Daniel W. Armstrong

Daniel Wayne Armstrong (born November 2, 1949 in Fort Wayne ) is an American chemist ( analytical chemistry , pharmaceutical chemistry, colloid chemistry).

Armstrong is the son of Fort Wayne Mayor Robert E. Armstrong. He studied at Washington and Lee University with a bachelor's degree in 1972 and Texas A&M University with a master's degree and doctorate in chemistry in 1977. He was then an assistant professor at Bowdoin College and 1980-1983 at Georgetown University . In 1983 he became associate professor and later professor at Texas Tech University and in 1987 professor at the University of Missouri at Rolla. In 2000 he became a professor at Iowa State University , where he became a Caldwell Distinguished Professor . In 2006 he became a professor at the University of Texas at Arlington , where he is the Robert A. Welch Distinguished Professor .

He is known for methods of separating enantiomers using liquid chromatography and is considered the father of pseudophase separation (based on micelles or cyclodextrins ). He is also involved in pharmaceutical chemistry, environmental chemistry and bio-organic chemistry, including cyclodextrins (development of the first chiral recognition process for these), surfactants , molecular weight determination with chromatography for macromolecules, chemistry of macrocycles with application to antibiotics as chiral selectors. More than 30 column chromatography processes (gas or liquid) developed in his laboratories have been used commercially. Later he developed efficient microfluidic analysis methods for colloids and microorganisms. He developed models for room temperature ionic liquids (RTIL) and their application in analytical chemistry.

Armstrong is co-editor of Analytical Chemistry .

He received the EAS Award in Chromatography, the Martin Medal, the ACS Award for Separation Science & Technology, the Midwest Award in Chemistry from the American Chemical Society (1993) and the Presidential Award for Research and Creativity (1994). In 2003 he received the Chirality Medal . He is a member of the American Association for the Advancement of Science , Fellow of the American Chemical Society and the Royal Society of Chemistry. In 2001 he became an honorary member of the Slovak Pharmaceutical Society. Daniel Armstrong is one of the world's most highly cited chemists according to the Science Citation Index.

In 1994 he founded the We're Science series on National Public Radio and moderated it. In 1998 he received the American Chemical Society's Helen M. Free Award for Public Outreach.
