Dr Emeka Amalu is a Senior Lecturer at Teesside University, Middlesbrough, UK. He is a Chartered Engineer (CEng) and a member of the Institution of Mechanical Engineers (IMechE) as well as the Institution of Engineering and Technology (IET). Emeka achieved the status of Fellow of Higher Education Academy (FHEA). Dr Amalu’s remit is to combine scientific knowledge, mathematics and modelling skills to provide solutions to societal engineering problems. 

Dr Amalu has very relevant teaching, research skills and experience. He has taught a range of mechanical engineering and mathematics modules over his thirteen year academic career. His previous roles included Postdoctoral Research Fellow at the University of Wolverhampton (UoW), UK; part-time lecturer at the University of Greenwich at Medway, UK; as well as Senior Lecturer at the University of Benin, Nigeria. His effective teaching practice earned him a nomination for the Inspirational Lecturer Award 2013/14 and 2015/16 sessions awarded by the UoW Student Union.

Dr Emeka Amalu is research active. His areas of interest include sustainable energy technologies, electronics packaging reliability and systems modelling as well as characterisation of soft solids. He employs experimental mechanics and modelling in his research. His modelling capabilities include 3-D Static Structural, Steady State Thermal and Computational Fluid Dynamics. Utilising Computer Aided Engineering (CAD) coupled with ANSYS Finite Element Analysis (FEA), Emeka models the response of structural systems to applied loads and predicts their performance. He has a PhD completion and currently supervises two PhD students. In addition, he has experience in proposal development and has submitted to EU Horizon 2020 and Royal Society calls.

Dr Amalu is a visiting Research Fellow to Kwame Nkrumah University of Science & Technology, Ghana and collaborates with many academic research groups in the UK, Europe, USA, Asia and Africa. Dr Amalu has over 40 publications in high impact factor journals and has published over nine journal articles and five conference papers during his PhD studies, which earned him the prize for the best PhD Student 2012, awarded by the School of Engineering, UoG, London. His research outputs were included in the UoW Research Excellence Framework (REF) submission under General Engineering in 2014.

Research interests

The areas of my research expertise are in the fields of electronics, soft solids, sustainable energy and systems’ modelling:

(I)Microelectronics
The areas include electronics manufacturing, assembly, reliability and integrity of microelectronic solder joints. In addition, I am also interested in study on the thermo-mechanical reliability of 3-D electronics packaging using components which include flip chip package and package-on-package. I am highly experienced in experimental mechanics and have designed and conducted experiments which required operating a vast array of equipment used in electronics assembly, reliability, testing and damage mechanics. Moreover, I am experienced in the statistical analysis of large data pool.

(II) Materials
I conduct research focused on rheological characterisation of solder pastes to inform on their stencil print performance behaviour. This area of research is stretched to include investigation on thermo-fatigue and durability of solder materials used as solder joints to assemble miniaturised electronic components on the substrate printed circuit board.

(III) Sustainable energy
Recently, I have advanced my research expertise to include photovoltaics technology. I conduct research focused on improving the cell, contact and interconnection technologies of PV modules for improved output power, power conversion efficiency and the interconnection reliability especially for operations in hot temperature climates. This involves optimisation of the design parameters associated with thermal management and structural integrity of the PV module assembly for increased operational reliability. 

(IV) Systems Modelling
I am an expert in static structural and steady state thermal modelling of systems. I am also knowledgeable in the application of ANSYS CFX package to model fluid behaviour. I can confirm that I employ Computer Aided Engineering (CAE) and Finite Element Analysis (FEA) using ANSYS software to model and provide solutions to engineering problems associated with reliability predictions of systems and processes, with specific emphasis on electronics and photovoltaics interconnections, assembly, packaging and manufacture.
