Coastal Passions, Global Impact: A Research Journey
When your passion becomes your profession, the result can be both inspiring and impactful. For Hao Wang, a young researcher at Deltares—an independent research institute for applied research in the field of water and subsurface, working worldwide and guided by major societal issues for which its knowledge is indispensable—and a partner in the BlueAdapt project, this has been exactly the case. Growing up with a love for water activities and coastal life, he has turned his personal connection with the sea into a career dedicated to protecting public health and adapting to climate change.
“I’ve always enjoyed being in and around water – swimming, spending time along the coast – so I wanted to combine that personal passion with something meaningful for society. That’s how I became interested in water quality and public health.”
A Journey Across Borders
Hao, originally from China, earned his Master’s degree there, where he studied large catchments and how nutrients from inland waters affect the coast. His passion for water research then brought him to the Netherlands, where he completed a research at Utrecht University. During the research, he discovered the power of numerical models to better understand water pollution.
“I realised that models can save a lot of manual work and provide practical results. When I first used the Delft3D model, developed by Deltares, I was very impressed. I wanted to go beyond using it – I wanted to improve and develop it myself.”
This drive eventually brought him to Deltares, where he joined the BlueAdapt project.
Turning Research into Action
Within BlueAdapt, Hao takes a leading role in Work Packages 4 and 5. He heads a case study in the Netherlands, translating microbiological data into equations that feed into predictive models. These models could help local authorities monitor risks and issue timely warnings for coastal areas.
“We use models to replicate the hidden processes between climate change and pathogens. This lets us test different scenarios, measure the impact of various factors, and design targeted solutions to protect public health.”
Making Complex Science Accessible
We asked Hao how he would explain his research to a child, he smiled and said:
“Imagine the sea is like a swimming pool, and sometimes invisible germs get into the water. Climate change—like heavy rain, floods and floods—can make it easier for those germs to spread. I built a ‘virtual swimming pool’ on the computer to test what happens, so we can know when the water might not be safe and how to keep people healthy.”
With this simple “virtual swimming pool” example, Hao proves that even complex science can be explained in a way that children can understand.
Building Connections and Sharing Discoveries
Even as an early career researcher, Hao has already participated at major international conferences, including EGU and WaterMicro25. These events were more than just presentations – they were transformative experiences.
“Conferences are incredibly important because they help you build a network. Before my talks, I was usually the one approaching people to start conversations. After presenting, researchers came to me with questions and ideas for collaboration. That was very rewarding.” he recalls.
At EGU, he introduced an improved model of faecal indicator bacteria, incorporating new processes like sediment interaction and sunlight effects – making it more accurate and flexible than previous models. At WaterMicro25, he showcased a prototype model that tracks bacteria from their very source through urban systems into coastal waters. The ultimate goal was to eventually link this with weather forecasts to predict bacterial risks days in advance.
Challenges, Opportunities, and Fun Moments
Being part of BlueAdapt has also given him the chance to work across disciplines and cultures: “The project is very interdisciplinary – microbiologists, modellers, economists, policy experts. I’ve learned how research can move from fundamental science all the way to societal impact, and I’ve gained new perspectives by working with colleagues from many different backgrounds.”
Of course, conferences are not only about science. He recalls with a laugh: “At WaterMicro25, I co-chaired a session for the first time – a big learning experience. And at the conference dinner, professors who are usually very serious suddenly became very lively and engaging. It was unforgettable.”
Inspiring the future
When I asked him about his motivation, Hao didn’t hesitate to answer:
“I want to use the technology we have to make life easier for both policymakers and the public. Automatic tools can help local authorities know when and where to monitor, without extra work, and at the same time protect people’s health. That’s what drives me.”
For young researchers considering a similar path, his advice is simple but powerful:
- Explore broadly. Try different approaches until you find what excites you most.
- Use the resources. Take advantage of the innovative tools, software, and data available in your environment.
- Stay open and resilient. Research is full of challenges, but by sharing your work and engaging with the community, you’ll find your place.
Through his journey, Hao represents the spirit of BlueAdapt; combining science, passion, and collaboration to tackle one of the most pressing challenges of our time—protecting health in a changing climate.
His story is not only about innovative models and international projects, but also about how personal passion can inspire professional impact.
