PhD position - Multimodal Methods for Depression Detection F/M

Role Summary

We are seeking a PhD student to develop multi-modal, gender- and culture-aware deep learning techniques for analyzing and classifying various depression disorders using clinical interviews.  
Funded by the Swiss NSF, the project is a collaboration between the Idiap Research Institute in Switzerland, the Department of Computer Science of the Mathematics Research Center (CIMAT), in Mexico and the  Department of Epidemiological and Psychosocial Research from the National Institute of Psychiatry Ramón de la Fuente Muñiz (INPRFM) in Mexico.
Worldwide, mental disorders significantly affect individuals' disability-adjusted life years. Timely detection and treatment are critical challenges for healthcare institutions in ensuring access to appropriate care options. The primary goal of the project is to develop AI-based solutions to assist experts in the diagnosis of depression disorders, including symptom identification, risk factor assessment, disease progression predictions, and online psychometric tools.
The approaches to be developed aim to learn embedding vectors by modelling relationships across different modalities of data (speech, video, text, experts' knowledge) while maintaining transparency and interpretability, which is especially crucial in health-related applications. A significant challenge arises when integrating multi-modal information, as each data source differs in nature. Additionally, the models will be designed to be culturally and gender-aware, ensuring that these factors are considered in the learning process. Defining how to model long-distance semantics and prosodic abnormalities using these diverse sources of information will be among the core challenges to be addressed.
At Idiap, the project will build on our recent work that has shown that Graph Convolutional Networks are plausible solutions for training a depression detection model from transcribed clinical interviews. All work will be conducted in close collaboration with our partners in Mexico, CIMAT and the INPRFM. The INPRFM will serve as our clinical partner, providing access to clinical data and offering feedback on the psychological aspects involved in the development of the proposed solutions, ensuring their reliability. Meanwhile, CIMAT will be our technical partner, contributing to the development of AI and deep learning methodologies that will play a critical role in achieving the project's overall objectives. The successful candidate will spend around half a year of their study seconded to Mexico, with a counterpart in Mexico also spending half a year at Idiap.
