Alex's research is focused on making medical tests that are stable in a wide range of conditions, for a wide range of diseases, all for less than a US dollar.
Alex engages the public with his research and scientific topics of interest on a national and local level.
"The passion for what he does was apparent and hopefully very inspiring to students"
Feedback for Alex at a Public Engagement event
Alex is a WIE foundation fellow, WIHEA alumni fellow and organic chemist with a focus on carbohydrate chemistry deployed on polymer and nanoparticle scaffolds. His work is used in the design of protein-free medical diagnostic devices. He is also a trained XPS user and teaches lab-focussed spectroscopy in undergraduate workshops and labs. He was awarded his Fellowship of the Higher Education Academy, MRSC and MRSB as a PhD student. Alongside his research, Alex is a Student Representative with a strong focus on removing educational barriers before and at university. Alex co-chairs, alongside Dr Bo Kelestyn, a group researching issues around diversity in STEM - specifically focused on how to decolonise STEM teaching and support women in STEM. Through this work Alex has supported and written for the Diversity Book Club initiative.
Alex enjoys communicating Science to all ages and is especially passionate about engaging students from Widening Participation (WP) and disadvantaged backgrounds.

Alex grew up in Essex, attending Westcliff High School for Boys for his GCSEs and A-Levels (Biology, Chemistry, Physics and History). He recieved his first class undergraduate masters degree in Chemical Biology from the University of Warwick Department of Chemistry. His final masters year thesis focused on glycosylation systems in prokaryotes as homologues of eukaryotes, under the supervision of Dr. M. Tosin. This work involved structural and functional studies utilising site-directed mutagenesis and activity assays.
Alex began his PhD under the supervision of Prof. M. Gibson in 2017 with industrial collaborators Iceni Diagnostics. The PhD is funded by Iceni Diagnostics and the BBRSC as an MIBTP iCase studentship and split between the Department of Chemistry and School of Life Sciences.
Since October 2017, Alex has been a member of the Postgraduate Student Staff Liason Committee for Chemistry and an MIBTP student representative for the University of Warwick iCase programme. In November 2017, Alex became the Postgraduate Research Representative for the Faculty of Science at the Univeristy of Warwick and was elected in March 2018 to represent the newly formed Faculty of Science, Engineering and Medicine. He was re-elected in 2019 and 2020.
Alex has a particular interest in improving student mental health, encouraging faculty outreach and raising the profile of teaching. His recent work has seen the introduction of a robust pastoral system for all PhD/PGR students and the passing of maternity/paternity leave for all funded and part-funded PhD students.
Alex has been made a Fellow of the Higher Education Academy and Warwick International Higher Education Academy (WIHEA) for his contributions to teaching, learning and the student experience. WIHEA is an academy of educators engaged in developing high quality learning and teaching at the University of Warwick. Alex has also been awarded a Warwick Institute of Engagement (WIE) Foundation Fellowship for his work in outreach and public engagement.
The development of glycan-based nanoparticles and lateral flow platforms for point of care diagnostics, and the synthesis of novel small molecules and sugars. He is also trained in the use of x-ray photoelectron spectroscopy (XPS).
Alex has undertaken a three month mini-project (January-March, 2018) at the University of Birmingham in the research group of Dr. F. Fernandez-Trillo. The project focused on producing glycopolymers for lectin agglutiniation studies.
During the UK COVID-19 lockdown (March 2020 to July 2020) Alex's research was applied to tackling the problems of COVID-19 diagnosis. By applying his research, Alex and other key workers in the Gibson Group (and colleagues in Physics, the Medical School and Iceni Diagnostics) were able to prove that the proteins on the SARS-COV-2 coronavirus could be sensed in a rapid lateral flow device. This was the first published lateral flow test to use only carbohydrates ("antibody-free") as sensing units.

Alex is a named inventor on a patent related to the COVID-19 rapid diagnostic work - Interested parties should direct their correspondence to Prof. Gibson.
The group's work producing a rapid diagnostic for COVID-19 ("coronavirus") has attracted media interest from the BBC and other media outlets. Prof. Gibson and Alex were interviewed.
Video from BBC Midlands Today evening and late news (26/6/20)
Alex presents his research and topics of interest to a wide audience for both the University of Warwick and at a National-level for organisations such as The Training Partnership.
Alex enjoys speaking on a variety of topics in Chemistry and the Life Sciences, he has a particular interest in drug/diagnostic development and design. He is passionate about showing that Chemistry impacts on all aspects of modern life and that Chemistry is a modern world-changing subject for all. Some examples of talks he has given are listed below;
- Lateral Flow Tests - Why Chemistry is more than just Chemicals - Alex presented this talk for The Training Partnership, Chemistry in Action 2021 events. His interactive and interdisciplinary talk focused on the health inequalities of the COVID-19 pandemic, specifically diagnostic inequalities, and explored if glycopolymer-based systems might be the answer. He presented at three events in London, Manchester and Warwick to >2,000 A-level students. Some feedback from the events is below;
"The passion for what he does was apparent and hopefully very inspiring to students""Very fun and I liked how interactive it was. The parts about health inequality was really eye opening.""Excellent synthesis of biology and chemistry. The juxtaposition of LFTs to pregnancy tests was a good comparison tool"Feedback from TTP Participants for Alex's talk
Chemicals, Cocktails and Creativity – from molecules to masterpieces ("Creative Reactions") - One of three Pint of Sciences 2021 events from the University of Warwick as part of City of Culture Coventry 2021 and the University's Resonate Festival. Alex proposed, designed and hosted the interdisciplinary session as a panel discussion between experts from Chemistry, the School of Life Sciences, School of Liberal Arts and the NHS. The topic of the session was the influence chemicals found in nature (caffeine, opiates, cannabis and psilocybin, and their synthetic derivatives) have had on biology, medicine, art and culture.
"@warwickengages have put on a cracking #PintOfScience talk this evening, somehow combining cocktails, science and history in a brilliant way"Feedback from viewer on Twitter
- When Medicines Become Drugs - National Pint of Science 2020 Speaker for "Cuppa Science" (Pint of Science during the COVID-19 UK lockdown) run by the University of Hull and presented by Phil Bell-Young (@Philby91). Marty Jopson was the other guest speaker (@martyjopson)
This talk explored the small chemical differences that separate medicines from drugs, and how these differences turn chemicals from those that heal to those that harm

The talk was later updated and repeated at NerdNite in 2021.
- Naughty or Nice Chemistry - Warwick Christmas Lectures 2019, for over 1000 primary school children
This lecture looked at what makes certain chemicals "naughty" or "nice" using lots of demonstrations and audience participation
Highlights from the Christmas Lecture
- When Medicines become Drugs - ACORNS Conference 2019 & 2021 run by Warwick ChemSoc for around 300 A-level students (2021 was virtual)
