Biography
I am an Associate Professor in Power Electronics within the Department of Electrical and Electronic Engineering at the University of Nottingham, where I also serve as Director of Industrial Strategy and Engagement.
My research investigates the key technologies underpinning the next generation of electric vehicles, more-electric aircraft, and renewable energy systems. I focus on high-frequency, high-power-density power converters and advanced semiconductor packaging, addressing efficiency, reliability, and system-level integration.
Within these areas, my interests include:
-
Integrated power conversion for electric vehicle and aerospace applications
-
High power density converters for low-carbon transport and energy systems
-
Wide bandgap semiconductor devices (SiC and GaN) and advanced packaging
-
New DC-DC converter topologies, resonant converters, and soft-switching techniques
-
Digital-twin design methods, converter reliability and health monitoring
-
Inductive power transfer and high-speed drives
-
Advanced thermal management and circularity/recyclability of power modules
Since joining Nottingham in 2020, I have led and contributed to research projects funded by UKRI, Innovate UK, Horizon Europe, and industry partners. These projects span applications in electric vehicle charging, subsea systems, active magnetic bearings, aerospace high-voltage DC systems, and railway traction. I work closely with a range of industrial collaborators across the automotive, aerospace, and semiconductor sectors, building strong pathways for translation of research into practice.
I supervise a growing team of PhD students, postdoctoral researchers, and visiting scholars, and actively mentor early-career academics. My group works closely with industry through collaborative R&D projects, KTPs, and studentships.
Prior to joining the University of Nottingham, I spent 2.5 years as a Senior Design Engineer in automotive power electronics at Dynex Semiconductor, leading the development of on-board chargers and DC-DC converters for electric vehicles. I also contributed to the Emerson Control Techniques Multilevel Drive Research Project as a Research Assistant at Cardiff University.
I hold a PhD (2017) and MSc with Distinction (2013) in Power Electronics, Machines and Drives from the University of Manchester, and a BSc (2011) from the Bangladesh University of Engineering and Technology (BUET).
Expertise Summary
I specialise in designing and delivering next-generation power converters that enable cleaner transport and energy systems. My expertise spans SiC and GaN device integration, advanced packaging, and thermal management, alongside the development of high-efficiency DC-DC and motor drive solutions for electric vehicles, aerospace, rail and renewable energy applications. I work closely with industrial partners to translate cutting-edge research into practical, reliable technologies that support product innovation and market impact.

Current Research
I lead projects that push the state-of-the-art in power conversion technologies, especially where high frequency, high power density, and wide-bandgap semiconductors can make a difference. Key themes include:
-
Design and optimisation of converters for next-generation electric vehicles and more-electric aircraft, integrating power electronics and system validation.
-
Reliability, thermal management, and packaging innovations for SiC and GaN devices to improve durability, efficiency and manufacturability.
-
Novel DC-DC and resonant converter topologies with emphasis on efficiency under variable loads and soft-switching techniques.
-
Battery health and lifetime modelling, along with converter control strategies, to support system reliability.
-
Wireless/inductive power transfer and high-speed motor drives for emerging transport and mobility applications.
-
Exploration of HVDC systems and renewable energy integration, including converter designs for grid interfacing and energy storage.
I am keen to work with industrial partners and external agencies to translate research into products-especially in automotive, aerospace and sustainable energy sectors.
I also welcome enquiries from Home, EU and international PhD candidates interested in contributing to these areas. If you are excited by any of these topics, please email me directly with your CV and a brief summary of your interests.
