Social Computing Group

Daniel Gatica-Perez I am Head of the Social Computing Group at Idiap and Professor at EPFL. I am interested in methods that integrate ubiquitous computing, social media, machine learning, and social sciences to understand human and social behavior and to create applications for social good.

postdoctoral researchers

Joan-Isaac Biel I am a postdoctoral researcher at Idiap. I got my PhD at EPFL in 2013. I graduated in Electrical Engineering (MSc) from the Technical University of Catalonia (UPC, Barcelona) in 2008, and I was visiting researcher at the International Computer Science Institute (ICSI, Berkeley) between 2008 and 2009. My research area of interest is the analysis of sensor data both offline and online with the purpose of understanding human social behavior and communication, as well as to explore how people engage and experiment with multimedia content. My doctoral research was focused on the analysis of human communication, interaction, and multimedia engagement with online social video in sites such as YouTube, addressing the automatic analysis of conversational video blogs (vlogs).

Rui Hu I joined Idiap in September 2013 as a post-doctoral researcher. My research interests include computer vision, pattern recognition, and visual information retrieval. I recently finished my PhD at the Center for Vision, Speech, and Signal Processing (CVSSP) at the University of Surrey. My PhD thesis was about "Visual Information Retrieval using Annotated Free-hand Sketches".

Laurent Nguyen I am a postdoctoral researcher at EPFL and Idiap. My research lies in the fields of computer vision and pattern recognition applied to social computing and social psychology. I got my PhD from EPFL in 2015, investigating the use of nonverbal cues to predict outcomes and behaviors in job interviews. I am particularly interested in the links that can be made between engineers and psychologists. I graduated from EPFL in 2006 (MSc in microengineering and robotics) and worked as a junior researcher at EPFL as part of my Swiss civil service.

Darshan Santani I am a postdoctoral researcher at the Social Computing Group at Idiap. I recently got my PhD at EPFL. My research interests lie broadly at the intersection of computer science and social science, in particular application of large-scale (mobile) data mining to various social and urban contexts. Before joining Idiap I completed my Masters at ETH Zurich.

doctoral students

Gulcan Can I obtained my Bachelor degree in Computer Engineering from Bilkent University in Ankara, Turkey in 2010. I completed my M.Sc. studies at the Middle East Technical University in Ankara in 2013. I am currently a fourth-year PhD student at Electrical Engineering at EPFL. My current research interests are probabilistic graphical models and their applications, and representational learning with sparse methods.

Skanda Muralidhar I completed my master's studies at the National University of Singapore in 2014. I am currently a third-year PhD student at Electrical Engineering at EPFL.

Trung Phan Thanh I am a second-year doctoral student at Idiap adn EPFL. I graduated with a B.Sc degree in Information Technology from University of Science, Vietnam National University, Ho Chi Minh City (VNU-HCMC) in 2010. I obtained my Master of Engineering in Multimedia and Communication from Telecom ParisTech, France in 2013. I am interested in the connections between computer science and social sciences.

student interns

Jing Yang I am currently a Research Intern at Idiap. I did my master's in Electrical Engineering and Information Technology at ETH.
