Job description

Are you interested in developing advanced statistical models? And would you like to open the way for new forms of real-time mood sensing going forward? The department of Methodology and Statistics has a job opening for a PhD candidate, interested in developing advanced statistical models to detect episodes of depression in real-time.

Your job
The project is a close collaboration between the department of Methodology and Statistics and the department of Youth and Family. Depression prevalence in emerging adults is alarmingly high. To advance clinical care for this at-risk population, we need to exploit technological advances such as smartphones and wearables to move beyond the current univariate and time-static standards. Smartphones and wearable devices facilitate densely spaced longitudinal measurements, enabling the study and monitoring of behaviour and mood dynamics unfolding over time. Pairing novel statistical models with these dense measurements presents the unique opportunity to unveil the nature and temporal structures of emerging adults’ affective, behavioural and social experience in depressed mood at a personalised level, which can be exploited for prediction.

You will develop and validate a probabilistic unsupervised learning method, which utilises deep phenotyping data to anticipate increases in psychopathological symptoms in real-time. The ideal statistical method:
  1. accommodates the latent and multivariate property of mood;
  2. characterises mood in a set of distinct, mutually exclusive latent states;
  3. obtains the dynamics between the latent mood states over time;
  4. adopts a personalized approach; and
  5. explicitly and accurately models the durations of the latent mood states.

The extended (multilevel) hidden Markov model ticks all above boxes and will be used as our starting point. You will implement the developed algorithm in a statical package within the open statistical software environment R. To validate the model, you will conduct an extensive simulation study on the estimation and prediction performance of the developed algorithm. In addition, you will set up a study to obtain an extensive longitudinal (6-weeks, 5-daily) deep phenotyping dataset on multiple affective and behavioural experiences previously associated with depressed mood. By combining the obtained deep phenotyping data with the developed personalised depression prediction algorithm, you can derive empirically derived depressive-mood states that reflect the multidimensional complexity of depression, examine the dynamics over time in depressed mood, infer personalised model parameters, and set a first step towards real-time personalised prediction of depressed mood episodes.

The position also includes between 10% and 20% teaching tasks at the department of Methodology and Statistics of the faculty of Social and Behavioural Sciences.
