Dr. Abourahma’s interests are in the area of crystal engineering, which deals with designing and synthesizing functional solids using non-covalent interactions. The premise of crystal engineering is that the physical properties of a material can be altered by altering the solid state since physical properties are critically dependent on the chemical composition as well as the arrangement of the molecules in the solid state. Dr. Abourahma’s research more specifically centers around studying pharmaceutical cocrystals, compounds that consist of two or more components at least one of which is an active pharmaceutical ingredient and are held together by hydrogen bonding interactions.
