What do you specialize in? My specialty is micrometeorology. This discipline examines phenomena that occur in the atmosphere near the surface of the earth, up to about 1000 meters. In recent years, scientists are trying to clarify how greenhouse gases such as carbon dioxide and methane, which are thought to cause global warming, are exchanged between the atmosphere and the surface of the earth. And this exchange is greatly affected by the atmospheric conditions near the ground surface such as temperature and wind. I use my knowledge of micrometeorology to measure this greenhouse gas exchange on various surfaces. Currently, I am conducting research in the boreal forests of Alaska, Lake Suwa, and the alpine ecosystem of the Central Alps in Japan. Why did you become a researcher? It's hard to explain the specific reason, but I took a year off during my master's program and spent time as a trainee at the University of Edinburgh. During this time, I was able to participate in observation programs in Scotland and the Brazilian rainforest. I discovered the joy of research during this time. Of course, the work of a researcher is not fun all of the time. However, having enjoyed researching during the gap year influenced me to decide to proceed to my PhD program and to become a researcher.
Could you give us examples of some moments you enjoy as a researcher? I carry out automatic observations in the field, and I am always looking forward to checking the collected data and seeing what kind of phenomenon is occurring there. It is very interesting to infer the natural phenomena occurring in the field from the changes in the numbers of the obtained data. We often make hypotheses and analyze data during research, and the moment when the hypothesis is proved by data analysis and research papers written based on it is accepted, I feel our efforts have been exonerated. Do you have goals you are currently working towards? My current research theme is methane emissions from lakes. The current goal is to produce important research results on this subject. Methane emissions from lakes are complicated by processes such as methane production and consumption by microorganisms, factors that affect them, and lake water mixing. We aim to clarify such effects and to be able to predict future changes in methane emissions from lakes. Another goal I have, although it is not a specific goal, is to continue daily research and accumulate such research. I would like to continue to constantly publish my research results as papers. Could you tell us about three items such as work tools or books? One of my favorite items is the observation sensor. Here are some photos of them in the field.
This is Suwa Lake.
And the rest are at observation sites in the Central Alps.
A reference book I enjoy. Although it is not necessarily new, it is an undisputed classic.
This is a map of Alaska, which is one of my favorite fields. I work out of Fairbanks mostly.
