About me

Kelsey attained his BSc in Forensic Science and Chemistry at the University of Toronto in Canada and his MSc in Forensic Science at King’s College London in the UK. He developed a strong interest in (eco)toxicology from his study. He conducted his master thesis in LC-MS analysis of the metabolites of growth hormone-releasing hormone synthetic analogue where he gained hands-on experience in instrumental analysis and laboratory testing. After his masters study, he joined the United Nations Environment Program internship program, working on the sub-programs of Ecosystem and Chemicals, Waste & Air quality.

Currently, Kelsey is employed as ESR at the Environmental Institute and enrolled in the PhD program at the Masaryk University. His research within PRORISK focuses on bridging chemical exposure with effect assessment. He is establishing the links between the exposures to large number of chemicals and the ecological status using statistical analysis. The outcomes of the research are expected to shed light on the prioritization of the pollutants for future regulatory monitoring and management.


Project title: Bridging chemical exposure with effect assessment
Objectives: Bridge chemical exposure with the effects at higher levels (ecological status, biological elements of quality) using target (>2400 chemicals; quantitative) and non-target (>40,000 chemicals; semi-quantitative) screening of environmental and biota samples; prioritize chemicals responsible for exceedance of the Effect-based Trigger Values.
Test the prioritisation at the local, regional and river basin scales for regulatory purposes.
Validate the novel concept with specific datasets (Joint Danube Survey 4; Joint Black Sea Survey).
Expected results: Establishment of links between the exposures to large number of chemicals and the ecological status (statistical analysis).
Prioritization of the pollutants for future regulatory monitoring and management purposes.
Place: Koš, Slovak Republic
