Natasha joined us in March 2009 to lead the BBSRC-sponsored project on developmental genes in cestodes. Her most recent appointments include Sussex and Cambridge universities and she brings with her a wealth of experience in research directed at understanding the genetic underpinnings of animal form and function.

Alex arrived in October 2009 and is working with NHM collaborator Beth Okamura and myself on developmental biology in the vermiform cnidarian (myxozoan) Buddenbrockia. Alex is self-funded through a post-doctctoral fellowship by the German Academic Exchange Service (DAAD).
A primary objective of this project is to investigate the body-plan of the strange, vermiform, parasitic cnidarian, Buddenbrockia plumatellae. The affinities of this animal had long been obscure until evidence from gene sequence data and ultrastructure demonstrated it to be a member of the Myxozoa and this group as a subtaxon of Cnidaria (Okamura et al. 2002; Jiménez-Guri et al. 2007). A worm-like body plan is so far completely unknown from cnidarians, which usually occur as radially symmetrical sessile polyps or free-swimming medusae. In order to elucidate evolutionary changes that have occurred during the transition to a vermiform parasitic organism, we conducted investigations on morphological features like the musculature and nervous system. Current research is focused on the expression pattern of Hox genes, which are known to play an important role in axis specification in both cnidarians and bilaterians.

Magdalena obtained her PhD in Dec 2009 from the NHM and the University of Manchester, and in January began working on the Hymenolepis genome project with Matt Berriman's group at the Wellcome Trust Sanger Institute, outside Cambridge. She will soon begin a 9-month, SynTax-funded PDRA position to assemble and annotate the genome, characterize the Hox cluster, and begin comparative analyses with other flatworm genomes.
