About Punreach.

Former Software Developer and currently an MSc Computing Science researcher at the University of Alberta, focusing on Machine Learning, Natural Language Processing, and Speech/Audio Processing. My work explores how AI models can better understand human language and speech, with applications in language learning, speech technology, and intelligent systems.

I am a member of the EdTeKLA Research Group under the supervision of Dr. Carrie Demmans Epp. Before graduate school I spent four years building production software in South Korea — from mobile security SDKs to a computational algebra system.
