Nawaf Nasser is a Research Associate specializing in micropaleontology, contaminant geochemistry, and multivariate statistics. His research focuses on utilizing various proxies (e.g. micropaleontological, geochemical, and sedimentological) to assess the impact of environmental contamination and the success of remediation efforts in northern lakes. Nasser has a B.Sc. in Geology (with marine science minor) from Kuwait University, and a M.Sc. and Ph.D. in Earth Sciences from 杏吧原创 University, where he investigated the spatial response of Arcellinida, a group of shelled benthic protists, to mining-related contamination in lakes in the area of Yellowknife, Northwest Territories, Canada.

Nasser’s Ph.D. research work was focused on further developing Arcellinida a geoscience tool for environmental monitoring and risk assessment by:

1. Identifying environmental controls on the spatio-temporal distribution of Arcellinida (testate loboese amoebae) in lakes impact by anthropogenic contamination in regions of high natural resource potential (e.g. gold mining across the prospective Great Slave Geological Province, Northwest Territories, Canada.
2. Understand how Arcellinida taxa interact with elements of environmental concern, particularly focusing on arsenic.
3. Quantifying the tolerance limits of different Arcellinida taxa to varying levels of arsenic contamination in impacted lakes in the Canadian sub-Arctic.
4. Developing novel Arcellinida sample-preparation protocols enhancing the speed, efficiency, and accuracy of micropaleontological analysis.
