Mason Liu

Researcher, athlete, builder

I grew up in Beijing and moved to the United States during high school to train at IMG Academy. Over the past decade, my journey has taken me across science, sport, and technology, shaping a mindset focused on building things that create meaningful impact.

I am currently a PhD candidate in Geography and Environmental Engineering at Johns Hopkins University. My research focuses on Arctic methane emissions and climate change, using aircraft observations, atmospheric transport models, and Bayesian inverse modeling to better understand greenhouse gas emissions across high-latitude ecosystems.

Prior to my PhD, I earned a Master of Health Science from the Johns Hopkins Bloomberg School of Public Health and a Bachelor's degree in Business Analytics from George Washington University.

Alongside academics, tennis has been a central part of my life. I competed in NCAA college tennis and reached a national singles ranking of No. 23. Today, I continue to stay involved in the sport as a coach, working with competitive players at the collegiate and professional levels, including athletes competing on the ATP tour.

Beyond research and coaching, I enjoy building things. I develop iOS applications, create bilingual educational content, and explore how artificial intelligence and technology can help people better understand human motion, improve athletic performance, and learn more effectively.


Where my time goes

Research

Climate science, methane modeling, atmospheric remote sensing. First-author publications and NASA-funded projects aimed at understanding how greenhouse gases move through the atmosphere.

AI & Entrepreneurship

Building products at the intersection of AI, human performance, and everyday life — iOS apps, educational media, and open-source tools that turn research ideas into things people can actually use.

Tennis & Athlete Development

Coaching players from college to the ATP tour. Thinking about how data, technology, and intentional practice can help athletes compete at the highest levels.

Education & Mentorship

Creating content and communities that help students and young professionals find their own path — across languages, disciplines, and borders.
