Hi everyone. I am Sergio Contreras, from Colombia. I am Master in Engineering - Electrical Engineer of the Universidad Nacional de Colombia and now I am doing my PhD. in the planning of electric networks with renewable energies. Therefore, I am living in Bremen Germany and working as a researcher. I love outdoor activities since I like nature and sports. So I always try to practice sports such as trekking, hiking, climbing, mountaineering and mountain bike, as well as all the triathlon disciplines: running, swimming and cycling. I love landscape photography, therefore I like to go out with my camera to shoot sometimes. I also like salsa and bachata latino American social dancing styles. I consider myself open-minded, super relax, extrovertive and respectful.
