Donald Lubowich Ph.D. is an adjunct associate professor and coordinator of astronomy outreach at Hofstra University in the Department of Physics and Astronomy.

Dr. Lubowich earned a B.A. in astronomy from Northwestern University, an M.S. in plasma physics and fusion technology from Columbia University's School of Engineering, and an M.S. in physics and Ph.D. in astronomy from New Mexico State University. He has also been a senior scientist for the American Institute of Physics in its Scientific Publishing Center.



Dr. Lubowich's current research interests are the origin, formation and chemical evolution of elements to test models such as big-bang nucleosynthesis. He has studied deuterium (heavy hydrogen), lithium, boron, and fluorine using many of the world's largest optical and radio telescopes. He has published numerous scientific papers in Nature, The Astrophysical Journal, Nuclear Physics and The Physical Review.

Articles about his published research "Deuterium in the Galactic Centre as the result of recent infall of low-metallicity gas" (Lubowich et al., 2000, Nature, 405, 1025), which showed that deuterium from the Big- Bang is continuously falling ("raining") into the Galactic Centre, have appeared in The Boston Globe, Newsday, Astronomy Magazine, Astronomy Now Magazine, the Italian science magazine Galileo, the National Geographic Society Web site, and the BBC Web site, and his research has been translated into 13 foreign languages.


Teaching at Hofstra since 1980, Dr. Lubowich was appointed coordinator of astronomy outreach in 2005. During that year, Hofstra's Astronomy Outreach Program began a monthly "Stars on Sundays" stargazing event for the general public at Hofstra's Observatory atop the Chemistry and Physics Building. He also created a "Music and Astronomy Under the Stars" program for the Town of Oyster Bay, pairing telescopes with free outdoor summer concerts. In addition, he has conducted astronomy demonstrations/telescope observations for the Fresh Air Fund Summer Camps (for children from low-income families), synagogues and churches.

Classification of Pluto

Dr. Lubowich and was one of 500 astronomers in the world that voted to reclassify Pluto as a dwarf planet. Dr. Lubowich believes that Pluto should still have full planet status because it has three moons, a methane atmosphere (larger than the atmospheres of Mercury), and an interior structure.


Dr. Lubowich is a member of the American Astronomical Society, the American Physical Society, the Astronomical Society of the Pacific, and is a member of the International Astronomical Union.
