Thor's research interests include birds, plants, primates, insects, endangered species, and the interface between human and natural systems. He has studied the effects of habitat fragmentation on rare plant communities, avian nest predation, and the reproductive ecology and genetic diversity of rainforest trees. Thor is currently pursuing projects on Tufted Puffins, native bees, and rare butterflies, and is involved in an international effort to assess the ecological impacts of warfare. His work on the occurrence of warfare in biodiversity hotspots was covered by news outlets around the world, including Reuters, Scientific American, The New York Times, and The Times of India.
