Carnegie Fellow Frank Gyngard joined DTM this month after finishing his Ph.D. in physics at Washington University, St. Louis. His research interests are focused on multi-element isotopic studies of presolar grains. Specifically, he has worked to determine, for the first time, the cosmic ray exposure ages of individual grains by measuring Li isotopic ratios in presolar SiC grains. Along with Larry Nittler, Gyngard has been involved in the development of a new automated measurement system for the NanoSIMS ion microprobe that is being used to search for ultra-rare presolar grains. While at DTM Gyngard will continue to apply micro-analytical techniques to search for grains with isotopic compositions that push the limits of our current understanding of nucleosynthesis in stars.
