I interned on a strategic post-merger integration initiative for an automotive client to develop a migration and integration plan towards a cloud-native microservice architecture, following the acquisition of multiple mobility startups.
Cinuru
I interned as a software engineer at Cinuru - a MediaTech startup from the ecosystem of the Hasso Plattner Institute and the Film University Babelsberg in Potsdam, working on FFT-based movie trailer recognizition on off-grid mobile phones.

Academic Experience

ETH Zurich
Department of Computer Science | Institute for Intelligent Interactive Systems
I was a visiting PhD student to Prof. Dr. Christian Holz's Sensing, Interaction & Perception Lab to work on space-constrained input in mobile VR.
California State University, Los Angeles
During my Master's degree, I was awarded a Fulbright full grant for studying a term in the United States.
University of Duisburg-Essen
Faculty of Business Administration | Institute for Computer Science and Business Information Systems
Before joining Prof. Dr. Reinhard Schütte's Integrated Information Systems research group as a PhD student in Computer Science, I obtained a bachelor's and a master's degree in Information Systems, and had worked as a student assistant in Prof. Schütte's group and Prof. Dr. Stefan Eicker's Software Engineering research group.
