### Contact Information
* **E-mail:** agravano [at] utdt.edu
* **Mailing address:** Av. Figueroa Alcorta 7350 (C1428BCW) Buenos Aires, Argentina
* **Phone:** (+54 11) 5169-7810
### Research Interests
* **Artificial Intelligence**, **Speech Processing**, **Spoken Dialogue Systems**, **Prosody**.
* Understand and model the extraordinary degree of coordination exhibited by human beings while holding a conversation, along several dimensions of speech. This knowledge can then be applied to automatically analyze dialogue, or to improve the naturalness of spoken dialogue systems.
* Contribute to the development of speech technologies in Spanish, by creating new resources, such as corpora and tools specific to this language.
### Short Bio
Agustín Gravano was born in Buenos Aires, Argentina, in 1977. He received his B.S. in Computer Science from University of Buenos Aires in 2001, and his Ph.D. in Computer Science from [Columbia University](http://www.cs.columbia.edu) in 2009 (Thesis: "[Turn-Taking and Affirmative Cue Words in Task-Oriented Dialogue](phd-thesis.php)"; advisor: [Prof. Julia Hirschberg](http://www.cs.columbia.edu/~julia/)).
Later that year, he joined the [Computer Science Department](http://www.dc.uba.ar/) at University of Buenos Aires, first as a postdoctoral researcher, and in 2011 as a full-time professor. Since 2020 he has been a full-time professor in the [Business School at Universidad Torcuato Di Tella](http://www.utdt.edu/negocios), where he chaired the [B.Sc. in Digital Technologies](http://www.utdt.edu/digitaltechnologies) from 2020 to February, 2025. His main research interests revolve around modeling the rich coordination present in spontaneous spoken dialogue along several dimensions, including lexical and prosodic, with applications in spoken dialogue systems and automatic conversation analysis.
Dr. Gravano has been a member of Argentina's National Research Council ([CONICET](http://www.conicet.gob.ar/)) since 2010. He has vast teaching experience and has received the [ISCA Award for the Best Paper Published in CSL 2011-2015](files/award-csl-2016.jpg), among other honors.

### Resources
* [UBA Games Corpus](https://ri.conicet.gov.ar/handle/11336/191235). Corpus of direction-giving monologues (both spontaneous and read), and spontaneous, task-oriented, collaborative dialogues elicited from native speakers of Argentine Spanish. It includes audios, orthographic transcriptions and other annotations.
* [Entrainment metrics](entrainment-metrics.php?l=en). Python library for measuring the degree of *entrainment* in a dialogue, defined as a speaker's tendency to adapt their speech to match their interlocutor's.
* [Spanish DAL: Spanish Dictionary of Affect in Language](sdal.php?l=en). Spanish lexicon manually annotated for three affective dimensions: pleasantness, activation and imagery.
* [Contextualized Hate Speech](https://ri.conicet.gov.ar/handle/11336/235509). Collection of tweets in *Rioplatense* Spanish, published in response to news media articles. Each tweet has been manually labeled with respect to various dimensions of hate speech.
