Current employment and workplace

Postdoctoral Researcher

How did I become interested in my field of research?

I have always been fascinated by how complex electrical insulation systems behave under stress, and my interest in electrical insulation science began during my undergraduate studies in electrical engineering. When I started working on my master's thesis, I began to explore the aging and degradation of insulation materials to understand the fundamental physics and address real-world challenges, such as the impact of harsh operational conditions. This motivated me to pursue a PhD focusing on the dielectric dynamics and modelling of high-voltage insulation systems, as I could see the importance of this research in advanced applications like renewable energy systems and electrified transportation. The more I dove into the subject, the more I was captivated by the potential to improve energy system reliability and enhance sustainability.

What am I most passionate about in my work?

What excites me most about my work is the ability to bridge the gap between fundamental science and real-world applications. I am particularly passionate about exploring how insulation materials behave under extreme conditions, like high voltage, temperature, and frequency, and understanding the underlying physical mechanisms. What fuels this passion is knowing that my research can directly contribute to making electrical systems more reliable, efficient, and sustainable, with tangible impacts on global energy systems.

In the long term, what impact can my research have on society?

My research has the potential to significantly impact society by improving the reliability and efficiency of electrical systems, which are the backbone of modern infrastructure. As we continue to move toward renewable energy systems, electric vehicles, and smarter grids, the need for high-performance electrical insulation becomes crucial. My work aims to develop more resilient and durable insulation systems that can withstand extreme conditions, such as high voltages and temperatures, which will help enhance the safety and longevity of power systems. Ultimately, this can lead to more sustainable, cost-effective energy solutions and contribute to reducing the environmental footprint of electrical networks.?

What made the strongest impression on you during my PhD defense?

The strongest impression during my PhD defense was the sense of culmination and validation of years of hard work. Preparing for the defense made me reflect on the journey I¡¯ve taken and how my research has evolved. The most impactful moment came when I engaged in a thought-provoking discussion with the committee members. They asked insightful questions that not only challenged me but also deepened my understanding of my work. Their constructive feedback made me realize how much my research has contributed to the field, and how it could be applied to future developments in electrical insulation systems. It was rewarding to have my work recognized by experts in the field and to know that my research could potentially make a meaningful impact on both academia and industry.

What piece of advice would you offer current PhD fellows who want a career outside academia?

Start building a diverse skill set early on and stay open to various career paths. The ability to communicate your findings, collaborate across disciplines, and understand the broader societal and industrial implications of your work can set you apart.

A little bit about the person behind the researcher?

Behind the researcher, I am someone who deeply values continuous learning and personal growth. Originally from China, I have always been curious about how things work, which led me to electrical engineering. Outside of research, I love fitness and exploring nature ¨C it is my way of disconnecting and finding inspiration.?
