S. H. Ashworth

Stephen H. Ashworth is a Lecturer in the School of Chemical Sciences and Pharmacy at the University of East Anglia, UK. He received his B.A. degree in chemistry from the University of Oxford in 1988 and his D.Phil. degree also from Oxford, in 1992. During 1992-1993, he worked in the Joint Institute for Laboratory Astrophysics (JILA) and the National Institute for Standards and Technology (NIST) in Boulder, Colorado. In 1993, he went to work at the Max-Born Institute for nonlinear optics and ultrafast spectroscopy in Berlin, Germany. Since 1996 he has been an Engineering and Physical Sciences Research Council Advanced Fellow at Bristol University, UK. During that Fellowship, he moved to the University of East Anglia and was awarded a Lectureship in 2001. His current research interests include the spectroscopy of small gas phase transition metal compounds and the application of lab base spectroscopy to atmospheric chemistry.
