The most important series of symposia are the International Symposia on Chemical Reaction Engineering or [http://www.iscre.org/ ISCRE conferences].  These three-day conferences are held every two years, rotating among sites in North America, Europe, and the Asia-Pacific region, on a six-year cycle.  These conferences bring together for three days distinguished international researchers in reaction engineering, prominent industrial practitioners, and new researchers and students of this multifaceted field.  ISCRE symposia are a unique gathering place for reaction engineers where research gains are consolidated and new frontiers explored.  The state of the art of various sub-disciplines of reaction engineering is reviewed in a timely manner, and new research initiatives are discussed.
