Reconstruction of CT images of the Antikythera Mechanism

The Antikythera Mechanism is a 2000 year old, ancient greek analogue computer with complex gearing. Originally made of bronze, it had corroded and calcified due to being under water for near two millennia. X-rays were capable of penetrating this calcium matter and revealed the bronze structure within! Unfortunately, a very important image dataset turned out to be corrupted...


Analysis of Brain Connectomes in Alzheimers Disease

Alzheimer's disease is described as a disconnection syndrome, where symptoms occur as a result of neuronal disconnection.  The white matter of our brain comprises of long distance neuronal connections. Combining different modes of MRI, we can create mathematical networks of the brain to see how different parts of the brain are connected and how it changes with disease progression...
