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.

The Cusick lab has arrived in Utah! I am so excited to start as Assistant Professor at
Utah Valley University! I am looking forward to teaching and building my research lab!
Stay tuned for more exciting updates!
And what an exciting welcome to Utah! My first moose sighting right here in Park City!
Congratulations Luke! Luke spent the summer as an REU researcher at the University of Nebraska! He won Best Poster Presentation for the Systems Biology of Plant and Microbiome REU Program and placed in the top 5 poster presentations for all summer research programs across the university, which consisted of approximately 100 presenters! Way to go!
Lots of exciting things happened this summer. Check it all out below!
Congratulations to Kate Adaniya for publishing her first first-author paper from her
undergraduate work. Kate investigated individual consistency in social and escape
behaviors across developmental stages using Siberian hamsters.
Check out the paper here:

It was wonderful being a part of the ABS 2021 Virtual Meeting this year! As a
member of the ABS Diversity Committee, we planned a incredible workshop: Becoming
a J.E.D.I. Mentor, which was a huge success. It was also wonderful to present work from
my NIH CTRD Postdoc at Indiana University. Thanks to everyone for a great conference!
I am thrilled to announce that I will be starting as Assistant Professor at Utah Valley University this fall! I look forward to starting my lab and teaching!

Thrilled to have two undergraduate students present posters at Indiana University Bloomington's Animal Behavior Virtual Conference! Kate presented her undergraduate research from her independent study investigating consistency in behavior across time. Luke presented his undergraduate work investigating the interactive effects of photoperiod, stress, and gut microbiome manipulations on adult behavior.
It was a pleasure speaking about my research and careers in academia with the students of the Biology Seminar at CSULB.
Another experiment complete! Congratulations Luke for completing your first independent undergraduate experiment.
It was such an honor to be invited to give a *virtual* talk for the Hastings Plenary Lectureship Series. I had a great time and got great questions! The best part of this invite was that it came from my previous undergraduate student Cesar Estien. It is so exciting to see all that he has accomplished!
What a summer! I was thrilled to co-organize the Animal Behavior Society's first virtual meeting! It was a huge success! I was so excited to present my most recent postdoctoral research. In addition, Kate presented her undergraduate research from her independent study investigating consistency in behavior across time.
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!
Check out the popular press summary of the work here
Check out our newest publication! "Murder Mystery at the Nest of a Brown-headed Nuthatch (Sitta pusilla) in the Florida Field Naturalist!

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!
