Bob van Hilten, MD, PhD

Leiden, Nederland, 01-01-2009 Universiteit Leiden, LUMC, neurologie J.J. van Hilten, prof foto: Marc de Haan/ Hollandse Hoogte

J.J. (Bob) van Hilten is professor in Movement Disorder Neurology and chair of the neurology residency program at the Leiden University Medical Center. He has a longstanding experience in research in the field of PD and other movement disorders and was one of the first researchers to explore the potential of wearable technology in the assessment of PD. He is the PI of the Technology in Motion consortium, as well as the SCOPA-PROPARK project (funding 1998 – onward) in which measurement instruments were developed to evaluate PD (SCOPA-rating scales), and subsequently research has focused on profiling of patients (PROfiling PARKinson: PROPARK) on different levels, i.e. clinical, MRI, molecular and genotype, with the ultimate objective to obtain a better understanding of how underlying pathobiology influences phenotypic expression of the disease. The PROPARK cohort is one of the most extensively characterized cohorts of PD patients worldwide, which is the reason why this cohort participates in the International Parkinson Disease Genomics Consortium. From 2004 to 2012, Bob van Hilten was the scientific director of the TREND research consortium, which focused on Complex Regional Pain Syndrome and provided a substantial contribution to the understanding of the disorder and laid the basis for international collaboration of researchers in this field. For the collective effort he was awarded by the queen the title of Officer of the Order of Orange-Nassau. Bob van Hilten has published over 225 peer-reviewed papers, with an H-index of 43.

Linda van Schaik – Bank, PhD

Linda BankLinda van Schaik – Bank has been working at the LUMC Department of Neurology since 2009. Her research has focused on the assessment of arm and hand motor function in patients with neurological disorders such as stroke, Parkinson’s Disease, and Complex Regional Pain Syndrome. As a human movement scientist, she strives to build a bridge between clinicians and engineers involved in the TiM project, working together to develop a low-cost setup for unobtrusive and objective quantification of motor (dys)function and its underlying determinants.

Linda has acquired experience with motion analysis in various patient groups and ‘marker-less’ motion capture systems (e.g., based on KinectTM) in her previous research projects (e.g., NEURAS). Within TiM, the marker-less assessment of arm and hand function will be further developed and extended to include augmented reality (AR) for evaluation of reach-and-grasp tasks (together with Marina Cidota) as well as pattern-recognition algorithms (for off-line post-processing of the raw RGB-data and depth data; together with Julian Kooij). Systematic manipulations of task and environmental factors will be exploited to test the patients’ adaptive capacities. This may not only lead to understanding of the motor and cognitive factors contributing to the motor dysfunction of a patient, but may also provide a more sensitive indicator of problems experienced in daily life than currently obtained with standard clinical tests.

Marina Cidota, PhD

Marina CidotaMarina Cidota has been working at the TU Delft since 2014. Her current research is focused on designing for engagement and awareness in a collaborative system, using different interaction techniques and establishing virtual co-location in merging realities. Possible applications can be found in the security domain, in medicine and in certain training contexts. In the TiM project, her research focuses on combining Augmented Reality novel technologies, serious gaming and marker-less tracking of the human body for unobtrusive, cost-effective and patient-friendly methods for objective assessment of upper extremity motor dysfunction.


Daphne Geerse, MSc

Daphne GeerseDaphne Geerse studied Human Movement Sciences at the Vrije Universiteit in Amsterdam and started her PhD research in 2014.

Jurriaan de Groot, PhD

Jurriaan de Groot

Jurriaan H. de Groot received his M.Sc. degree (1988) in Biology from the Wageningen University and his Ph.D. degree (1997) in Biomechanical Engineering from the Delft University of Technology where he defended his thesis ‘The Shoulder, A kinematic and dynamic analysis of motion and loading’. He was a post-doc researcher associated to the dept. of Biology at the Leiden University involved in kinematics and biomechanics of reptile tongues, e.g. snake tongue flicking and chameleon tongue projection.

In 2001 he became senior researcher at the dept. for Rehabilitation Medicine at the Leiden University Medical Center where he heads the Laboratory for Kinematics and Neuromechanics. Since 2008 he hold a position as an Assistant Professor. His research focus is on the biomechanics of the shoulder (massive rotator cuff tears and sub-acromial pain syndrome), and the contribution of neural and non-neural contractile and connective tissue factors in patients with spasticity after Stroke, CP and Spinal Cord Injury.

He is/was principal co-investigator on different Reumafonds, ZonMW and STW funded projects and published over 60 papers in peer reviewed journals.


Julian Kooij, PhD

julian-kooijJulian Kooij performed his PhD research at the University of Amsterdam, during which period he has also been employed in part at Daimler Research and Development, Ulm, Germany. His research interests include machine learning and Bayesian methods for computer vision, with a focus on analysis of motion dynamics. In the TiM project, his research addressed tremor assessment using unobtrusive computer vision methods, and machine learning techniques to detect and classify deviating motion dynamics.  Since May 2016, he is appointed as assistant professor at the Delft University of Technology.



 Stephan Lukosch, PhD

15_10_stephan_squareStephan Lukosch is associate professor at the Delft University of Technology. His current research focuses on virtual co-location. Individuals can be virtually at any place in the world and coordinate their activities with others and exchange their experiences. By using augmented reality techniques to merge realities additional information can be provided and visualized, thereby fostering shared understanding. By merging realities complex problems can be solved, complex trainings can be supervised, or complex activities can be guided without all interacting individuals being physically at the same place. In his research, he combines his recent results from intelligent and context-adaptive collaboration support, collaborative storytelling for knowledge elicitation and decision-making, and design patterns for computer-mediated interaction. In the TIM project, he explores in how far virtual co-location in combination with serious gaming can contribute to an objective evaluation of human motor dysfunction.

Melvyn Roerdink, PhD

Melvyn Roerdink PhD

Melvyn Roerdink is assistant professor at the Department of Human Movement Sciences at Vrije Universiteit Amsterdam. He has a strong track record in applying fundamental theoretical and technical concepts to the study of walking. To better understand walking-related falls, he seeks to attune diagnosis and treatment to major contributors of falls. His research revealed a group-dependent interplay between task complexity, self-selected walking speed, attentional costs of walking, walking performance and task prioritization, implying that for an in-depth understanding of walking one requires a comprehensive assessment. To accommodate that, he invented and developed the patented rehabilitation treadmill C-Mill and the Interactive Walkway, systems augmented with gait-dependent visual context (both systems are commercially available via Motekforce Link, an industrial partner of TIM).

In 2015, he has been awarded as the promising young scientist of the International Society for Posture and Gait Research (ISPGR, Seville, Spain). In the TIM project, he will test the premise that a more task-specific walking assessment yields 1) a better identification of those at risk of falling during walking and 2) a better understanding why someone is at risk, allowing for patient-tailored fall-prevention interventions.
