I’m a tenure-track Assistant Professor at the Department of Computer Science and Engineering at the Hong Kong University of Science and Technology. Previously, I was an NIH K99/R00 Pathway to Independence Fellow at the Department of Biomedical Informatics at Harvard Medical School, working with Nils Gehlenborg. I received my 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, I work at the intersection of visualization, human–AI interaction, and biomedicine. Current focus areas include ➊ visualization and human–AI interaction for biomedical applications (e.g., healthcare, science, and education), ➋ toolkits and infrastructure for scalable visualization and human–AI interaction, ➌ AI interpretability and model understanding through interactive visualization, and ➍ emerging interaction techniques for complex biomedical data (e.g., VR/AR/MR). For example, I led the design and development of the Gosling visualization grammar, which enables constructing scalable and interactive genomics data visualizations and leveraging AI methods (read Nature’s Technology Feature).
My work has been published in top-tier conferences and journals across my fields, including VIS, TVCG, CHI, UIST, Nature Methods, Bioinformatics, and npj Digital Medicine. I have received several academic awards, including the NIH/NHGRI K99/R00 Pathway to Independence Award, VIS Best Paper Honorable Mention Award, ISMB BioVis Best Abstract Award, ISMB BioVis Runner-Up Abstract Award, and VIS Best Poster Research Award. I have served on the program committee for top visualization conferences, including VIS, EuroVis, and PacificVis.
I'm currently looking to recruit PhD students (Fall'26, Spring'27, Fall'27) at HKUST CSE. For details, please read the Work With Me page.

Nature (TECHNOLOGY FEATURE)
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."
