The biochemist Dr. Jonathan Hodgkin (born August 24th 1949) surrounded by petri dishes containing the nematode Caenorhabditis elegans at the Medical Research Council's Laboratory of Molecular Biology in Cambridge, UK. Hodgkin, the first student to gain a doctorate through study of C. elegans, is researching how the genes of this tiny soil- dwelling worm control its gender. Unlike its closest relatives, most specimens of C. elegans are hermaphrodite (having both male and female reproductive organs), with full males appearing, rarely, as a mutation. Hodgkin's work is part of a larger project to decode the genome, the genetic blueprint, of this simple multicellular animal.
