Tongyao Wu grew up in Fuzhou, China, a coastal city nestled amid mountains and rivers. The natural world developed in beauty all around him, sparking his curiosity about everything under Fuzhou’s warm sun.
“I was naturally curious and enjoyed understanding how things worked,” said Wu, now a graduate researcher with the University of Florida’s Department of Electrical & Computer Engineering, known as ECE. “Growing up, I aspired to become a physicist, as I was fascinated by building experiments, exploring fundamental principles and understanding complex systems behind everyday phenomena.”
As he grew older, his curiosity merged with his thirst for solving problems.
“Engineering appealed to me because it bridges fundamental theory and real-world impact,” he said. “I enjoy translating abstract ideas from physics and mathematics into tangible devices and systems that can address practical challenges. This combination of analytical depth and real-world relevance strongly motivated me to pursue engineering.”
His journey ultimately brought him to UF, where he is a Ph.D. student working with integrated photonics and emerging optical devices with ECE Assistant Professor Elham Heidari, Ph.D. Wu chose UF’s Herbert Wertheim’s College of Engineering for its strong programs, research culture and collaborative academic environment.
“I was particularly drawn to the work of my advisor, Dr. Elham Heidari. UF offered an ideal environment where rigorous training and hands-on research naturally intersect,” he said.
And Heidari is thrilled to have him.
“Tongyao is an exceptional student with a strong physics instinct and a natural ability to figure things out quickly,” Heidari said. “He is a huge asset to the lab — dependable, self-driven and the kind of person who makes everyone’s work easier while quietly pushing projects forward.”
Here, Wu discusses his life in Gainesville and the research that anchors him.
What is your major and area of research?
My research focuses on integrated photonics, with an emphasis on reconfigurable photonic devices and systems for advanced computing, communication and sensing applications.
How will your research translate to real-world issues?
My research investigates how micron-scale optical devices can perform computation, signal processing and information transfer more efficiently than conventional electronic technologies. I work on manipulating light through carefully engineered photonic structures in the classical regime, as well as detecting and controlling photons in the quantum regime.
By harnessing light in these complementary ways, my work aims to overcome fundamental limitations of electronics, such as energy consumption and bandwidth bottlenecks. These photonic approaches have a strong potential for real-world applications, including artificial intelligence hardware, high-speed data communication and next-generation sensing systems, where improvements in energy efficiency, speed and scalability are increasingly essential.
What interested you in this research?
It brings together fundamental physics, device-level engineering and system-level design around a uniquely fascinating object: light.
Light has always intrigued me because of its rich physical properties and its ability to carry and process information in ways that electrons cannot. The opportunity to work with photons across theory, simulation and experimental concepts — and see these ideas evolve into practical, impactful technologies — has been especially motivating and rewarding.
Tell us about your family.
I come from a supportive family that has always valued education and independent thinking. Both of my parents work at universities, which allowed me early exposure to academic environments and research settings. Their encouragement has played an important role in shaping my academic path.
What pop culture are you consuming lately?
Recently, I have been enjoying scientific novels, particularly works that combine strong storytelling with thoughtful exploration of scientific and philosophical ideas.
What do you like to do outside of the lab?
I enjoy hiking and listening to music. These activities help me maintain balance and often provide fresh perspectives that I bring back into my academic work.
