# Short Bio

I am currently working for Skidmore Owing and Merill as an architect since August 2015.
I'm an architect, especially a geometry/scripting expert at work, but at the same time an engineer in research.
I've been working as a postdoc researcher for 2 years in Igarashi Design Interface Project (JST/ERATO), computer graphics and design interface research group, and then for one year back in the University of Tokyo.
I received a PhD from the University of Tokyo in March, 2012, for my research about computational form finding and Dynamic Relaxation method.
I obtained a B.S from the school of Architecture, the University of Tokyo in March, 2007.

I'm interested in the relation between geometry and structural mechanics that is independent of building materials.

# Projects

### King Ghidorah

Nurbs-based form-finding of shell structures has been reinitiaited. NURBS-force diagram is the key.

### Mothra

A computational framework for self-supporting surfaces, accepted and presented by/at SIGGRAPH 2015.

### Sprout

To make curves and surfaces 3d-printable

### geodesicFractal

A simple algorithm to generate geodesics and its application to architectural design

### Ricecooker (Suspended)

A set of custom components of Grasshopper that supports computational mechanics.

### Tensors, static Mechanics, and differential geometry (Japanese only but slowly translated to English.)

Remind that there are two types of multiplications between vectors; row vector $\times$ column vector = scalar, and column vector $\times$ row vector = matrix.
The former is called inner product. The latter is called…, there is no name.
The good start point of learning tensors is to find out the name of this product.
