Picture of me

Hi, I am a doctoral researcher at the Technical University of Munich (TUM). My research is situated at the intersection of space-based networking and transport protocols, with a specific focus on LEO satellite networks and multipath transport.

At TUM, I am a member of the Chair of Connected Mobility (CM) led by Prof. Jörg Ott. I am also a member of the SPEAR Lab at TU Delft, led by Prof. Nitinder Mohan.

Please get in contact at hendrik.cech@tum.de. You can find my code on GitHub, my profile on Linkedin, and my CV.
