I’m a postdoctoral researcher at Harvard University working with Nils Gehlenborg. I received PhD in Computer Science and Engineering from Seoul National University with the supervision of Jinwook Seo at the Human-Computer Interaction Lab.
As an interdisciplinary researcher working at the intersection of data visualization, human-computer interaction, and biomedical informatics, I design and develop versatile visualization tools that scale to a wide range of user needs within the biomedical domain. Focusing on genomics, I introduced a novel domain-specific language (DSL) for constructing scalable and interactive genomics data visualization (read Nature’s Technology Feature). It not only empowers domain experts to create custom visualizations and tools that are tailored for their needs, but also enbles scientists to leverage AI techniques given that the formal grammar is machine-interpretable.
I have also been closely collaborating with diverse biomedical experts through my expertise in visualization and biomedical informatics. A collaborative project focused on analyzing and visualizing electronic health records (EHR) data of COVID-19 (4CE Consortium).
Research I led received several major academic awards, including NIH/NHGRI K99/R00 Pathway to Independence Award, Best Paper Honorable Mention (Top 5%) at IEEE VIS 2024, and Best Abstract Award (Top 1) at ISMB BioVis 2021.

Powerful 'grammar' allows geneticists to display their data in interactive and scalable illustrations.
"Postdoc Sehi L’Yi, who led Gosling’s development, says that what differentiates Gosling from other visualization tools is its expressiveness. With most tools, he says, the graphics that can be made and what they will look like are predefined. ‘It is really not easy to customize visualizations as a user.’ But with Gosling, users can, for instance, specify the colour, dimensions and placement of the symbol used to represent a centromere or genomic interval, then overlay that on an ideogram of a chromosome to highlight a region of interest."
