Overview

Dr. Huttenlocker is an Associate Professor in the Department of Integrative Anatomical Sciences where he directs graduate courses in Microscopic Anatomy (IAS 511A & 511B) and serves as the Microanatomy discipline coordinator for Years I & II medical students. He received his PhD from the University of Washington in 2013 and held a National Science Foundation-funded postdoctoral fellowship in comparative vertebrate physiology at The University of Utah from 2013 to 2016.

The Huttenlocker lab at USC investigates the origins of mammalian skeletal function, and applies hard-tissue histology & biomedical imaging techniques to modern and fossil bone in order to interrogate the complex origins of mammalian behavior, growth, and endothermic physiology (warm-bloodedness). The lab also utilizes polarized light microscopy techniques to study collagen fiber orientation in bone and its relevance to bone behavior & function. The lab conducts regular paleontological fieldwork in the southwestern United States (funded by NSF and the Department of the Interior) and southern Africa (NSF and South Africa’s National Research Foundation). Dr. Huttenlocker’s teaching philosophy emphasizes shared patterns in vertebrate development & evolution that explain how & why the body functions the way it does.
