On the Web of Science my name appears sometimes as Suo Z and sometimes as Suo ZG.  If I search for Suo Z*, papers by a biologist named Suo ZM mix in.  Now Suo is a very rare name.  I cannot imagine how Wang JS searches for his papers.  Last year Michelle Oyen and I talked about assigning a unique identifier to each researcher, much like assigning an ISBN to each edition of a book, or assigning a DOI to each paper.
