About


I am a PhD student in Electrical and Computer Engineering at Rice University, advised by Prof. Richard Baraniuk. Previously, I obtained M.S and B.S in Electrical and Computer Engineering at Rice University in 2020 and 2016, respectively. I have been a research intern at Google AI (2022), NVIDIA Research (2022), and Microsoft Research Cambridge (2019).

My research focuses on machine intelligence for human intelligence. Specifically, I develop machine learning and natural language processing methods with applications in large-scale, personalized learning in education. My goal is to develop novel Intelligent systems to transform the largely static, one-size-fit-all learning practices and enable new opportunities for more effective, personalized human learning. I am currently focusing on the following two directions:

  1. Representation and generation methods to enable adaptive learning content (e.g., assessment quiz questions) that personalizes to each learner
  2. Algorithms and frameworks for modeling human (e.g., learners and instructors) behaviors and preferences in large-scale learning scenarios

At the same time, I am also broadly interested in natural language processing, generative modeling, and representation learning.
