Their research topics cover diverse areas such as Geology and Paleoclimatology Research, Mine drainage and remediation techniques, Heavy metals in the environment, Aquatic Ecosystems and Phytoplankton Dynamics, Isotope Analysis in Ecology, Protist diversity and phylogeny, and Arsenic contamination and mitigation.

Recent papers authored or co-authored by Patterson include:

  • The varved succession of Crawford Lake, Milton, Ontario, Canada as a candidate Global boundary Stratotype Section and Point for the Anthropocene series, 2023, The Anthropocene Review
  • Testate Amoeba Functional Traits and Their Use in Paleoecology, 2020, Frontiers in Ecology and Evolution
  • Use of Arcellinida (testate lobose amoebae) arsenic tolerance limits as a novel tool for biomonitoring arsenic contamination in lakes, 2020, Ecological Indicators
  • Intra-Lake Arcellinida (Testate Lobose Amoebae) Response to Winter De-icing Contamination in an Eastern Canada Road-Side "Salt Belt" Lake, 2020, Microbial Ecology
  • A needle in a haystack: A new metabarcoding approach to survey diversity at the species level of Arcellinida (Amoebozoa: Tubulinea), 2023, Molecular Ecology Resources

Patterson frequently collaborates with a number of co-authors, including Nawaf A. Nasser, Jennifer M. Galloway, Carling R. Walsh, Helen Roe, and Francine M.G. McCarthy.

Their publications are commonly found in journals such as:

  • Research Square (Research Square)
  • The Anthropocene Review
  • PeerJ
  • Environments
  • Journal of Paleolimnology

Patterson's research involves detailed study of environmental processes, particularly those related to biotic responses to environmental contamination and stratigraphic studies pertinent to the Anthropocene epoch. The work on Arcellinida (testate lobose amoebae) reflects a focus on bioindicator species to assess pollution levels such as arsenic contamination and road salt impact in aquatic ecosystems.

The blend of expertise in atmospheric science, chemistry, paleoecology, and ecology allows for interdisciplinary approaches to complex environmental questions. Their publication record indicates consistent contributions to the understanding of both natural and anthropogenic changes within aquatic and sedimentary systems.
