Rolf Hoekstra from the Netherlands will be on sabbatical in my laboratory beginning January until mid April (leaving just before Easter). He works on fungal genetic systems. His current interests include somatic (in)compatibility, spore killing (meiotic drive) , fungal senescence (associated with mitochondrial plasmids) and population level effects of toxin secretion. A sample of his published work is given below, as well as his permanent affiliation and address.

He needs housing. His budget allows for rental of a house and this is his first preference. A 2 bedroom apartment would also work. His wife will be with him and he may have guests visiting also. I know him well and he is a wonderful person, very warm and personable. If you would like more information you may contact me or write him directly at Rolf.Hoekstra@POPGEN.EL.WAU.NL
