The Laboratory for Cellular Systems Modeling has been carrying out research to identify biological networks and its regulatory principles using computational, theoretical and experimental approaches. Our research interest is to identify and reconstruct biological regulatory circuits from experimentally observable data using computational and theoretical approaches to unveil the complexity of signal transduction networks, which determine cell fate in mammalian cells. By doing this, we are able to identify rules specified in immunological systems.
