I think I became a scientist because I like problem solving and figuring out how to do difficult things. So tracking small birds across very large distances fits the bill. Much of my research has to do with the migrations of songbirds, and I am interested in all aspects of this behavior, from physiology to speciation. In addition to birds I have an affinity from gadgets. In my lab we often construct our own research tools, including geolocators, radio transmitters, rfid readers, and things that have no name as of yet. We also like to share our designs with other researchers, so shoot us an email if you have an idea or an application you want to try.

In 2012, Heather received her B.S. in Wildlife Ecology and Conservation from the University of Florida. Following graduation she worked as a biological field technician on a variety of avian projects. Her work in Oklahoma with Dr. Alex Jahn concerning migration of tyrant flycatchers led to her meeting Dr. Bridge and becoming interested in his work using geolocators to track long-distance migrants. In the fall of 2016 she began her M.S. studies in the Bridge lab. Currently she is looking into whether heavy metal contamination (e.g. lead, cadmium, zinc) affects the memory and associative learning capabilities of wild songbirds. Her study site is the Tar Creek Superfund Site (TCSS) in northeastern Oklahoma. She plans to use Radio Frequency Identification (RFID) enabled specialized food dispensers (“smart feeders”) to attract, monitor, and test common feeder birds at TCSS and compare the results with those of birds at non-contaminated reference sites.

Kate working in the Peruvian Amazon 2017

Kate is an ecologist with a background in marine biology, vertebrate physiology, and movement ecology. She completed a double BS degree in marine biology and zoology at Humboldt State University in Northern California, and received an MS in ecology from San Diego State University. Kate’s focus has always been on coastal nesting birds including skimmers and their allies. She is currently pursuing a doctorate focused on life history strategies of skimmers and terns in North America and the Amazon. Her dissertation topics focus upon river-beach nesting waterbirds and the tradeoffs these species develop when faced with predation threat, flooding threat, extreme temperatures, and impacts to reproductive success. She is also working on a comparative analysis of Black Skimmer wing morphology across a latitudinal gradient to explore relationships between functional morphology and migration strategy.

William Oakley

The purpose of Will’s dissertation research is to test hypotheses and provide knowledge on how individual birds move and disperse through human-altered landscapes and how they select particular habitats during the non-breeding season.
For his dissertation research, he will focus on 1) the winter site fidelity and functional connectivity of Seaside, Saltmarsh, and Nelson’s Sparrows and 2) the post-breeding communal roosting behavior of Purple Martin. The data acquired from this research is essential for successfully predicting species’ responses to impacts of land-use and/or climate change as well as making informed conservation decisions. Methods: Manipulative and non-manipulative field-based experiments coupled with radio-tracking methods; computer-based modeling (e.g. individual-based models).

Meelyn Mayank Pandit

Contact Email
Meelyn is a first year PhD student at the OK Biological Survey. His interest in birds and behavioral ecology began when he joined the Ketterson Lab at Indiana University as a Cox Research Scholar where he studied the differences in singing behavior between city and montane Oregon juncos. He then obtained his master’s degree at Oklahoma State University, where he studied how anthropogenic noise affected relationships between behaviors in eastern bluebirds. His goal at OU is to integrate microtechnology, such as the Raspberry Pi computer and geolocators, into field biology to study eastern bluebird parental care and migratory behavior, respectively. Other research interests include migratory systems, ecological factors that affect avian singing behavior, and using wildlife as a teaching tool for K-12 students


Postdoctoral Researchers

Wesley T. Honeycutt

Contact Email

Wes is a technologist who specializes in physical chemistry, electronics, and device design. His current research interests include the application of sensing technologies to difficult scientific challenges. In the Bridge lab, this involves designing autonomous turrets for observation, precision reward dispensers for behavioral studies, coming up with novel ideas in his lab. Wes has a strong commitment to inter-disciplinary pursuits by experience working with engineers, scientists, and business-people across several projects. His Ph.D. work at OSU focused on the development of gas microseepage sensors for carbon sequestration sites at oil extraction sites, as well as side projects on environmental uranium adsorption, peroxide explosives detection, and personal air-quality sensor design.


