Solar physics, especially flare physics. Most of my work focused on radio emission of the Sun. In the recent years, I spent most of my time working on coherent radio bursts, which are believed to be intimately related to magnetic energy release during flares. These coherent bursts are characterized by their very high brightness temperature and narrow frequency bandwidth, and carry important information about particle acceleration, transportion, and dynamics. Data from radio spectrometers and interferometers were used to study their spectral and temporal structures in order to understand their emission mechanisms and their roles in flares. Multi-wavelength data were also used to disentangle the complexities of solar flares, e.g., optical, UV/EUV, SXR, HXR. I am going to participate in the commissioning work of the Expanded Very Large Array (EVLA) for solar observations. In the very near future, I expect to observe the Sun with the EVLA's unprecedent bandwidth, spectral resolution, time resolution, and spatial resolution.
