Holly Siddique is a Lecturer in Analytical Chemistry. She joined Hertfordshire in 2024. She is the module lead for Drugs and Medicine in the 1st-year MPharm programme and teaches chemistry modules in levels 4-5 in the MPharm and BSc Pharmaceutical Science degree. She actively supports research activities and supervises undergraduate and postgraduate research projects.  

She obtained a BSc (Hons) in Pharmaceutical Science in 2015 and a PhD in Analytical Chemistry (Natural Products) in 2019 from the University of East London. Following her completion, she joined the trait diversity and function research team in 2020 at the Royal Botanic Garden, Kew, as a post-doctoral analytical chemist. 

In 2024, the Royal Society of Chemistry (RSC) awarded her Chartered Chemist (CChem) status. CChem is a peer-reviewed process that recognises the skills, knowledge, and professionalism within the chemical sciences. In 2025, she obtained a fellowship from the Higher Education Academy. 

Her research areas include extracting, isolating, and identifying secondary metabolites from natural sources using various chromatographic and spectroscopic techniques, with a focus on those effective against MRSA clinical strains, to tackle the global threat of antibacterial resistance. 

Her current research focuses on the identification and quantification of polyphenols from commercial bee propolis and investigates its effectiveness against bacterial strains
