I’m a postdoctoral research fellow advised by Nils Gehlenborg at the Department of Biomedical Informatics at Harvard Medical School. I am also the DEI committee of the Department of Biomedical Informatics and an accessibility ambassador at Harvard through Whole Me Campaign. I received my PhD in Computer Science and Engineering from Seoul National University where I studied Human–Computer Interaction and Visualization under the supervision of Jinwook Seo at the HCI Lab.

As a researcher working at the intersection of human–computer interaction, visualization, and biomedical informatics, I design, develop, and evaluate visualization techniques and tools to help a broad range of people in genomics to access, analyze, and communicate genomics data. In the HIDIVE Lab, I have been focusing on the Gosling grammar-based genomics data visualization, which enables the flexibility in creating interactive genome-mapped data visualization. As a part of my research contribution in biomedical informatics, I have been also contributing to several projects with large data portals, including Consortium for Clinical Characterization of COVID-19 by EHR (4CE), Cistrome Data Browser, and cBioPortal, such as integrating interactive data visualization.

I am in the job market starting this year (2024-2025 cycle) looking for tenure-track faculty positions in Computer Science, Computational Biology, Bioinformatics, and related fields. Please reach out to me if you have any questions or opportunities! (sehi_lyi@hms.harvard.edu)

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."
