     Some amusing quotes about research

     In the department of self-promotion (which actually I shy away from but....)

   "Seven things about...." from SDSU News Center

    Science fiction and the human condition


     March 11, 2015: My paper, "Spin-orbit decomposition of ab initio nuclear wavefunctions" has been published: Phys. Rev. C 91, 034313 (2015)

     November 5, 2014: I have a science fiction appearing in the December issue of ANALOG SCIENCE FICTION AND FACT.  You can read a sample of it here.

     August 18, 2014: I have started a blog, for posting essays on science, science fiction, and related topics.

     August 7, 2014: Micah Schuster (Ph.D student) wins award for best     summer student research poster at Lawrence Livermore National Lab. He also won the past two years.
