She is Vice President of Product Design at Wikipedia, where she has recently been exploring methods for quantifying and visualizing the "knowledge gaps" between different language versions of Wikipedia; and ways of quantifying and communicating "trustworthiness" of content on Wikipedia. In prior work, Margeigh led╩a multi-year program at Microsoft to understand and codify etiquette in different╩cultural contexts in order to create algorithms that behave in accordance with acceptable social norms (with regard to what kind and how much private information they ask for in order to perform some task for the user). An Architect by training, Margeigh is drawn to complex, first-of-category design problems that have required immersive research in social behavior and human perception.╩
