His research interests span space geodesy, ring laser interferometry, time and frequency transfer, satellite tracking, and geodetic instrumentation. He develops high-precision systems for optical timing, photon counting, and co-location of geodetic techniques. His work contributes to global geodetic reference systems and fundamental metrology.

The recent publications highlight a strong focus on measuring Earth's rotation using large ring lasers (e.g., ROMY), developing optical event timers for satellite ranging, and advancing VLBI techniques for satellite tracking. There is a clear trend toward integrating multiple geodetic techniques and achieving sub-picosecond timing precision for improved geodetic accuracy.

Dr. Kodet has supervised master’s students, including Hanna, Maria (2022) on clock comparisons using event timers and Wong, Siow Kay (2018) on atomic clock synchronization via GNSS. His collaborative research involves institutions and projects like ESA, DFG (NEROGRAV, UPLIFT), and international geodetic networks. He is a key contributor to projects involving the Wettzell observatory, such as VGOS and fundamental station development.

His work is supported by involvement in major research initiatives including the DFG Research Unit NEROGRAV and the DFG Research Training Group UPLIFT, indicating active grant funding and participation in structured research programs.
