My research links behavior, ecology, physiology, microbiology, and evolutionary biology to investigate the developmental processes and mechanisms that affect within-population variation in behavior. Using an integrative approach that combines experimental research in the field and laboratory with microbial, physiological and genetic techniques, I aim to understand how genetic, physiological, and environmental cues interact to influence individual variation in behavior. My areas of focus include cooperation, aggression, and reproduction. I select the system that is appropriate for my research questions and as a result I have worked with a variety of different organisms, including marine mammals, fish, birds, and rodents. I am always excited to learn and investigate interesting questions in a new system.
Commitment to Diversity, Equity, and Inclusion
Diverse perspectives improve the quality and impact of science and society. I am committed to increasing the sociocultural and racial diversity in biology and to providing an inclusive environment, in which everyone has equal opportunity to learn and conduct research regardless of background, race, ethnicity, religion, age, gender, gender expression, sexual orientation, or ability.
I support equality in STEM fields.
News and Announcements
A successful Twitter takeover! I took over the Animal Behavior Society's Twitter for the day. I posted about my research, outreach and more! Gained some new followers and 23,000 views of the work! Follow me on Twitter and see some of the tweets below:
A successful outreach event at our local elementary school's STEAM night. We taught kids about different forms of maternal care, including how mother hamsters will retrieve their pups if they escape from the nest. Kids raced to see how many "escaped" baby hamsters they could bring back to the nest!
Finished my first experiment as a postdoctoral researcher at IU. This 5 month long study investigated how the maternal neuroendocrine-microbiome environment shapes offspring development.
I am thrilled to join Indiana University as a NIH-Funded Common Themes in Reproductive Diversity Postdoctoral Fellow in the Greg Demas and Cara Wellman labs. This postdoctoral position supports my work investigating how maternal neuroendocrine-microbiome environment shapes offspring development and behavior in the Siberian hamster (Phodopus sungorus).
I had so much fun participating in the Allee Competition at the 2019 Behaviour Meeting in Chicago! Incredible science and incredible colleagues.
Graduated from Florida State University with my PhD! Such an amazing experience and lots of hard work!
Successfully defended my dissertation! I have spent so many years investigating the proximate mechanisms of individual variation in cooperation and have found some really interesting results. Stay tuned and keep an eye out for publications this summer!

So excited to announce our newest publication "Manipulated sex ratios alter group structure and cooperation in the brown-headed nuthatch" published in Behavioral Ecology. We experimentally induced changes to the occurrence of cooperative breeding behavior in a wild bird by cross-fostering chicks, which altered the adult sex ratio in the population! Very excited about this work!

I had a great time presenting at the Animal Behavior Society and the International Society for Behavioral Ecology conferences this summer. A lot of great science is happening!
I am so excited and honored to receive an American Association of University Women (AAUW) dissertation fellowship! With this fellowship I will be able to focus on writing my dissertation and publishing in my final year!
I presented my Three Minute Thesis (3MT) talk at Westminster Oaks and was able to meet and chat with some incredible people about the research at Florida State University.
The first chapter of my dissertation has been published in Behavioral Ecology and Sociobiology! Check it out: How do helpers help? Helper contributions throughout the nesting cycle in the cooperatively breeding brown-headed nuthatch
Welcoming Cesar and Stasia to the BHNU team. Cesar and Stasia are undergraduate students at Florida State University. They will be scoring video of brown-headed nuthatch chick fledging behavior. My dissertation research investigates how variation in behavior and physiology as chicks leads to variation in cooperative behavior in adulthood.
Check out all the amazing People who have helped and contributed to the research
Came in 2nd place at Florida State University's Three-Minute Thesis (3MT) Competition. What an incredible experience! It's not easy to summarize six years of research into three minutes and only one slide!
