The project is devoted to the investigation of optical and magnetic properties of selected organic molecules. More precisely, computations will be carried out using state of art approaches to determine:
(i) the absorption and luminescence of molecules consisting of aromatic rings and a variety of other
side groups; and
Absorption and luminescence of marker molecules are routinely used to image biological structures. Moreover, both optical and magnetic properties are exploited to deliver drugs or heat to specific locations of cells and biological tissues. Absorption of microwaves by localised spins, for instance, may be used to burn cells, provided the spin-carrying molecules selectively bind to cancer tissue.
The project is supplemented by experimental activity carried out at UCD, and developed in collaboration with scientists at the Drug Discovery Department of the Italian Institute of Technology in Genoa, Italy.
The Biophysical Laboratory of the Centre for Physics in Health and Medicine at UCD Physics invites applications for PhD students supported through, e.g., Irish Research Council or UCD School of Physics SIRAT fellowships. The activity in the Laboratory includes experimental as well as computational approaches, and spans different subjects of interest for both basic research and applications. Topics include:

Many astrophysical sources, across a wide range of scales, contain variable relativistic outflows that are sites of non-thermal particle acceleration and emission. Examples include Blazars, which are compact active galaxies that emit knots of radio emitting plasma, and microquasars, which are similar to Blazars in many respects but are on stellar scales with a compact object and a companion star. These sources are powered by a central engine (either a black hole or a neutron star) that produces a relativistic jet whose energy is dissipated through its interaction with the external medium. There is a well developed theory of particle acceleration at these relativistic shock fronts, albeit in the steady state. What is less well understood is the transport and acceleration of non-thermal particles in the highly variable, relativistic outflow emitted by the central engine. The aim of this research project is to study the effect of variable, relativistic plasma flows on particle acceleration. Plasma waves imbedded in the flow scatter non-thermal particles between different comoving inertial frames. This will result in a form of Fermi acceleration, but not one that has previously been studied, for particles on a converging and evolving relativistic flow. The objective and central research question is to model this effect and to compare it to the observations of variability in a range of transient relativistic sources.

Discoveries in physics come through testing theories to breaking point. The Standard Model has given us an excellent description of the electroweak force, and investigating this theory in depth led to the discovery of the Higgs Boson. To see what new physics lies beyond the Standard Model, we must test it with the highest precision possible. At the LHC, the most precise tests of the Standard Model occur at the LHCb experiment where the W and Z boson cross-sections have been measured to sub-1% precision at 7 and 8 TeV. In 2015, the LHC increased its energy to 13 TeV and asks if the Standard Model still holds at the highest energies yet achieved, or whether new physics (like supersymmetry) subtly changes the observed results.
In this Ph.D. project the student will go to CERN, collect data on the LHCb experiment and isolate samples of events in which the W and Z boson decay to leptons. The efficiency and purity of this sample will be determined from the data and the differential cross-section for W and Z bosons determined as a function of transverse momentum and rapidity. The results will be compared to theory and any deviations investigated in terms of the modelling of the quarks and gluons in the proton, or in terms of new physics.
Supervisor: Prof. Ronan McNulty
The strong force is mediated by coloured gluons so interactions at the LHC usually produce hundreds of hadrons. However, colourless propagators (e.g. Pomerons) also exist in QCD and interactions via two Pomerons result in a very unusual experimental signature at the LHC of just a very few particles (Central Exclusive Production). Studying these tells us about the fundamental nature of QCD, allows a determination of the gluon content of the proton, and is a mechanism to discover exotic particles like tetraquarks and glueballs.
In this Ph.D. project the student will go to CERN, collect data on the LHCb experiment and analyse it to obtain a sample of Central Exclusive Events. Signals for known resonances (Jpsi, rho, f2) will be found and their cross-sections determined. Then searches will be made for unknown resonances whose observation would be evidence for new tetraquark states, glueballs, or new physics.
Supervisor: Dr. Emma Sokell
The aim of this project is to research the efficacy of non-traditional approaches to undergraduate (primarily laboratory) physics courses. The project will measure and explore the outcomes of innovations in curricula design, often by comparison with more traditional approaches. The work will build on a study conducted in the 1st year laboratory at UCD where students were presented with the problem of measuring the speed of light, as oppose to being instructed how to do the experiment. The work will be in collaborations with colleagues in the UCD Schools of Physics, Maths and Education.

