Welcome!

Welcome to the Mathematical Genomics group at RIKEN, Japan’s national scientific research institute.
We are part of the Center for Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS).

Please get in touch if you’re interested in joining us in Tokyo. See here for RIKEN-funded fellowships and JSPS-funded fellowships at PhD and postdoc level, in addition to positions funded directly by us.

当研究室の研究にご興味のある方は、どうぞお気軽にご連絡ください。

博士課程やポスドクへの応募を希望される方は、英語の履歴書をメールでお送りください。 当研究室の募集に加え、理化学研究所の「基礎科学特別研究員制度」「JRA制度」や、日本学術振興会(JSPS)のフェローシップ制度もご確認ください。

Research interests

We are interested in developing powerful statistical tools that utilise the rapidly growing numbers of genomes of modern and ancient humans (or of other species) to reconstruct our shared genetic past.

Our genomes can, for instance, inform us about past migrations, introgression with Neanderthals and other extinct hominids, and adaptation to environmental or lifestyle changes throughout human history. In particular, we are interested in understanding how evolutionary forces have shaped our genetic differences and how these may impact our health.

Keywords: Population Genetics, Evolutionary Biology, Ancestral Recombination Graphs, ancient DNA, population history, human origins, natural selection, mutation rate evolution, bacterial evolution, canid evolution, speciation, introgression
