About

Dr. Zenghu Chang is a pioneering physicist whose research spans ultrafast laser science, attosecond physics, and advanced instrumentation for extreme environments. He is best known for his groundbreaking work on generating and controlling isolated attosecond pulses—the shortest bursts of light ever created—enabling real-time observation of electron dynamics in atoms and molecules. His contributions include the development of the double optical gating technique, which revolutionized attosecond pulse generation by making it more reliable and accessible. With over 25,000 citations, his work has profoundly impacted ultrafast optics and quantum physics. Notably, his early-career invention of the rotary hammer ultrasonic/sonic drill system (25 citations) for planetary robotic missions demonstrates his versatility, addressing critical needs for subsurface sampling on Mars and beyond. Dr. Chang’s achievements have earned him prestigious honors, including the American Physical Society’s Arthur L. Schawlow Prize in Laser Science and a fellowship in the National Academy of Inventors. His research continues to push boundaries, from attosecond metrology to next-generation laser-driven particle acceleration, inspiring students and researchers to explore the fastest timescales in nature.
