About Hala

Hala Afifi graduated in Pharmaceutical Sciences with Honour from the Faculty of Pharmacy, Ain-shams University, Cairo, Egypt in 2001, where she was then employed as a Pharmaceutical chemistry instructor for 2 years afterwards.

Hala obtained her MSc in chemical research with distinction from the University of London (2006); her thesis involved the organic synthesis of haptens for polyclonal antibodies and the effect of solvent on antibodies kinetics.

Hala’s PhD project focused on the structural characterisation of biocompatible and biodegradable wormlike micelles using different techniques, including rheology, small-angle neutron scattering and Cryo-TEM. She investigated the encapsulation of pharmaceutical oils and drugs in the wormlike micelles and their effect on micellar phase behaviour. She also studied the association behaviour of both wormlike and spherical micelles with hydrophobically modified dextran.
