Ernst Zinner, Donald Clayton, Bob Walker, Frank Podosek Brad Meyer, Ernst Zinner and Don Clayton participated in all workshops. Larry Nittler is a previously graduate student of our group. He continues to work on stardust.

Ernst Zinner and Roy Lewis. We have collaborated with Roy Lewis (University of Chicago) since 1987. His work with Ed Anders was instrumental in identifying presolar dust grains.
Brad Meyer, Roberto Gallino, Donald Clayton. The Conference on Isotopic Anomalies at Clemson University organized by astrophysicist Don Clayton was the first of the series of Clemson - Washington University workshops. Together with Timmes he has contributed an article on galactic chemical evolution for the book "Astrophysical Implications of the Laboratory Study of Presolar Materials". Over the years Clayton has been a tireless champion of presolar dust grains from meteorites (see articles in PSR Discoveries and SF Gate Science). We have collaborated with Roberto Gallino (University of Torino) since 1991. Astrophysicist Gallino is an expert on s-process nucleosynthesis, which takes place in Asymptotic Giant Branch (AGB) stars. Together with Busso and Lugaro he has contributed an article on neutron-capture nucleosynthesis for the book "Astrophysical Implications of the Laboratory Study of Presolar Materials"
Roy Lewis, Tom Bernatowicz, Donald Clayton.
Robert Walker, Sachiko Amari, Joyce Brannon, Jim Truran. Truran, an astrophysicist from the University of Chicago, has participated in several of the workshops. He, together with Starrfield and Gehrz, has contributed an article on nucleosynthesis in nova for the book "Astrophysical Implications of the Laboratory Study of Presolar Materials".
Donald Clayton, Tyrone Daulton, Charles Hohenberg, Robert Nichols, Andy Davis. Tyrone Daulton (Naval research Laboratory) is a previous graduate student of the Physics Department. Although mostly working on other topics, he is pursuing TEM studies of presolar dust grains. For several years we have been collaborating with Andy Davis (University of Chicago) and Michael Pellin (Argonne National Laboratory - see picture #2). With the CHARISMA instrument at ANL they can measure isotopic ratios of heavy elements such as Zr, Mo and Ba in individual presolar grains by resonance ionization mass spectrometry (RIMS) (see e.g. LPSC XXXI abstracts 11 and 12).
