My research interests span computer networking mainly with a focus on the upper layers. I am currently involved in projects examing low latency communication, in particular in relation to multi-path systems with applications to practical settings such as providing Internet access to passengers onboard trains. I also have a general interest in internet access performance of Starlink and on mobile platforms such as train-mounted cellular aggregation routers, as well as using deterministic network emulation to evaluate internet-based applications and protocols is also a topic of interest.

• Systems Modeling and Simulation
• Thesis advisor for Masters’s Project 
• Thesis advisor for Bachelor’s Project 

I have been project manager or subprojet manager for several projects, in most cases also involving industry partners such as Icomera. 

I am currently sub-project manager within the 8-year DRIVE project working on measurements and evaluations of techniques to provide low-latency communication.

Prior to this I was sub-project manager within the 6-year HITS project investigating novel communications solutions, and another recent project was TRUEdig where the main focus was on exaplainabilty of ML and related techniques. 

Further back I was initiator and project manager for the KauNet project funded by the Swedish foundation for Internet Infrastructure  to enhance the KauNet emulator codebase and documentation.

I had a five month research visit at Ecole Nationale Supérieure d’Ingénieurs de Constructions Aéronautiques (ENSICA), Toulouse, France to do research and deveolpment of programmable emulation with applications to satellite  communications. 

Investigator in “Reliable and Secure Communication in SCTP”, funded by the Knowledge Foundation of Sweden. In collaboration with Tieto Enator AB and Ericsson AB.

Co-work package leader for work package 6 on “Protocols and Architectures, and Traffic Modeling for Wireless Networks” of the EU FP6 Network of Excellence Newcom with more than 60 academic and industrial partners. 

Johan Garcia is an Associate Professor of Computer Science at ������ý in Sweden, where he received his Ph.D degree in 2005.
