On 6 October 2019, I wrote an op-ed for Seoul National University’s official newspaper on the need to pursue “internationalization from below” and life of third culture kids on campus. The piece included a discussion of my experience co-organizing a special orientation event for international students in the College of Liberal Studies called 36.5.
“.5” is an informal term for students who begin their university life in September because the Korean academic year typically starts in March. “36.5” expresses our effort to emphasize equality with a reference to the average human body temperature.

On 7 November 2016, I appeared on an episode of the DH East Asia podcast. I was interviewed by Dr. Amanda Shuman at the University of Freiburg. We discussed the uses of network visualization tools such as Gephi and Cytoscape in historical research and the state of the digital humanities in South Korea.

On 2 December 2014, I appeared as a guest on the Hong Kong public radio station RTHK in the program “Free as the Wind” (講東講西) hosted by Shum Yat-Fei. I discussed common questions and myths about Korea and Korean culture and responded to questions from the audience.
