Alan’s projects center around the herpetofauna (amphibians and reptiles) of the Chicago area, particularly in the post-industrial landscape of the Calumet Region in northwest Indiana and southeastern Chicago. In cooperation with the National Park Service, U.S. EPA, Indiana Department of Natural Resources and The Nature Conservancy, he studies the distribution, ecology and conservation of this herpetofauna. In spite of large scale habitat disruption and destruction, there are still sizable remnants left of the patchwork of habitats that make the region unique.

Private meteorite collector and Collections & Research Committee member Terry Boudreaux donated to the Field Museum two specimens of the iron meteorite Gebel Kamil that formed a 45-m-wide impact crater in the southwestern corner of Egypt (East Uweinat Desert) near the Sudanese and Lybian border. The crater was discovered through Google Earth in 2009 on a Cretaceous sandstone surface; the impact occurred less than 5000 years ago as reported in a recent article in Geology.

Bryozoan zooidmodules interact with other units and are integrated both within themselves and in an inclusive whole. They originate from budding loci and differentiate as populations of cells. However, they are also inclusive of another level of modularity, in that organs differentiate as entities or parts of the zooids. Both levels of modularity can be individuated using key criteria of evolutionary developmental biology. Read more about Evolution and ecology in modular organisms
How to conduct a quick survey of a large, systematically arranged, invertebrate paleontology collection at the Field Museum to learn how many specimens in the collection are from the Michigan Basin.

A major research focus of my laboratory is the locomotor biology of fishes that generate forward propulsion by oscillating and undulating the fins. We ask the questions: How are fishes designed to swim efficiently and with such high maneuverability? How are the muscle-tendon-bone systems that provide thrust coordinated by neuromotor control? How has locomotion evolved in complex 3-dimensional coral reef environments? Techniques used in locomotor biomechanics include kinematics, electromyography, sonomicrometery, and modeling of the biomechanics and hydrodynamics of locomotion.

Fish feeding biology is a well-established model system for the study of biomechanics, physiology, and comparative diversity. In this lab, we are developing biomechanical models of complex feeding movements in coral reef fishes to test new hypotheses for the mechanism of jaw opening and upper jaw protrusion in fishes. Models include four mechanisms of feeding mechanics in seven labrid fish species (Westneat 1990; 1994), the highlight of which is the spectacular jaw mechanism of the sling-jaw wrasse (Westneat 1991). In addition to proposing novel feeding mechanisms, this research allowed an evolutionary analysis of biomechanics in fishes (Westneat, 1995).

A major challenge in biology is the resolution of phylogenetic relationships among diverse clades of fishes inhabiting coral reefs around the world. Collections are obtained through an active field program of visiting coral reefs in the Philippines, Papua New Guinea, Australia, and Pacific Islands, as well as the Caribbean, collecting fishes using SCUBA diving, nets and working with fishermen. Phylogenetic systematics is the generation of molecular and morphological data from those collections, followed by large-scale data analysis to yield phylogenetic trees, which represent our best estimate of the family tree of relationships among fish species. Generating phylogenetic trees is one of the most useful and exciting areas in biology today. Read more about Phylogenetic Systematics of Coral Reef Fishes
