Roberto I. González-Ibáñez As a computer engineer, I feel a great passion for technology, but at the same time I am deeply intrigued on how the rapid evolution of computers and communication is affecting the way in which people interact with the world; this questioning lead me to pursue an academic career. Since 2005 I have been studying different aspects of computer-mediated collaboration that include emotions, users' behaviors, linguistic aspects, and performance, among others. As a PhD. student I am currently focused on the study of collaboration in information seeking. [Index] Sep 2009 – present : PhD. Candidate – Library and Information Science

[Index] - 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 tasks. The study involved the development of a distributed collaborative game and an emotion recognition system (see a brief description below) [Index] - Coagmento: Originally developed by Dr. Chirag Shah, Coagmento is a system that supports the Collaborative Information Seeking process (CISP) of teams. This tool has been used in controlled and semi-controlled experiments. Currently we are working to make it available to the general public. http://www.coagmento.org - Memorativo (Originally called Memorative): Distributed and scalable game that promotes collaboration among multiple players and enables the researcher to collect multimodal data as well as control different experimental scenarios. This tools has been used in different thesis (including my own Master's thesis) in the Department of Computer Engineer at Universidad de Santiago de Chile. [Video] - BMERS (Basic Mood and Emotions Recognition System): Based on facial expressions, this tool recognizes six basic emotions, neutrality, and is able to infeer four basic moods using machine learning techniques. This tool can be integrated with other systems as a complement of other communication channels. [Video] - EMERA: This Web-based system was specifically developed for a small company that distribute electricity in a region of Chile. This tool allow employees to manage the main business' processes of the company. In addition it provides online services to customers with relevant information about their bills, payments, energy consumption, and others.http://www.emera.cl [Index] Doctoral Program
