James spent the first portion of his research career at UC San Diego documenting patterns of bee biodiversity degradation in fragmented landscape of southwestern San Diego County. He is currently examining how these patterns of bee species loss influences plant-pollinator interaction network structure and the quality of pollination services bees provide to native plant species in these habitat fragments.

James is currently also working on producing an inventory of the native bees species of San Diego County, a hotspot of bee diversity that has received relatively little attention from bee biologists in the past. James's surveys in the scrub and desert habitat of San Diego has thus far yielded at least 6 new species and dozens of new records for the County. He is now working closely with taxonomists to describe the new species discovered in his surveys.

James's previous projects at the Holway lab include using trap-nests and stable isotopes to examine the foraging ecology of bee species living in urban-scrub mosaic habitats, and investigating how the eye color of bees relates to their ecology and phylogeny. During his undergraduate career, James studied neutral community dynamics in damselflies, distribution of aquatic insect larvae in stream systems punctuated by beaver ponds, and effects of habitat fragmentation on native and exotic bees.
