Hello! I'm Markus Toran, a security researcher and more.

In my free time, I enjoy hiking, board games, and experimenting with new programming languages. Feel free to connect with me!

Where I come from

I went to school in Karlsruhe, first to the Helmholtz-Gymnasium and later to the Carl-Engler-Schule, graduating there in 2018.

After school, I studied computer science at the KIT. I completed my bachelor degree in november 2021 with a thesis about verification of fairness properties for seat appointment methods. During my masters, I focused on IT Security. I wrote my master's thesis about IT Security and User Experience in the domain of Digital Identities.

After uni I worked as a security consultant at Secorvo Security Consulting GmbH in Karlsruhe. Currently, I am working as a researcher at Fraunhofer SIT in Darmstadt.

Where I'm going

I hope, my work will contribute to a more secure digital future.

Apps I Programmed

Android App development was a intermediate step for me into the world of programming. I have been developing Android apps since at least 2015. I initially got into programming as I wanted to create Minecraft mods, thus I learned Java. Latter, I transitioned to developing my own Games, first with Slick2D and then with LibGDX. LibGDX is cross-platform and allows for developing desktop and mobile games from a single codebase. I did not own an Android device when I started developing for it.

I bought a Pixel 9 Pro right after it was released. It now shows a vertical pink line on the display. A short rant.

Centrifugal Effects

Centrifugal effects describes when a subunit of an organization pulls away from the main organization. It's a concept I came across in the context of universities, but it can apply to any organization. I think it is a useful concept to understand and want to proliferate it.

I recently bought a lava lamp and I was inspired to create a website that showcases a colorful light. Check it out in decolight.toranm.me.

I noticed a recurring theme that I thought about: It's the concept of "highly refined things". A "thing" can be anything, I am mainly thinking about products, food items, software but also ideas. By "highly refined" I mean that the item was augmented upon from its basic form.

A fun and inspiring way to experience the web: browse the websites of architects, brick and mortar ones, not software.

I use Google Fit to track my health data extensively since the end of 2023. In the meantime, Google released Health Connect, which is a platform to store health data from different providers instead of them using the Google Fit API. In 2024, I got a new Phone (P9P), but my historical Google Fit data is not showing up on my new phone's Google Fit app. Now I found a workaround.
