MIT Technology Review has named Lawrence Livermore National Laboratory (LLNL) research scientist Xiaoxing Xia as one of its 2025 Innovators Under 35 — a global list honoring early-career researchers and entrepreneurs who are shaping the future of science and technology.
The publication recognized Xia in the Inventors category for his groundbreaking advances in developing and deploying two-photon polymerization (2PP) 3D printing — a key fabrication method for building complex microscale structures. His work combines laser pulse shaping with a custom-engineered metalens array, enabling printing that is faster, finer and more versatile than current commercial systems.
Since joining the Laboratory in 2019, Xia has played a key role in multiple Laboratory Directed Research and Development projects, including efforts that bridge additive manufacturing (AM) with high-energy-density physics and inertial confinement fusion (ICF) target production. He leads projects aimed at developing next-generation 2PP technologies that improve throughput, resolution and multi-materials printing capability using a suite of laser-based AM tools to build functional microstructures for applications in quantum computing, microfluidics, energy, responsive materials and ICF.
“I’m honored to be part of this year’s Innovators Under 35 cohort,” Xia said. “I’m grateful to the collaborators, mentors and entire support team at LLNL who have made our work possible. I really couldn’t think of a better place to work at. I am immensely grateful for LLNL’s unparalleled research environment for pushing the boundaries of AM and allowing me to explore ideas that would be difficult to pursue anywhere else.”
Xia earned his doctoral degree in materials science from the California Institute of Technology. He holds a bachelor’s degree in physics and in economics from the University of Chicago. His work spans both experimental and computational domains, drawing on expertise in ultrafast lasers, nonlinear optics and multiphoton polymerization to address technical challenges with national security relevance.
Each year, MIT Technology Review’s list highlights 35 innovators under the age of 35 whose work promises to have a profound impact on the world. Xia joins a distinguished group of past recipients, including Nobel laureates and founders of leading technology companies.
