Dave whose background you might know almost too wall tom have —
considered seriously. Buring the past four or fiv. years, ha has moved
avay eitirely from protosoan genetics, and is making an increasingly
good reputation in hie work with bacteria. I know Dave is interasted
in an acelamic positioa, and “with a Tittle stretching of the _ Vaoancy
you hav. 4t might ba possible to Make a mutually happy arrangement. I

rently working on the rola tionehls cf miclear DMA to cytoplasmic Ria”
in Tatrehymena and 1h bacteria. tcok his Ph.D, ‘with Luria on "Genetic
furctions cf prophage-—- interference with the multiplication of hetero-
logous bactericphugas" , which is the €itl. of his dissertation, about

fications from Luria oid from Masia. I know hie im iaterosted in a position
where he can coatim his research and als¢ develop a cours, in General
