Fabrice Abunde is a final year doctoral fellow and research assistant at Institute for Marine Operations and Civil Engineering, Norwegian University of Science and Technology (NTNU). He is currently conducting his doctoral research at the Brew-Hammond Energy Center of Kwame Nkrumah University of Science and Technology, Ghana.

He holds a Master of Engineering (M.Eng.) in Industrial Chemistry and Environments, a Master of Philosophy (M.Phil.) in Biosystems Engineering and a B.Sc. in Biochemistry and Medical Laboratory Technology.

He is a software developer and sustainable systems engineer with a strong focus in the use of computational techniques for mathematical modelling and simulation as well as synthesis and optimization of engineering systems. His work with the UPERCRET project specifically comprise the development of an integrated model-based framework, which integrates elements of geometry, gradient-based optimization & stochastic simulation for optimal synthesis of methane bioreactor structures, considering both process and economic design objectives.
