Panayiotis Smeros

Hey there! Welcome to this corner of the internet where you can find a bit about me and my work.

I specialize in developing systems with societal impact within collaborative and interdisciplinary environments. I have thirteen years of experience as a research scientist in data analysis, natural language processing, machine learning, and semantic web, with applications in bioinformatics and computational subfields of sociology, journalism, and environmental science.
