As a member of the Borehole Research Group, I contribute to the maintenance of the logging database of the Ocean Drilling Program (ODP) and now the Integrated Ocean Drilling Program (IODP). My responsibilities involve mostly the processing of acoustic logs and VSP data, and the integration and/or conversion of various data sets and formats to make them available to the scientific community. It also gives me the chance to sail on ODP and IODP cruises to collect new data.

In recent years, my research has been focused in the identification of gas hydrate by downhole acoustic logs. In particular, I have been trying to understand the nature of the interaction between gas hydrate and its host sediment which is responsible for the strong sonic attenuation that we were the first to identify and document in the Mallik wells, McKenzie Delta, Canada.
