Introduction
My research combines behavioural and neuroimaging techniques in order to investigate how spatial information is encoded and used to guide navigation. I am interested in understanding individual differences in navigation ability and the extent to which locomotion and wayfinding depend on amodal spatial representations. Recently, I have investigated how physiological measures (e.g., EDA, HR) mediate behavior in real and virtual environments. Much of my research relies on the development of immersive virtual environments that can mimic real-world situations. As such, I have worked with computer scientists to develop a framework (EVE) to facilitate the design and implementation of experiments in virtual reality. This work has resulted in projects in the digital humanities and public health.

The idea that humans use flexible map-like representations of their environment to guide spatial navigation has a long and controversial history. One reason for this enduring controversy might be that individuals vary considerably in their ability to form and utilize cognitive maps. Here we investigate the behavioral and neuroanatomical signatures...
Spatial navigation in the absence of vision has been investigated from a variety of perspectives and disciplines. These different approaches have progressed our understanding of spatial knowledge acquisition by blind individuals, including their abilities, strategies, and corresponding mental representations. In this review, we propose a framework...
Living in a disadvantaged neighborhood is associated with worse health and early mortality. Although many mechanisms may partially account for this effect, disadvantaged neighborhood environments are hypothesized to elicit stress and emotional responses that accumulate over time and influence physical and mental health. However, evidence for neighb...
Exploring a city panorama from a vantage point is a popular tourist activity. Typical audio guides that support this activity are limited by their lack of responsiveness to user behavior and by the difficulty of matching audio descriptions to the panorama. These limitations can inhibit the acquisition of information and negatively affect user exper...
The role of affective states in learning has recently attracted considerable attention in education research. The accurate prediction of affective states can help increase the learning gain by incorporating targeted interventions that are capable of adjusting to changes in the individual affective states of students. Until recently, most work on th...
Hippocampal atrophy is a hallmark of Alzheimer’s disease and is associated with deficits in navigation. We investigated whether a novel digital assessment, the Spatial Performance Assessment for Cognitive Evaluation (SPACE), can predict hippocampal integrity beyond traditional neuropsychological tests in older adults. Forty older male participants...
Unlike classic audio guides, intelligent audio guides can detect users’ level of attention and help them regain focus. In this paper, we investigate the detection of mind wandering (MW) from eye movements in a use case with a long focus distance. We present a novel MW annotation method for combined audio-visual stimuli and collect annotated MW data...
INTRODUCTION: Alzheimer′s disease affects spatial abilities that are often overlooked in standard cognitive screening tools. We assessed whether the spatial navigation tasks in the Spatial Performance Assessment for Cognitive Evaluation (SPACE) can complement existing tools such as the Montreal Cognitive Assessment (MoCA).
METHODS: 348 participants...
Age-related cognitive decline associations with human electroencephalography (EEG) have previously focused on periodic activity. However, EEG is primarily made up of non-oscillatory aperiodic activity, which can be characterised with an exponent and offset value. In a secondary analysis of a cohort of 111 healthy participants aged 17 – 71 years, we...
The Spatial Performance Assessment for Cognitive Evaluation (SPACE) is a novel iPad serious game designed to identify differences in spatial ability indicative of early signs of cognitive impairment.

SpecParam (formally known as FOOOF) allows for the refined measurements of electroencephalography periodic and aperiodic activity, and potentially provides a non-invasive measurement of excitation: inhibition balance. However, little is known about the psychometric properties of this technique. This is integral for understanding the usefulness of S...
Parkinson's disease (PD) has been associated with greater total power in canonical frequency bands (i.e., alpha, beta) of the resting electroencephalogram (EEG). However, PD has also been associated with a reduction in the proportion of total power across all frequency bands. This discrepancy may be explained by aperiodic activity (exponent and off...
Background
Heart rate variability biofeedback (HRV-BF) can be used for stress management. Recent feasibility studies suggest that delivering HRV-BF in virtual reality (VR) is associated with better user experience (UX) and might yield more beneficial changes in HRV than two-dimensional screens. The effectiveness of a VR-supported HRV-BF interventio...
Gender differences in navigation performance are a recurrent and controversial topic. Previous research suggests that men outperform women in navigation tasks and that men and women exhibit different navigation strategies. Here, we investigate whether motivation to complete the task moderates the relationship between navigation performance and gend...

Digital maps on personal devices (e.g., phones) are common tools used to aid navigation. Different types of digital maps can influence spatial knowledge acquisition, and this effect might depend on whether the user interacts with an forward-up or north-up map. In spatial cognition theory, these differences can be used to support either sequential o...
Approximately 40-60% of falls in the elderly lead to injuries, resulting in disability and loss of independence. Despite the higher prevalence of falls and morbidity rates in cognitively impaired individuals, most fall risk assessments fail to account for mental status. In addition, successful fall prevention programmes in cognitively normal adults...

The collective behavior of human crowds often exhibits surprisingly regular patterns of movement. These patterns stem from social interactions between pedestrians such as when individuals imitate others, follow their neighbors, avoid collisions with other pedestrians, or push each other. While some of these patterns are beneficial and promote effic...
Cognitive neuroscience can provide novel and interesting techniques for investigating spatial and geographic thinking. However, the incorporation of neuroscientific methods still lacks the theoretical motivation necessary for the progression of geography as a discipline. Rather than reflecting a shortcoming of neuroscience, this weakness has develo...
Telling stories is as old as humanity. It was Herodotus (484-425 BCE), the Greek scholar often known as the "father of history", who proclaimed in The Histories both our collective reasons and worries about preserving stories. He wrote:
