I am a research associate at the Stanford-Lockheed Institute for Space Research. I did my postdoc in the RHESSI group at NASA Goddard Space Flight Center, working with Drs. Brian Dennis and Gordon Holman. I graduated from Stanford University with a PhD on particle acceleration in solar flares advised by Professor Vahé Petrosian.

Research [my ADS: Articles, All (articles + abstracts)]:

My scholastic background encompasses various areas that fall under the heading of solar physics. My observational work covered a broad wavelength range from visible light to hard X-rays, while my numerical and theoretical work involved both fluid and kinetic descriptions of plasma. My master's thesis focused on the eruption mechanisms of solar prominences using MHD simulations. My early doctoral research included analyzing MDI magnetic field data using wavelet techniques and studying CMEs with phenomenological and MHD models. A growing interest in the physics of particle acceleration led to my dissertation work on solar flares, concentrating on analysis and interpretation of hard X-ray data as well as theoretical modeling with the combined Fokker-Planck and hydrodynamic code. My postdoctoral work in the RHESSI group at Goddard improved and extended my graduate study in solar flares. A list of projects I worked on is as follows.

Particle accelerations in solar flares - RHESSI data analysis and modeling:
(1) A statistical study of hard X-ray imaging spectroscopy of limb flare loop top and foot point sources, in an effort to put constraints on our particle acceleratoin models. See my 2003 AAS/SPD Poster ( HTML, PDF).
(2) RHESSI Observations of a Simple Large X-ray Flare on 11-03-2003 (ApJ, 611, L53-L56, August 10, 2004, ADS, PDF)
(3) Evidence of chromospheric evaporation revealed by RHESSI (ApJ, 649, No. 1, Oct, 2006, ADS, PDF)
(4) Double Coronal X-ray Source and Magnetic Reconnection Site (ApJ, Vol. 676, p. 704-716; March 20, 2008, ADS, PDF).
See the related RHESSI Science Nugget , and my 2007 Fall AGU poster, PPT, PDF.
(5) Conjugate Hard X-ray Footpoints in the 2003 October 29 X10 Flare: Unshearing Motions, Correlations, and Asymmetries
(Accepted by ApJ Nov. 05, 2008, ADS, PDF ).
Coronal Mass Ejection (CME) modeling:
