I am a senior applied scientist at Amazon AGI. You can just call me JK.
My current major research interests are conversational AI with large language models, efficient post-training, LLM evaluation, agentic RAG, language grounding, and multi-hop reasoning.
At Amazon AGI, I have been designing and building machine learning models and systems specifically for improving Alexa's core AI components such as mixed-initiative coversational interaction, clarification/disambiguation, dynamic hypothesis routing, and personalized name-free interaction.
I received my PhD degree advised by Eric Fosler-Lussier in the Department of Computer Science and Engineering at The Ohio State University.
During my PhD, I did three research internships on deep learning for conversational understanding at Microsoft in summer 2016, deep & recursive neural networks for constituency parsing at NEC Laboratories America in summer 2015, and deep & recurrent neural networks for named entity recognition at Nuance Sunnyvale in summer 2014.
Between 2012 and 2014, I worked on hierarchical compositions of acoustic features and multiple target labels from various languages with deep neural networks for IARPA's Babel Program.
I received my MS degree advised by Byoung-Tak Zhang from Seoul National University and my BE degree from Sogang University.
Before OSU, I worked at Naver for two years as a software engineer (manager) developing Internet search services. Also as alternative military services, I developed mobile games at ZIO Interactive and financial risk management software at IBK System.
