Research Interests

My research interest lies in Engineering and Materials Sciences focusing on the understanding of defects in materials and developing processes for photovoltaic applications. My research work in a photovoltaic industry (2010 to 2013) focused on optimising and/or developing a new process for photovoltaic cells and modules. My current research focuses on improving solar cell efficiency through improving materials, characterisation of materials and developing processes.


I joined WMG in 2017 as a Senior Teaching Fellow in the field of Mechanical Engineering. I was previously an Engineering Tutor at the Coventry University. I hold a Fellow of the Higher Education Academy (FHEA)

I completed a first-class BSc. in Mechanical Engineering from Bangladesh University of Engineering and Technology (the top-ranked engineering university in Bangladesh), in 2005. I studied all the major subject areas in Mechanical Engineering. In 2009, I completed an MSc. in Sustainable Energy Technologies at the University of Southampton, UK with Distinction. The key modules studied are Automotive Propulsion, Energy Resources and Engineering, Sustainable Energy Systems and Renewable Energy. After several years of working in an industry, I received a Departmental scholarship in the School of Engineering at Warwick in 2013 to pursue a PhD degree in silicon materials for photovoltaic applications and passed in 2017.

I am the author of several publications which were published in leading journals in my research field including Journal of Applied Physics and IEEE Journal of Photovoltaics. My research works have been presented in international conferences including Gettering and Defect Engineering in Semiconductor Technology, Germany (GADEST' 2015), 43rd IEEE Photovoltaic Specialists Conference, USA (IEEE PVSC 2016) and 7th International Conference on Crystalline Silicon Photovoltaics (SiliconPV 2017). My research works have also been presented at the E-MRS 2016 spring meeting and accepted for GADEST 2017 conference in Georgia. I worked as a 'chair' of a session in the International Conference on Renewable Energy: Generation and Applications (ICREGA 2012) in the University of UAE.
