DESCRIPTION:My work focusses on the impact of sex and gene flow on the pro
 cesses of adaptation and speciation\, and I use experimental speciation to
  study this. The evolution of strong reproductive isolation is fundamental
  to the origins and maintenance of biological diversity. Speciation is the
  result of evolutionary processes that generate barriers to gene flow betw
 een populations\, facilitating reproductive isolation. The progression and
  outcome of speciation depend on interactions between evolutionary forces 
 that act with varying importance over space and time to either facilitate 
 or impede the evolution of reproductive isolation. Over the past decade\, 
 speciation genomics has provided better predictions on how barrier loci sp
 read in the genome and how speciation-with-gene-flow can occur. However\, 
 these developments remain difficult to test in natural populations and hav
 e not been widely adopted in experimental speciation research. Experimenta
 l speciation promises to be an excellent complement to snapshot studies of
  natural populations because it can disentangle recurring problems that co
 nfound studies of natural populations. Here I will introduce my study syst
 em\, using an evolve and resequence approach in monogonont rotifers to und
 erstand how evolutionary forces influence the speciation process.
