Marc Strous is a professor and innovation fellow at the Department of Geoscience. Combining exciting science with real world applications, he strives to reduce greenhouse gas emissions associated with energy production. Scientifically, he has been successful with a blue ocean strategy, opening up entirely new fields of research multiple times. For example, he has discovered the bacteria responsible for anaerobic ammonium oxidation (anammox), unravelled the first anammox genome and metabolic pathway and translated the research into an actual application for wastewater treatment. The anammox process has been applied worldwide, at full scale, leading to the reduction of tons of CO2 emissions per day and generating significant revenue. He also pioneered the study of denitrifying methanotrophs, bacteria that convert nitric oxide into oxygen and made several key contributions to ecological interactions among bacteria, bacteria and protists and bacteria and plants. Currently, he is developing ecologically robust processes for conversion of atmospheric carbon dioxide to bioproducts and bioenergy with algae, and is exploring the impact of fugitive methane in the Alberta subsurface. Metagenomic and proteomic approaches feature prominently in the research and he has also made several contributions to bioinformatics. Marc Strous obtained his MSc (1995) and PhD (2000) at Delft University of Technology (The Netherlands). He worked as a Process Specialist at University of New South Wales (Sydney, Australia) and became a Professor of Microbiology at Radboud University Nijmegen (The Netherlands). From 2009-2013, he was a Max Planck Group Leader at the Max Planck Institute for Marine Microbiology (Germany). He started his current position as Campus Alberta Innovation Chair and Professor of Geoscience at the University of Calgary in 2013. Marc Strous is a specialty chief editor with Frontiers in Microbiology. Together with Angela Kouris, Agasteswar Vadlamani and Christine Sharp he founded Synergia Biotech Inc., a startup company that will produce natural products and renewable natural gas.
