My work and general research interests concern the application of molecular and computational tools within a phylogenetic framework to interpret organismal diversity (in fish particularly) and to understand mechanisms of evolution. Currently, I'm emphasizing on marine phylogenomics (see Chen and Mayden 2010; Chen, Samadi, and Chen 2018; Parey et al. 2023), exploration of marine biodiversity (see Lee et al. 2019; Chen et al. 2016, 2017), biogeography (especially, in studying the origin of the Coral Triangle’s extreme concentration of marine biodiversity in relation to geological, climate and evolutionary events, See Chen and Borsa 2020; Lim et al. 2021), evolution of deep-sea metazoans (see Lee et al. 2019), and marine conservation (see: e.g., Kong et al. 2023; Samadi et al. 2015).

NTU-IRD jointed project on the phylogeography and systematics of emperors and large-eye seabreams and other coral reef fishes 


During my doctorate study (at Laboratoire d’Ichtyologie générale et appliquée and Service commun de systématique moléculaire, Muséum National d’Histoire Naturelle (MNHN) à Paris under the supervision of Dr. Guillaume Lecointre), my research was focused on a systematics project of acanthomorph fishes, the most diverse group of vertebrates. My work was the first attempt to summarize multi-locus data for an extensive taxonomic sampling of acanthomorphs (Chen et al. 2003). I also worked on small-scale phylogeny of higher notothenioids (Antarctic acanthomorphs, composed of the families Harpagiferidae, Artedidraconidae, Bathydraconidae, and Channichthyidae) based on two mitochondrial genes (Chen et al. 1998; Derome et al. 2002). The comparison with phylogeography and ecology of included channichthyid taxa allowed proposing putative speciation models and correlations with paleo-events of Antarctic Ocean (Chen et al. 1998).

I embarked on my first postdoctoral training at the University of Nebraska-Lincoln to further horn my skills on molecular techniques and molecular systematics of fishes (López et al. 2004). Later, I had a short stint as a postdoctoral fellow at University of Konstanz in Germany where I worked on projects of EVODEVO (evolutionary development) in cichlids and phylogenomic analysis of fish model systems (Chen et al. 2004). Besides, a collaboration work (with Dr. Jing Luo) on molecular systematics and biogeography of Oriental Voles (Genus Eothenomys, Muridae, Mammalia) was accomplished (Luo et al. 2004).

I also expand my extensive experience in Molecular Systematics studies to the investigations of micro-evolution and Molecular Ecology using grapevine downy mildew (Plasmopara viticola) as model system (Chen et al. 2007; and others). This research activity was conducted at French National Institute for Agronomic research (INRA, Bordeaux).

Prior to my current position, I have been working on the US NSF funded AToL study on the Cypriniformes Tree of Life (CToL) at St. Louis University (Chen et al. 2008; Chen and Mayden 2009; Chen et al. 2009; and others).
