Research Focuses

Anatomy and biomechanics of the masticatory system
Evolution of feeding adaptations in primates
Material and structural properties of primate foods
Craniomandibular morphology of Eocene primates
Miocene platyrrhine dietary adaptatons

I am interested in the link between skull form and diet. How do food properties influence skull morphology over evolutionary time and are there skull features we can use to reconstruct diet in extinct mammals? In particular, I am excited about the context for the evolution of primates and I am curious about whether changes in diet prompted changes to the skull that characterize the first primates. To address these interests, I look at links between the dimensions of the chewing muscles, bony skull features, and food properties in extant primates. I use these links to reconstruct aspects of feeding and diet in extinct primates. I am interested in applying these techniques more broadly and generating dietary hypotheses for other groups of extinct mammals. In addition, I participate in several field projects to recover fossil mammals from localities across the world. I and my colleagues perform non-invasive, observational feeding experiments on captive primates to quantify feeding behavior. This research program is driven by a desire to understand the ways in which our earliest primate ancestors related to their environment.

Currently I run two funded projects that incorporate graduate and undergraduate students. They are detailed below. I encourage my students to participate in field and lab research. I also encourage them to think of and test their own scientific questions.

Funded Project 1: “Monkeys on the Edge: Ecological Change in a Mammalian Community across the Mid-Miocene Climatic Optimum in Extreme Southern Patagonia” (NSF BCS 1749307).

Funded Project 2: “Experimental Paleontology: Evaluating the Function of Primate Teeth by Testing them against Real Foods”
