CSAIL PI Manolis Kellis helped organize the 4th Annual RECOMB Satellite on Regulatory Genomics, organized jointly by the Broad Institute, CSAIL, and Harvard Medical School. The conference was held at MIT this past weekend and was a tremendous success, with 230 people attending from 10 countries in 4 continents. The scientific program represented the top labs in gene regulation from around the world. Computational and experimental scientists in the area of regulatory genomics discussed current research directions and latest findings and established new collaborations towards a systems-level understanding of gene regulation. The 9 keynotes, 27 talks and 53 posters covered an impressive breadth of subjects in gene regulation, including regulatory network modeling, motif discovery and evolution, RNA-mediated regulation, development and cell state specification, personal genomics, systems biology, and synthetic biology.
