Emily Holt (PhD)

Welcome to my Stavros group webpage!

History

After graduating with my BSc in Maths from Warwick in 2016, I joined the group in May 2017 as an MSc project student from the Molecular Analytical Science Centre for Doctoral Training. More information about me, and links for more information on the doctoral training centre itself, can be found on my personal MAS CDT webpage.

My MSc project, in partnership with Lubrizol, was ten weeks in duration, during which time I studied the ultrafast photoprotection properties of the sunscreen filter octocrylene in solution and thin films. I thoroughly enjoyed my time with the group, so I'm back for my next challenge!

PhD Project

My PhD project, in conjuction with my industrial supervisor (Dr. Laurent Blasco, Lubrizol) will focus on the photodynamics of avobenzone (AB), a UV filter found in sunscreen that is known to be photounstable.

The first part of my project will involve solution phase experiments to determine how AB behaves when mixed with additional UV filters, and whether its stability is positively or negatively affected by the presence of these filters. During the next stage, emollients will be added to the mixture, to see whether these molecules have a detrimental impact upon the photoprotection properties of a sunscreen formulation, a so called "bottom-up" approach. Updates will be added here as the project progresses.

The main aims of my PhD are: to better understand the photochemical and photophysical mechanisms of a suncreen containing AB on a fundamental level to improve the safety and efficacy of sunscreen products, to advance the capabilities of our ultrafast setup to include temperature-controlled measurements and thin films, and to advocate our ultrafast technology for industrial use, particularly for cosmetics and personal care.
