Undergraduate Research Intern @ Yonsei University / Senior Student @ Yonsei University

Research Intern in AI Graduate School

I am Jinha Choi, working as a research intern at DILLAB (Yonsei Univ) advised by Prof. Jongmin Lee. My current research focuses on action constrained imitation learning, where the agent learns from dataset with less or no action constraints. I aim to expand the topic to work on online reinforcement learning and robot learning.

I previously worked on humanoid loco-manipulation and generalizable humanoid at RLLAB (Yonsei Univ) advised by Prof. Youngwoon Lee.

Honor Roll

Awarded in recognition of commendable academic achievement.

1st Place, Yonsei–Nexon RC Creative Platform

Won 1st place in a university-wide social-impact startup ideation competition co-hosted with Nexon. Led a 5-member team to design an automated revolving-door assistance system to improve safe building access for people with mobility impairments. Developed a 3D-printed prototype and presented the design rationale (safety, practicality, community impact) to judges and organizers; ranked 1st of 90 teams and awarded $10K.

Finalist, VEX Robotics World Championship

Competed at the VEX Robotics World Championship (approximately 600 qualifying teams). Ranked as a Science Division finalist (top finish within a 100-team division), advancing to the division final and narrowly missing qualification to the round-robin finals against the top teams from other divisions.

1st Place, VEX Robotics Canada BC Provincial Championship

Led Team 1010B to qualify for Provincials via a regional championship, then won 1st place in British Columbia Provincials, earning qualification to the VEX Robotics World Championship.
