Thomas Ploetz

I am a Reader in "Computational Behaviour Analysis".

My research agenda is centred on Applied Machine Learning for Computational Behaviour Analysis (CBA), that is I am interested in building computational systems for understanding behaviour through analysing activities. Behavioural data is thereby captured in an opportunistic way and utilising a variety of sensing modalities, most notably ubiquitous and wearable sensors but also cameras, or microphones. This agenda is driven by two main research questions:

  1. How can we design machine learning methods that are robust and reliable for real-world applications with specific focus on sensor data analysis?
  2. How can we build methods and systems that enable objective and accurate assessments of behaviour in naturalistic settings and thus directly contribute to improved understanding of behaviour with specific focus on health and wellbeing.

The key to these is fundamental research in ubiquitous and wearable computing, and specifically in innovative machine learning techniques with strong focus on their application related challenges. As an applied computer scientist I aim for the development and real-world deployment of innovative data analysis techniques beyond artificial settings, which typically comes with an additional and very different set of challenges beyond core method development.

The central theme of my research is to develop techniques and systems that actually have an impact on people's life. Therefore, my research is almost always connected to some practical application (in contrast to purely theoretical work) and I am keen on deploying systems I develop in the "wild", i.e., in real-world settings. The most prominent domain for this kind of work is health, where I am working on computational assessments of behavioural phenotypes of, for example, Parkinson's, Dementia, or Autism.

    Through sensors worn on the body or embedded into objects of daily use we can infer the activities performed by a subject. Extracting the characteristics of the data collected by these sensors, i.e. how these activities were performed, would be ben...

  • ACCEL-O-SURG
    The aim of this project was to understand the changes in motor skill that take place during the early phases of learning a new fine motor skill task. For this project specifically, that motor skill was suturing, which we measured by attaching senso...
