About me

Susan completed her BED in Biology and Chemistry on the effects of endocrine-disrupting chemicals on the reproduction and health outcomes of Oreochromis spp at Maseno University, Kenya. Her MSc was in Conservation Biology on habitat use and ecological carrying capacity for the Eastern black rhinoceros.

Since graduation, Susan worked as a conservation biologist and data analyst with core experience and skills in ecology, monitoring data analysis, data management, and ecosystem impact assessment. For instance, she worked as a data manager on the impacts of air quality (PM2.5) on human health at GEOHealth Eastern African Hub -Kenya.

She is enrolled as a Ph.D. student in the Department of Technology, Management and Economics under the Quantitative Sustainability Assessment group at the Technical University of Denmark (DTU). During her study, she will focus on 1). central aspects of ecological exposure and related ecotoxicological effects of chemical emissions on ecosystem health, and develop harmonized and advanced computational methods to assess ecotoxicological impacts and related damages on genetic and functional species diversity and 2). developing an operational quantification framework to translate ecotoxicity impacts into damages on ecosystem functioning and service provision, for application in life cycle impact assessment and chemical substitution.

The Ph.D. project “Integrated risk assessment: from exposure through AOPs to ecosystem services” will contribute to research within the fields of computational ecotoxicity assessment and ecological modeling. Proposed methods will support the evaluation of chemicals emitted along the product life cycles in terms of ecological exposure and related effects on aquatic ecosystems, also guiding reductions in chemical pressure on aquatic environments and water quality.

Project

Project title: Integrated risk assessment: from exposure through AOPs to ecosystem services
Objectives:

To translate ecotoxicological effects from chemical exposure via different AOPs into damages on ecosystems expressed in measures of genetic diversity.
To link ecosystem damages to ecosystem functions and ecosystem services related damages expressed in measures of functional diversity.

Expected results:

Set of consistent metrics relating distinct ecotoxicological effects to damage on genetic diversity (i.e. species loss) at the level of ecosystems.
Quantified comparative damage factors differentiated according to species groups and/or groups of MOAs and/or groups of AOPs.
Approach for systematically linking genetic species diversity to ecosystem functions and services.
Damage factors for functional diversity differentiated according to ecosystem functions and services groups and/or species groups fulfilling similar/same functions or ecosystem services.
