Bio

Dr. Al Hajaj received his BSc in Mechanical Engineering from the University of Arizona, in 2004. He followed with master’s degrees in Mechanical Engineering from the University of Miami, in 2006 and another in Sustainable Energy Futures from the Imperial College London in 2008. In 2014 Dr. Al Hajaj completed his PhD in Chemical Engineering from the Imperial College London.

Dr. Al Hajaj was part of the Abu Dhabi National Oil Company (ADNOC) as an ADNOC Scholar from 1999 till 2006. He worked as an overhaul engineer at the Abu Dhabi Gas Liquefaction Company in 2006-2007. From 2007 till 2014 Dr. Al Hajaj was a fellow at the Masdar Institute, and from the 2009-2014 period he was also a research assistant at the Imperial College London. In 2015 Dr. Al Hajaj was a visiting professor at the Massachusetts Institute of Technology, following which he joined Masdar Institute as an assistant professor in 2014.

Dr. Al Hajaj completed his teaching certificate program at MIT, where he was inspired by the active teaching techniques and learning experiences of the students. His aim of teaching is to enhance students’ ability to apply and integrate elements of chemical engineering to solve problems of analysis, design, operation, control and optimization in chemical engineering practice. Dr. Al Hajaj looks to enhance students’ ability to develop first-principle mathematical models derived from an understanding of the fundamental process physics and the interaction between physics and mathematical/numerical solution methods. He works on developing innovative programs to encourage post-graduate students to acquire the knowledge, skills, and attitudes necessary to become engineering leaders.

Dr. Al Hajaj’s research lies at the interface of chemical engineering, operations research, computational chemistry and biology. His research focuses in major areas of process systems engineering:  product synthesis and process design; operation and scheduling; optimization; and control. His research goal is to develop systematic tools that help process industries understand the performance of complex systems and solve decision making issues. His underlying approach is based on addressing fundamental problems using multi-scale process systems engineering approach whereby a model of complex system that exhibits behavior across length and time scales which vary over many orders of magnitude is described through a series of interacting, scale specific models.
