Come upstairs in the Roisin Dubh to discover a world inside ourselves! Learn how biosimulators can help us to understand better our body via the creation of anatomical models. Tonight, in particular, you have the chance to get to know more about the properties of your brain matter and to see everyting clearly now... We will also talk about photochromic lenses!
Science of Shades
Dr. Nitheen Kaperi Sanyal (Principal Investigator-TCD and Consultant R&D Product Development Scientist at Transitions Optical, Galway)
The technology behind photochromic lenses is based on the phenomenon of photochromism which is reversible transformation, promoted by light, between two chemical species having different absorption spectra. The photochemical process is associated with a unimolecular reaction, and if the photogenerated species absorbs in the visible region of the spectrum, a color change can be observed with key feature of this phenomenon being reversibility. The R&D continuously develops new style photochromic products and the focus of the talk would be on the new state of the art photochromic lens product.
Building bio-simulators for better medical devices
Dr Fiona Malone (Biomedical engineer and Research Fellow and Medical and Engineering Technologies at GMIT)
In medical device design, animal studies are often used to study and predict any patient risks associated with a device. However, this procedure can prove costly and time consuming. Biosimulators can give a high assurance of design efficacy prior to animal studies and can also be designed and manipulated to specific anatomical abnormalities and/or disease states, not always possible with animal studies. This talk will look at the biosimulator creation process from the translation of medical data into engineering data and finally into clinically endorsed best-in-class anatomical models.
The Mechanics of Brain
Prof. Michel Destrade (Professor in the School of Mathematics, Statistics and Applied Mathematics, NUI Galway)
An impact to the head causes brain matter to shake, deform, stretch, shear and twist. In reality, we have little idea of what is actually happening inside the skull. To make progress, we can use computer simulations to create an impact and look at its consequences. However, these simulations are as good, and as bad, as the model they are based on. Here we will see some of the techniques available to measure and model the mechanical properties of brain matter in an accurate and meaningful way. The conclusion is that brain matter is very (very) soft.
