I am a theoretician working in the field of attosecond physics. I study fundamental ultrafast electronic processes that occur in molecules and clusters following excitation and/or ionisation, for example by a laser pulse. These electronic transitions, such as Auger decay, interatomic (intermolecular) Coulombic decay (ICD) and others, are driven by electron-electron interaction and are the basic manifestation of the electron correlation in nature. They are of high practical importance for estimation and understanding of the radiation damage done by high-frequency radiation. My group is developing and using first principles many-electron theoretical methods to investigate the complex dynamics of the known electronic rearrangements and to predict new physical phenomena of this type. The ab initio computational method developed in my group recently, B-spline algebraic diagrammatic construction (ADC), allows us to look inside the radiative and non-radiative many-electron transitions in order to study the onset and the effect of quantum coherence on these phenomena.
I am also interested in bioinformatics, especially in the numerical simulations and software development for biomolecular mass spectrometry.
I was an EPSRC Research Fellow in 2010-2015, was appointed a Lecturer in 2011, a Senior Lecturer in 2014 and a Reader in Molecular Physics in 2018.
