Masters thesis in Soil Chemistry August. 1992 Ph.D. - Agronomy – Environmental agro-technology (Royal Vet. & Agricultural Univ., DK).   APPOINTMENTS August 2018- Professor at Aarhus University, Department of Engieering May 2007 –July 2018: Professor at University of Southern Denmark in Environmental Technology August 1988 – July 2007 Seniorscientist and Professor at Danish Institute of Agricultural Sciences in Environmental Technology January 1984 – July 1988 Scientist, Centre of Terrestrial Ecology. National Environmental Research Institute, in Agro-ecology. May 1981 – December 1984 Soil chemist at Environmental Protection Agency, Ministry of Environment.   RESEARCH PROFILE Sven G. Sommer (SGS) is specialist in manure engineering with focus on biowaste and manure management aiming at developing the best possible processes and management for using the biowaste and manure and at the same time reduce pollution from these. The studies carried out include reduction of gas emission (ammonia and greenhouse gases) composting, biogas production. The research has a strong focus on organic matter chemistry and biological and chemical processes related to the transformation of the organic components in manure and gas emission. His research has includes studied of: 1) Chemical processes and microbial activity affecting transformation of the manure and gas emission 2) Composting and biogas production. 3) Development and implementation of efficient and cheap techniques for managing the biomass. 4) System analysis and models of manure management. SGS has broad international research experience from two sabbatical leaves, i.e. one year at Lincoln University in 1994-1995 and half a year in 2015, six months at Agriculture and Agri-Food Canada, Lethbridge (2003) and 3 months at three months at IGER (2011). Through his assignments in Brazil, Malaysia, Thailand, Vietnam, Mozambique, Kirgizstan and China SGS is well equate with collaborating with researchers and end users of the research under very different working conditions. SGS has considerable experience in working in interdisciplinary and cross-cultural teams.   TEACHING EXPERIENCES Associate supervisor of 3 PhD students and supervisor of 7 PhD students. Opponent at the viva of 10 PhD students and more than 10 MSc and BSc evaluations. SGS participated in the course ”Udvikling af undervisning for ansatte ved DJF og GEUS – et kvalificeringsforløb” and ccontributed to the planning and organisation of the Master education Bio-system Engineering at Aarhus University, Faculty of Agricultural Sciences. He has been teaching in the biowaste/manure management and bio-refinery courses, MSc training course in project development, course in sampling and analysing composition of animal manure, elementary chemistry for 1st year students and project based learning course in chemical engineering for visiting students and for 1. Year students.   PUBLICATION & DISSEMINATION ACTIVITY Since 1998 SGS has organised 6 workshops on use of animal manure for plant amelioration and as fertilizer for crops and he has been coordinating the 12th RAMIRAN international Conference in 2006 entitled "Technology for recycling of manure and organic residues in a whole farm-perspective". SGS has been key note speaker, chairman or mediator at 12 international workshops and conferences and is reviewer of articles from 6 international journals and has been editor of Journal of Environmental Quality. Author, senior author and co-author more than 300 publications of which 129 are in international refereed scientific journals, more than 60 are book chapters or conference proceedings and more than 75 are reports, popular articles published in farmers journals etc. The peer reviewed journal papers have been cited 6000 times (ISI) giving a H-index of 45. He has contributed to 49 book chapters or conference proceedings and 100 reports, popular articles published in farmers journals etc. Most publications relate to animal manure, to the development of techniques and management practises, contributing to the reduction of ammonia emission, greenhouse gas emission and the separation of manure to reduce leaching losses.
