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).
Bendesky Lab, May 2019
Andrés got his MD from UNAM, Mexico, his PhD from Rockefeller University, and was a Helen Hay Whitney Fellow at Harvard. He is interested in how complex behaviors are generated by the brain and how they evolve.
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.
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.
Madison received her BA from Barnard College and completed her senior thesis in the Bendesky lab. She now coordinates the Betta facility and is working to develop genetically modified Betta fish.
Magdalen is a student at Barnard College. She is studying visually evoked aggression in Betta fish and how social isolation can modulate this process.
PhD Student (NB 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.
Emily is a student at Barnard College. She is studying how the brain and periphery interact to shape exploratory behavior.
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.
Young Mi Kwon
Young Mi got her BS from Harvard and her masters from the University of Cambridge, UK. She is studying genetics in Betta fish.
Christoph received his PhD from KIT and was a postdoc in the lab of Filippo Del Bene. He aims to understand the neural basis of differences in parental care behavior display in several Peromyscus species.
Graduate student (E3B program)
Hiroki got his BA from ICU. He is studying the genetic basis of aggressive behavior in Betta fish. He is interested in the genetic basis and evolution of complex traits.
Peter is a post-bac in Columbia's E3B program. Peter works in breeding wild caught Betta fish, and assists Claire and Madison in their behavioral and genetic work.
Elaine is a student at Columbia College. She is interested in how aggression in Betta splendens manifests on the circuitry level and how aggression circuits differ between males and females.
Joseph is a student at Columbia College in the E3B program. He is interested in the behavioural and evolutionary impacts of climate change as well as understanding complex behavioural processes through the study of genetics.
Yuyang is a Statistics student at GSAS. He is extracting behavioral features and validating models on in Betta fish behavioral patterns.
Yuqi is a student at Columbia Mailman Public Health school. She is interested in developing and validating statistical methods for modelling and analyzing Betta splendens aggressive behavior.
Wenxuan is a Statistics Student at GSAS. He is interested in how statistical models can extract patterns of animal behaviors. He is working on Peromyscus tracking data and modeling of the parental care behavior.
Julio is a dachshund and really good at detecting and retrieving food (that belongs to others).
