My name is Akiko Kumada, and I currently direct the High Voltage Laboratory at the University of Tokyo. I completed my doctoral studies there in 1999, focusing on the development of a surface discharge measurement system using a Pockels sensor—an experience that shaped my enduring interest in gas discharges and optical diagnostics. After a brief period at Tokyo Electric Power Company, I returned to academia and continued my research in high voltage insulation.
In my 30s, I was largely occupied with raising children, which made long-term overseas research difficult—a situation that might be easier today. In the 2010s, I began turning my research focus toward insulation under repetitive surge conditions, which were becoming increasingly important with the spread of power electronics. Around 2011, I started studying both partial discharge phenomena in gel materials and insulation issues at the end turns of motor windings. Through the latter, I had the opportunity to work with Dr. Steve Boggs, who was deeply involved in this area.
He encouraged me to submit to DEIS conferences such as ICD and EIC and introduced me to a broader international research community. Although I haven’t conducted long-term research abroad, I’ve come to realize that meaningful collaboration can still happen—with the right connections and a bit of persistence.
I vividly remember submitting my first paper to ICDL, based on my understanding that cavities caused by partial discharges in gels would self-heal due to their viscoelastic nature—similar to liquids. I assumed this idea would resonate with the liquid discharge community, but I quickly realized that “liquid discharge” typically refers to behavior in convective fluids, not fast-response quasi-solids. That experience reminded me how easy it is to misread disciplinary boundaries—and how valuable those stumbles can be.
DEIS has provided a platform to grow both technically and as part of a global community.
Through conferences, workshops, and committee work, I’ve been able to connect with researchers worldwide and contribute to projects that transcend disciplines and borders.
Serving on the AdCom and now as Vice President has deepened my appreciation for the Society’s commitment to diversity, mentorship, and collaboration.
To young professionals and students: technical skills matter, but so do networks and conversations. Don’t be afraid to reach out, ask questions, or make mistakes, especially when stepping into new territory. What feels like a detour may lead you exactly where you’re meant to go.
