Name: Dr. Judith Angelstorf

Position: Research assistant, PhD student

Background and Interests

Judith Angelstorf holds a PhD in biology and has been working in the field of environmental analysis and ecotoxicology since 2007. Ms Angelstorf completed her studies at the Institute for Biogeochemistry and Marine Chemistry at the University of Hamburg. As part of her diploma thesis, she investigated the influence of environmental parameters on emissions of halogenated hydrocarbons by halophytes by determining flux rates and isotope ratios of the compounds. An internship at the 2nd Institute of Biogeochemistry in Hangzhou, China, enabled her to expand her knowledge of environmental analytical measurement methods.

From 2009 to 2013 Ms Angelstorf was in charge of sampling and ecotoxicological investigations of sediment and suspended matter samples in the diPol and Seitenstrukturen II projects in the Applied Aquatic Toxicology working group. In 2013, she completed her doctorate at the Hamburg Harburg University of Technology on the topic of “Effects of titanium dioxide nanoparticles on the nematode Caenorhabditis elegans”. The focus of the study was on the influence of simulated solar radiation on the toxicity of the photocatalytically active particles, as well as their influence on co-contaminants.
