Professor Malte Ziewitz studies the politics and practicalities of evaluation, governance, and accountability in digitally networked environments -- the dynamics at work, the values at stake, the design options at hand. His recent work explores evaluative practice in healthcare and search engine optimization (SEO); algorithmic ordering; the history and performativity of internet governance; and computational approaches to privacy. As Principal Investigator, he headed the ESRC-funded "How's My Feedback?" project, a collaborative design experiment to rethink and evaluate online review and rating websites.
