I'm an undergraduate researcher at UNIST, joining the Ubiquitous AI Lab as an M.S./Ph.D. student this September. I work on efficient AI, lately on making GUI agents cheaper to run.

I'm a computer science senior at UNIST, working on efficient AI.

This September I'm staying on for my M.S./Ph.D. at the Ubiquitous AI Lab with Prof. Taesik Gong, where I've already been doing research as an undergrad since January. The part I like is getting a model to do more without paying for it twice: methods that need no extra training, that drop into a system already running, and that pass work between the device and the cloud when that helps.

Lately that has meant GUI agents. They can operate real software on their own, which is impressive right up until you notice every step is a full model call. I'm writing my first paper on cutting that cost while keeping what the agent can actually do.

A line I keep coming back to: “If you seek death you will live; if you seek life you will die.”

It comes down to one stubborn fact: the models that work best are usually the ones you can least afford to run, and most of that bill lands at inference time.

  • Efficient inference
  • Training-free methods
  • Personalized AI
  • Edge-cloud
  • GUI agents

Efficient AI

Training-free, plug-and-play methods. I would rather find a win you can bolt onto a system that already runs than one that only pays off after another round of training.

Personalized AI

Shaping a model around a particular user or device without retraining it from scratch for each one. In practice it leans on the same efficiency tricks.

One working paper for now. Anything that gets published will show up here.

    Early work on cutting the inference cost of GUI agents. I'll post a preprint here once it holds up.

A few things I've built, in and out of the lab.

  • 2025

    Construction-safety LLM

    Hansol Deco Season 3 AI Competition

    A retrieval-augmented LLM that drafts accident-prevention and response plans for construction sites, built with RAG and a lot of prompt iteration.

  • 2024

    Fine-dust prediction model

    2024 Environmental Data Contest

    A model that estimates particulate-matter levels at a given location from nearby monitoring stations and fugitive-dust data.
