Research
I am working on problems related to fluid of various characteristic length scales. Here are examples of the research topics I am interested in.
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.
