Self-introduction: Ade Irma Suriajaya
Hello! My name is Ade Irma Suriajaya but people usually call me simply Chacha. I am originally from Indonesia and I made the nickname from my Chinese name, another name I have which is not officially registered, except in my college documents. I went to Nanjing University of Aeronautics and Astronautics in China after graduating from high school in Indonesia to pursue undergraduate study in Aeronautical Engineering. I was attracted to Mathematics in just my first month, thanks to the very interesting Calculus class I had back then. I got my first opportunity to study pure mathematics two years later when I got a scholarship for a one-year academic exchange program in Nagoya University in Japan. However I could not do that without sufficient Japanese proficiency, but I was finally able to take basic pure mathematics courses (designed for third semester students) the next semester, and I made up my mind to change my major to Mathematics. Nevertheless, there was no pure mathematics major in my home university in China and during the last year of my undergraduate study, I was taking only mathematics classes offered by the applied mathematics major (the official name was not Applied Mathematics). I managed to come back to Japan the year after, soon after I got my bachelor degree to finally, officially start my path in mathematics. This year marks the seventh year I work in analytic number theory. My main research interest is the analytic properties of zeta functions and L-functions such as, location of zeros and distribution of values of these special functions. I am very delighted to be a part of iTHEMS where I get to easily communicate with other theoretical scientists. I used to be more into Physics and Chemistry when I was in middle school and high school and I am very happy to get to know lots of new things, not only in those fields, but also in other fields of science. Furthermore, I am mostly excited to be able to collaborate with other scientists and hopefully apply my (still very very limited) knowledge in mathematics and also probably, the more limited knowledge in engineering or applied mathematics.

Self-introduction: Tomoki Ozawa
I am Tomoki Ozawa, a senior research scientist at iTHEMS. I am originally from Japan. I finished my PhD in the University of Illinois at Urbana-Champaign in the US, and then spent five years as a postdoc at the BEC Center (Bose-Einstein Condensation Center) at the University of Trento in Italy. Then, after spending three months in Brussels, Belgium, I came back to Japan and joined RIKEN iTHEMS this April. My main research interest is in the intersection between condensed matter theory and AMO (Atomic, Molecuar and Optics) theory. In particular, I have been working on many-body and topological physics of ultracold atomic gases and photonics. My style of research is to try to understand target systems in as simple way as possible; this sounds rather trivial, but it often leads to something unexpected in the end. In iTHEMS, I hope to collaborate with people from various backgrounds and start something exciting together.

Self-introduction: Masaru Hongo
I am Masaru Hongo, a theoretical physicist working on nonequilibrium physics. My main interest is hydrodynamics and its possible generalizations to more general nonequilibrium systems. Hydrodynamics universally describes a lot of phenomena seen in the world. Its application covers not only simple liquids in our daily life, but also the extremely high temperature plasma (the so-called quark-gluon plasma which reaches at several trillion Kelvin). Since our fluid is composed of atoms/molecules, or extremely elementary particles described by quantum theory, it is interesting to consider how we can understand the gap between two descriptions. I have studied to bridge this gap between hydrodynamics, which gives a macroscopic description of systems, and quantum field theories, which is a fundamental microscopic theory considered to be state-of-the-art atomism. Based on the recent development of non-equilibrium statistical mechanics, I have provided a solid basis for relativistic hydrodynamics. I am now working on how we can describe the more general nonequilibrium systems. I am happy if we are interacting with each other, and have fruitful collaborations!

Self-introduction: Takashi Okada
I am Takashi Okada. I am a senior research scientist of iTHEMS from this spring. Previously, I was a postdoc researcher of Mochizuki Theoretical Biology Laboratory (April 2014 to March 2018). My original background is theoretical physics, and, before I came to Mochizuki Laboratory, I researched on particle physics and super string theory. Now, my main research subject is theoretical biology, and, especially, I am interested in biological networks, such as gene regulatory networks, metabolic networks, and signal transduction networks. I would like to understand how today’s biological networks arise through evolutionary processes. I think that iTHEMS is the best environment to study theoretical biology because life science is a very broad field that involves mathematics, physics, chemistry, statistics, and so on. I would like to learn a lot through interaction with iTHEMS members. Also, I am very happy if we can collaborate with each other.

Self-introduction: Yoshiyuki Inoue
Hello everyone. My name is Yoshiyuki Inoue. I am a senior research scientist at iTHEMS/RIKEN. Previously, I was a JSPS fellow at KIPAC/SLAC/Stanford, and then an International Top Young Fellow at ISAS/JAXA. My research is theoretical astrophysics which is closely connected to observations. I am interested in understanding the nature of supermassive black holes. Here at iTHEMS, I would like to link theory and observations more tightly. I am also hoping to broaden my research fields through interdisciplinary interactions at iTHEMS.
