Gerkotze Bonthuys (“ Innovative Decision Support in a Petrochemical Production Environment ”) has an MSc degree in chemical engineering. He has been working for Sasol as a process engineer since 2008. He started in the Secunda gas production environment and currently works in the gas and utilities environment focusing on air separation. He has used the gas factory model to study the feasibility of the expansion of production capacity at gasification and the effect of installing additional cooling capacity at gas cooling on production throughput. He enjoys stochastic modeling because he can use his skills as a process engineer and his experience in the gas production environment to analyze and scrutinize the stochastic results and ultimately improve productivity across a larger value chain. Ebert Cawood (“ Innovative Decision Support in a Petrochemical Production Environment ”) is a chemical engineer at Sasol. He was introduced to stochastic modeling while looking for a better way to model a solids-handling batch-operating plant. He worked in the operations research group in 2008 where he built a stochastic model of Sasol's Benfield units. This forms part of the gas factory model. Although no longer part of the operations research group, he still uses a stochastic model, primarily to do stock predictions and to plan statutory shutdowns for the Sasol synfuels catalyst plant. Jay Cunningham (“ Taking the Politics Out of Paving: Achieving Transportation Asset Management Excellence Through OR ”) has worked as a professional engineer in private, university, and public sectors. He is assistant director of maintenance and environment with the New Brunswick Department of Transportation (NBDoT). He has worked in various positions within the NBDoT, including asset management, corridor planning, fleet services, policy development, and highway operations. Jay holds a bachelor's degree in civil engineering and a master's of science degree in transportation engineering from the University of New Brunswick, Canada. Miguel de Lascurain (“ INDEVAL Develops a New Operating and Settlement System Using Operations Research ”) is a professor in the Department of Industrial and Operations Engineering at the Instituto Tecnológico Autónomo de México.

Luis de los Santos (“ INDEVAL Develops a New Operating and Settlement System Using Operations Research ”) is head of the subdivision of securities settlement systems and central counterparties at the Bank of Mexico. He earned a master's degree in finance from the Instituto Tecnológico Autónomo de México and has worked in the Mexican Central Bank's payment system division for 13 years. Esmi Dreyer (“ Innovative Decision Support in a Petrochemical Production Environment ”) is an assistant operations researcher in Sasol's stochastic operations modelling team. This is her first job after completing a BSc (honors) in chemistry with mathematics and applied mathematics in 2008. Her stochastic modeling experiences have included the sizing of various product tanks and upgrading the interface of the gas factory model. She enjoys working in OR because it allows her to illuminate the underlying structure of the world around her while satisfying her need to do something practical, sensible, and useful. Ingrid Farasyn (“ Inventory Optimization at Procter & Gamble: Achieving Real Benefits Through User Adoption of Inventory Tools ”) leads the European branch of the PS Analytics organization of Procter & Gamble. She focuses on supply network design, inventory modeling, and decision analysis. She holds an MSc in engineering from the Catholic University of Leuven, Belgium and the University of Calgary, Canada. She is CPIM and CSCP certified. She has coauthored several papers that have been published in Interfaces and the European Journal of Operational Research. Andrea Feunekes (“ Taking the Politics Out of Paving: Achieving Transportation Asset Management Excellence Through OR ”) is a founding partner and co-CEO of Remsoft. An award-winning entrepreneur, she is responsible for the company's strategic direction and plays a leading role in the day-to-day operations of the business. Under her leadership, Remsoft has grown from a start-up with a handful of key clients in the early 1990s to a leading provider of software and services for sustainable management in use on six continents. Andrea holds a bachelor's degree in outdoor recreation (honors) and a BA in geography from Lakehead University in Thunder Bay, a postgrad diploma in secondary education (geography) from McGill University in Montreal, and a master's of science in forestry from the University of New Brunswick, Canada. Ugo Feunekes (“ Taking the Politics Out of Paving: Achieving Transportation Asset Management Excellence Through OR ”) is cofounder and chief technology officer of Remsoft. He is regarded as the leading developer of software for integrated land management using linear programming technologies. He leads Remsoft's research and development program and overall product development and provides direction for the company's training, service, and maintenance programs. Under his direction, the Remsoft system has become the most widely used software application for resource management in public and private sector organizations around the world. Ugo holds a BS degree in forestry from Lakehead University, a BS in computer science and mathematics from McGill University, and an MS in forestry from the University of New Brunswick, Canada. Marc Fischer (“ Managing Global Brand Investments at DHL ”) holds the Chair of Business Administration with specialization in marketing and services at the University of Passau, Germany. His expertise includes the measurement and management of marketing performance, brand management, and the optimization of the marketing mix. His research appears in journals such as Marketing Science, the Journal of Marketing Research, and Quantitative Marketing and Economics. Michele Fisher (“ Innovative Decision Support in a Petrochemical Production Environment ”) stumbled on a career in OR after completing a BSc (honors) in mathematics at Queen's University in Canada. The subsequent 20 years have exposed her to a range of problems in support of operations at the Department of National Defence in Canada, the North Atlantic Treaty Organization in the Netherlands, peacekeeping operations in Bosnia-Herzegovina and Afghanistan, and now for Sasol in South Africa. She is a generalist with many techniques in her OR toolbox. She loves the challenge of problem definition and the rewards of presenting results that provide immediate and relevant decision support. She is a senior operations researcher in the stochastic operations modeling team at Sasol Technology. Her work is focused on discrete event simulation modeling of energy and steam in the petrochemical production processes and on human resources modeling. Tjark Freundt (“ Managing Global Brand Investments at DHL ”) is a partner at McKinsey & Company, based in Hamburg, Germany.
