Current Research and Development Projects

Cryptochrome structure prediction
Most of the available crystal structures for cryptochrome proteins are incomplete, so I am trying to construct the missing part of Arabidopsis t. cryptochrome 1 by computational approaches.

Realistic spin chemical model for magnetoreception
So far the models used to investigate the radical pair-based mechanism utilized by migratory birds to sense the geomagnetic field have been somewhat artificial. I want to create as realistic a model as possible, and use it to evaluate the capabilities of the photoreceptor protein Cryptochrome to act as a compas sensor molecule. Read more on the Research Area page.

Spin Dynamics Software development
I am currently developing a spin dynamics software package, that I will use to create and test my spin chemical models for magnetoreception.

VIKING Development
I am also participating in development of VIKING, currently as designer of the user interface. Read more about VIKING here.
