Research
interest

I have always been deeply interested in natural history, especially molluscs. The field work during my geology study took me to different parts of Spain where I collected terrestrial snails and discovered the impact of geology and climate on their distribution.

My geogical studies and thesis focused on the stratigraphy and depositional history of the Devonian and early Carboniferous of  the Cantabrian mountains (NW Spain), in which I used conodonts as indicator for age.

I became an active member of the Nederlandse Malacologische Vereniging and the Werkgroep voor Tertiaire en Kwartaire Geologie studying NW European faunas: from the tropical faunas in the Eocene of the Paris Basin to the temporary outcrops with Holocene faunas and recent ones.

topics

Working for Sarawak Shell Berhad I lived six years in Sarawak (Malaysia) during which I sampled and studied local Miocene to present-day faunas and had an opportunity to travel extensively through the region. The depositional environments in the region and their faunas have undergone many changes. Especially the large changes during the Holocene sealevel rise are remarkable. There is sufficient material for many years of further study. I am keen to cooperate with specialists on specific mollusc groups.
