We’re interested in how the world works on a nanoscale and we believe that some of the most fascinating phenomena occur on interfaces. Our research is focused on obtaining a fundamental understanding of the properties of, and processes occurring at interfaces. We aim to elucidate how liquids and soft matter interact with solid surfaces, and how they behave in nano-scale films or pores, among others. Our objective is to solve problems and advance the knowledge relevant to a range of applications including energy storage, nanofiltration, lubrication, adhesion, and nanomaterials like graphene.

Some examples:

  1. Future resources for the water and energy needs of our society, such as supercapacitors for energy storage and water desalination by nanofiltration membranes, rely significantly on solid-liquid interfacial properties. We have innovative ideas using graphene to improve nanofiltration membranes and energy storage…. Highly concentrated electrolytes like ionic liquids open up new opportunities to design energy storage systems with higher energy densities and power, and thereby, to make better use of our precious renewable energy resources.
  2. When two bodies are in contact and in relative motion, friction happens at the interface. A significant amount of energy in transport industry is lost due to friction, and new green and safe materials and lubricants are needed to reduce such energy loss and control friction. Even our body needs to maintain very low coefficients of frictions in our joints, eyes and oral tracks;  discovering new hydrogel-like biomaterials to replace  damaged biological tissues is another motivation for our search for questions and answers. We believe that our studies will inspire new avenues to craft biomaterials with improved functionality.
  3. The interfacial chemistry of minerals dictates many important phenomena and is quite complex. The precipitation and dissolution of CO2-binding carbonates participates in geomorphological processes of the Earth’s crust, biomineralization, contaminant capture, climate change and it may be even important in the evolution of earthquakes.

Three open PhD positions in the fields of:
