This research considers how industrial and business service firms interact and develop value propositions and sales strategies in often highly complex networks, and analyses how moves by specific players in a given market shapes those of others. Prof Geiger is the author of many academic articles in top international journals in this area and has co-authored two books: ‘Sales Management: A Multinational Perspective’ (2011, Palgrave Macmillan) and ‘Concerned Markets’ (2014, Edward Elgar). She has recently won a EU Marie Sklodowska Curie Fellowship for a research project on Silicon Valley’s health technology ecosystem, in association with the University of California Berkeley’s CITRIS technology centre, where she will be based in 2015/16.
