- May 2010 - present: In collaboration with my research advisor (Dr. Chirag Shah) we designed a user study to explore the behavior of users in an informaion seeking collaborative task. The design also involved the development, update, and integration of different software that later were used in the data collection process. So far I have collected multimodal data from 170 users. This data is being analyzed using both quantitative and qualitative methods.
- Jan 2010- present: As part of my course work, I become interested in social media and natural language processing (NLP). One of my main interest in this regard was the expression of sarcasm in online communities, specially in Twitter. With Dr. Smaranda Muresan and Dr. Nina Wacholder, we have been investigating to what extent it is possible to automatically identify sarcasm in Twitter using machine learning techniques.
- Mar 2005 – Dec 2006: As part of my master thesis, I ran a study with 56 users grouped in teams of four. The aim of this research was to study the influence of resources for enhancing the emotional awareness of users in a particular collaborative task. The study involved the development of a distributed collaborative game and an emotion recognition system. In 2007, Dr. Edmundo Leiva and I were interviewed by CNN Español about this project (See the video below).
