The incentive circuit of the fruit fly brain: a computational perspective
In this poster we show how our anatomically accurate incentive circuit predicts the responses of mushroom body neurons from the fruit fly brain and how they can be used to create similar behaviour to the one observed in the animals.

How flies acquire, forget and assimilate memories: a computational perspective
In this talk we present our recent work building an anatomically accurate neural circuit that allow memory dynamics in the fruit-fly brain.

From skylight input to behavioural output: a computational model of the insect polarised light compass
We propose a new hypothesis for how insects process polarised skylight to extract global orientation information that can be used for accurate path integration. Our model solves the problem of solar-antisolar meridian ambiguity by using a biologically constrained sensor array, and includes methods to deal with tilt and time, providing a complete insect celestial compass output. We analyse the performance of the model using a realistic sky simulation and various forms of disturbances, and compare the results to both engineering approaches and biological data.

Insect neuroethology of reinforcement learning
Thesis - Doctor of Philosophy. I inversigated how insects form associative memories in their mushroom bodies and how this impacts their olfactory learning, visual navigation, and time-delayed reinforcements tasks.
Miniature insect model for active learning (minimal)
We develop a new foundation for understanding natural learning by developing a complete multilevel model of learning in larvae
