 Hi, my name is Marcelo van der Waals and I'm in my fourth year of the PSD at the laboratory of microbiology at Wageningen University and Deltares, a water-related institute in the Netherlands. I'm 27 years old, living in Utrecht together with my boyfriend, and love to go outside for hiking, cycling and playing field hockey. I studied earth sciences and specialized in environmental hydrogeology during my master's at the Utrecht University. But I shifted more towards the microbes and microbiology during my PSD. In this lab, I'm doing most of my experiments, so here you can see all our continuous cultures degrading many different compounds. Once every two weeks, I'm working at Wageningen University to perform part of my experiments and to stay in touch with many other students, PSDs, postdocs and professors. Thank you for watching.
