The Under the Influence book is based upon the eponymous symposium, which brought together scholars and practitioners of architecture in order to focus on one of the most anxious disciplinary topics: influence. The symposium invited each of the participants to illuminate a single term -- a disciplinary synonym for appropriation--and through that term, the specific strategies, historical, and disciplinary circumstances in which it is enmeshed. It was organized and hosted by Ana Miljacki, and presented by the MIT Department of Architecture. The book includes introductory texts by Mario Carpo and Nader Tehrani and discussions moderated by Ana Miljacki, Amanda Reeser Lawrence, and Michael Kubo. Participants include Alexander D'Hooghe, Florian Idenburg, Enrique Walker, Michael Meredith, Sam Jacob, Cristina Goberna, Urtzi Grau, Amanda Reeser Lawrence, Ines Weizman, Mariana Ibanez, Simon Kim, Timothy Hyde, John McMorrough, Eric Howeler, and Meejin Yoon.
