Dicyemid mesozoans were studied on taxonomy, phylogeny, and co-evolution.(1) Taxonomy: Ten new species of dicyemids were found in five species of cephalopods,Octopus hubbsorum, O.longispadiceus,Sepia lorigera,Sepioteuthis australis, andSepioloidea lineolata(2): Cell differentiationin dicyemids: To provide insight into the functional differentiation, using whole mount in situ hybridization the expression patterns of 16 genes were analyzed. Some possible functional differences among cells were found in vermiform stages and infusoriform larvae.(3) Mitochondrial genomes of dicyemids and plachozoans: Mitochondrial genomes of dicyemids and plachozoans were studied, several mini-circle DNAs were found in dicyemid mitochondria, and the wholemitochondrial genome of plachozoans was revealed.(4) Relationship between dicyemids and cephalopods: The phylogenetic trees of dicyemid species and the host cephalopods revealed that dicyemids and cephalopods did not co-evolved. Some dicyemid species switchedthe host species, some co-speciated with the host cephalopods.

对双胞动物中生动物进行了分类、系统发育和共同进化研究。(1)分类：在头足类章鱼、O.longispadiceus、Sepia lorigera、Sepiothius australis和Sepioloidea lineolata等5种头足类动物中发现了10个双胞动物新种(2) ：双氰胺中的细胞分化：提供深入了解功能分化，利用整体原位杂交分析了16个基因的表达模式。在蠕虫状阶段和滴虫状幼虫中发现细胞之间可能存在一些功能差异。(3)双线虫和扁形动物的线粒体基因组：对双线虫和扁形动物的线粒体基因组进行了研究，在双线虫线粒体中发现了多个小环DNA，并研究了双线虫和扁形动物的线粒体基因组。 (4)双胞菌纲和双胞纲动物的关系头足类动物：双头足类物种和宿主头足类动物的系统发育树表明，双头足类动物和头足类动物并不共同进化。一些双壳类物种转换了宿主物种，一些与宿主头足类动物共生。
