We seek to build cell-like structures from the bottom-up to better understand the minimum components necessary for the emergence of life. Perspectives range from abiotic, origins of life to more biological reconstructions from primary components. Ultimately we envisage the creation of self replicating systems capable of Darwinian evolution.

Research directions
What is life? How does one build something they cannot define? As can be seen from such questions, the creation of cell-like structures in the laboratory is fraught with difficulties. However, the synthesis of a self replicating system is tractable and would lay the foundation for subsequent evolutionary experiments that could give rise to more complex and more life-like systems. It is towards this end that much of our research is directed.

Life is compartmentalized. While historically most of the biochemical research has been carried-out in dilute solutions, the physiologically relevant conditions are far from such laboratory experiments. Inside of small compartments, such as a vesicle or a live cell, protein concentrations, ionic strengths, viscosities, and enzymatic activities are quite different. Therefore, we are seeking to better characterize intravesicular molecular behavior through spectroscopic techniques.

Cellular compartments divide. From simple to complex life forms, cells are found that replicate through division mechanisms. While division without loss of entrapped material appears to be a difficult process, it can nonetheless be reduced to a surprisingly small number of parameters.

Cellular genomes replicate. Nucleic acids are the universal information storage molecules in cells, and so our early steps in the building of cell-like structures includes the compartmentalized reconstitution of isothermal genetic replication systems
