Ihsan Ali Al-Shehbaz

In 1962, Al-Shehbaz earned a Bachelor of Science degree from Baghdad University. He pursued graduate studies in the United States, gaining a Master of Science degree from Harvard University in 1969 and a Ph.D. from Harvard in 1973.[1][5]

Prior to his current professorial and curatorial position, Al-Shehbaz was a professor and director of an herbarium at Baghdad University, a professor and director of a herbarium at Sulaymaniyah University in Iraq, and a postdoctoral fellow at Harvard University's Arnold Arboretum. In 1992, Al-Shehbaz edited all botanical entries for the third edition of the American Heritage Dictionary.[5] He has worked on major projects about the Flora of North America and, with the help of the Chinese botanists, the Flora of China.[6][7][8] In regard to the latter, Al-Shehbaz said:

By unlocking the knowledge of China's great botanical treasures for the rest of the world, the project brings together hundreds of Chinese and Western scientists for an invaluable exchange of ideas, training, information, and plant specimens. It is an enormous advancement for systematic and applied botany ... China's plant species represent a significant percentage of the world's total. If we don't do this kind of research, how will we know what we have and how to protect it?[7]

Al-Shehbaz's primary academic interests are the phylogeny and systematics of the family Brassicaceae, especially in the Himalayas, Central Asia, and the Americas with emphasis on the South American and Chinese members.[6][7] He also has an interest in conservation and the preservation of biological diversity. According to Al-Shehbaz, if "we want to have a peaceful world, to live in harmony, we have to know how to cooperate, both with humans and with other species."[7]

Al-Shehbaz has described ten new genera previously unknown to science.[7] He has described over four hundred plant species[1] and more than seventy of them were previously unknown.[7] Al-Shehbaz has called botanical science "a race with time to document what's there before it's gone."[7]

Alyssum, Arabidopsis, Arabis, Armoracia, Barbarea, Boechera, Draba (of which he revised many South American members[6]), Erucastrum, Nasturtium, Raphanus, Rorippa, Schizopetalon, Sisymbrium, and Tropidocarpum are among the genera in which he has identified plant species. Some specific plant species Al-Shehbaz has identified include Cardamine lojanensis, Draba ecuadoriana, and Draba steyermarkii.[1][8]
