Resume (English only)
Education
  • First-year PhD student in the Cognition and Neural Systems Program at the University of Arizona, advised by Robert Wilson.
  • Prior to PhD, worked with Xue-Xin Wei at UT Austin.
  • Earlier collaborated with Da-Hui Wang at Beijing Normal University.
  • Previously used EEG to study working memory.
  • Studied counseling psychology with a focus on cognitive behavioral therapy during undergraduate studies.
Background
  • Studies computational neuroscience.
  • Interested in understanding large language models (LLMs) beyond mechanistic details, exploring how LLMs can enhance collective decision-making and inform policy, aligning LLMs with human priors and ultimate good values, and using mechanistic insights from LLMs and neural network theory to expand the space of cognitive hypotheses.
  • Uses models to understand behaviors of both biological and artificial agents and explores how computation could be implemented in neural networks.
  • Since the release of GPT-4, research focus has partially shifted toward understanding the emergence of intelligence in large language models.
  • Current research interests include: using recurrent neural networks as cognitive models to identify hidden variables in cross-species decision-making; examining how prior information is encoded in working memory via optimization-based neural network models; and investigating how humans use language as a tool for control and agency through dialogue.
Miscellany
  • Addicted to exploring complex ideas and writes controversial thoughts on his blog.
  • Enjoyed reading as a youth; favorite authors include James Joyce, Milan Kundera, Jorge Borges, Franz Kafka, Dostoyevsky, and Edgar Allan Poe.
  • Lost patience for long books after high school.
  • Addicted to computer games, but only when exams are approaching—now rarely plays due to few exams.
  • Enjoys skiing, dark humor, and embarrassing short videos.
  • Finds using a second language painful, especially because he struggles to express sarcasm well in English.
  • Bad at arithmetic—even messes up single-digit calculations with pen and paper, which makes him doubt his suitability as a computational neuroscientist (though notes that LLMs also fail at simple math).
