Andrea Pozo Estívariz

PhD Student, GRI


Geospatial Analysis

I am a civil engineer from Spain. Since my Master’s I have been working in the GeoOcean research group (University of Cantabria), having the opportunity to deep into different research topics such as the development and prediction models for tropical cyclone activity, wave modelling, rain fields parameterization or flood modelling and mapping. I have just started my PhD in the area of water resource management, focused on the development of advancing methods of rapid flood risk scenario assessment using hybrid approaches of hydraulic modelling and machine learning.


My PhD is supervised by Prof. Matt Wilson (UC), Dr. Emily Lane (NIWA) and Prof. Fernando Méndez (University of Cantabria, Spain) and it is part of the MBIE Endeavour research programme, “Reducing flood inundation hazard and risk across Aotearoa/New Zealand”. I am very motivated because this programme not only offers me the chance to work with cutting-edge techniques and learn more about such interesting topics for me like climate change; but also I feel I can contribute with my work to improve the quality of life of all the people who suffer from floods.

David Pedley

PhD Student, GRI


Geospatial Analysis

David has a professional background as an environmental lawyer and has recently completed a Master’s degree in landscape architecture at Lincoln University. Through this experience, David has established a strong interest in the potential of geospatial analysis to help develop effective solutions to complex environmental problems. David’s PhD is in urban forestry and will focus on the conflict between housing intensification and the loss of urban trees on private residential land in New Zealand cities. This research will incorporate deep learning techniques to detect changes in canopy cover over time and explore potential solutions to increase the retention of urban trees in the face of ongoing intensification pressure. David is very grateful for the opportunity to pursue this research through the Geospatial Research Institute Toi Hangarau PhD Scholarship, working alongside supervisors Dr Justin Morgenroth and Dr Grant Pearse.

PhD Student, Geo Health Laboratory


Susie (Bingyu) Deng is a PhD candidate in Health Geospatial Science. Her skills include GIS analysis, longitudinal modeling, and programming. Her research primarily focuses on the impact of neighbourhood on health and wellbeing, with a particular focus on greenspaces and mental health. A broad question that her research will answer is, do the places where people lived have an impact on people’s health? Her objectives include investigating people’s migration patterns throughout their lives, evaluating socioecological exposures of places where people lived, examining the association between the accumulated socioecological exposures throughout people’s lives with their subsequent mental health conditions.

Dr Marwan Katurji

Rutherford Discovery Fellow, Senior Lecturer in Atmospheric Dynamics,  School of Earth and Environment, University of Canterbury

Dr Marwan Katurji specialises in surface-atmosphere interactions. His research interest is in modelling, simulating, measuring and analysing atmospheric phenomena, using advanced in-situ, aerial and remote sensing measurements and numerical modelling techniques. He is developing new approaches to tackle fundamental research questions in the field of atmospheric boundary-layer turbulence that leverages on a multidisciplinary approach of engineering and science. Marwan is particularly interested in coherent turbulent structures within the first 1km of our atmosphere above ground level (also called the atmospheric boundary-layer). These structures form the unique fabric of turbulence that controls the spatial variability of temperature and moisture across our landscape.

Justin Morgenroth

Associate Professor, Postgraduate Director of Studies, School of Forestry | Kura Ngahere, University of Canterbury

I’m interested in understanding urban trees and the critical roles they play in cities around the world. The trees that comprise urban forests face considerable abiotic and biotic stress, but help to make cities liveable, providing residents with healthy, sustainable, and desirable places to live and work. To that end, I research the growth, function, management, and ecosystem services of trees in urban environments. To do so, I work extensively with remote sensing or earth observation techniques, including lidar, as well as aerial and satellite imagery.

Ben Adams

Ben Adams

Associate Professor, Dept. of Computer Science and Software Engineering, University of Canterbury

In my research I am exploring new ways of using computing technology to advance human understanding of our environment and world. I am interested in understanding, modelling, and improving how the people who want to learn about the world (e.g., scientists, students, and policy makers) interact with and make decisions based on geographic knowledge represented in a computer. The research I undertake is both explanatory and constructive. In the first case I work to develop theories that explain how the information that we produce and share in digital form reflects human conceptualizations of the world. In the second case I build software systems that help people use geographic information better to solve problems. My research methodology is informed by methods from data science, machine learning, spatial information science, interactive systems, and cognitive science.

Research interests include three areas, broadly linked by relationships between transport and health. These are:
1. Air pollution exposure – This addresses the question of how we quantify the amount of pollution humans actually breathe in. This is important to know if we want to relate pollution to human health.
2. Transport – This research area is interested in how we can make transport more sustainable and looks at people’s perceptions and attitudes to transport, focusing specifically on school and work travel.
3. Health geography – This focuses on links between spatial patterns of illness and air pollution.
