Institute of Evolution & Marine Biodiversity, OUC

The Institute of Evolution & Marine Biodiversity (IEMB), officially established in February 2010, is an inter-department institution mainly focused on studies of biodiversity, developmental biology and evolution of marine organisms. IEMB is one of the doctorate authorization units of National Key Discipline of Marine Biology with doctoral programs covering all fields of biology. IEMB has attracted international attention on several cutting-edge research fields, which cover evolution and biodiversity of various organisms.

Up to June 2020, IEMB has 46 faculty and staff members, including 24 full professors. Members of IEMB have won many academic titles, including Academician of Chinese Academy of Sciences, “Cheung Kong Scholar”, “Taishan Scholar”, and grants such as NSFC for Distinguished Young Scholars, for Outstanding Young Scholars, and 1000Plan Program for Young Talents.


Main research fields:

● Evolution and biodiversity of prokaryotic and eukaryotic microbes

Centered on studies of biodiversity, biogeography, cytology, phylogeny, epigenetics, population genetics and genome evolution of virus, prokaryotic and eukaryotic microbes, the main research interests include: (1) species diversity and taxonomy, developmental modes and pattern-formation during reproduction, relationships and systematic positions of taxa at class-order-family level within the phylum Ciliophora, epigenetic regulatory mechanisms, gene functions and molecular mechanisms in important physiological processes using model organisms such as Tetrahymena, Euplotes; (2) diversity, biogeography, biogeochemistry (including carbon, nitrogen and sulphur cycles) and the environmental adaptation of marine microorganisms (bacteria and archaea) in typical sea habitats such as deep-sea trench, hydrothermal vents and marginal seas; (3) biodiversity, community structure and function of virioplanktons as well as their interaction with hosts and environmental factors in China's offshore, polar and deep-sea waters, construction of the -omics databases of virioplanktons in different marine contexts; isolation, purification and genome analysis of strains of cyanophages and their hosts; discovery of novel strains and genes of viruses; picoeukaryotic biodiversity and community structure; (4) –omics and genetics studies on mutation and life history of marine microbial organisms, such as bacteria, yeasts and protists.

 Evolution, regeneration, development of model animals

Our mission emphasizes a creative, inter-discipline approach to the fundamental research into the mechanisms of evolution and development, especially organogenesis and regeneration, using model organisms such as zebrafish, Drosophila, amphioxus, marine tunicate and algae as model animals. Our current research interests include: (1) origin and evolution of neuroendocrine, immune and gustatory systems; (2) cellular processes, signal transduction and regulatory mechanisms of cilia biogenesis and related diseases, biological tube formation, aging, liver development, and cardiac regeneration; (3) growth-arrested mechanisms and immortalization of the cultured cells, and cellular and molecular mechanisms as well as evolutionary history of tissue/organ regeneration; (4) genetic basis and physiological mechanisms underlying environmental adaptation; (5) comparative and evolutionary immunology of fish with emphasis on analyzing the mechanisms driving the structural and functional diversities of key immune molecules and their evolution.

Diversity and systematics of marine organisms

Study in marine organisms’ morphology, taxonomy, biodiversity, genomics, phylogeny, and population genetics. The main research interests include: (1) morphology, taxonomy, DNA barcoding, phylogeography, speciation and evolution of selected marine invertebrates, such as nemerteans, cephalopods and echinoderms; (2) biodiversity and phylogeny of corals and poriferans, their microbial symbionts; structural and functional diversity and chemical ecology of their secondary metabolites; (3) in vitro cell culture and gene transfer of marine animals such as penaeid shrimps and crabs, mechanism of mitosis-arrest of in vitro cultured shrimp cells, molecular mechanism of tissue regeneration and regeneration-evolution of amphioxus and axolotl.
