Dr Gesa Staats de Yanes

Honorary Research Fellow, Neuro-Toxico-Pathologist, Stereologist, Microscopist

Brief profile

In her doctoral thesis in veterinary medicine Gesa Staats investigated organo-chlorine contamination and their distribution in the body in seals in context with the seal epidemics in the North Sea in 1989. After working in the WHO-centre for Veterinary Public Health in the School of Veterinary Medicine in Hannover, Germany, she went on to do a PhD and postdoc in the Developmental Toxico-Pathology Group in Liverpool University in collaboration with AstraZeneca. Stereology was used to study the effects of NMDA-receptor antagonists on the developing brain. She is currently studying the effect of nanoparticles on the development of neurodegenerative diseases. She is a member of the British Society of Toxicological Pathologists, the European Society of Teratology, the British Socienty of Neuroscience and the International Society of Stereology.

Research interests

Gesa Staats is interested in developmental toxicology and minimal changes in tissue morphology.

Currently stereology and histological methods are being used to investigate the effect of nanoparticles on neurodegenerative diseases.

In collaboration with ExploraNova stereological tools are being implemented in their stereology software package Mercator.
