About Me

Hi! I'm an undergraduate student at Seoul National University, majoring in Linguistics, Psychology, and Computer Science.

I aim to develop computational frameworks that extract latent signatures from human brain and behavior, and translate them into practical systems that can:

• Support early and reliable diagnosis of mental and cognitive states,
• Personalize interventions based on individual brain–behavior profiles,
• Improve artificial intelligence by incorporating principles of human learning and adaptation,
• Uncover shared and distinct features across brains, machines, languages, and the systems that structure human life.

Distortion of cortical hue geometry in color vision deficiency enables individualized color correction filters

Apr 2025 – Present

Project Lead (Advisor: Prof. Jiook Cha)

• Characterized individual-specific distortions of cortical hue geometry in color vision deficiency from fMRI, and translated them into personalized color-correction filters.
• Funded by SNU Undergraduate Research Grant ($3,500).

Conferences

• Kim, Jinil, Cho, A. M., Seo, J., Cha, J. (Jul 2026). Inferring Individualized Color-Vision Distortions from fMRI Hue-Representation Geometry. Poster accepted for presentation at the 2026 International Conference on Machine Learning (ICML) Workshop on Structured Data for Health.
• Kim, Jinil, Cho, A. M., Seo, J., Cha, J. (Jun 2026). fMRI Decoding Reveals Intact Neural Color Representations in Color Vision Deficiency. Poster accepted for presentation at the 2026 Organization for Human Brain Mapping (OHBM) Annual Meeting.

Modeling Naturalistic Human Decision-Making with Bounded-Foresight Inverse Reinforcement Learning

Sep 2025 – Present

Research Analyst (Advisor: Prof. Woo-Young Ahn)

• Extending adversarial IRL with a state-dependent planning-depth latent to better imitate human decision-making, while recovering interpretable planning depth from behavior alone.

When, not just how strongly: depression delays the onset of second-attribute integration in social decision-making

Jun 2025 – Present

Project Lead (Advisor: Prof. Yuan-Wei Yao)

• Built a time-varying Drift Diffusion Model (tDDM) with a per-attribute onset parameter (τ) to capture when depression delays integration of the second decision attribute in social decisions.

Presentations

• Kim, Jinil, Yao, Y. W. (Aug 2025). Why Do Depressed Individuals Punish?: A Computational Investigation of Emotion Learning and Bias in Maladaptive Social Behavior. Poster presented at the Summer Research Program Poster Session, University of Hong Kong.
