Dr. Andrew Chew; Vacuum (AM) Session
Dr Andrew Chew received his PhD in Vacuum Metrology from University of York, UK in 1993. He has worked within the vacuum industry for over 20 years and currently holds the position of Global Applications Manager at Edwards Vacuum. He specializes in vacuum system design and analysis for large HEP R&D projects and general industrial applications. He maintains an interest in the dynamics of molecule-surface collisions and momentum transfer.

Dr. Anthony Taylor; Semiconductor Applications (PM) Session
Dr Anthony Taylor received his PhD in Physics from Rensselaer Polytechnic Institute in 1993. He has worked within the vacuum industry for 19 years and currently holds the position of Applications Engineer at Edwards Vacuum. He specializes in vacuum systems used in the semiconductor industry and how the process by-products interact with the systems.
