First Name Helen Ann

I am currently a postdoctoral researcher in the Department of Energy and Process Energy within the Industrial Ecology Program. However, as of 2020, I'll be transitioning into industry and working in the area of sustainable aquaculture.

I hold a B.S. in Chemistry from Texas A&M University and an M.S. in Mechanical Engineering with a focus in Sustainable Technology from the Royal Institute of Technology. I received my PhD in Industrial Ecology from NTNU. I have previously worked for Ecoinvent, the Swiss Centre for Life Cycle Inventories. My work there primarily revolved around developing LCI methods for the chemicals sector.

Research Interests

Key words: Aquaculture; Material Flow Analysis; Socio-economic Analysis; Nutrients; Agriculture; Circular Bioeconomy

My research interests lie in analyzing the metabolism of nutrients and energy within the anthroposphere and, in particular, how these flows interact with and affect natural systems. This is with the aim of developing methods for reducing resource consumption, closing resource loops and reducing the environmental impacts of human activities.

My research is within the research area "Circular Economy and Resources" in the Industrial Ecology Programme on the following topics:

Phosphorus (P): P is a both a finite nutrient that is essential for plant production and a pollutant if accumulated in sensitive aquatic compartments. Because Norway does not have primary P resources of their own, it is essential to improve the management of P in order to ensure food security and reduce environmental impacts.

Food waste: Globally, food waste amounts to the loss of one third of all produced food. Large inefficiencies, such as this, have severe environmental implications as food production systems rely on a host of natural resources for operation. The unnecessary use of land, water, minerals and energy to produce wasted food exacerbates resource scarcity and, with expected population growth, could result in significant food security issues.

Aquaculture and fisheries: Because of the high dependency of the Norwegian aquaculture industry on imported feed ingredients, the projected drastic increase in production will likely affect resources on a global level. Supply chain impacts and resource demands, both domestically and abroad, need to be sufficiently understood in order to realize this growth and ensure its sustainability.

Biogas: In Norway, secondary biomass is seen as a potential renewable energy feedstock and, thus, a means to reduce domestic climate impacts. In order to produce this feedstock, however, there is an upstream demand for nutrients, such as scarce P. This means that an increase in biogas production will result in increased nutrient consumption. Relationships between energy and nutrients, such as the example above, are poorly understood. Therefore, my research focuses modeling these systems with an aim to avoid problem shifting and optimizing the use of both.

I am currently involved in the following projects:

- Mineral Intelligence Capacity Analysis (MICA); role: researcher

- Nutrients in a circular bioeconomy: Barriers and opportunities for mineral phosphorus independence in Norway (MIND-P); role: leader group and post doc

- Microbially Produced Raw Materials for Aquafeed (MIRA); role: researcher
