2nd iTHES meeting

To enhance mutual interactions in iTHES, we organize the "iTHES Meeting" every 2 months or so. The first meeting was held in Oct.15,2013. As shown below in the Upcoming Events, we will have the 2nd meeting on Jan.31 (13:30-14:30) just before the iTHES Colloquium. This time, three iTHES researchers, Dr. K. Uriu (ithes-bio team), Dr. T. Iitaka (ithes-cond team) and Dr. T. Kanazawa (ithes-phys team), give short presentations to introduce themselves. We urge all the iTHES members to attend this 2nd iTHES meeting to get to know each other.

  • Event Report

    Wako-AICS joint symposium on "K, Post-K, and fundamental physics" was held in RIKEN Wako Campus on January 7th, 2014. RIKEN is operating the K computer at Advanced Institute for Computational Science (AICS). AICS also plays a central role in developments of post-K supercomputers. There were about 25 participants to discuss current situation and design of the post-K projects and possible applications in a variety of fields, from hadron/nuclear/astrophyscs to meteorology. The photo shows Dr S. Nagataki, iTHES-phys team Research Associate, presenting his current and future efforts in numerical studies on supernovae and gamma-ray bursts. The present symposium will stimulate communication and collaboration among researchers in AICS and Wako area.

    Person of the Week

    Koichiro Uriu
    I am Koichiro Uriu and a member of the Interdisciplinary Theoretical Biology Team. My main interest is on the theoretical modeling of embryonic development. Currently, I am focusing on the effect of cell movement on information flow in developing tissues. My collaborators and I have been developing physical models to study this topic, which include a population of phase oscillators on a lattice similar to the XY model, and their random motions on the lattice. We analyze how the mobility of these oscillators changes dynamics toward synchronization which can be regarded as an outcome of information flow across the oscillators. The model was motivated by vertebrate somitogenesis during embryonic development where the synchronization of cell-autonomous oscillators by local cell-cell interactions plays crucial roles in making a segmented body plan.
    I think that interdisciplinary approach would be a key to understanding development, because it occurs as interplays between both biological and physical aspects, and to analyze them we need biological experiments, data analysis including image processing and statistical inference, and physical modeling.
    I did my undergraduate study in the department of Biology at Niigata University in Japan. Then, I did my Master and Ph.D studies in the Mathematical Biology Laboratory at Kyushu University where I learned how to model Biological phenomena. After I got Ph.D, I was a visiting researcher of the Max Planck Institute of Molecular Cell Biology and Genetics (Dresden, Germany) where I studied synchronization of locally coupled mobile oscillators with both theory and experiments. In Dresden, I had opportunities to collaborate with experimental biologists and statistical physicists. Making use of these experiences, I would like to enjoy the collaborations with other iTHES members here.
