RESEARCH INTERESTS AND EXPERIENCES/ACHIEVEMENTS

Interests: Earth/Planetary rotation dynamics and gravitational variations. Global changes in geophysical fluids. Global geophysics and seismology. Digital data analysis and inverse/inference theories.

Major Experiences/Achievements: Six months of research cruises in Western Pacific and Indian Oceans for marine seismology (1976-1977). Developed an (autoregressive) numerical method for estimating the complex frequencies of decaying/growing sinusoids from time series (1981; with Gilbert). First to identify the correlation between interannual length-of-day variation with El Nino/Southern Oscillation (1984) and with quasi-biennial oscillation (1989). Developed the theory and algorithm to compute co-seismic excitation of Earth rotation and gravity field variations using normal-mode theory, and the definitive estimation of the 2004 Sumatra earthquake thereof (1987, 2005; with Gross). Developed the spherical-harmonic theory of time-variable gravity change due to Earth’s mass transports (1988). The first proposed idea of time-variable gravity detection using space-borne satellite-to-satellite laser interferometry (1992; with Colombo). First to study the influences of artificial reservoir water impoundment of Earth rotation and global gravity (1988, 1991, 1995). First definitive identification of the influence of diurnal/semidiurnal ocean tides on Earth rotation (1994; with Ray). Detection of the 1998 anomaly in Earth’s oblateness variation (2002; with Cox).
