Research Talk at IBCAS Youth Forum

Wed, 25 Sep 2019 00:00:00 +0000

I had the great honor and was invited by Dr. Zhiduan Chen to visit his lab. We had great conversations and we also discussed to collaborate a few great project in comming futher.

Later on I was invited by Dr. Limin Lu, who hosted a Youth Forum organized by the State Key Laboratory of Systematic and Evolutionary Botany (LSEB) at IBCAS.

I briedly introduced my research works conducted in these 5-year post-doc life in Soltis Lab. I used rosids as an example to illustrate how to build and use large-scale phylogentic trees. Key points are:

Data mining public database (e.g, GenBank and GBIF), and data cleaning for downstream analyses. E.g, recent manuscript in bioRxiv and paper in AJB.
Knowing the potential issues when applying large-scale data for macro-ecology and -evolution. E.g., papers in AJB, Ecology, and another recent manuscript in bioRxiv.
Large-scale trees can be used for [Diversification]. E.g., recent manuscript in bioRxiv and an accepted paper collaborated with Dr. Xue.
Large-scale trees can be used for Phylogentic Diversity (PD)

Relationships matter!!

Please let me know if you have any questions and want to know more details.

Overall, it turned out full house!! More than expected!! ✌️ ✌️

Especially I have met Prof. Jianfeng Mao from Beijing Forestry University. I had great cinversation with him and his students.

All my research is phylogeny based. Phylogeny trees are illustrating relationships among organisms. Relationships matter! In my understanding, phylogeny serves as a beautiful platform, which links all the biology data together with an evolutionary background. I’m insterested in phylogeny of angiosperms, particularly rosids.

I briedly introduced three main research interests:

It turned out that people like my talk! ✌️ ✌️

Rosid Phylogeny and Diversification

Mon, 10 Dec 2018 00:00:00 +0000

We recently used large biodiversity datasets representing the state of the art in rosids to explore (1) phylogenetic and dating uncertainties, and sampling bias persisted in major flowering plant clades, and (2) the impacts of incomplete sampling schemes on different diversification methods; (3) with deep understand of our data and methods, we then further explored the association betweed rosid diversification and tropicality, and both historical and present-day temperature.

As more molecular data, species distribution data, and other ecological data available, we’ll continously work on developing climatic layers over time that can trace the expansion of strong seasonality, and especially areas with seasonal freezing temperatures. These layers, when coupled with more fine-grained, modeled past and present species distribution information would provide a strong basis for more explicit testing of current pattern with more mechanism-focused hypothesis.