Jackson Helms


Jackson’s research focuses on ants, but unlike many ant biologists Jackson has turned his lens upward to address questions relating to the winged queens and drones that are responsible for reproduction and dispersal in most ant species. His work proposes a new hypothesis (the Found or Fly Hypothesis) to explain how ant queens negotiate tradeoffs associated with dispersal ability and their capacity to initiate a new colony. Jackson’s endeavors in support of this hypothesis have ranged from basic natural history discoveries (how long can ant’s fly?) to spatially explicit models of alternative dispersal strategies. His work touches on the fundamentals of life-history theory as well as the emerging field of aeroecology. Before he became a scientist Jackson was a marine and fought in the Iraq War. Jackson’s blog “Marine to Myrmecologist” tells the story of his adventurous career path.  Jackson Graduated with a Ph.D. in the spring of 2016.  He is currently a Post-doctoral Research Associate working for Nick Haddad at Michigan State University’s W.K. Kellogg Biological Station studying interactions between habitat fragmentation, insect dispersal, and ecosystem services.

Carmen is a computer scientist specializing in machine learning. She enjoys playing with data and working on challenging problems. She graduated with her master’s degree in December 2017 with a thesis that focused on automated bird roost detection using NEXRAD radar data. She built a convolutional neural network that was able to determine whether an individual NEXRAD radar could see a bird roost at a given time step with 90 percent accuracy. At the Bridge Lab she is trying to improve upon her master’s research by using machine learning to find exactly where in the radar image the bird roosts are located. Her previous work experience includes developing educational video games, applied research on educational video game data, and applied machine learning at Google’s android location and context research team.


Jeff Kelly – University of Oklahoma


Jeff is Director of the Oklahoma Biological Survey and is the academic father of the Bridge Lab–that is, he was my post-doc advisor. We collaborate with Jeff in some way on just about everything. Jeff is one of the founders of Aeroecology as an academic discipline and leads an NSF funded National Research Traineeship at OU that uses Aeroecology as a proving ground for training interdisciplinary scientists. Jeff studies bird migration and is currently focusing on ways to combine a variety of data sources (e.g. weather radar, eBird, and satellite remote sensing) to observe and explain continental scale migration phenomena.

Rosemary Knapp – University of Oklahoma


Rosemary teaches Principles of Physiology every other semester, and we collaborate on generating new course material (including the online coursebook) and generally making the course better each year. In 2015 we offered Principles of Physiology as a Presidential Dream Course and brought in guest speakers from the US and the UK as well as OU to interact with the class.

Vladimir Pravosudov – University of Nevada, Reno


Vladimir is leading an investigation into the cognitive abilities of food caching birds (e.g., Mountain Chickadees) in environments that differ in terms of harshness. He is testing the basic idea that harsher environments will select for individuals with better long term memories that allow them to recover more cached food. His current project makes extensive use of RFID enabled bird feeders, which is where we come in.

John Eadie – University of California, Davis


John is using RFID technology to monitor brood parasitism (i.e., females laying eggs in nests of other females) among Wood Ducks in northern California. By tagging individuals with RFID transponders and putting readers on nest boxes, John is tracking individual brood parasitism activity and looking at relatedness among the egg dumpers and the recipients. Maybe the burden of raising someone else’s ducklings is tempered by the fact that the other female is a relative.

Ellen Ketterson – Indiana University

We wkettersonFieldork with Ellen and her Post-docs Adam Fudickar and Jonathan Atwell on migratory genomics. We have carried out RNAseq analyses to look at gene expression in tissues from both migratory and non-migratory Dark-eyed Juncos that winter in the same location. We found differential expression in hundreds of genes in both blood and muscle (details here).
