About Me

Since my time of scrambling over mountains and through bat guano, I have accumulated considerable and varied research experiences as an active researcher and educator.  I use GIS, big datasets, and a variety of geospatial computational and analysis methods to address applied research questions across a range of topics from sinkholes to sky islands, tornadoes, malaria and migration, among others.  At its core, my research has focused on broad issues related to human health, particularly in relation to climate and climate change, examining causes and consequences from local to global spatial and temporal scales, and anywhere in between that is relevant to the system of study.

As the quantity and availability of geospatially enabled data continue to increase, so do the concomitant challenges and opportunities associated with the appropriate gathering, analyzing and dissemination of the findings from these data.  Spatial Data and GIScience clearly play a central role in addressing the health of our planet and, from an educational perspective, I am interested in expanding and strengthening Spatial Data and GIScience education, as well as building scholarly communities and networks to foster multi-disciplinary research and education.

Areas of Expertise: GIS, Spatial Data Science, geohealth, planetary health, spatial analysis, education


It is an exciting time to be in the field of GIS/ Geospatial (Data) Sciences! Technologies have evolved making the collection and communication of spatial data much easier. Although there has been an explosion in the availability of geospatial data, asking pertinent questions and sifting through streams of data to make sense of the world in which we live, remains a challenge.

The fun part of using GIS/Geospatial (Data) Science and Spatial Analysis is that it can be applied to all disciplines to view where something is, explore patterns, relationships and interactions, model different outcomes and develop hypotheses whether this ranges from sports analysis to disease risk. In general, I am interested in using Geospatial technologies and GIS/Spatial Data Science:

  • to better understand mechanisms influencing health and well-being at different scales across space and time
  • to leverage diverse data sources to understand changing risks;
  • to determine how we can effectively integrate these into a framework that enhances decision-making processes and provides sustainable solutions.


GeoHealth, Planetary Health, Public Health, One Health?

Sixty percent of all human infectious diseases are transmitted from animals and microbes of animal origin. These ‘spill over’ due to increasing contact among wildlife-livestock-humans often driven by exponentially growing anthropogenic changes caused by human activities (e.g. changes in land use, changes in climate, changes in food security, changes in politics and changes in infrastructures (e.g. digitalisation, transportation networks, water & sanitation, etc.)) and the impacts of these activities on the environment.  

Over the past ten years, many outbreaks and pandemics have occurred with varying duration and intensity. Between 2012 and 2017, the World Health Organisation (WHO) recorded more than 1,200 outbreaks in 168 countries, with a further 352 infectious disease events in 2018. Some of these have been localized, while others have spread globally in a short period as recently witnessed with COVID-19. The risk of pandemics continues to increase rapidly, with more than five new diseases emerging in humans every year, any one of which has the potential to spread and become a pandemic. The circulation, transmission and evolution of diseases are driven by a range of factors (environmental factors, host-related factors and the pathogen itself) and how they interact in space and time.  

We integrate a variety of data (some novel, some volunteered, some authoritative, some big and messy) in a GIS and use a mix of spatial analysis, data science, machine learning methods and mathematical and geocomputational models to address applied research questions across a wide range of topics that include different aspects of health. Our work centers around three main facets:

  • understanding the ecology of disease/health across space and time (host-pathogen-environment interactions in dynamically changing environments) and what this means for health and disease outcomes;
  • how to respond, and;
  • what to communicate how.

We examine how changes in environments such as climate drive health and disease dynamics as it relates to

  • vector-borne diseases (e.g. mosquito-vectored diseases such as dengue and malaria; tick-vectored diseases);
  • disaster epidemiology (risks pre, during and post weather risk events);
  • extreme weather (e.g. heat, floods);
  • food security (e.g. effect of frost-freeze events on the environment in intense agricultural cropping systems; when and where biopesticides can be used for controling agricultural pests)
  • accessibility (e.g. seasonal effects of access to healthcare and the use of different modes of transport to access healthcare)
  • mobility (e.g. climate-drivers and how they contribute to mobility and disease circulation and transmission)
  • communication (e.g. data structuring for effective communication; what is being communicated)
  • etc...



The COVID-19 pandemic forced educational institutes to pivot their F2F learning environments to online learning environments and has subsequently transformed societal expectations about education. Although there are many benefits associated with these changes in education (e.g. multi-dimensional interactions, flexibility and richer/deeper learning) there are still many challenges that can result in poor and often inadequate educational experiences (e.g., lack of real student-student and student-teacher interaction, and effective discussions).

Alongside this we have seen a rise in AI technologies and methodologies being used to answer questions via chat bots, create images, enhance our computing capabilities and drive many common household items such as the vacuum cleaner, much of which are using technologies and methods being developed in the geospatial field. These technologies and methods are already very much part of our daily lives.

How do we ensure we, as educators are at the forefront of these developments and are incorporating these into our curriculums? How do we maintain the geospatial aspects of our curriculums? What resources, skills and communities are needed?

For education and in particular geospatial education, I am interested in:

  • expanding and strengthening Geographic Information Science education;
  • improving the uptake and use of GIScience methods in the health science;
  • building scholarly communities and networks to foster multi-disciplinary GIScience education & research;
  • promoting education that balances interactions in both a face-to-face and online learning environment.

As an academic who has taught in a program geared towards working professionals, and who has also worked outside of academia, I appreciate the many levels of education needed to help students and professionals develop skill sets that enable them to excel within the realm of GIS, GIScience and the Spatial Data Sciences across a wide range of disciplines and industries.  As a result, I am interested in enhancing online/blended learning experiences for students (and staff) by promoting student scholarship that enables the exchange of knowledge, enhances collaborations between students, and builds professional social networks.
