Saki YOTSUIColumn☆Self Introduction
Born in Bunkyo-ku, Tokyo. I conduct research on
urban disaster prevention. In this line of work, I
am often asked why I chose my research field,
but in my case, I happened upon this field bychance. When I was a university student, I waswandering around the library and happened tonotice a book titled “Building Fire Prevention”
written by Dr. Saburo Horiuchi. Until then, I had
been interested in “urban analysis,” which uses
mathematical models to explain the form andstructure of cities, but as I read through thebook, I became interested in the usage ofmathematical methods to predict and analyze
disaster phenomena and apply them to disasterprevention measures. If I had bought books on
Amazon back then, I might not have had such achance encounter. About five years later at thevery start of my career, the head of thelaboratory where I was a specially appointed
assistant professor happened to be Dr. AiSekizawa, who had studied in Dr. Horiuchi'slaboratory. I was then given detailed guidanceon Fire Following Earthquakes. Perhaps
because my second hometown is Nagoya,
where I lived for about four years, I am
particularly fond of underground public spaces incities. I also like rice, whiskey soda, and coffee.

The health risk posed by antimicrobial-resistant bacteria (ARB), which is regarded asa silent pandemic, is a global concern. To control ARB, the perspective of One Healththat integrates health of humans, domestic animals, and the environment isimportant. However, the surveillance of the environmental health has not been
established yet. In urban area in developing countries, untreated sewage isdischarged into the environment, leading to the spread of ARB. We analyze diverse
ARB in water environment and sewage by comprehensive and high-throughput
molecular methods to monitor urban public health status and to study the mitigationof ARB risk.

We are conducting a wide variety of research centering on the theme of "urban
disaster risk reduction." What is the goal of the city's "safety" function, and who
evaluates it? And how do we balance that with other urban features such as
convenience and comfortability? Our laboratory is researching the system design andplanning that provide clues to these issues from the perspective of urban andcommunity planning. We use a variety of research methodologies, including fieldsurveys in disaster impacted areas, questionnaire surveys, disaggregate models, OR,
Bayesian statistics, machine learning, simulations, and developing workshop tools.
Our goal is not only for developing models and visualization of risks, but also
implementation in society through the research process such as collecting original
data, constructing our own theories, and disseminating research outputs.
