Olof Andrén: Ecology, Environmental Conservation & Soil Biology
Professor, Soil Biology/ Agriculture; Docent, Environmental Conservation
I have a BSc from Uppsala University in Sweden, and a PhD as well as "Docent" grade from SLU. Between 1976 and 2011 I worked at SLU, Swedish University of Agricultural Sciences. I resigned in 2011 from a permanent position as Faculty Professor in Soil Biology/Agriculture, which I had accepted in 1994.
I am available as consultant, co-worker, co-author, co-applicant, evaluator etc., in the fields of ecology, agriculture, soil biology, soil carbon modelling, soil biodiversity - or science in general. My CV and publication list will give hints to what I can assist with.
I have worked with the Cold and Arid Regions Environmental and Engineering Institute, Chinese Academy of Sciences (CAREERI), Lanzhou, China, where I held a 'Visiting Professorship for Senior International Scientists', i.e., I worked in China for at least three months per year until 2014. I also worked with IITA and formerly TSBF in Nairobi, Kenya.
I am Associate Editor for the journal Ambio (by the the Royal Swedish Academy of Sciences) and member of the Editorial Board for Journal of Arid Land (China).
2014 - 2016 I was consulting for CarbonWealth/SkyMining on catching carbon dioxide in rapidly growing grass in the tropics, and presently starting up cooperation with other companies. Also consulting and gathering practical experience in solar heating and solar electricity generation - in Sweden and in the tropics.
- Written +100 reviewed papers in scientific journals, books and encyclopedias
- Supervised +15 doctoral students
- Initiator and leader, numerous research projects in Sweden, China, and Kenya
- Section Leader, co-Director etc. for various SLU constellations
- Reviewer, associate editor, consultant for hundreds of papers in scientific journals
- EU, IPCC evaluator and contributor to guidelines etc. Evaluated African Universities for the World Bank in 2015.
- Co-developer of ICBM (Introductory Carbon Balance Model, with Prof T Kätterer), a model used for agricultural soil carbon reporting for IPCC in Sweden, Canada (not IPCC), USA, Norway and China (in progress)
- SAS and Excel programming for statistics, modelling and presentation (400+ programs) .
- Also the free statistical package R, for ICBM programming.
- Invited speaker/organizer to international conferences in France, USA, Australia, Sweden
- Languages: Swedish, English (scientific), some German, a little French, minor Swahili, a few words in Chinese...
- Licensed pistol shooter & gym instructor, Coastal Skipper, Marine radio, motorcycle driver etc.
I can work at an hourly fee, e.g., for correcting clarity and logic of scientific papers, or an agreed contract for longer periods.
