Planetary atmosphere
The governing equations for planetary atmospheres have already almost established. However, the dynamics of large-scale flows in planetary atmospheres are the results of very complicated interactions between many factors, and even the mechanisms of simple and typical flow dynamics are not necessarily clear. I am especially interested in the emergence and the development of large-scale patterns in two-dimensional flows on a rotating sphere. Here I perform large-scale numerical simulations, and also use some analytical strategies.

Flow around diatoms
Diatoms have a silica shell with regularly arranged micrometre-sized pores. To investigate how the presence of these pores affects diatoms, I am numerically investigating the flow around the diatom, making various assumptions about pore size, density and diatom shape. This is a collaborative work with diatom experts.

Bioinformatics on magnetite teeth
Chitons possess teeth made of magnetite, which exhibits greater wear resistance than zirconia. Whilst such materials are highly useful, human technology can only produce them under conditions of extreme high sound and extreme high pressure. In collaboration with chiton specialists, we are conducting genetic analysis to investigate the proteins involved in iron deposition on the cusps of the radular teeth of chitons.