Two fully-funded 4-year PhD positions starting from September 1, 2018. "Quantitative Modelling of Bio-Nano Interfaces"
Supervisor: Dr. Morgan Fraser
Applications are invited for PhD positions in observational astrophysics, working on supernovae and massive stars. Projects will entail using observational data from world-class observatories to understand the final stages in the life of a massive star. Stars above about 8 solar masses will end their lives with a spectacular explosion, as a core-collapse supernovae. These supernovae inject heavy elements and energy into galaxies, trigger star formation, and provide the building blocks of future stars and planets. However, many aspects of supernovae remain uncertain - including what type of stars explode, whether some collapse to form a black hole without a bright optical transient . Students will use data from a range of telescope facilities obtained through the PESSTO and NUTS collaborations to understand these fascinating events. Funding opportunities are available through IRC and other grants. For further details, please contact Dr. Morgan Fraser (firstname.lastname@example.org)
Supervisor: Dr. Deirdre Coffey
Applications are invited for PhD and postdoctoral positions in the area of Star Formation. Young stars are born via the gravitational collapse of a cloud of dust and gas into a stellar core where fusion begins. Any initial rotation of the cloud causes a circumstellar disk to form which becomes the building site for planets. Meanwhile, bizarrely, astronomers also observe high velocity bipolar jets being ejected from these young stars. The complex mechanisms involved in star and planet formation remain a mystery. Applications are invited to work on the interpretation of observations from world-class telescopes of young stellar objects, their disks and jets/outflows. PhD and postdoctoral opportunities are available continuously through self-funding IRC grants.

Optical microscopy is an important and widely used method for studying (soft) condensed matter. The resolution of optical microscopy is however limited by diffraction to imaging in the visible region of the electromagnetic spectrum to length scales >100 nm. As a consequence, present optical microscopy technology cannot image the many structures and (quantum) processes that occur on the nanoscale, which requires an image resolution of one hundred nanometres or less. Metamaterial-based optics enables imaging without a theoretically unlimited resolution in the far-field. Metamaterial optics restore evanescent waves and project sub-diffraction-limited images in wide-field. The application of this metamaterial-based technology to demonstrate optical imaging is a current research goal.
Supervisor: Dr. James Rice
Scanning near-field microscopy provides an optical resolution beyond the diffraction limit of conventional microscopy. Scanning near-field optical absorption imaging is based on the collection of scattered electromagnetic radiation via the near-field positioned aperture. Due to the elastic light scattering mechanism and the complex dielectric value of the sample recovery of precise absorption information is challenging. Combining atomic force microscopy and optical mythology is an alternative method to performing sub-wavelength absorption imaging. To date this approach has enabled a resolution of lambda/150. Developing and applying such mythology will enable detailed information of nanoscale optical processes and structure to be performed.
Transferable coarse-grained potentials for studies of proteins, nucleic acids and their interactions
Supervisor: Dr. Vio Buchete
The development of coarse-grained interaction potentials is an active area of research in computational molecular biology and structural bioinformatics. Accurate coarse-grained modeling methods will likely lead to simulations that can go beyond the studies of fast and local events, enabling the study of slow, non-local conformational rearrangements in biomolecules. Such approaches will enable large-scale, genomic-wide studies of biomolecular structure, dynamics and interactions. Coarse-grained modeling efforts of proteins and protein-protein interactions have included system-specific information(e.g., native state information in a Go-like manner). Physics-based, transferable models have recently been developed, yet they are relatively complex and their efficiency is still under testing. Alternatively, statistical analysis methods were used to derive parameters for new distance and orientation-dependent potentials from protein structural databases, a major advance over earlier approaches that included only inter-residue distances. This project will systematically advance the development of coarse-grained potentials by comparing and combining the complementary information offered by these two approaches.
Supervisor: Dr. Vio Buchete
Key to the success of a multiscale approach in molecular simulations is that information is exchanged accurately and efficiently between the layers of resolution. Preliminary results from large sets of molecular dynamics (MD) trajectories that sample exhaustively the conformational space of short peptides provided a quantitative measure of the limits imposed by the intrinsic information loss that occurs when switching from an atomistic to a coarse-grained representation. Even for a simple two-state mapping of the conformational space of a single residue in a peptide (e.g., helix-coil), various types of transition paths can occur. Therefore, even for short peptides, the dimensionality and complexity of the simplest nearest-neighbor kinetic model can be large, and the full, accurate structure of even a coarse-grained transition rate matrix can be very difficult to estimate. This project will advance the recently developed master equation-based methods for analysis of molecular simulations for finding the simplest yet accurate coarse-grained representation of a system, and the corresponding kinetic pathways. Methodologically, these studies are important because the knowledge of the accurate coarse-grained kinetic pathways can be used to drive atomic-level MD algorithms, leading to faster, larger scale simulations and to more accurate kinetic analysis methods.

