If you are trying to enroll in COGS1001 but the class is full, please read this before emailing me or Dr. Yang!
If you are a COGS major/minor or a student in COGS1001 trying to meet with me, and my office hours below do not work for you (please try these first!), you can find a time to meet with me here.
If you need to correspond with me about COGS adivisng (e.g., majoring/minoring in COGS), please use email@example.com rather than my personal or Penn emails.

I am the Associate Director of Cognitive Science and MindCORE at the University of Pennsylvania. Previously (2021-2022), I was a a data scientist in the Tsui Lab at the Children's Hospital of Philadelphia. Before that, (2018-2021) I was a post-doc with Sudeep Bhatia in the Computational Behavioral Science Lab of the Department of Psychology at the University of Pennsylvania. In 2017, I received my PhD in Developmental Psychology at the University of Connecticut. There I primarily worked in the Language Creation Lab under the mentorship of Marie Coppola, and in the SoLab under Whit Tabor. I was also a fellow in the Language Plasticity -- Genes, Brain, Cognition, & Computation IGERT (which is now the Neurobiology of Language program), and an affiliate of the CT Institute for the Brain and Cognitive Sciences.
My interests and work have changed a lot over the years, but the common thread is using data science, machine learning, and natural language processing tools for social, cognitive, behavioral, and biomedical problems. See my papers below for more!
