_______________________________
I'm research software engineer in the Drosophila Connectomics Group at the University of Cambridge. I'm interested in neuroscience and machine-learning, particularly decision making (of humans, flies and machines). In 2021 I became a Software Sustainability Institute Fellow. Among the others, I worked in the past on brain computer-interfaces, psychophysics, brain connectivity, natural language processing, Shiny packages and neural networks.
I'm also advocate of the open science movement and enjoy contributing to open source tools.
Here you can find how to contact me.
