New Branches at the Tree of Life

03.02.2015 - (idw) Heidelberger Institut für Theoretische Studien gGmbH

Biologist Emily Jane McTavish (University of Kansas) does evolutionary research using DNA sequence data and computational tools. She is visiting the Heidelberg Institute for Theoretical Studies (HITS) on a fellowship by the Alexander von Humboldt Foundation. In December 2014, Dr. Emily Jane McTavish from the University of Kansas joined the Heidelberg Institute for Theoretical Studies (HITS). She will work with the Scientific Computing Group (SCO, leader: Alexandros Stamatakis) for nine months. Her stay is funded by a Humboldt Research Fellowship for Postdoctoral Researchers. This program allows postdoctoral researchers to carry out long-term research in Germany. Applicants choose their own topic of research and their academic host.

The New York-born scientist is interested in phylogenetics, genomics, and programming. At the moment, she is working on software that can be used to extract evolutionary relationships from large data sets and to analyze this data. With the advent of new technologies, genomic DNA sequence data is being generated very rapidly but researchers also require new tools to analyze all of this data. They need special computational methods to handle the amounts of information. The Stamatakis lab, who I am here working with, have developed some of the best tools available for phylogenetic analysis and Im excited to learn from them, says 31-year-old Emily Jane McTavish. Alexis Stamatakis and the SCO group have a lot of expertise in rapid analyses of very large data sets. By working with them I can improve my computational skills and apply the tools they have developed to my own research.

Before coming to Heidelberg, the daughter of two Canadians spent one year as a postdoc at the University of Kansas. She is also part of the Open Tree of Life Project which aims to build a comprehensive tree of all 1.8 million named species. An extraordinary feature of this tree is that it will be constantly updated and revised as new phylogenetic data comes in. To ensure the long-term future of the project, being able to rapidly update data is indispensable this is another reason why her stay at HITS will be highly beneficial for Emily Jane McTavish. She does not only want to deepen her computational knowledge but also learn new methods that will help me to find answers to the questions that I am particularly interested in: How does evolution happen? And what processes have led to the species diversity we see today?

The research group Scientific Computing (SCO) at HITS develops computational methods and tools to create and analyze phylogenetic trees of all kinds. The scientists have designed new algorithms and software for the evolutionary tree of insects and birds. The findings of their studies were recently published in the academic journal Science.

The Heidelberg Institute for Theoretical Studies (HITS gGmbH) was established by SAP co-founder Klaus Tschira and his foundation, the Klaus Tschira Stiftung, as a private, non-profit research institute. HITS conducts basic research involving the processing, structuring and analysis of large amounts of data in the natural sciences, mathematics and computer science. The research topics range from molecular biology to astrophysics. Shareholders of HITS are the HITS-Stiftung, Heidelberg University and the Karlsruhe Institute of Technology (KIT). HITS cooperates with universities and research institutes, as well as with industrial partners. The Klaus Tschira Foundation provides the major financial support for HITS through the HITS foundation. The main external funding sources are the Federal Ministry of Education and Research, the German Research Foundation and the European Union.
