• We try to understand the neural correlates involved in high-level cognition in humans, emphasizing the function of the prefrontal cortex in relation to other areas in the brain.

• Particularly, we are interested in how people deal with complex sequences of inputs in everyday lives using cognitive control, in other words, complex sequence processing. This is related to various cognitive processes such as achieving goals, making inferences, grasping regularities, and making predictions and time perception.

• Brain big-data analysis is also one of our research topics, establishing cognitive models for functional as well as structural networks in the brain out of neuroimaging data.

• We also investigate how executive functions influence on human language processing in the aspects of semantics, syntax, and pragmatics.


• We employ various cognitive neuroscience methods including functional & diffusion magnetic resonance imaging (fMRI & dMRI), resting-state fMRI, transcranial magnetic stimulation (TMS), computational modeling, psychophysics (behavioral testing), and neuropsychological assessment (testing of patient populations).

• Using these methods, we unravel functional and structural networks involved in the high-level cognition in the human brain and establish computational models to increase our understanding of optimized cognitive processes in humans.

Hee Dong Yoon graduated from Brandeis University, Waltham, Massachusetts in 2016 with a bachelor’s degree in psychology and HSSP (Health, Science, Society, and Policy). During his years at Brandeis, Hee Dong was interested in neuropsychological bases of perception and neurodegenerative disorders. At DGIST, he is mainly studying the mechanism behind figurative language comprehension, especially metaphors.

Yoo, Taehyun (Doctoral student)

Taehyun graduated from DGIST in 2018 with a bachelor's degree in convergence science. He used to be a "super-talented" intern in the Jeon Lab in 2017 and finally became a lab member in March 2018. He is so much interested in the processing of hierarchical structure using multi-sensory information.  

Park, Jungtak (Doctoral student)

Jungtak graduated from DGIST in 2018 with a bachelor's degree in convergence science. He was one of the "super-interns ;)," and now he is ready to become a "super-researcher" focusing on functional connectivity in learning sequences.

Shin, Minho (Master's student) 

A smart student with full of curiosity. He has been working on a meta-analysis on the reasoning process using a computationally-efficient generative model.
