Mari-Karoliina Henriikka Winkler was born on July 9th 1980 in Hannover, Germany. Since her mother is from Finland she has a German-Finnish background. In 2001 she started to study Water Science at the University of Duisburg Essen, Germany. She did her bachelor thesis in the field of microbiology at the University of New South Wales in Sydney, Australia in 2004. Her Master thesis was supported with a scholarship (Ruhrverband), which she accomplished in the field of biotechnology at the University of British Columbia, in Vancouver Canada and received her Master degree in 2006. During her study time she worked in 3 different scientific institutions in the field of biochemistry and microbiology. After the university she worked for circa 2 years in the industry at Macherey-Nagel as Sales Manager for chemical equipment in Germany and Austria. In 2008 she joined the Environmental Biotechnology group of Mark van Loosdrecht at Delft University of Technology, The Netherlands to start her PhD. She accomplished part of her research at the Columbia University, in New York, USA, which was financially supported by the Columbia University. During her PhD she published several papers in international journals and presented her work on international conferences. With her research she won the Jaap van de Graaf prize from the engineering company WitteVeen+Bos for the best engineering paper in urban water related research in the Netherlands in 2012. She also won as the first woman, the Huber Technology prize, which is internationally awarded once every 2 years for the best invention in wastewater treatment, reflecting the quality of her work. She wrote two dissertations in two different fields (microbiology and process engineering) and received her PhD thesis in September 2012. She was awarded to be under the 4 best PhD students in 2011-2012 at the Technical University of Delft in water related research. The Association of Environmental Engineering and Science Professors committee and the company CH2M Hill (USA) awarded her thesis for the outstanding doctoral dissertation 2013*. This international prize is awarded once per year on the AEESP conference in the USA. After her PhD she worked as a technologist at GMB international, where she was designing wastewater treatments plants within Europe and published the research activities of the company in international journals and won for the bio-drying technology the B-IWA award for the best industrial invention in Belgium/The Netherlands. In 2013 she won Europe’s most prestigious Post-Doctoral scholarship (Marie Curie) to conduct research for 2 years in the field of mathematical modelling at the University of Ghent, Belgium. She is the newsletter editor of the specialized group for sludge management from the International Water Association. She was recently awarded the IWA/ISME bio-cluster award, which recognizes the importance of interdisciplinary research at the interface of microbial ecology and water/wastewater treatment. From 2015 onwards she will be appointed as assistant Professor in the civil and environmental engineering department at the University of Washington, Seattle (USA).
