Our People

Prof. Dale Gary is Distinguished Professor in Physics at NJIT, and Director of Solar Observatories. That includes the Big Bear Solar Observatory, an optical observatory in California with the highest-resolution solar telescope in the world, and also the Owens Valley Solar Array, a unique radio facility also in California dedicated to observing the Sun. Together, these two observatories are used to study the outer layers of the Sun from the surface outward. We especially study the way magnetic fields on the Sun affect solar activity such as solar flares, coronal mass ejections, and other events making up "Space Weather."  We also study how radio bursts from the Sun affect radio and cell-phone communications.  Prof. Gary teaches astronomy and physics courses at NJIT, as well as writing papers on his research to share with other scientists.

Prof. Gary received a B.S. in Physics in 1976 from University of Michigan, and a Ph.D. in Astro-Geophysics from U. Colorado, Boulder. He then spent 15 years at Caltech before coming to NJIT in 1997.
