The 2017 Talanta medal is awarded to Purnendu "Sandy" Dasgupta of the University of Texas at Arlington in recognition of his world-leading research in the field of analytical chemistry. "This is a tremendous honor and I'm very grateful for this recognition by my peers," Dasgupta said. "By recognizing me, they are also honoring several generations of my students from all over the world, who are so involved and committed to my work and form a cornerstone of my success." Dasgupta's work covers many areas of science from blood tests to detecting arsenic in water. He is currently working on the rapid analysis of trace heavy metals in the atmosphere, iodine nutrition in women and infants as well as developing ion chromatography for testing materials on other planets, such as soil on Mars.
