1. Theoretical understanding of the affect of flame dynamics on outwardly propagating flames with non-unity Lewis number.
2. Experimental determination of the influence of non-equidiffusion on the transition from spark kernel to freely propagating flame.
3. Experimental measurement of laminar flame speeds at elevated pressures with an emphasis on high molecular weight hydrocarbon fuels.

At Tsinghua University in Beijing, China, Andrew conducted experimental research during the Summer of 2009. The aim of the research was to design an experimental method of doping titanium dioxide nanoparticles, generated by stagnation flame synthesis, with metal ions. These nanoparticles are used as photocatalysts for water purification, among many other uses. Doping the particles with metal ions shifts the absorption spectrum towards the visible light spectrum, allowing catalysis reactions to be achieved using visible light.

At the University of Virginia, Andrew conduced experiments to determine how porosity affects the mass burning rate of heterogeneous combustion reactions. The two main fuels under consideration were magnesium and carbon which oxidized in carbon dioxide and oxygen enriched air respectively. Experiments were conducted in microgravity on board NASA's KC-135 aircraft.
