Dr Lennon is a lecturer in organic chemistry with research interests in stereoselective organic synthesis using green and sustainable methods. She joined WIT in 2006 and is a programme leader of the BSc(Hons) in Pharmaceutical Science. She lectures in organic chemistry, biocatalysis and advanced spectroscopic characterisation at both undergraduate and postgraduate level with a strong focus on embedding research into her teaching and the undergraduate curriculum. She has organised seminars and information events for students, along with undergraduate conference events as part of the SURE Network.

Dr Lennon graduated from University of Limerick, with a Bachelor of Science in Industrial Chemistry and completed  PhD studies at University College Dublin in Organic Chemistry, specialising in the area of stereoselective organic synthesis.  Following her PhD she joined University of Edinburgh as a post-doctoral researcher in supramolecular chemistry and worked as a Development Chemist in the Pharmaceutical Industry.

Dr Lennon is a founding member of the PMBRC and to date has graduated 3 PhD students, with 5 research students currently under her supervision. Current research projects span biocatalysis, continuous processing, cascade reactions and novel anti-microbial development

Dr Lennon research interests lie in synthetic organic chemistry with the aim of designing novel green and sustainable regio- and stereoselective processes of pharmaceutical relevance.  More specifically areas of interest include the development of novel organocatalysts based on molecular recognition motifs, biotransformations using hydrolase enzymes and flow chemistry. She also has an interest in NMR spectroscopy and its applications. She is a member of the PMBRC (Pharmaceutical and Molecular Biotechnology Research Group) at WIT.

Dr Lennon lectures in organic chemistry, biocatalysis and advanced spectroscopic characterisation at both undergraduate and postgraduate level. She is programme leader for the BSc (Hons) in Pharmaceutical Science Year 4 and has also acted as External Examiner for programmes outside of WIT. She is a committee member of the Science Undergraduate Research Experience (SURE) Network which aims to enhace practise in undegraduate research, embedding this at both early and late years of the curriculum, and was Co-Chair of the National SURE conference organising committee in 2021 and 2022. She was a member of the SURE Covid-19 rapid response curriculum committee in 2020-2021. Dr Lennon was the recipient of the WIT 2021 Teaching Excellence Award and received a National Forum Digital Badge in Universal Design for Teaching & Learning in 2022.
