During his tenure at Pfizer, Dr Castle also led a team that successfully stably expressed and a ran a drug candidate discovery campaign against this historically challenging Nav1.9 sodium channel, which is currently receiving considerable interest as a potential target for new pain therapies due to human genetic pain disorders being recently associated with mutations if this channel. Prior to its acquisition by Pfizer in 2011, Dr Castle served as Director of Biology and Senior Research Advisor of Icagen for more than a decade, participating in and/or leading a broad spectrum of ion channel focused drug discovery programs targeting neuroexcitatory, cardiovascular and immune/inflammatory disorders. Prior to Icagen, Dr Castle spent 8 years at Harvard Medical School, first as a Post-Doctoral Fellow and then as an Assistant Professor.
