The Kvitsiani group investigates the genetic and neuronal circuit mechanisms that underlie effort based decision-making in flies, rodents and humans. The aim of his research is to build predictive and quantitative models of foraging behavior to uncover the neural and genetic mechanisms that underlie animal decisions. The methods used include molecular genetics, psychophysics, behavioral electrophysiology and optogenetics.
The main focus of our research is to investigate how animals allocate effort to forage efficiently in unpredictable environments. By employing quantitative foraging models and carefully designed behavioral assays with extracellular electrophysiology and optogenetics we plan to identify circuit level computations in mouse brain that subserve foraging decisions. In order to uncover the molecular basis of foraging decisions reverse genetic screens in combination with foraging behavioral assays will be used in fruit flies. Another focus of research will be to determine whether foraging humans use the same strategies as flies and rodents, and whether these strategies are adversely affected in mentally disabled patients. Long term goal is to use ecology inspired quantitative behavioral models to guide and sharpen scientific questions. Duda Kvitsiani also hopes to take advantage of the diverse scientific cultures at Aarhus University to launch fruitful collaborations in pursuit of this goal.
The Kvitsiani group currently has projects available for Master students, PhD students, and post docs. Please contact Group Leader Duda Kvitsiani directly, if interested.

Anna Barta will work on fruit fly project in Duda Kvitsiani’s lab. Anna will test how fruit flies forage for probabilistic rewards under different metabolic states. For this Anna will use newly developed natural reward delivery system in combination with measurements of metabolic state in individual animals. Anna’s work will be a collaboration…

Jesper Hagelskjær will be involved in further developing real-time spike sorting tool that he established during his Ph.D. time. This tool provides instantaneous neural feedback to animals based on the spiking activity of individual neurons and makes it possible to test many of the existing hypothesis in neuroscience. One such hypothesis that…

Initially Dovile Saulenaite will be part of a research project that aims to extend and characterize single fly decisions in probabilistic environments. Later Dovile will be focusing on aspects and possible sources of individuality in fruit fly foraging behavior. She will record foraging decisions of fruit flies for several days, to investigate how…
