We are delighted to announce the call for participation in VIZBI 2011, the 2nd workshop on ‘Visualizing Biological Data’, to be held at the Broad Institute, Cambridge-MA (USA), March 16-18, 2011. VIZBI 2011 brings together scientists actively using or developing computational visualization to study a diverse range of biological data. As shown on the attached poster, they have assembled a list of high-profile speakers who will each review the state-of-the-art and challenges with visualization in their field. VIZBI 2011 also features an ‘art & science’ evening (Thursday) during which they will be joined by medical illustrators, graphic designers, and artists interested in biological visualization. On Saturday, March 19, immediately after the workshop, participants can choose from a range of tutorials and take part in a hands-on ‘bring-your-own-data’ session.
