Lead author of data-cascades (CHI 2021), the study that named data cascades and put a prevalence figure on them. The paper is published through Google Research, which is the affiliation evidenced by the source.
The relevant thing for this wiki is the method rather than the person: the work is HCI, built on 53 practitioner interviews across India, East and West African countries and the USA, and it establishes a claim about machine learning without training or evaluating a model. That is why this corpus’s ML-side searching kept missing the data layer.
