Though spanning multiple years, pursuing a PhD often feels like a never-ending story—in a good way. It’s the beginning of a lifelong journey, meeting friends from around the globe and finding one’s drive. This is certainly the case for Antony Cyril Arulrajan, who is not only about to earn his degree but has also started his own company.
The people behind the science, and the science behind the people
What motivates a young researcher to travel halfway across the world to work for a few years? It must be a special experience, one that changes lives. Such is the case for nearly-defending PhD candidate Antony Cyril Arulrajan.
“I have always enjoyed meeting people from all over the world, so I was thrilled to be accepted for a PhD at Wetsus,” Antony explains. Though Leeuwarden might not sound like a world city, it bustles with internationals. It’s a hub of cooperation, immediately evident upon arrival. “I specifically chose Wetsus because it is application-focused and collaborates with companies outside of academia,” he adds. The focus on today’s challenges, rather than tomorrow’s, drove the young researcher forward.
Take the looming freshwater shortage. Entire countries already rely on modern technology to convert seawater into drinking water. Yet, conventional techniques require regular maintenance and significant energy. An alternative desalination method, capacitive deionization, shows promise but had problems with pH swings before Antony’s research. His mission was to stabilize the system.
First, they simulated the problem using table salt in clean water, posed a hypothesis, and devised a solution. “That is, until we tried with real waters and encountered a completely different problem. Suddenly, we were dealing with dissolved CO2, which influenced the pH. I was happy to be testing real systems because it led to real solutions—a thicker membrane. If we had stuck to simulating saltwater, we might have done fundamental research in a different direction that wouldn’t have solved this problem,” Antony adds with a smile.
The young researcher discovered that doing a PhD is about deep, careful investigation. Antony felt he could do more, and move even more quickly towards applied solutions. This inspired him to start his own company, validating a new technology in the little time he had while preparing his dissertation.

In wrapping up his Wetsus journey, there are plenty of lasting memories and great takeaways. “I shared an office with nine others; it didn’t stop us from going out together whenever we could. I even co-organized a cycling club at Wetsus, leading to an eleven-city tour. I made great friends, who remain friends to this day. And I’m still invited to meet-ups,” he fondly recalls.
