What we do
The diversity of animal behavior is fascinating, yet we know little about how behavior evolves.
We take genetic, genomic, molecular, and neurobiological approaches to understand the mechanisms underlying the natural variation and evolution of behavior.
Our work focuses mostly on exploratory and social behaviors – like pair bonding and parental care – in Peromyscus mice, and on aggression in Siamese Fighting Fish (Betta splendens).

Lab Manager and Research Assistant
Kerel received his MSc in Neuroscience from the University of Bremen. Currently he is working in collaboration with the Kӧnig lab at the University of Zurich whose aim is to understand the evolution of social behavior in mice.
Alec received his BA from Oberlin College studying Neuroscience and Hispanic Studies. He is currently working on developing genetically modified Betta fish and helps coordinating the fish facility.
Amy received her PhD from Columbia University and her BSc from MIT. She is studying the neural basis of sexually dimorphic behaviors in Betta splendens.
Chris received his PhD from KIT and was a postdoc in Filippo Del Bene's lab in Paris. He aims to understand the neural basis of differences in parental care behavior in Peromyscus.
Pei received her PhD from Caltech working in the lab of Paul Sternberg. She is studying the genetic basis of aggression in Betta splendens.
Jenny received her PhD from Emory University. She is studying the neural and genetic mechanisms of alternative life histories in closely related species of Peromyscus.
PhD Student (E3B program)
Natalie got her BSc from Rice University and a masters in evolutionary biology from the University of Amsterdam. She is studying the genetic basis of anxiety and exploration in Peromyscus mice.
PhD Student (NBB program)
Claire received her BA from Barnard College. She is studying the visual cues critical for evoking aggression in Betta splendens. She is also interested in the neural circuits underlying Betta visual processing of aggression-inducing stimuli.
PhD Student (NBB program)
Kim is a PhD student in the lab jointly supervised by Andrés and Steven Siegelbaum.
PhD Student (E3B program)
Wyatt received his B.Sc. from Concordia University and his M.Sc. from McGill University. He is interested in the evolution of molecular mechanisms underlying adaptive phenotypes.
Julio is a dachshund and really good at detecting and retrieving food (that belongs to others).
