My primary areas of interest are the evolution of
diversity of fishes
(especially aulopiform and cyprinodontiform fishes), the anatomy and morphogenesis of
fishes (again... especially the above two groups), the
natural history and conservation of biodiversity, and .
The fishes commonly referred to
as topminnows, killifishes, and "livebearers" comprise the Order
Cyprinodontiformes. These fishes typically live in shallow
freshwaters, brackish waters, and (in a few cases) coastal marine
environments from the temperate zone to the tropics. Approximately one third of the species in this order are viviparous
("livebearing") and give birth to free swimming young rather than laying eggs.
My past work on the diversification of this group has included studies of
the onesided livebearers and foureyed fishes (Family Anablepidae), the
North American topminnows and killifishes (Family Fundulidae), and the
livebearers (Family Poeciliidae). Most of these studies have focused
on recognzing and using morphological variation to infer the evolutionary
history of the groups and explore patterns of evolution of various
characetristics in these groups (e.g., viviparity, salinity tolerance).
In addition to the work exploring evolution within cyprinodontiform
fishes, I also am working on deep sea aulopiform fishes with M. P. Davis
at the Field Museum of Natural History. Specifically we currently
are exploring light-producing organ morphology in barracudinas (Family
Paralepididae) and diversification of the tripodfishes, spiderfishes, and
relatives (Family Ipnopidae).
