Piotr is a data scientist with a quantum physics background. His doctoral thesis was centered on data visualization and complex networks techniques for quantum states. After performing research at MIT in Cambridge, MA; ICFO in Barcelona and ISI Foundation in Turin and authoring 12 publications he switched to working in data science in Warsaw and San Francisco, seeing enormous opportunity in this rapidly growing field. His tools of choice are Python and R for data analysis and Machine Learning and D3.js for interactive data visualizations. He benefits from his research‑level skill in social networks analysis and hierarchical clustering. His talks and expertise were welcomed at Barcelona Python Meetup, Bay Area D3.js User Group and Caltech. He volunteered tutoring gifted schoolchildren of the Polish Children’s Fund, yielding top prizes in the European Union’s Contest for Young Scientists.
