Hiromi M. Yokoyama is a sociologist of science, Professor at the University of Tokyo.
Academic specialty is in the Sociology of Science, STS and SciComm. research on polarization, AI, green AI, medical AI, Big Science, climate engineering, Covid-19, Women in STEM, Crowdfunding, ST&I policy, 3.11, etc.
I became an Science Technology and Society (STS), science policy and Science communication (SC) researcher after Ph.D in particle experimental physics. That is the reason why I belong to Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU). I also belong to Graduate School of Interdisciplinary Information Studies (III), UTokyo and students in my lab styding at the department.

I welcome visiting students and researchers with the aim of conducting collaborative research. There is also a track record of undergraduate summer research internships. Please contact me if you are interested.
Acceptance record: Tsinghua University,Princeton University, Harvard University,Technical University of Munich,National University of Singapore,etc. Please check member page.
Since I became an associate professor at the University of Tokyo when science communication discussion began in Japan around 2007, I have led discussions on social and science communication, higher education, and large-scale science in Japan. I have contributed to various committees more than 100. Additionally, I currently contributes to Japanese academic societies as a university management advisory council member and a director of a technical college.

While there is active discussion about polarization in the West, in China we have confirmed the phenomenon of elitism and populism coexisting within one person./欧米では2極化の議論がさかんですが、中国では1人の中にエリートリズムとポピュリズムが共存する現象が確認されました。
Digital media has a major impact on trust in science. This special issue, for which I served as guest editor for JCOM, was adopted as a panel at the PCST2025 Aberdeen conference./ デジタルメディアは科学の信頼に大きな影響を与えます。JCOMのゲストエディターを務めたこの特集は、PCST2025アバディーンの会議でパネルとして採択されました。
We are collaborating ELSI research on face recognition, mainly at the Technical University of Munich. /ミュンヘン工科大学を中心に、顔認証についてのELSI研究を行っています。

What is interesting is that through crowdfunding research, the paper proposes a "Budget-funding Community" in contrast to the Journal Community, which is important in scientific theory.We propose that science crowdfunding can be successfully used to generate “crowd-supported science” by means of this Crowd Community./クラウドファンディング研究を通じて、科学論で重視する Journal Communityに対して、”Budget-funding Community”を提案したところに面白さがあります。さらに、科学クラウドファンディングをうまく活用した「クラウド支援型科学」があることを明らかにしました。
