Robert Johnson

Robert Johnson is an Associate Professor at the School of Chemistry, University College Dublin, specializing in electrochemistry and nanoscale sensing. His interdisciplinary research bridges fundamental studies of ion transport phenomena with applied developments in food safety, drug safety, and medical diagnostics. He leads projects funded by grants totaling circa €1 million over three years, including initiatives for early pathogen detection in food production and rapid identification of antimicrobial-resistant hospital pathogens like MRSA. His group's work leverages finite element modeling and experimental approaches to optimize nanopore-based sensors under low-electrolyte conditions.

• PhD, University of Southampton (2011)
• MChem, University of Southampton

Robert's research focuses on nanoelectrochemical systems, particularly conical nanopores and carbon electrodes. Key areas include ion current rectification, piezoelectric-plasmonic sensors, and chiral separation technology. His team's innovations in nanopore functionalization and biomimetic transport channels address challenges in pharmaceutical analysis, environmental monitoring, and infectious disease detection.

Recent publications highlight advancements in nanoscale sensor design (2025), including enantiomeric analysis and trace metal detection. Collaborative studies on finite element modeling and biomimetic nanochannels demonstrate his group's technical rigor and interdisciplinary impact.

Scientific contributions include:

• Marie Curie Fellowship (2013-2016)
• EPSRC Doctoral Prize Fellowship (2011-2012)
• Fellow of the Higher Education Academy (FHEA)
• Royal Society of Chemistry membership
• International Society of Electrochemistry membership

As a dedicated educator, Robert teaches electrochemistry and thermodynamics at UCD. Previously at the University of Lincoln, he developed physical chemistry curricula and achieved Royal Society of Chemistry accreditation for undergraduate programs. His research supervision includes multiple PhD students, and he actively engages in institutional committees like the Teaching & Learning Committee and College Timetable Committee.
