Weijia Kuang earned his B.Sc in space engineering from Changsha Institute of Technology in China in 1982. He then obtained his M.Sc in theoretical physics at Wuhan University in China in 1985. He continued his graduate study at University of California, Los Angeles, and earned his Ph.D in applied mathematics in 1992.
After graduation, Dr. Kuang went to the Department of Earth and Planetary Sciences at Harvard University as a postdoctoral fellow and then a research associate. In 1998, Dr. Kuang joined the Joint Center of Earth systems Technology (JCET) at University of Maryland, Baltimore County, as a research associate professor.
In 2002, Dr. Kuang joined the Space Geodesy Branch in NASA Goddard Space Flight Center (GSFC) as a
geophycist/appled mathematician. He is currently leading the Core and Crustal Magnetics Group in theGeodesy and Geophysics Laboratory (61A) in NASA GSFC.
Geodynamo and planetary dynamos are the fundamental theories of the origins of the magnetic fields of the Earth, of other planets and moons in the solar system. They are also the keys to understand the spatial and temporal variations of planetary magnetic fields, their implications to the structures, the
dynamical processes from the deep interior to the surface, and to the planetary evolutions over geological time scales.
My interests in this discipline are on ground and satellite geomagnetic observations, global geomagnetic field modeling, and on geomagnetic variability due to oceaninc and lithospheric
processes.
Development and application of numerical algorithms and models in computational fluid dynamics.
Large-scale scientific computation on various distributive platforms.
This is a NASA ESI supported project on assimilation of geomagnetic measurments with MoSST core dynamics model (a geodynamo and planetary dynamo developed at Harvard and in GSFC over the past two decades) using an ensemble Kalman Filtering algorithm.
This is a NASA ESI supported projects on investigating core-mantle interactions and their implications to length-of-day (LOD) variation and polar motion on decadal time scales, via geodynamo (MoSST) and geomagnetic data assimilation (MoSST_DAS) modeling efforts.
This project is on utilzation of Swarm magnetic data product for studying core dynamics and for geomagnetic data assimilation.
This project focuses on simulating potential cubesat/cubesat constellation based geomagnetic missions, focusing on the data quality and sience values for studies of Earth's magnetic variability and its implications on dynamical processes in the Earth's liquid outer core and in the oceans on the surface.
This project aims at develop a prototype next-generation field model based on geomagnetic measurements and geomagnetic data assimilation results, and applications to magnetospheric circulation modeling.
Have supervised many graduate students and post doctoral fellows over the past 17 years in NASA GSFC and at various domestic and international universities.
