Dr. Blomster's regional and spatial research interests lie primarily in Mesoamerica, where he has focused on Mixtec, Zapotec, and Olmec cultures. He has conducted archaeological and laboratory fieldwork at Etlatongo, in the Mixteca Alta of Oaxaca, Mexico, which examines the emergence of social complexity in the Nochixtlán Valley, and explores the impact of interregional interaction in this area. His academic writings have focused on manipulation and movement of style, looking at both traditional stylistic analyses as well as compositional approaches.
Early Formative socio-political complexity and interaction, especially the role of the Olmec. Ongoing laboratory analyses, with additional excavations to come, to understand the nature of both local and non-local ceramic and figurine traditions, and interaction's impact on socio-political complexity.
Diachronic change in urbanism and pottery production in Oaxaca. Research devoted to defining a new ceramic phase, the Yucuita (from 500 – 300 BCE), for the Mixteca Alta, and investigate the related but different processes of urbanism, specialization, and standardization.
Sociopolitical collapse and transformation in Oaxaca following the collapse of major Zapotec and Mixtec states around 800 CE.
