Hi, I'm Raina! I am an National Library of Medicine (NLM) Postdoctoral Fellow in Biomedical Informatics and Medical Education at the University of Washington. I received my Ph.D. and M.S. in Human Centered Design & Engineering at the University of Washington in 2023, where I designed and evaluated conversational user interfaces for healthcare applications. My research interests include human-computer interaction (HCI), conversational user interface (CUI) design, machine learning, and health informatics.
I am passionate about working with people to design and build more usable and equitable technology. As a HCI researcher, I enjoy applying quantitative and qualitative methods to improve users' experiences and shape the design of emerging technologies.
Previously, I received my bachelor's degrees in Computer Science and Studio Arts from the University of Rochester. I have conducted research at Snap, Meta, and the ROC HCI Lab.
My work is published in venues including CHI, CUI, and IMWUT, and has received awards at top conferences in human-computer interaction, including Best Paper and Honorable Mention Awards at CHI and CUI.
