Changyi Tan received
a B.S in Astronomy in 2001 from Nanjing University and an M.S. degree in Plasma Physics in 2004
from the Institute of Applied Physics and Computational Mathematics
in Beijing. He completed his Ph.D. in Applied Physics at the Space
Weather Research Lab at the New Jersey Institute of Technology.
In January 2010 Dr. Tan was hired by I.M. Systems Group Inc.
Maryland. He currently works at NOAA / NESDIS / STAR doing
research on space weather, processing satellite data and
transitioning ACE and GOES NOP systems from QNX/Windows to Linux.
From 2004-2010, Dr. Tan was a Research Assistant in Space Weather
Research Lab, Center for Solar-Terrestrial Research, NJIT. Research
the relationship between solar photospheric magnetic fields and
associated coronal activities or solar flares - it can be utilized in
solar flare/CME prediction and space weather forecasting:
Adopted ordinal logistic regression concept and developed a
new method to predict destructive solar flares for the space weather forecasting.
Examined the relationship between solar photospheric magnetic
parameters and solar flare productivities and found the
important physical link.
Examined the correlation between solar photospheric magnetic
parameters and associated coronal responses, and proved an
important solar coronal heating mechanism.
Examined the relationship between large solar flares, halo
coronal mass ejections (CMEs) and strong geomagnetic storms,
and theoretically established an automatic system to alarm the
disasters of space weather.
Studied the evolutions of solar optic penumbral flows and
shear flows associated an X3.4-class flare on December 13,
2006 and concluded the flows decrease during the flare which
is a brand-new finding in solar physics, it might be a
precursor of solar flare which can be utilized to predict
