Albert Yumol is an activist who exposes corruption with data science. He teaches Filipinos - literally door knocking at times - about the importance of data privacy. This task is made mildly more difficult by the fact that people in the Phillipines don't really have the concept of 'self'. His mitigation: that privacy is in fact a 'we' thing (not an 'I' thing). As much a fascinating discovery of his homeland archipelago, he emphasises the importance of basic data quality before you can even get to the clever stuff - although he also shares some clever stuff. His enthusiasm is endless.
