Current research projects

Nucleation of ice and gas hydrates: Clathrate hydrates (gas hydrates) are ice-like crystalline solids in which small “guest” molecules are incorporated inside the hydrogen-bonded network of water. Gas hydrates are very similar to ice in some ways – one of the 18 known phases of ice has in fact been made by degassing the guest out of a gas hydrate. We have been systematically investigating the nucleation of ice and of gas hydrates.
