A focused team of researchers led by Prof. Barth F. Smets, pursuing Microbial Resource Management and Engineering activities. We work at the interface between environmental engineering and microbial ecology. The main topics we explore are: the engineered nitrogen cycle, water treatment biotechnology, gene flows in microbial communities. We work from the cell scale to the communities and system scales, using complementary approaches (bioreactors operation, microscopy, molecular community description, modelling, etc.)
Have you missed the last IWA Webinar on used water resource recovery technologies and how to model them? Dr. Borja Valverde-Pérez gave one of the presentations that you can check it
PhD candidate Antonio Delre, member of the LaGas project, will defend his PhD on Friday 23rd February, 2018, at 1 p.m. The title of the thesis is: "Greenhouse gas emissions from wastewater treatment plants: measurements and carbon footprint assessment". The defense will take place in DTU-Miljø, Building 113, room 011.
Ms. Yunjie Ma succesfully defended her PhD thesis on February 5th at DTU-Environment, entitled "Realizing autotrophic nitrogen removal in membrane-aerated biofilms". Congratulations to Dr. Marta Kinunen for the succesful PhD defence entitled "Invasion in microbial communities: Role of community composition and assembly processes".
Alex Palomo-Gonzalez and Carlos Domingo-Félez recently graduated and will remain as postdoctoral researchers in the group. Alex will continue to pursue comammox questions and Carlos on N2O dynamics and N-management. We welcome Elena Torresi (now formally) to our group. Elena has an 'industrial postdoc stipendium', supported by the Innovation Foundation Denmark and Krüger A/S. She will spend time at Krüger and DTU and collaborate with the research groups of Prof. Henrik Andersen and ours on the optimization of microbe-catalyzed trace pollutant removal during residual water treatment. We also welcome visiting PhD students Ms. Sike Wang, Mr. Junkang Wu and Dr. Hirotsugu Fujitani that will join the Metlab group during the next year.
