Dragosavac's research expertise lies in the broad field of advanced particulate manufacturing, with a focus on manufacturing particulate material using the dispersion route in which dispersed liquid drops are polymerised as a way of tailoring the properties of the resulting material using novel operating techniques.

She has established a national and increasingly an international reputation specifically in:

• Application of a new type of microfiltration membrane and new techniques for generating the shear on the membrane surface providing the possibility to generate larger droplets without risk of droplet breakage.
• Understanding at a fundamental level the factors that control particle size made using such techniques.
• Continuous droplet production and, therefore, continuous particle production using a novel membrane emulsification system. This type of system is an ideal starting-point for continuous particle production and it may be adapted to many different types of particles.
• Control of internal structure and encapsulation of shear and temperature sensitive compounds.
