INTRUCTOR BIOS

Mark Badowski, Programme Manager "Furnace Metallurgy and Melt Treatment" of Hydro Aluminium graduated in 1999 in Metallurgy with the specialization in metal forming and received his PhD from the University of Technology in Aachen in 2005 for his work on vertical strip casting of steel. He is currently employed at the Hydro research centre Bonn, Germany and has worked there for more than ten years on melt treatment issues in the cast houses including melt quality measurement systems.

Bill Betts is a lead metallurgical engineer at the Solatens Technology Center of Novelis in Spokane, USA. He holds a BS in Metallurgical and Materials Engineering from Cal Poly, San Luis Obispo. His 18 years in the aluminum industry have been focused on process and product development of beverage can sheet, continuous strip casting, and DC casting. His current work is focused on the development of Novelis’ advanced DC casting technologies including Fusion (multi-alloy DC ingot casting) and Flextreme (continuous horizontal billet casting).

Dr. Don Doutre completed his PhD in Metallurgical Engineering at McGill University in 1984. His thesis topic was "The Development of a Rapid Method for the Determination of Metal Cleanliness" which is now known as the LiMCA technology. After joining Alcan’s research Laboratories he was actively involved in the further development of measurement techniques (AlScanTM/PoDFA) and molten metal treatment (Rotary Gas/Flux Injection). He has also been active in the area of metal matrix composites (BoralcanTM), semi-solid forming (SEED process) and foundry/shape casting. He is currently with Novelis’ Molten Metal Processing group and involved in all aspects of aluminum recycling.

Henrik Gripenberg is a senior expert for nonferrous applications at Linde Gas Headquarters. He has also worked for Jernkontoret, Sandvik AB, and AGA AB during his career. He received his M.S. in metallurgy from the Royal Institute of Technology, KTH, Stockholm in 1977. Gripenberg has published several conference and journal papers and patents in the fields of aluminum recycling, heating, and melting.

Anders Johansson works as Senior Advisor in Gränges Sweden AB, mainly with process development, investments, environment, and research. He has a master of science in metallurgy from the Royal Institute of Technology 1989 in Stockholm Sweden. He has a background in casting, rolling, and extrusion of aluminium. Anders has made several publications regarding energy and metallurgy together with companies e.g. ABB, LINDE, SINTEF, and DEMIDOV.

Anne Kvithyld is a senior research scientist at SINTEF, Norway, where she has been since 2007. Her research interests are centered around refining and recycling of metals. She earned her PhD entitled "Thermal decoating of aluminium scrap" in 2003. She has been a Visiting Post.Doc Colorado School of Mines, USA and was the winner of the 2011 Vittorio de Nora Award for Environmental Improvements in Metallurgical Industries.

Gary Parker received his B.S in Metallurgical Engineering from the University of Alabama in 1985 and is currently the Casting and Reclamation Process Manager for Wise Alloys. Gary has over 25 years’ experience in the aluminum industry working for Wise Metals and previously for Reynolds Metals Company. During his career he has worked in various Metallurgical Engineering Roles involving Molten Metal Quality, Casting R&D, EM and DC casting and General Casting Process Improvement. His roles have included Process Engineer, Product Engineer, Research Engineer, Section Supervisor, Process Improvement Team Leader and Casting and Reclamation Process Engineering Supervisor. He has prepared and presented numerous training classes for plant personnel and customers. He holds two U. S. Patents involving Process Improvements for Aluminum.

Ray D. Peterson is Technology Director for The Recycling Divison of Aleris International. He has also worked for IMCO Recycling and Reynolds Metals Company during his career. Ray received his Ph.D. in Metallurgy from the University of Utah in 1984. He has served in many areas of the TMS volunteer organization including Chair of the TMS Aluminum Committee, Light Metals Division Chair, and President of the Society. His professional research interests include molten salt reactions, high temperature thermochemistry, reaction kinetics, heat and energy transport, and molten metal processing.

Lawrence Ray Ray is the Molten Metal Treatment Technology Manager within Alcoa’s Casthouse Center of Excellence. During his career at Reynolds Metals Company and Alcoa, he has held R&D and technical roles supporting casting process development, metal treatment and analysis, and development of packaging materials. Lawrence received his M.S. in Materials Engineering from North Carolina State University in 1984.

Peter Schumacher obtained his Diplom Ingenieur in Mechanical Engineering at the University of Braunschweig (Germany) and a PhD at the Department of Metallurgy and Materials Science at the University of Cambridge (U.K.). Since 2002 Peter is managing director of the Austrian Foundry Research Institute (ÖGI) and holds the Chair of Casting Research at the Montanuniversität Leoben, Austria. Peter has 25 years experience in light metals research and technology in continuous and shape casting (Alcan, LSM, ÖGI) with a particular focus on grain refinement. He has been actively involved in issues of the shape casting plants of major European automotive OEMs and their suppliers. His current scientific focus is also on the control of trace elements regarding the modification of eutectic structures and the phase selection of intermetallics in light alloys.

His work on grain refinement of aluminium and magnesium has been awarded internationally and he is regularly invited to give invited talks at international conference on casting technology issues. Peter also organises teaching courses for foundry men to transfer gained knowledge right down to the shop floor.

Peter has three patents, published two book chapters and more than 80 conference and journal papers.
