Terrence L. "Terry" Blevins has been actively involved in the application and design of process control systems throughout his career. Terry was instrumental in the initial establishment of Emerson Process Management s Advanced Control Program in 1992. From 1998 2005 Terry was the team lead for the development of DeltaV advanced control products. From 1994 2013 he was the Fieldbus Foundation team lead for the development and maintenance of the Function Block Specification and editor of the SIS Architecture and Model Specifications. Terry is the U.S. expert to the IEC SC65E WG7 function block committee that is responsible for the IEC 61804 function block standards. He is a voting member and chairman of the ISA SP104-EDDL (Electronic Device Description Language) committee and is the technical advisor to the United States Technical Advisory Group (USTAG) for the IEC65E subcommittee. He is also a member of the U.S. National Committee (USNC) Technical Advisory Group (TAG) (IEC/SC65 and IEC/TC65). Terry coauthored the ISA bestselling books Advanced Control Unleashed (2002), Control Loop Foundation (2010) and Advanced Control Foundation (2012). He has over 50 patents and has written over 80 papers on process control system design and applications. Terry received a Bachelor of Science in Electrical Engineering from the University of Louisville in 1971 and a Master of Science in Electrical Engineering from Purdue University in 1973. In 2004, he was inducted into Control Magazine's Process Automation Hall of Fame. Terry is an ISA Fellow. At present, Terry is a principal technologist in the applied research team at Emerson Process Management.
Deji Chen recently joined Tongji University as a professor at the Computer Science Department. His research will be focused on Industrial Internet, which is the continuation of his work at Emerson Process Management where he was a member of the DeltaV future architecture team. Deji has been involved in process automation for almost two decades. He was among the first creators of OPC. He has worked on different fieldbuses including Foundation Fieldbus. He coauthored the first definitive book on WirelessHART, WirelessHART: Real-Time Mesh Network for Industrial Automation (2010) and translated the ISA bestselling book Control Loop Foundation - Batch and Continuous Processes into Chinese (2012). In 1999 he received his Ph.D. from the University of Texas at Austin; his thesis was "Real-Time Data Management in the Distributed Environment." Deji is an IEEE senior member and an ISA senior member.
Mark Nixon has been involved in the process industries throughout his career. Mark started his career as a systems engineer working on projects in oil & gas, chemicals and pulp & paper. He moved from Canada to Austin, Texas in 1988, where he has held positions in both research and development. From 1995 through 2005 Mark was lead architect for DeltaV. In 2006 he joined the wireless team, taking an active role in the development of WirelessHART and IEC 62591. Mark's current research includes control, data analytics, wireless, low power, virtualization and operator interfaces. He coauthored WirelessHART: RealTime Mesh Network for Industrial Automation (2010), Control Loop Foundation - Batch and Continuous Processes (2010) and Advanced Control Foundation (2012). He holds more than 85 patents. In 2012 he was inducted into Control Magazine's Process Automation Hall of Fame. Mark is an ISA Fellow. Mark received his Bachelor of Science in Electrical Engineering from the University of Waterloo in 1982. At present, Mark is the director of applied research at Emerson Process Management.
Willy Wojsznis has been involved in the development of advanced control products over the last nearly 25 years, focusing on model predictive control, auto tuning and data analytics. Over the previous 25 years of his career he worked on developing computer control systems and applications. His professional work has resulted in a number of successful and innovative advanced control products, over 40 patents and over 50 technical papers. He received a control engineering degree (EE) from Kiev Technical University in 1964, a Master of Science in Applied Mathematics from Wroclaw University in 1972 and a Ph.D. from Warsaw University of Technology in 1973. He coauthored the ISA bestselling books Advanced Control Unleashed (2002) and Advanced Control Foundation (2012). In 2010, he was inducted into Control Magazine's Process Automation Hall of Fame. Willy is an ISA Fellow and an IEEE senior member. At present, he is a member of the Emerson Process Management applied research team supporting research into optimization, big data and process data analytics.
