Asst Prof Abdulkadir C. Yucel(i) Fast frequency and time domain electromagnetic simulators with applications to the VLSI/microwave/terahertz circuits, biomedical, photonics, wireless channel characterization in tunnels, and analysis of inhomogeneous negative permittivity media. (ii) Uncertainty quantification for electromagnetic analysis on complex platforms
Assoc Prof Andrew James KrickerProf. Kricker's most significant research interest lies in the mathematical ramifications of current developments in mathematical and theoretical physics. To be precise, he is interested in the ramifications of certain developments in quantum field theory and quantum gravity in the fields of topology, algebra, and combinatorics. Prof. Kricker's particular speciality is in so-called "quantum topological invariants". These are invariants of knots, 3-manifolds, and various other low-dimensional topological structures, that arise from Topological Quantum Field Theories. More generally, he has a considerable general interest in the fields that surround this topic: knot theory, the theory of low-dimensional manifolds, Lie algebras, Hopf algebras, representation theory, homological algebra, algebraic combinatorics, and so on.

Prof Carlo SirtoriMy research activities are mostly dedicated to light and condensed matter interaction, with a special emphasis on semiconductor low dimensional-structures. The design and realisation of new devices based on the fundamental laws of quantum mechanics are always at the centre of my interests. My continuous interactive dialog with industrial partners has driven these investigations towards the matching of fundamental research with long-term technological needs. A clear example of the mixing between fundamental and applied is the quantum cascade (QC) laser where quantum engineering of artificial electronic and photonic potentials blend in with the realisation of optoelectronic devices. At present my main research interest are: - Quantum devices bases on the strong and ultra-strong light matter interaction - Superradiant devices - High frequency modulation of QC laser - THz QC lasers - Antenna coupled to micro-cavities detectors - Quantum phenomena in LC-circuit resonators
Assoc Prof Cesare SociOur research embraces several key areas of nanoelectronics and nanophotonics, including organic semiconductors and plasmonic materials, as well as new ideas on specialty optical fibers and “cognitive photonic networks”. We are particularly interested in fundamental properties of materials emerging from small dimensionality, large interface area, hybridization and artificial nanostructuring.

Asst Prof Chen GangDr Gang CHEN has been interested in probing the molecular recognition interactions responsible for RNA structures, stabilities, dynamics, and functions since 2001. He has worked on a variety of RNA structures including non-Watson-Crick base pairs (such as isoG-isoC, G-A, A-A, U-U, U-C, G-U, and A-C pairs), base triples, and pseudoknots. The triplex structures present in RNA pseudoknots inspired the current work on targeting RNA by dsRNA-binding chemically modified peptide nucleic acids (PNAs, see below), which show selective recognition of dsRNAs over ssRNAs and dsDNAs. 1.
