About Me

Hey, I am Cristina Segalin!
I am a postdoctoral scholar at Caltech, Pasadena, CA.

I attended a bachelor degree in Multimedia Information Technology at the University of Verona, where I was mainly interested in Computer Vision, Augmented Reality and Human Computer Interaction, Image Processing, Computer Graphics and also Psychology of Perception. My bachelor degree thesis proposed a face recognition system, that has been installed at the door of the VIPS laboratory of the University of Verona. I attended the master degree on Engineering and Computer Science, in the same university, taking lectures in Computer Vision, Pattern Recognition, which helped me to discover my desire to work on my own project, through a possible PhD. My master thesis focused on the research field of Social Signal Processing (SSP), the domain aimed at modeling, analysis and synthesis of nonverbal communication in human-human and human-machine interactions. The purpose of the thesis was the person re-identfication through the way people chat with other subjects. During that period, I was lucky enough to work also on other research projects, like recognizing the age of children by the way they talk with each other. SSP together with, Social Media Analysis, Personality Computing, ML, PR and CV became the main topics of my PhD at the Dept. of Computer Science in Verona (Italy).

During the first year of PhD I investigated the interplay between aesthetic preferences and individual differences, under the supervision of Marco Cristani. I had the great opportunity to move to Glasgow for some months and collaborate with Alessandro Vinciarelli to this project. I collected a dataset of 60K images favorited from Flickr users, extracted features coming from the field of Computational Aesthetics (CA), and predicted from them the personality of a user. Continuing on the perspective of CA, we also proposed a soft biometrics application where the goal is to recognize people by considering the images they like as a new biometric trait. At the end of the second year of PhD I moved for some months in Birmingham to collaborate with Mirco Musolesi with the aim of investigating the role of textual, visual and social cues in information propagation in Twitter. My last contribute during the PhD was in the field of Deep Learning and Feature Learning, trying generalize the particular cues that characterize each personality trait.

While waiting to defend my Phd thesis, I worked as research associate at Disney Research in Pittsburgh (PA) under the supervision of Maarten Bos. After my graduation, I moved to Pasadena (CA) to work as postdoctoral scholar at California Institute of Technology (Caltech), in the Computational Vision Lab, under the supervision of Pietro Perona and to collaborate with David Anderson. Here I work on animal behavior, in particular, Computational Ethology, which involves biologists and computer scientists with the common goal of understanding, analyzing, measuring and describing animal behavior using Machine Learning and Machine Vision algorithms and tools. My role here is to develop a novel system able to detect, track and recognize mice actions on videos.
