Trained as a landscape architect and building architect, Catherine’s research examines the materiality and performance of waste landscapes through exploratory methods in design research and practice. Her work has ranged in scale from large bio-cultural and sacred indigenous landscapes, to site design and architectural work, to furniture design and materials research. Through her design work, research, teaching and engagement, she explores ways of creating multiplicity within a single entity, space, building or site to form greater efficiencies and performative capabilities in design. Since 2014, Catherine has developed her design research—landscape lifecycles—as a holistic approach that synthesizes multiple programs, forming hybrid assemblages in the transformation of waste landscapes and materials. She uses landscape lifecycles as a framework for investigating the performance, visibility, citizenships, emotions and injustices of waste materials and landscapes. Since 2014, Catherine has developed her design research, landscape lifecycles, a holistic approach to transforming waste conditions. Her framework applies a material lifecycles lens to the inventory, analysis, and design of waste landscapes. This approach broadens typical definitions of inputs and outputs in lifecycle assessments to emphasize waste relations: the human, more-than-human, and perceptual and spatial dimensions of waste. Through landscape lifecycles, she investigates these relations by illuminating the performance, visibility, citizenships, emotions, attitudes, and injustices of waste materials and landscapes.
