Research in the Pozzo group centers on the development, measurement and control of self-assembly processes for soft materials over nanometer and micrometer scales. This manipulation of complex material structures results in novel properties that optimize their use in engineering applications.
High-Throughput Experimentation (HTE) and Data Science for Materials Design
Laboratory automation tools are being developed and used by the Pozzo laboratory to accelerate the pace of materials discovery. Robotic tools and efficient experimental screening methods allow us to execute experiments and to collect data with far increased efficiency. This enables the application of advanced analytical tools including supervised/unsupervised learning, dimensionality reduction and classification/sorting to extract additional value from data streams and to tackle increasingly complex problems with many interdependent factors.
We are broadly interested in the synthesis of emulsions and in understanding the fundamental science that controls their behavior for uses in targeted applications. For example, emulsion contrast agents can undergo a phase transition from liquid to vapor upon irradiation with light and/or ultrasound fields. The formation of this vapor cavity creates increased contrast for ultrasound imaging and can also be used for active thrombolysis, the mechanical destruction of an occlusion (clot) inside blood vessels.
Materials for Energy Storage and Conversion
High-throughput experiments and data science tools are also being used to develop the next generation of electrolytes for grid-scale electrochemical energy storage from earth-abundant materials. Moreover, the group is also developing new mechanisms to study and control the structure and properties of conjugated polymers and of blends of conjugated and engineering polymers to achieve functional materials with optimal mechanical, electrochemical and optical performance.
