Draft:Leonard I. Wassenaar
| Submission declined on 14 June 2025 by Fancy Refrigerator (talk). This submission's references do not show that the subject qualifies for a Wikipedia article—that is, they do not show significant coverage (not just passing mentions) about the subject in published, reliable, secondary sources that are independent of the subject (see the guidelines on the notability of people). Before any resubmission, additional references meeting these criteria should be added (see technical help and learn about mistakes to avoid when addressing this issue). If no additional references exist, the subject is not suitable for Wikipedia. The content of this submission includes material that does not meet Wikipedia's minimum standard for inline citations. Please cite your sources using footnotes. For instructions on how to do this, please see Referencing for beginners. Thank you.

Leonard I. Wassenaar is a Canadian geochemist and isotope hydrologist best known for his work on the environmental applications of stable and radioactive isotopes. He is currently the Executive Director of the Andre E. Lalonde Accelerator Mass Spectrometry (AMS) Laboratory at the University of Ottawa.
Education
[edit]Wassenaar received his B.Sc. in geology from Calvin University in 1983, followed by an M.Sc. from Brock University in 1986 with a focus on Champlain Sea paleoecology. He completed his Ph.D. in geochemistry and isotope hydrology at the University of Waterloo in 1990. He later held a postdoctoral fellowship at the Institute for Hydrology in Munich, Germany.
Career
[edit]From 1991 to 2012, Wassenaar worked at Environment Canada in Saskatoon, where he served as a senior research scientist and directed the Stable Isotope Hydrology and Ecology Laboratory. He joined the International Atomic Energy Agency (IAEA) in 2012, where he was Team Leader of the Isotope Hydrology Laboratory and later Head of the Water Resources Section until 2021.
In 2024, he was appointed Executive Director of the Andre E. Lalonde AMS and Radioisotope Laboratory at the University of Ottawa. He has also held adjunct or visiting professorships at the University of Saskatchewan, Danube University Krems, and the University of Ottawa.
Research
[edit]Wassenaar's work has centered on using isotopic tools to trace water sources, food web dynamics, and animal migration. He has made significant contributions to tritium detection, nitrate source tracking, and isotope fractionation methods in hydrology and ecology. He co-authored the textbook Tracking Animal Migration Using Stable Isotopes, now in its second edition (Elsevier, 2018).[1]
He has published over 280 peer-reviewed journal articles and has an h-index of 74 with more than 20,000 citations, according to Google Scholar.[2]
Editorial and Professional Roles
[edit]Wassenaar is a Co-Editor of Isotopes in Environmental and Health Studies and an Associate Editor at PeerJ.[3] He is the founder of the International Conference on Applications of Stable Isotope Techniques to Ecological Studies (IsoEcol), launched in 1998.
