I completed my PhD at McGill University (Chemistry) where I studied nanopatterned surfaces made using self-assembling block copolymer films in the Lennox lab. In 2005 I was granted an FQRNT (Quebec) postdoctoral fellowship to study the interactions of thermotropic liquid crystals with biological lipids and gold nanoparticles at the University of Wisconsin-Madison (Chemical and Biological Engineering) in the Abbott lab until starting at Mount Allison in July 2007. 

My research in interfacial nanopatterning is rooted in experimental physical chemistry, surface and interface chemistry, and nanoscience.

Research interests

Research in the Meli lab centres on the fabrication and characterisation of nanostructured films formed at interfaces.  Primarily, we are interested in understanding and influencing the self-assembly of nanoparticles into monolayer films at air-water and oil-water interfaces.  Achieving control over nanoparticle spacing and organization within films would have exciting consequences in many applications, including sensors, surface enhanced Raman spectroscopy, nano-photonics and electronics.  Generally, projects in the Meli fall within two broad themes:

1) Nanoparticle self-assembly at the air/water interface:  these projects aim to manipulate the self-assembly by making systematic changes to the nanoparticle-nanoparticle interactions (via core size, ligand functionality and phase state, the addition of additional components, and temperature).

2) Nanoparticle self-assembly at oil/water interfaces: these projects aim to manipulate the self-assembly by making systematic changes to the interfacial properties (via use of different oils, including anisotropic oils such as liquid crystals).
