Their work addressed key themes in species distribution and climate change, ecology and vegetation dynamics, wildlife ecology and conservation, fish ecology and management, marine and fisheries research, fish biology, ecology and behavior, and wildlife-road interactions and conservation.

Among the frequent venues where Collen's research was published were Biological Conservation, Frontiers in Marine Science, Nature Ecology & Evolution, Functional Ecology, and Hydrobiologia.

The following are examples of recent papers that included Collen's involvement:

  • Complex long-term biodiversity change among invertebrates, bryophytes and lichens (2020), published in Nature Ecology & Evolution
  • Global effects of land use on biodiversity differ among functional groups (2020), published in Functional Ecology
  • The conservation status of the world's freshwater molluscs (2020), published in Hydrobiologia
  • Monitoring extinction risk and threats of the world's fishes based on the Sampled Red List Index (2022), published in Reviews in Fish Biology and Fisheries
  • Strict protected areas are essential for the conservation of larger and threatened mammals in a priority region of the Brazilian Cerrado (2020), published in Biological Conservation

They frequently collaborated with other researchers, including Monika Böhm, Craig Hilton-Taylor, Robin Freeman, Nadia I. Richman, and Caroline M. Pollock.
