Sarah F.

- Team Leader

Sarah is a second-year Ph.D. student in Computer Science in the Intelligent Information Access Lab at Emory University. Her research interests are in natural language processing, especially in the context of conversational systems, information retrieval, and information extraction. During her first year at Emory, Sarah worked on improving the capabilities of conversational search systems through the incorporation of engagement detection. Before coming to Emory, her research efforts focused on developing automated dialogue systems and investigating the sharing of personal information between humans in chat-oriented dialogues.

Harshita S.

Harshita is a third-year computer science Ph.D. student at Emory University, where he is part of the Information Retrieval lab. Harshita's research interests include conversational search, personalized recommender systems, and knowledge graphs.

James F.

James is a first year Ph.D. student and is passionate about natural language processing and, more broadly, artificial intelligence as a whole. James has three years of experience in task-oriented human-robot dialogue research, and hopes to further explore techniques for human-computer dialogue in more open-domain, chat oriented dialogues. His current research also includes a project focusing on information extraction from unstructured text in the news domain.

Zihao W.

Zihao is a thrid year Ph.D student in Computer Science at Emory University. His research interests lie in Conversational AI, especially in response ranking and selection in dialogue systems. Zihao participated in the Alexa Prize competition in 2017 and 2018 which were great experiences for him. Zihao has had internships in IBM Research China and Uber AI, in which he worked on different scopes of interesting projects.

Ali A.

Ali is a third year Ph.D. student in Computer Science and obtained their Master's degree in Artificial Intelligence. Ali was a team member in the 2017 and 2018 Alexa Prize competition, and the team achieved 5th and 4th in the final ranking in 2017 and 2018, respectively. Ali mainly worked on the design of the multi-level intent and topic classifier, the proactive recommendation mechanism, and several other information retrieval components such as News and Movies. Furthermore, Ali has been working on procedural question-answering by experimenting with different information retrieval, and deep learning methods.

Jason C.

Jason is a graduate student at Emory University specializing in open-domain spoken conversational systems, mainly in ML & NLU & IR aspects. He is also a returning member from the 2017 & 2018 Alexa Prize. Jason's research focus will be on dialogue management that integrates conversational satisfaction prediction, neural response generation, failure detection & recovery and phonetic language representations. With these signals, Jason looks forward to improving the team's existing system to maintain a more natural conversational flow in a more intelligent way.
