Principal Investigators

Prof Christoph Wälti

Christoph is a Professor of Bionanotechnology and his research interests include the development of electronic (and other) biosensors – in particular for infection diagnostics with a focus on AMR (antimicrobial resistance) – and exploiting molecular self-assembly for applications such as molecular data storage. Christoph studied Physics at ETH Zürich, Switzerland, and received his PhD in 2000 for his work on the symmetry of the order parameter in the heavy-electron superconductor UBe13. In 2001 he was awarded a Swiss Marie-Curie Fellowship to work on the self-assembly of molecular complexes using DNA at the Cavendish Laboratory at the University of Cambridge. In 2004, I was awarded an EPSRC Advanced Research Fellowship and joined the University of Leeds where I set up the Bioelectronics Laboratory.

Dr Virginia Pensabene

Virginia is an Associate Professor of Electronics and Biomedical Engineering, and her research currently focuses on developing technologies for fertility treatments.
Virginia is committed to educating engineers, scientists, and the public on health risks related to lifestyle, environmental toxins, and regulatory gaps. Virginia graduated in Electronic Engineering at the Universita’ di Pisa in 2004 and then received a PhD in Humanoid Technologies from the Universita’ di Genova and the Italian Institute of Technology. Virignia held research positions at Waseda University in Tokyo and at Vanderbilt University. Virginia is now co-founder and CEO of IVFmicro ltd, a Spin off of the University of Leeds.

Dr Paolo Actis

Paolo is an Associate Professor in Bionanotechnology and after graduating in 2008 with a PhD from the Grenoble Institute of Technology (FR), Paolo spent 4 years in California working on his tan at NASA Ames (US) and UC Santa Cruz (US) before crossing the pond again to lose his tan at Imperial College London (UK). Paolo then spent two years at Bio Nano Consulting as a Consultant & Project Manager. Paolo loves gardening and cooking (I make the best Lasagna this side of the Channel) and I used to play beach volleyball, surf and practice Krav Maga (with very mediocre results). I am massive Juventus fan !

Postdoctoral Scholars

Dr Tim Luxton

Tim graduated from his PhD in 2023 from the University of Leeds, where he developed a novel approach for measuring small molecules, specifically beta-lactam antibiotics. His work now is focused on the analytical validation and commercialisation of his developed meropenem assay and underpinning technology, and the clinical adoption of therapeutic drug monitoring for antibiotics and other small molecule drugs.

Dr Chalmers Chi Cheng Chau

Chalmers earned a PhD in molecular and cellular biology from the University of Leeds working on single molecule analysis using solid-state nanopores and single cell manipulation with scanning probe microscopy. Chalmers work is now focused on developing innovating nanopore approaches for studying ribosome specialization as part of the Ribocode project. Chalmers enjoys bouldering and sponsoring guide dog puppies through Guide Dogs UK. He also enjoys visiting zoos, IKEA and cinemas. Penguins and giraffes are particularly fascinating to him – they are “giraffic”.

Dr Rosa Catania

Rosa earned her PhD from the School of Pharmacy at the University of Nottingham in 2018, where she developed carbohydrate recognition elements for drug delivery. She was subsequently awarded a two-year EPSRC Doctoral Prize Fellowship, expanding her research into new antimicrobial strategies. In 2020, she joined the University of Leeds as a Research Fellow, where she has developed expertise in membrane biophysics and bioengineering. She is currently working on an EPSRC PBIAA project focused on developing in vitro diagnostic assays and devices for penicillin therapeutic drug monitoring to tackle antimicrobial resistance.

Dr Parisa Noohi

Parisa graduated from Sharif University of Technology in 2023 with a PhD degree in biomedical engineering. She developed bioactive hydrogels for applications in tissue engineering and regenerative medicine, specifically regenerative endodontics. Her current work focuses on harnessing novel biomaterials to enhance in vitro modelling approaches, including organ-on-chips and organoids, in reproductive bioscience.

Dr Delanyo Kpeglo

Dela isa postdoctoral research fellow focusing on 3D cultures using microfluidics technology to develop organ-on-a-chip models of healthy and diseased tissues to understand biological mechanisms, aid in diagnostic methods, and facilitate the testing of new therapeutic strategies.

PhD Students

Zijing Wu

Zijing is a PhD candidate specializing in electronic and electrical engineering, focusing on microfluidic skin-on-chip technologies development.

Eren Akcay

Eren is pursuing a PhD focused on detecting antigen-specific T cells to assess the remaining immunity of patients for vaccination management. My research involves surface functionalisation to capture and analyse these cells in a microfluidic device, with the goal of improving immune monitoring strategies.

Henry Budds

Harry graduated in Biomedical Science from The University of Warwick in 2020 and Molecular Medicine from University of York in 2021. He then worked in a lung research lab at The University of Cambridge before starting a PhD in the MRC DiMeN DTP in October 2024. He is co-supervised by Dr Eric Hewitt & Professor Sheena Radford in the School of Molecular and Cellular Biology and Dr Paolo Actis in the School of Electronic and Electrical Engineering, building on an exciting collaboration to utilise nanoinjection as a tool to study alpha-synuclein amyloid toxicity inside neurons.

Gayathri Mohanan

Gayathri is a PhD student focusing on single molecule detection of proteins using DNA origami and nanopores. Her work focuses on developing novel technologies for small protein detection using nanotechnology.

Dylan Charnock

I studied electronics and computer engineering with an interest in signal processing. Following, I began my PhD with a focus on signal processing, statistics and machine learning pertinent to nanopore signals. I have a major dislike for sand.

Miguel Jimenez-Munoz

Miguel earned his degree in Biotechnology from Francisco de Vitoria University in Madrid, Spain. He completed his bachelor's dissertation at Mount Sinai Hospital in New York City, USA. Following this, he secured a position as an assistant researcher at the National Institute of Cardiovascular Research in Madrid, where he focused on targeted nanovaccination strategies using various nanomaterials. Miguel furthered his education with a Master of Research (MRes) in Nanomaterials from Imperial College London and a Master of Science (MSc) in Nanoscience, Materials and Processes from Universitat Rovira i Virgili. This extensive training equipped him with expertise in electrochemical sensors for malaria and SARS-CoV-2 diagnosis. Currently, Miguel is working on the development of electrochemical Random Access DNA memory.
