My research focuses on Organic Vapor Jet Printing (OVJP) of small molecular materials. This deposition technique enables solvent- and vacuum-free patterning of small molecular compounds on any substrate and any shape. Using OVJP we are able to access a unique surface morphologies in organic films with many promising applications, such as semiconductors, pharmaceuticals and food industries. Currently, I am working to develop models that predict the morphology of organic films grown by OVJP, evaluate thermophysical properties of small molecular compounds, optimize patterning resolution of small organic molecules used in organic semiconductor industry (organic light emitting diodes, organic this film transistors and organic photovoltaics). I’m also developing novel processing techniques for improvement of bioavailability of small molecular pharmaceuticals with poor aqueous solubility.
