Nguyen Thuy Ngoc

Hi, I’m currently a postdoc at the Dynamic Decision Making Lab (DDMLab) at Department of Social and Decision Sciences at Carnegie Mellon University. Prior to CMU, I received my PhD for research on supporting group decision making process with recommendation techniques at the Faculty of Computer Science at the Free University of Bozen-Bolzano, Italy. Previously, I completed my master’s and bachelor’s degrees at Vietnam National University - HoChiMinh City University of Science and HoChiMinh City University of Education, respectively.
My full first name is Thuy Ngoc, which I use for official documents and publications. In all other situations, such as email exchange or day-to-day communications, I simply go by the shorter version, Ngoc.
Research Interests: Recommender Systems, Modeling of Human Behavior, Artificial Intelligence, Human-Computer Interaction, and Machine Learning

A chat-based group recommender system The application domain of this project is point of interests (POIs) recommendations for a group of people. It is a working prototype of group recommender system, an Android mobile application.
Simulation models for group decision making process Simulation experiments to analyze and gain deeper insights into the interplay between group members’ behavior and the performance of group recommendations.
Visualization of humans playing a search and rescue mission in Minecraft Collecting data from human participants and visualize it on the map. [Code]
2D Minimap game Interactive minimap game of search and resue mission. [Code]
