About Me

Short Biography:

Gaby joined Imperial College in 2009. Prior to this she was a Senior Research Fellow in the ATI, University of Surrey (2004-2009). Since 1999, she has been with the University of Glasgow, initially working on a NASA project in the Device Modelling Group, and thereafter joining the Optoelectronics Research Group where she carried out theoretical and computational studies of advanced optoelectronic devices (active optical waveguides and VCSELs). In 2007 she was awarded a visiting professorship by the C.N.R.S. (France) and spent a period in 2007/2008 in the Laboratoire Pierre Aigrain at the Ecole Normale Supérieure, Paris. In 1997 she spent a six-month period in the Forum for Theoretical Sciences (Chulalongkorn University, Bangkok (Thailand) & International Centre for Theoretical Physics (ICTP), Trieste (Italy)) as a visiting professor with a fellowship awarded by the Thai Research Fund. Between 1991 and 1995 Gaby was a visiting researcher in the Institute of Acoustics (C.N.R.), Rome (Italy) with fellowship awarded by the Italian Ministry of Foreign Affairs.

Gaby received the M.Sc. degree in semiconductor physics from Sofia University (1983) and the Ph.D. degree in theoretical condensed matter physics (1997) from the Institute of Solid State Physics, BAS, Sofia (Bulgaria)
In 2001 she passed courses in Parallel Computing, Edinburgh Parallel Computing Centre, UK

Research interests:
Gaby’s research is essentially theoretical and computational. It consists of application of existing formalisms and development of novel theoretical and computational techniques to study the electronic structure, optical and vibrational properties of low-dimensional semiconductor structures (heterostructures, QWs, QDs, carbon nanotubes) and devices (MOSFETs, semiconductor microcavities (VCSELs)) exhibiting quantum effects. Gaby’s past studies have included predominantly condensed matter physics tools, such as quantum statistical methods (Feynman path-integral technique) for electronic band structure and optical spectra calculations in disordered heterostructures and quantum wells, phonon modes calculations of inhomogeneous elastic fractal membranes and transport phenomena in low-dimensional semiconductor systems, with particular reference to interfaces in device materials and electronic devices (MOSFETs). More recent studies employ methods of the quantum and nonlinear optics: ultrafast dynamics, numerical simulation of optoelectronic devices (nonlinear waveguides, VCSELs), optically-induced quantum coherence, quantum control in semiconductor micro- and nanostructures and nonlinear optical activity and magneto-chiral effect in single-walled carbon nanotubes (SWCNTs) in the coherent nonlinear regime.
Her research in recent years is focused on the theory and modelling of ultrafast light-matter interactions in quantum semiconductor nanostructures and devices, more specifically on development of novel dynamical Maxwell-pseudospin models of the nonlinear coherent semiconductor carrier and spin dynamics and demonstration of quantum coherent phenomena, e.g. Self-Induced Transparency in low-dimensional semiconductors, coherent spin control in QDs and coherent nonlinear optical response of single chiral carbon nanotubes. Special emphasis in Gaby’s research is the implementation of the Finite-Difference Time-Domain technique which enables numerical simulation of nanoelectronic- and optoelectronic devices in real space and time and the use of high-performance (parallel) computing. Gaby has developed a unique parallel code in multi-dimensions running on a variety of multiprocessor platforms, based on the Maxwell-pseudospin approach that has been thoroughly validated against experimental data and other theoretical methods.
Gaby’s current research is focused on the theory of quantum coherence phenomena in semiconductors, such as coherent optical spin manipulation in individual QDs, with applications in quantum computation.
Gaby is an editor of the book “Optical Generation and Control of Quantum Coherence in Semiconductor Nanostructures”(2010)
http://www.springer.com/physics/quantum+physics/book/978-3-642-12490-7 of the Springer series “Nanoscience &Technology”.
She is currently acting as a peer reviewer of EPSRC and US NSF research grant proposals.
