The Royal Society of Chemistry (RSC) is scheduling its fourth High Throughput Technologies (HTT4) course for chemists and chemistry users on 20-22 March. The course runs at the University of Cambridge and has a large number of expert practitioner speakers in the field, both academically and industrially based, representing the breadth and rapid growth of current usage of HTT. One of the speakers is GlaxoSmithKline's Martin Owen, who on Day 3 is leading a session on Data and Design of Experiments. PROSIM will feature in a supporting role during Martin's session.
