Research interests

My group works on the evolution of diversity in molluscs and other marine invertebrates. Morphology shapes how each species responds to environmental change, in the modern world and in the fossil record. We often focus on very strange body forms, like bivalved gastropods, or apparently conservative forms, like chitons. We use tomography (right) to visualise animal adaptations in 3D and understand the world from other organisms‘ points of view.

Understanding evolutionary radiations, survivorship, and the way animals respond to environmental change, require high resolution data from multiple disciplines, and the research infrastructure in museum collections. The work in my research group crosses genetics, morphology, anatomy, neurobiology, physiology, computational modelling, and experimental approaches, to understand species diversity.

Some of these are discussed in my recent book, What Species Mean: A User’s Guide to the Units of Biodiversity, published by CRC/Taylor & Francis in early 2018.

Molluscs are among nature’s greatest innovators, representing some of the most ancient and evolutionary successful animal radiations, with tremendous  diversity in morphology, behavior, and lifestyle. What molecular mechanisms and driving forces produce such great adaptability and diversity? How are novel genes and functions generated, and how do different reproductive strategies and selection affect genetic diversity (genomic heterozygosity), adaptations, and population genomics? These questions fascinate me, and I look forward to finding answers from the Book of Life by ATGC.

Research interests

Molluscan species have always fascinated me, from the gastropods that inhabit our gardens to the remarkably intelligent and agile cephalopods. The vast array of body morphologies within this group has evolved to suit various marine, freshwater, and terrestrial environments. Delving into their world, one can encounter a broad range of creatures, such as bivalved gastropods, tubular bivalves, worm snails, and numerous other peculiarities.

It is precisely due to this diversity that my primary passion lies in studying the anatomical adaptations of these remarkable organisms. To explore their intricacies, I employ cutting-edge techniques such as 3D reconstruction based on histology and tomography, along with the traditional method of gross dissection.

Research Interests

 The focus of my research is the phylogeny, biogeography, palaeontology, taxonomy and ecology of terrestrial microgastropods, and especially those belonging to the Carychiidae and Hypselostomatidae. My work emphasises an integrative taxonomic approach including CT and SEM investigation of shells, molecular analyses and histology. Ecological investigation delves into their superficial subterranean and subterranean habitats. A large scale revision of the ellobiid family Carychiidae is in progress.
