【EVENT】The 1st School of Science Café 2021 ~Online~

Are you a high school or undergraduate student who has a passion for science? Then join us for the first School of Science Café and learn about exciting and topical research being conducted at the School of Science. At this event, you will also get the rare opportunity to interact with UTokyo professors and ask them your questions about research and student life at the School of Science, all from the comfort of your own home.

This online event will be held entirely in English and is open to students worldwide. We hope to see you there!

Unlocking the secrets of the Universe — by observing tiny, elusive neutrinos
Dr. Yokoyama

Masashi Yokoyama, Professor,
Department of Physics

— About the Speaker —
Masashi Yokoyama is a Professor of Physics in the School of Science, The University of Tokyo. After receiving his Ph.D. from the University of Tokyo, Masashi began to work on experimental neutrino physics at Kyoto University before returning to UTokyo in 2009. He has played key roles in experiments using neutrinos produced by particle accelerators at KEK, J-PARC (both in Japan), and Fermilab (in the U.S.).

What is the world made of? The goal of particle physics is to provide the answer to this profound question. For more than a century, physicists have advanced our understanding of the fundamental building blocks of matter. Neutrinos are among the most abundant and least understood of all elementary particles that make up the Universe, and are thought to hold the keys to unlocking the mysteries of the Universe.

The University of Tokyo has been leading the field of neutrino physics for decades. The Nobel Prize in Physics in 2002 and 2015 were respectively awarded to the discoveries made using Kamiokande and its successor, Super-Kamiokande, both of which are research facilities hosted by the University of Tokyo. The construction of the third generation facility, Hyper-Kamiokande, started in 2020.

In this lecture, I will talk about what we have learned from neutrinos and what we can expect in the future.

Mathematical Modeling Approach to Infectious Diseases
Dr. Ohashi

Jun Ohashi, Associate Professor,
Department of Biological Sciences

— About the Speaker —
Jun Ohashi is an Associate Professor in the Department of Biological Sciences at the School of Science, The University of Tokyo. His research field is human evolutionary genetics. He received his Ph.D. from the Graduate School of Medicine, The University of Tokyo.

Mathematical modeling deals with various phenomena using mathematical equations. In the field of biology, it is very useful for understanding biological phenomena, from the behavior of molecules to the evolution of species. In this lecture, I would like to introduce the SIR (Susceptible Infected Recovered) model of infectious diseases, taking the case of a new type of coronavirus infection (COVID-19) as an example. In the SIR model, the populations of S, I, and R compartments are given as variables of time, and the changes in population size are described using the simultaneous ordinary differential equations.

I hope that, through this lecture, you will not only learn the basic theory of mathematical modeling of infectious disease dynamics, but also discover effective measures against COVID-19 by developing the model.
