Quote from Maddie Westenberg
My dream is to conduct novel bioengineering research at the NASA Ames Research Center in California. I hope to study the evolution of life in the universe and how synthetic biology can address issues related to the exploration of space and environmental problems on Earth.

A Stochastic Model of Cell-free Protein Synthesis Using the PURE System
Abstract: Synthetic cells consist of a lipid membrane and encapsulated biomolecules to emulate the processes of cellular life. Synthetic cells are used in biosynthesis, personalized medicine, and origin of life research. A major focus is protein production, widely accomplished by a technique developed in 2001 called the PURE system. By encapsulating a mixture of enzymes, DNA, and RNA, synthetic cells can be used to generate proteins. Computational models can predict the effects of each PURE system component and broaden the overall usage of the system. However, research is still in the early stages and often cannot account for stochastic variations in translation efficiency. We created a model in SBML (Systems Biology Markup Language) to predict levels of protein expression while also accounting for the stochastic nature of the PURE system. This model will provide valuable insight toward future computational efforts and help support the optimization and expansion of this technique.
