About Me

 I am a fifth year PhD student at the Language Techologies Institute. I am from Tegucigalpa, Honduras: a beautiful city, home to one of the world's shortest airport runways! Before coming to the LTI, I completed the Masters in Information Systems Management program, also at CMU. My undergraduate studies were in Electrical Engineering and Economics at Washington University in St. Louis.

I expect to graduate in the early summer of 2011. Here is my CV

Research and Interests

 I conduct research in Information Retrieval (IR) under the supervision of Jamie Callan. Within IR, my main focus has been on aggregated search—the task of providing users with integrated access to multiple search services within a single system. In particular, my thesis is on aggregated search within the context of Web search, which is a task familiar to many. In addition to retrieving Web content, commercial search engines also function as a single point of access to specialized services known as verticals (e.g., image search, video search, news search, local search, driving directions, weather forecasts, etc.). My methods address the task of deciding when and how to surface vertical content in response to a Web search query. In addition to IR, I am also interested in machine learning, human-computer interaction, and text data-mining.

Prior to working on aggregated search, I conducted research in various areas of information retrieval. I worked on blog retrieval—the task of retrieving blogs with a recurring interest in the topic of the query. Also, within the eRuleMaking Project, I worked on semi-supervised methods for identifying stakeholder communities and recognizing evidence-citation in public comment corpora (emails sent by the public to a government agency that is proposing new regulation).

During my masters, I worked with Carolyn Rosé on developing tools for authoring computer dialogue systems from transcribed task-oriented human-human conversations. My focus was on topic-segmentation of transcribed dialogue and on developing visualizations and interactions for organizing dialogue-segments into thematic clusters.
