Professional Affiliations:
Elected Council Member and Chair of Membership for the Wilson Ornithological Society (2010-2013)

Certified Bird Banding Trainer, North American Bird Banding Council

Board Member and scientific advisor (and Past President and Vice President) for the Board of Directors for the Braddock Bay Bird Observatory since 2000. Bird Observatory (www.bbbo.org) is a non-profit organization dedicated to ornithological research, education and conservation. Our primary mission is to monitor migration of songbirds during fall and spring migration on the south shore of Lake Ontario near Braddock Bay (near Rochester, NY).

Advisor to The Nature Conservancy of Central and Western NY to help identify and characterize the quality of specific stopover habitats for migratory birds in the Lake Ontario basin.

Personal Statement:
I am interested in several research areas that revolve around a curiosity about animal migration and sensory biology. Animals use a variety of cues for finding their way and determining their location during migration and daily movements. I have largely studied the role of the earth's magnetic field in animal orientation.

For more than 50 years, scientists have known that many animals are capable sensing the earth's magnetic field (a sense that has been labeled "magnetoreception"), but we don't fully understand how animals use the magnetic field for migration. In addition, the underlying physiological, or sensory mechanisms, for magnetoreception have yet to be identified. In other words, we don't quite know how animals sense the earth's magnetic field! I have conducted experiments on migratory birds, amphibians (yes, they migrate too), and even on rodents to gain a better understanding of how animals use and sense the earth's magnetic field.

I am also interested in how animals sense and use visual cues in the sky for migration. Many animals use star patterns or the position of the sun to determine direction, but animals can also use cues that humans don't see in the sky. In particular, there are patterns of polarized-light in the sky that many animals can use to determine direction. In vertebrates, it appears that polarized light in the ultraviolet (UV) part of spectrum is important for orientation. For birds, polarized light information around sunrise and sunset is a particularly salient orientation cue. In addition UV light, and the ability to perceive it, is important for many other behaviors in animals such as prey-capture, foraging, and mate selection. I have studied UV visual perception in amphibians, fish and insects, and I have explored patterns of ultraviolet reflectance in the plumage of songbirds.

My scientific studies have led me to interesting places such as Australia, British Columbia, Mexico, and Trinidad and Tobago. I have also had the pleasure of working with a great variety of amazing animals including bobolinks and many other North American song birds, Australian silvereyes, oilbirds and nighthawks, rainbow trout, pacific salmon, Siberian Hamsters, bats, Red-spotted newts, axolotls, and an insect known as a thrip. Biological research has been a wonderful way for me to connect with and learn about the natural world.
