Where do we come from? What is our ancestry? My research program is focused on evolution of the deuterostomes, that major division of the animal tree of life that includes the vertebrates (and man). Deuterostomes consist of three major phyla: the echinoderms (sea urchins, sea cucumbers and their cousins), hemichordates (acorn worms and pterobranchs) and chordates (including the vertebrates). My greatest interest is in deep events within deuterostome evolution, including the question - what was the nature of the basal deuterostome? My studies have suggested that the ancestral deuterostome may have resembled an enteropneust hemichordate worm. My research program uses a multidiscipinary approach, including organismal and molecular biology, fluid mechanics, and paleontology to test this hypothesis.

我们来自哪里？我们的血统是什么？我的研究计划的重点是氘化的演变，即脊椎动物（和人）在内的动物树的主要分裂。氘抑制剂由三个主要的门组成：棘皮动物（海胆，海参及其堂兄），半色（Acorn蠕虫和pterobranchs）和和弦（包括脊椎动物）。我最大的兴趣是对杜特罗斯群落进化中的深层事件，包括问题 - 基础氘代表的本质是什么？我的研究表明，祖先的氘代表可能类似于肠内半身蠕虫。我的研究计划使用多学科方法，包括生物和分子生物学，流体力学和古生物学来检验该假设。
