Younghan Park
I study Natural Language Processing (NLP), focusing on both written and spoken language. I got my BS in CSE from Yonsei University, where I had a fortune to be advised by Prof. Youngjae Yu. Also, I spent my junior year at The University of Texas at Austin, where I was fortunate to be advised by Prof. Eunsol Choi and Prof. David Harwath.
My long-term goal is to build machines that can perceive, understand, and use language in a human-like way. My current areas of interest are:
- Multimodal Language Understanding: How can we teach machines to understand the information that arises from the fusion of text and other modalities? What if the context is complex, long, or unstructured?
- Natural Speech Generation: How should non-textual information, such as contextual and prosodic cues, be modeled and processed when generating human-like responses?
๐ I was recently selected as a recipient of the Korean Government Scholarship Program for Study Overseas. With this great opportunity, I will be applying to MS programs in the US for the Fall 2026 semester!
