Hi! I am Ruoyu Li (李若愚 Lǐ, RuòYú), an advocate for the dark sky movement and responsible outdoor lighting. I have experience working in startups and NGOs, and am currently a graduate student in urban data science at NYU CUSP (Center for Urban Science + Progress). I'm an Engagement Volunteer at DarkSky International, and I lead the DarkSky Beijing and DarkSky New York chapters. I'm also a member of the Student Committee and the Open Tech Committee at GISMO (NYC GeoSpatial Information Systems and Mapping Organization). I am passionate about using data to drive urban sustainability and improve community engagement.

I graduated from the University of Arizona with a B.S. in Mathematics, a B.S. in Information Science, minors in Statistics and Data Science, Computer Science, and Finance, and a certificate in Entrepreneurship and New Venture Development. I also received a Graduate Certificate in Advanced Business from Columbia University and the Credential of Readiness (CORe) from Harvard Business School Online.

In my free time, I enjoy photography, astronomy, and spending time with my two lovely cats. I also love exploring new technologies and their applications in urban environments.
