I graduated in Physics at Padua University (Italy) in March 2000 with a thesis regarding Electron Paramagnetic Resonance of transient species. Since then I made lot of things but not Science. I was waiter first, I run a restaurant and a hotel as well later, also part time teacher in a high school. My readings span a large variety of fields such as Economy (The Road to serfdom of FRIEDRICH A. HAYEK is a recent one), Religion, Politics, Business Management, and others. That was probably not enough: I applied in Malcolm Levitt's group and now I am based in Southampton with a project concerning hyperpolarized singlet states.
Aim of the project
Nuclear singlet states are quantum spin states described to have much longer lifetimes than the characteristic relaxation time of longitudinal magnetization T1. In some cases, the nuclear singlet lifetime is as long as half an hour and even more. The group studies the structural and dynamic constraints a spin system must obey to exhibit long-lived nuclear spin order. We are exploring the concrete possibility to combine hyperpolarization techinques such dissolution DNP to singlet states so that to achieve hyperpolarized long living states. This could be of immense importance in fields like clinical imaging and the studies of the structures and dynamics of biomolecules.
The project will also involve in a later stage some MRI. In particular we would like to join MRI and (hyperpolarized) singlet states. For the time being I am trying to simulate some basics MRI pulse sequences using SpinDynamica (check 5 in References for further information).
