His studies in Feather integrate themes in fields like Wildlife, Setophaga and Taiga.
He has included themes like Salinity, Nitrate and Nitrification in his Groundwater study.
His studies deal with areas such as Animal migration, Oxygen-18 and δ18O as well as Isoscapes.
His Hydrology study combines topics in areas such as Dissolved organic carbon, Prairie lake and Seasonality.
His most cited work include:
- Global application of stable hydrogen and oxygen isotopes to wildlife forensics. (708 citations)
- Comparative equilibration and online technique for determination of non-exchangeable hydrogen of keratins for use in animal migration studies. (507 citations)
- Linking breeding and wintering grounds of neotropical migrant songbirds using stable hydrogen isotopic analysis of feathers. (449 citations)
What are the main themes of his work throughout his whole career to date?
His primary areas of investigation include Ecology, Environmental chemistry, Hydrology, δ18O and Aquifer.
His Ecology research incorporates elements of Isoscapes and δ13C, δ15N.
The various areas that he examines in his Environmental chemistry study include Isotopes of carbon, Effluent, Isotope analysis, Isotopes of oxygen and Isotope fractionation.
While the research belongs to areas of Hydrology, Leonard I. Wassenaar spends his time largely on the problem of Nitrate, intersecting his research to questions surrounding Denitrification and Manure.
His study in δ18O is interdisciplinary in nature, drawing from both Fractionation, Nutrient and Analytical chemistry.
His Aquifer research is multidisciplinary, incorporating perspectives in Geochemistry, Pore water pressure, Dissolved organic carbon and Geomorphology.

In recent papers he was focusing on the following fields of study:
Ecology, δ18O, Environmental chemistry, Hydrology and Analytical chemistry are his primary areas of study.
When carried out as part of a general Ecology research project, his work on Range, Overwintering and Feather is frequently linked to work in Ophryocystis elektroscirrha, therefore connecting diverse disciplines of study.
His δ18O research incorporates themes from Isoscapes, Atmospheric circulation, Northern Hemisphere, Atmospheric sciences and Southern Hemisphere.
The concepts of his Environmental chemistry study are interwoven with issues in Isotopes of nitrogen, Isotope fractionation, Isotope analysis, δ15N and Isotopes of oxygen.
Leonard I. Wassenaar interconnects Fertilizer and Manure in the investigation of issues within Hydrology.
His work in the fields of Isotope-ratio mass spectrometry, Mass spectrometry and Laser spectrometry overlaps with other areas such as Materials science and Spectrometer.
