About me

I'm currently a Data Scientist at Paran Energy and a National Researcher under SK Telecom Consortium funded by the South Korean Ministry of Trade, Industry and Energy.

I'm also an undergraduate student at the University of Toronto studying Mathematics and Physics with a minor in Statistics.

At Paran Energy, I have been working on machine learning and deep learning-based models for non-intrusive load monitoring (NILM), electricity trading, and demand response advised by Dr. Seong-cheol Kim.

I have been very fortunate to work with brilliant mentors/co-workers and gain lots of hands-on experience.

Research

My research interests lie on the application of machine learning to sequential data.
e.g. time-series analysis, signal processing, audio processing, and natural language processing.

IEEE Access, 2021

We propose a method to indirectly calculate the incentive for each customer not using the customer’s data but using the data of other customers of the same DR group (cluster). Our method solves the non-equal incentive problem in most cases.
