Dr. M. Sam Mannan

Dr. M. Sam Mannan is Regents Professor in the Chemical Engineering Department at Texas A&M University and Executive Director of the Mary Kay O’Connor Process Safety Center at the Texas Engineering Experiment Station. The mission of the Center is to improve safety in the chemical process industry by conducting programs and research activities that promote safety as second nature for all plant personnel in their day-to-day activities.  Before joining Texas A&M University, Dr. Mannan was Vice President at RMT, Inc., a nationwide engineering services company.  Dr. Mannan also holds concurrent joint appointments as Professor of Mechanical Engineering, Professor of Petroleum Engineering, Professor of Industrial and Systems Engineering, Professor of Materials Science & Engineering at Texas A&M University.


Dr. Mannan is a registered professional engineer in the states of Texas and Louisiana, a Certified Safety Professional, and a Professional Process Safety Engineer.  His experience is wide ranging, covering process design of chemical plants and refineries, computer simulation of engineering problems, mathematical modeling, process safety, risk assessment, inherently safer design, critical infrastructure vulnerability assessment, aerosol modeling, and reactive and energetic materials assessments.


Dr. Mannan is involved very closely with projects that include hazard assessment and risk analysis, process hazard identification, HAZOP (hazard and operability) studies, vulnerability assessment, process safety management, and risk management.  His research interests include development of inherently safer processes, application of computational fluid dynamics to study the explosive characteristics of flammable gases, development of quantitative methods to determine incompatibility among various chemicals, application of calorimetric methods for the assessment of reactive hazards, and the application of consequence analyses to assess the impact of process plant incidents.  He co-authored the Guidelines for Safe Process Operations and Maintenance published by the Center for Chemical Process Safety, American Institute of Chemical Engineers.  He is the editor of the 3rd and 4th edition of the 3-volume authoritative reference for process safety and loss prevention, Lees’ Loss Prevention in the Process Industries.  Dr. Mannan has published 299 peer-reviewed journal publications, 5 books, 8 book chapters, 220 proceedings papers, 14 major reports, and 272 technical meeting presentations.


Dr. Mannan is the recipient of numerous awards and recognitions including the American Institute of Chemical Engineers Service to Society Award, the Texas A&M University Association of Former Students’ Distinguished Achievement Award for Teaching, the Texas Engineering Experiment Station Research Fellow, the Texas A&M University Dwight Look College of Engineering George Armistead, Jr. ’23 Fellow.  In 2003, Dr. Mannan served as a consultant to Columbia Accident Investigation Board.  In 2006, he was named the inaugural holder of the T. Michael O’Connor Chair I.  In 2007, he was elected Fellow of the American Institute of Chemical Engineers.  In December 2008, the Board of Regents of Texas A&M University System recognized Dr. Mannan’s exemplary contributions to the university, agency, and to the people of Texas in teaching, research and service by naming him Regents Professor of Chemical Engineering.  Dr. Mannan is a Guest Professor at the Nanjing University of Technology and the China University of Petroleum in Qing Dao.  In September 2011, the Technical University of Łódź, Poland, conferred the Doctoris Honoris Causa on Dr. Mannan. In 2012, Dr. Mannan was awarded the Bush Excellence Award for Faculty in Public Service. In March 2013, Dr. Mannan was named a Distinguished Honorary Professor at the Rajiv Gandhi Institute of Petroleum Technology.  In 2015, Dr. Mannan was elected Fellow of the Institution of Chemical Engineers, UK.


Dr. Mannan received his B.S. in chemical engineering from Bangladesh University of Engineering and Technology (BUET) in Dhaka, Bangladesh in 1978, and obtained his M.S. in 1983 and Ph.D. in 1986 in chemical engineering from the University of Oklahoma.
