Current Lab Members
Justin Morgenroth
Urban forestry, forestry, remote sensing, geospatial science
Professor Justin Morgenroth leads the ‘Remote Sensing and Geospatial Analysis Research Group’ at the School of Forestry. He’s interested in describing the spatial and temporal dynamics of New Zealand’s urban forests, indigenous forests, and exotic forest plantations using a range of quantitative techniques. He works extensively with remote sensing or earth observation techniques, including lidar, as well as aerial and satellite imagery. He holds a BSc in Computer Science (University of Western Ontario), a Masters in Forest Conservation (University of Toronto), and a PhD in Forestry (University of Canterbury).
Vega Xu
Small-scale plantation forests, optical satellite imagery, LiDAR, UAV
Vega Cong Xu is the WIDE Trust Lecturer in Geospatial Technologies and the co-director of the ‘Remote Sensing and Geospatial Analysis Research Group’ at the School of Forestry. She is interested in remote sensing applications in forestry and natural environment, through processing and analysing remote sensing data such as satellite imagery, LiDAR and UAV photogrammetry to classify forest types, assess forest growth, and monitor vegetation changes. She has recently been working on applying geospatial and remote sensing technologies to better describe New Zealand’s small-scale plantation forests.

Ning Ye
Optical satellite imagery, time series, LiDAR, machine learning, Google Earth Engine
Ning Ye is a postdoctoral researcher in Forestry at the University of Canterbury. She obtained a BSc degree in Geographical Information System from Wuhan University and an MSc degree in Geoinformation Science and Earth Observation from the University of Twente. For her PhD at the School of Forestry, her research focused on classifying New Zealand's native forests using optical satellite imagery. This research enabled accurate classification of the highly diverse native vegetation in New Zealand at a finer scale and at a lower cost. Currently, she is working on an NZDFI project that aims to use drone LiDAR data to generate a New Zealand-specific Eucalyptus biomass model.

Haotian (Joe) Zhao
Urban forestry, deep learning, remote sensing
Haotian (Joe) Zhao is a PhD candidate at the School of Forestry. His research is centered around the application of advanced artificial intelligence (AI) techniques to urban forestry monitoring. One of his current research projects involves the development of a convolutional neural network (CNN) for individual tree detection using aerial imagery. This project utilizes cutting-edge AI techniques, including self-supervised learning and synthetic data, to address the challenge of data scarcity and improve the training efficiency of the model. By leveraging these innovative techniques, it aims to significantly enhance the accuracy and generability of AI models in urban forest applications.

Robin Hartley
Forestry, remote sensing, proximal sensing, phenotyping, automation
Robin is currently a Masters student in the GIS and Remote Sensing Lab Group within the School of Forestry, University of Canterbury. He is working on research looking at deriving branch phenotypes from the point clouds of mobile laser scanners. Robin also works full time at Scion as a geospatial scientist in the Autonomous Systems team, where his research focuses on UAVs, proximal sensing, phenotyping and democratising technology for the forest industry. Robin has a BSc Hons in Geography and Environmental Management from the University of the West of England in the UK. He’s also a keen surfer and spends as much time at the beach as his three-year-old will allow!

David Pedley
Urban forestry, remote sensing, geospatial analysis, urban planning
I am currently a PhD student in the GIS and Remote Sensing Lab Group within the School of Forestry and am part of the University of Canterbury Geospatial Research Institute. I am working on research looking at the relationship between urban trees and housing intensification, with a focus on the loss of trees on private residential land. I received my previous degrees in law (LLB) and science (BSc in Biological Science and Geography) from the University of Canterbury and spent 11 years working as an environmental lawyer. I recently completed my Master of Landscape Architecture at Lincoln University.
