With more than 80% of our energy resources recovered from the subsurface environments which requires about 50 billion cubic meters of fresh water and contributes to more than 75% of global CO2 emissions, our grand societal challenge lies in meeting our growing demand for energy and resources while reducing environmental impact. Addressing these earth-scale challenges requires us to develop novel technologies to engineer targeted physico-chemical interactions in complex engineered and natural environments. Enabling emergent technologies for a sustainable earth requires us to advance the cross-scale science of fluid-solid interactions in complex and extreme environments. With this perspective, our research is directed towards applications that involve (i) engineering the natural environment for sustainable energy and resource recovery and (ii) designing novel chemical pathways for advancing low carbon and negative emissions technologies.

Efforts to manipulate and control materials at the nanoscale have taken center stage in research activities all over the world, motivated in part, by the realization that nanoscale materials often exhibit properties that are dramatically different from their microscale counterparts. In that respect polymer nanocomposites synthesized by adding nanoparticles such as nanoclays into the polymer matrix have attracted considerable attention in recent years. The goal is to develop lightweight composites with potentially superior mechanical, rheological, electrical, thermal and biomedical properties by taking advantage of the high surface area available in the nanoparticles and the accompanied synergistic effects with the polymer matrix.
While the world faces many seemingly insurmountable challenges, insuring access to affordable, reliable, sustainable energy for all its citizens is not only achievable, but of paramount importance to lifting the marginalized out of poverty and reversing climatic damage.
