Advancing movement & sleep research

By Dr. Vincent van Hees

As creator and developer of R package GGIR, Open Source software for analysing accelerometer data, I am committed to improving the quality of research into human movement and sleep. In collaboration with fellow researchers and developers across the world I aim for solutions that are efficient and reusable.

GGIR Software

I created GGIR in 2013 as a generic solution to handle and analyse the data collected with modern accelerometers. GGIR facilitates: data reading, data quality assessment, generation of basic descriptive reports about a person’s movement, sleep detection and the detection bouts of time spent in acceleration ranges while allowing for short gaps in behaviour.

Testimonials

"Being able to access Vincent’s expertise and support through his consultancy service is very important to us. He has developed bespoke accelerometer data processing options that can be applied at scale, enabling us to get more from our datasets and advancing our research."
Dr. Alex Rowlands
Diabetes Research Centre, University of Leicester, Leicester General Hospital, Leicester, UK
"Accelerometer data are an amazing source of information, but how to extract this information? How to detect sleep, derive time in activity levels, create fragmentation indices, extract time-series for functional data analysis…? Vincent found solutions for all of them while working collaboratively with me and my team. A very good experience!"
Dr. Séverine Sabia
Université de Paris, Inserm U1153, France; University College London, UK
"We are very excited to collaborate with Dr. Vincent van Hees in analyzing the accelerometry data of our large German National Cohort (NAKO). Vincent has an outstanding ability to develop and apply scientific software and algorithms to process movement data. It is a great pleasure to work with him!"
Dr. Michael Leitzmann
Dept. of Epidemiology and Preventive Medicine, University of Regensburg, Germany
