Dr Vanessa Arranz Martinez PhD

Lecturer in Zoology and Ecology

School of Natural Sciences

Interested in applying genetic/genomic tools for understanding the dynamics of marine systems and conserving its precious life. My research expertise is in molecular ecology to disentangle the ecology and distributions of benthic invertebrates. From single-species studies, such as ascidians, molluscs and crustaceans to broader multiple-species views for assessing the patterns and processes driving the genetic connectivity among populations.
Recently immerse in the amazing and fast-growing genomics field, using Next Generation Sequencing (NGS) technologies and bioinformatics in various projects including environmental DNA metabarcoding and whole-genome sequencing (WGS) applied to kelp forests and coral reef ecosystems.
