Maggy Wotten at SLSDr. Meloni sends graduate student to Switzerland to perform research.

Dr. Giovanni Meloni sent Maggy Wooten, a graduate student researcher in his lab, to perform research at the Paul Scherrer Institute (Swiss Light Source) near Zurich, Switzerland this past summer. Dr. Meloni sent another graduate student to perform research at the Swiss Light Source in 2012.

Congratulations Students!

Kenneth Smith started a Ph.D. program at Johns Hopkins University while Joseph Czekner started at Brown University this past year. Also attending Ph.D. programs are Martin Y. Ng at the University of Pennsylvania, Amelia Ray (December 2010) at UC San Diego and Matt Greaney at USC working in Richard Brutchey's research lab.
