Judah Levine

Judah Levine is an Adjunct Professor at the University of Colorado and holds Fellow positions at NIST (National Institute of Standards and Technology) and JILA. His work focuses on developing statistical methodologies for timekeeping and frequency standardization, critical to maintaining global time synchronization.

Research Interests:

• Design and implementation of UTC(NIST), the US civilian time standard
• Advanced algorithms for calibrating atomic clocks and combining frequency standard data
• International collaboration with BIPM and global laboratories to unify timekeeping systems
• Development of high-precision time distribution methods for commercial, financial, and scientific applications
• Internet-based time services handling ~40,000 requests/second (3.5e9/day) and authenticated timing solutions

Key Contributions: His work supports NASA/JPL deep-space network timing, pulsar timing at radio observatories, and public time distribution infrastructure.
