Brief Bio


Dr. Zheng joined the Space Weather Laboratory as a research astrophysicist in February 2010. After finishing her Ph.D degree in physics from the University of New Hampshire in 2001, she came to Goddard as a postdoctoral researcher. In 2005, she took a position at APL and worked there as a scientist before returning to Goddard in 2010.

Dr. Zheng’s research experience includes ring current/radiation belt modeling, subauroral electric fields, space weather physics and modeling, ULF waves in the tail, ionospheric outflow, dayside magnetopause reconnection, field-aligned currents in the auroral zone, and multipoint data analysis of the broad magnetosphere and ionosphere system. Dr. Zheng has authored/co-authored over 30 peer reviewed journal publications. Dr. Zheng has served as principal investigator on NASA-Geospace and NSF grants, and as co-investigator on several other NASA/NSF grants. She has been a lead session convener for the Fall 2007, 2009 AGU meetings, 2012 AOGS and 2013 Meeting of Americas and guest editor for a JASTP special issue. She has served on NASA and NSF proposal selection panels. She has been the lead/main organizer of the 3rd (2011) and 4th (2012) annual NASA Space Weather and Robotic Mission Operations Workshop.

Dr. Zheng has been involved in providing/improving space weather services to NASA robotic missions, including planetary missions. One of her current interests is to expand her research domain by analyzing space weather events from a broader perspective -- starting with the originator, the Sun -- to understand the full chain of physical processes involved in initiation and propagation of space weather events and their effects throughout the interplanetary space, combining modeling results and observations.

She has been a strong proponent of the NASA Space Weather Research Center and has served as a mentor to many high school and college interns. In addition, she has been heavily involved in CCMC/SWRC educational initiatives. In 2012, she gave several NASA Hyperwall presentations concerning space weather at the AOGS meeting and attended several public outreach events.
