The Demas Lab at ABC 2018

This past weekend, Kristyn, Clarissa, Kat, and Jessica gave poster presentations at the 2018 Animal Behavior Conference, an annual meeting hosted by Indiana University’s own Center for the Integrative Study for Animal Behavior (CISAB). Way to go, ladies!

Congratulations, Dr. Kristyn Sylvia!

Today, Kristyn gave a wonderful Ph.D. dissertation seminar entitled, “Modulation of the Neuroendocrine System, Gut Microbiome, and Social Behavior” and successfully defended her dissertation to her committee. Congratulations, Dr. Sylvia!

Greg Receives Daniel J. Ziegler Award

On March 23, Greg was honored with the Daniel J. Ziegler Award by his alma mater, Villanova University. This award is given by the Department of Psychological and Brain Sciences to an alumnus who has made distinguished contributions to the field of psychology, other fields, or society in ways that represent the mission of the department and the university. Congratulations, Greg!

Kat, Greg, and Nikki Publish Mini-Review in Frontiers in Endocrinology

Kat, Greg, and former Demas lab graduate student Nikki Rendon’s mini-review on neural androgen synthesis and aggression in seasonally breeding animals has been accepted for publication in Frontiers in Endocrinology! This paper discusses evidence for a novel neuroendocrine pathway for territorial aggression, in which adrenal dehydroepiandrosterone (DHEA) serves as an important precursor for neurally-derived androgens during the non-breeding season.

A link for the manuscript can be found under the “Publications” page and can also be accessed here.

Kat Awarded Common Themes in Reproductive Diversity (CTRD) NIH Predoctoral Fellowship

Kat was awarded a Common Themes in Reproductive Diversity (CTRD) NIH Predoctoral Fellowship for the 2018-2019 academic year! This fellowship is awarded annually by the Center for the Integrative Study of Animal Behavior (CISAB) at Indiana University to outstanding graduate students whose research focuses on behavior and physiology in animal systems or humans.

Kristyn Publishes Manuscript in Physiological Reports

Kristyn’s manuscript on the influence of acute lipopolysaccharide (LPS) administration on immune system activation and the gut microbiome of male and female hamsters has been accepted for publication in Physiological Reports! In this study, Kristyn showed that a single, modest dose of LPS activates an immune response and reduces food intake and body mass, but does not alter microbial composition or diversity in the gut.

Kristyn Publishes Manuscript in Reproductive Biology

Kristyn’s manuscript on leptin as a predictor of reproductive state in healthy women has been accepted for publication in Reproductive Biology! This study was conducted in collaboration with former Demas Lab post-doc Tierney Lorenz and Dr. Julia Hieman from the Department of Psychological and Brain Sciences.

Kristyn and Greg Publish Microbiome Review

Kristyn and Greg’s microbiome review paper has been accepted for publication in Hormones and Behavior! This review discusses evidence for the role of the gut microbiome in modulating social behavior and addresses potential mechanisms by which the microbiome may be communicating with the brain and immune system to influence behavior.

A link for the manuscript can be found under the “Publications” page and can also be accessed here.

Happy Holidays from the Demas Lab

At the end of finals week for the fall 2017 semester, members and friends of the lab gathered at Greg’s house for our annual Christmas party, featuring delicious home-cooked dishes and a memorable white elephant gift exchange. From all of us at the Demas lab, we wish you a wonderful holiday season!
