Hi! I'm Litao Yan


Ph.D. in CIS
University of Pennsylvania
Philadelphia, PA

Hey! I'm Litao Yan, a first-year Ph.D. student advised by Prof. Andrew Head at UPenn. My primary interests lie in the intersection of Human-Computer Interaction (HCI), programming languages, software engineering, and interactive data visualization. I am super excited about designing interactive user interfaces for data-driven decision-making.

I am also working with Prof. Elena Glassman (Harvard), Prof. Tianyi Zhang (Purdue), Prof. Björn Hartmann (UC Berkeley), and Prof. Miryung Kim (UCLA) on the code demography project sponsored by the NSF grant.

I received my M.Eng. in CSE from Harvard University. I also worked as a research assistant with Prof. Glassman.

Visualizing Examples of Deep Neural Networks at Scale

The ExampleNet is an interactive interface to explore various neural network design decisions. I conducted a within-subject study that proves the usefulness of ExampleNet.

VisMeet: Data-Enhanced Video Conferencing

VisMeet presents the interactive visualizations of the implicit online meeting data with the users. The between-subject study I conducted shows the effectiveness of it in building users' awareness of the meeting in a short time.

Exploring the Complexity of COVID-19 Visualizations

I use D3.js to generate a series of COVID-19 visualization with various complexity. We will design a user study to find the difference of calculated complexity and participants' conceptual complexity.
