overview

Professor Chen’s research group performs interdisciplinary research in optics science and photonic engineering.

We develop innovative laser technology for advanced manufacturing and clean energy production; distributed optical sensors for energy and robotics applications; photonic integrated circuits for compact optical system developments; distributed sensor enabled artificial intelligence data analytics and digital twins; and sensor fused additive manufacturing.

Our research group is superiorly equipped with both world-class research equipment and highly capable innovators. This powerful combination enables us to produce high-impact scientific knowledge, highly valuable intellectual properties, mission-critical product prototypes, and important technology know-how for our national lab and industry partners.

Unlike a "conventional" optics group, our research team includes highly trained researchers with diverse technical backgrounds in laser, fiber optics, material sciences, renewable energy, electronics and FPGA, mechatronics, radar and imaging processing, and machine learning. This diversity keeps us open-minded and drives interdisciplinary innovations. As a collaboration friendly and inclusive research team, Professor Chen works with 14 highly motivated researchers including 5 female PhD and PDF researchers. Our group is well-known in industry for strong capabilities in reel-to-reel fabrication of distributed fiber sensors and in the development turn-key fiber sensor interrogation instruments for advanced energy systems..
