Evolving more efficient digital circuits by allowing circuit layout evolution and multi-objective fitness [PDF]
, 1999 We use evolutionary search to design combinational logic circuits. The technique is based on evolving the functionality and connectivity of a rectangular array of logic cells whose dimension is defined by the circuit layout.

Genetic control of active neural circuits [PDF]
Frontiers in Molecular Neuroscience, 2009 The use of molecular tools to study the neurobiology of complex behaviors has been hampered by an inability to target the desired changes to relevant groups of neurons. Specific memories and specific sensory representations are sparsely encoded by a small fraction of neurons embedded in a sea of morphologically and functionally similar cells.
