Current research projects – Medical and Biomechanical Engineering

Development of functionally graded bioprinted structures.

bone-tolerance-thresholdThis project, in collaboration with Dr Peter Bush (School of Pharmacy and Biomolecular Sciences at the University of Brighton), Dr Nick Dowell, Professor Mara Cercignani (both from the Clinical Imaging Sciences Centre at the University of Sussex) involves the development of functionally graded bioprinted structures. Using our new state of the art 3D bioprinter, we’re able to produce geometrically complex, functionally graded biocompatible structures for surgical planning and implantation using multiple materials in the same build. These structures are based on scanned structures which have been segmented and converted into printable file formats. The image shown here is the result of a tolerance analysis I did of some replica bone samples were scanned, segmented and 3D printed in plaster. We’re luckily enough to have Ella, our PhD student working on this project since 2015.

Design of variable density structures for 3D printing and additive manufacturing

variable-density-internal-structuresIn collaboration with Dr Karina Rodriguez Echavarria (School of Computing, Engineering and Mathemaics at the University of Brighton), Dr Asla Sa (FGV/EMAp in Rio De Janeiro, Brazil) and Professor Vinícius Mello (Universidade Federal da Bahia in Brazil) this project involves the design of cellular and scaffold structures for use with 3D printing and additive manufacturing machines. Currently there are very few design tools available to develop such structures, and this project involves the development of computer aided design (CAD) tools to allow engineers and designers to design such structures. The image here shows a section view of two internal structures with variable density (produced by Professor Vinícius Mello).

 

Using 3D printing to make sensors

cell-block-bhavikI am also working with Dr Bhavik Patel and Dr Aidan Fagan-Murphy (School of Pharmacy and Biomolecular Sciences at the University of Brighton) to 3D print biosensors, to allow us to make bespoke sizes and shapes for useful sensors in the lab. The image here shows part of one of the drawings used to specify the cell block used in a variety of biosensors.


Using 3D printing to produce bespoke usable models in anatomy education

vertebra-modelBeing able to produce bespoke anatomical models for various body parts and organs is a great way to support anatomy education. This project with Dr Claire Smith (Brighton and Sussex Medical School) involves the scanning, segmentation, conversation and printing of  bespoke anatomical models to support the educational process. With so many anatomical and biological models now becoming available through initiatives like the NIH 3D print exchange (http://3dprint.nih.gov/), it’s really helping everyone to focus on being able to convert scan data into meshable, printable formats for bespoke FEA and 3D printing applications across the board. Shown here is a vertabra, scanned using a high resolution CT scanner and printed in ABS plastic.

Development of 3D printing processes to support orthopaedic surgical planning

thresholded-bonesThis project involves the development of processes to support orthopaedic planning. In collaboration with Dr Peter Bush (School of Pharmacy and Biomolecular Sciences at the University of Brighton), we’re looking at how we can produce useful orthopaedic tools, jigs and prototypes to help surgeons plan, practice and perform surgery as best they can. Shown here is a single bovine foot bone that’s been segmented using various settings to help understand the two the software can be used to differentiate between cartilage and bone. There are subtle, but noticeable differences between the models at the boundaries between the bone and the cartilage.

Current research projects – Ergonomics, human factors and user experience

Biomechanics of using computer mice

flex-ext-jigOne of our PhD students, Bashayer Alhay is currently working on a project to investigate the biomechanics and ergonomics of various computer mouse designs. This project is in collaboration with Dr Lucy Redhead (School of Health Professions at the University of Brighton) and Dr Martin Bailey (School of Sport and Service Management at the University of Brighton). Shown here is one of our rigs being used as a benchmark tool for some electrogoniometer and fastrak measurements (image courtesy of Bashayer Alhay).

Embracing the Gesture-Driven Interface: designing and evaluating air-based Interfaces

Our latest PhD student Tobias has recently joined us from the Federal University of Pelotas in Brazil. He is investigating the use of gesture-drive interfaces . This project is in collaboration with Dr Lyn Pemberton who is also in the School of Computing, Engineering and Mathematics.

Human factors issues in bicycle design and safety

I’m currently running a small research project with the University of Brighton Cycling Club and the Institute of Ergonomics to investigate the issues surrounding visibility in cycling. We’re also looking at the human factors and ergonomics associated with bicycles and their components, to try to understand the extent to which the bicycle design been optimised for human wellbeing and performance (the aim of human factors/ergonomics), and to look for ways to improve the designs to best meet these requirements. There are many companies who manufacture bicycle components and make impressive claims as to the benefits in terms of comfort and/or performance, but many of these claims are often unsupported with evidence (I should add here that there are also many that are supported by fantastic evidence!). I’m keen to find out more about the research and development that has been done on such products to see if we can help to support these claims publicly, or to investigate the real state of affairs in terms of product benefits and performance.

Current research projects – Sports and other engineering

Parametric modelling of mechanical behaviour of bicycle frames and components

vertical-compliance-bicycleMy current bicycle engineering research project has the aim of understanding and quantifying the influence of key parameters on the structural behaviour of the bicycle. Ultimately, we’re aiming to establish a set of design guidelines that can support engineers and designers in the design process. Starting with the frame itself, we’re looking at geometric parameters (including tube lengths and frame angles, tube butting profiles, tube thicknesses and sectional profiles, and tube curvatures/shapes) and material inputs for standard tube designs in steel, aluminium, titanium (available from Reynolds (UK), Columbus (Italy), Tange (Japan). The image here shows an early FE model using beam elements to simulate the frames vertical compliance with varying geometry. Of course there’s carbon too, but we want to start with the traditional materials (which are simpler to work with!) before we enter the world of composites. I’m also interested in the dynamic behaviour of bicycles, in particular the design and setup of suspension systems for mountain bikes. I’m currently establishing an international collaboration with Dr Jean-Marc Drouet of VélUS (Department of Mechanical Engineering, Université de Sherbrooke in Canada), Joachim Vanwalleghem (Department of materials science and engineering, University of Gent in Belgium) as well as Dr Steve Begg and Dr Dan Coren here at the University of Brighton.

Development of cricket bats with improved dynamic properties

This is definitely a hobby research project, but one close to my heart. The project involves modelling and measuring the dynamic responses of cricket bats with various blade and handle properties. I have a theory that might show a huge difference in dynamic performance – and no, it’s not carbon fibre handles, shorter blades or big heavy blades. I’m hopeful that the results will speak for themselves!

Development of bespoke Design Data Management (DDM) systems

This project came about as a result of my recent KTP project (which was awarded as outstanding by the Technology Strategy Board (TSB). In particular, the marvellous work done by Jugal, Erik and team highlighted the need for design teams, suppliers and subcontractors to have carefully considered design data systems to allow for free exchange of design data between them. This project involves the development of bespoke design data management systems for design teams.

Educational research projects

Flip learning in Engineering and Design

3d-visualisation-technical-drawing-blocksIn collaboration with Dr Bhavik Patel (School of Pharmacy and Biomolecular Sciences at the University of Brighton) and Dr Deshinder Singh Gill (also from School of Computing, Engineering and Mathematics, University of Brighton), this project involves experimenting with using the Flip method for teaching and learning. In particular, we’re looking into how this can be used across various subject areas and teaching modes, from pharmacy to engineering to design. The examples shown here are simple geometric shapes that can be used to support 3D visualisation and technical drawing exercises.
