It is our great pleasure to inform you that 15th Young Scientist Award (Japanese Society for Mathematical Biology) was awarded to our iTHEMS colleagues, Ryosuke Iritani for his contribution to the theory of evolutionary ecology and Takashi for his contribution to the theory of chemical reaction networks. Many congratulations to Ryosuke and Takashi !!

Dr. Shingo Gibo received the Best Poster Award of the Japanese Society of Chronobiology. The title of the poster is "Analysis of the circadian period and phase synchronization based on waveform". Congratulations!

This is an abstract of the awards:
The circadian clocks are based on gene-activity rhythms with approximately 24-hour period, and its temporal waveforms are of various shapes. We theoretically showed that the waveform distortion contributes to the circadian period stability to temperature and entrainment to the environment cycles. Furthermore, by using the renormalization group method, which is developed in theoretical physics, we found that this relation between waveform and period holds not only for the circadian clock but also for many types of nonlinear oscillator models, including van der Pol and Lotka-Volterra model. This study is collaborated with physicists, Drs. Teiji Kunihiro (Kyoto University) and Tetsuo Hatsuda (iTHEMS).

Hello. I am Genki Ouchi, a special postdoctoral researcher in iTHEMS. I am leaving iTHEMS and moving to graduate school of mathematics, Nagoya university as an assistant professor.

I joined iTHEMS on April 2018. Since then, it has been two and a half years. I learned a lot of things from iTHEMS. Before I came to iTHEMS, I was just an “algebraic geometer”. I studied only algebraic geometry and related topics. After joining iTHEMS, I got opportunities to learn other topics in mathematical science. Especially, I study network science with mathematicians, physicists and network scientists now. With an experience at iTHEMS, I become a “mathematician”. I wish that interdisciplinary activities in iTHEMS bear fruit over the long run.

I would like to thank all iTHEMS members for your kind support and help. I am looking forward to seeing you again.

Hello. I am Kenta Sato, a Special Postdoctral Resercher at iTHEMS. I am moving to Kyusyu University as an assistant professor. It is a great pleasure for me to spend one and a half years at iTHEMS because I have been stimulated by the open atmosphere of iTHEMS and by the energetic activities of each member. It helps me to broaden my perspective. I would like to say thanks to everyone in iTHEMS. I am looking forward to seeing the successful development of iTHEMS in the future.

Bonjour! I was already a member of iTHEMS as a Senior Visiting Scientist so probably you already know me. But since September 2020, I became a Deputy Program Director of iTHEMS. I was looking forward to spending more time at RIKEN, working more closely with everyone, but unfortunately, with COVID-19, for now I have to stay in Toronto. As you maybe know, I am a professor of physics, but my research is in the field of virophysics (ヴイルス物理学). I apply the techniques of physics to virology. More generally, I like applying the methods of physics and computational methods to fields where theoretical/quantitative analysis is less common, like biology and health research, or even ergonomics! I think the methodologies developed in physics can translate to many other fields and provide new insights. Most of my work involves/requires direct collaborations with experimental virologists. I also really enjoy convincing other physicists and mathematicians to join in solving these types of problems across disciplines. For me, iTHEMS is an ideal environment to develop such collaborative projects.

In my new role as Deputy Program Director, I want to do my best to help support the young researchers in iTHEMS, and make sure they have everything they need to succeed at their goals. I want to help foster new collaborations, through which everyone can learn new skills, or get help to bring their research to the next level. I have a few ideas that I want to share with all of you over time. If you have some thoughts or concerns, or if you want to discuss something with me, please send me an email anytime. I am happy to get to know you better.

I am Ken Furukawa. My research area is the mathematical theory of partial differential equations related to the fluid dynamics and diffusion phenomena. More specifically, we studied mathematically rigorous justification of the derivation of the primitive equations by the Navier-Stokes equations. The primitive equations have nice properties on well-posedness and have a strong connection with the Navier-Stokes equations. We obtained some results on the well-posedness of the Navier-Stokes equations in this research.

Recently, I have been interested in the mathematical aspect of data assimilation. Data assimilation is very useful to obtain a plausible forecast and is also closely related to our lives. However, mathematically rigorous studies of data assimilation from the mathematical theory of PDE are under development. I will study data assimilation from the view PDE point of view.