Amyloid fibrils are of outstanding interest as they are associated with a wide variety of diseases, including Alzheimer's, Parkinson's, Huntington's, prion diseases, and diabetes, and also with new types of nano-materials. The detailed structural characterization of these self-assembled structures is a central step toward the understanding of the mechanism leading to the formation and stability of ordered, fibrillar aggregates. This project will study the effect of the environment (e.g., hydrophobic/ hydrophilic interfaces or molecular crowding agents) on the kinetic and thermodynamic properties of peptide folding and aggregation. Based on atomically detailed, explicit solvent, MD simulation of Alzheimer's amyloid fibrils, we will perform coarse-grained simulations of fibrils that would permit the study of more realistic, larger fibril segments. The new residue-level models would incorporate structural details revealed by all-atom simulations and by experiments (e.g., solid state NMR). Applications range from the study of fibril nucleation/growth inhibitors (i.e., potential drugs) to the control of amyloid formation and to the design and development of new types of nanomaterials.

Since 2001, there has been an explosive growth of scientific interest in the role of plasmons in optical phenomena, including guided-wave propagation and imaging at the subwavelength scale, nonlinear spectroscopy and negative index metamaterials. Building on our extensive experience in the field of plasmonics, in this project we are extending our research to the direction of ultrafast plasmonics. Tailor designed RUNs (Resonant Ultrafast Structures) will be developed using a combination of PVD (Physical Vapour Deposition) and FIB (Field Ion Beam) technologies, available in house. In this project, in combination with a state of the art ultrafast laser source (10 fs), measurement and imaging techniques such as, PEEM (Photo-Emission Electron Microscopy), FROG (Frequency Resolved Optical Gating), SPIDER (Spectral Phase Interferometry for Direct Electric-field Reconstruction), s-SNOM (scattering Scanning Near-Field Optical Microscopy), will be employed to investigate Surface Plasmon dynamics on the RUNs at femtosecond timescales and nanometer spatial resolutions. In addition to the experimental characterisation, computational analysis will be carried out using Greens functions and finite element methods.
Supervisor: Dr. Dominic Zerulla
Currently, plasmonics is a cutting edge, enthusiastic and quickly growing field of research that offers seemingly endless research opportunities [e.g. Science, 189, 311, 2006, Phys. Rev. Lett. 98, 133901, 2007]. It has already presented important influences in varied fields of research, from bio-analysis and sensors to magneto-optics and nano-manipulation. At the very heart of this field is fundamental research on Surface Plasmon Polaritons (SPPs) - mixed states of photons and electron density waves which propagate along the surface of a conductor. This project introduces a new degree of freedom into the field of plasmonics: the electron spin. We will initiate a novel opto-electronic technology platform for information processing and data storage based on Plasmonic and Spintronic (Spin Electronic) concepts. This new hybrid field is referred to as Spin-Plasmonics. Techniques including, MPMS (Magnetic Property Measurement System), high magnetic field cryogenic temperature spectroscopy, MFM (Magnetic Force Microscopy), PEEM (Photo-Emission Electron Microscopy), will be employed to investigate the Surface Plasmon dynamics on Multilayer magneto-active structures.

Two PhD positions are available in the advanced photovoltaic fields of dye sensitised solar cells and II-VI nanorod solar cells. Excitonic solar cells - including organic, hybrid organic-inorganic and dye-sensitized cells (DSCs) - are promising devices for inexpensive, large-scale solar energy conversion [e.g. Nature Materials 4, 455 - 459 (2005)]. DSCs are currently the most efficient and stable excitonic photocells. Central to this device is a thick nanoparticle film that provides a large surface area for the adsorption of light-harvesting molecules. Nanorod solar cells generate new degrees of freedoms in the design of photovoltaic devices. By controlling nanorod parameters, the distance over which electrons are transported directly through the thin film device can be modified. Tuning the band gap by altering the nanorod radius enables optimization of the overlap between the absorption spectrum of the cell and the solar emission spectrum. The PhD students will have the responsibility of designing new cell types, and to optimise their efficiency using (e.g.) laser spectroscopy and a variety of imaging techniques (SEM, PEEM, AFM) in order to control the cell development progress. The candidate must be self-motivated, willing and capable to work both independently and as part of a team. The candidate must have received (or anticipate receiving) a 1st or upper 2nd class honours degree in Physics, Material Science or a suitable Engineering discipline.

Since two decades scientists have been successfully using physical models for describing collective behaviour of living organisms. Such was the theory of flocking by Tamas Vicsek that explored the analogy between alignment of magnetic dipoles and flying birds. The success of social physics is based on the fact that many macroscopic properties of large groups are independent of the microscopic, individual details of the active agents. This allows us to develop generic models of collective behaviour that imitate an enormous range of phenomena from collective cell migration to human opinion dynamics or car traffic. The degree of collectivity is then analysed by methods of none-equilibrium and equilibrium statistical physics. This PhD project is theoretical and will involve developing theory and computer simulations of social systems to study interactions, polarisation, and opinion dynamics.

Modern biotechnology and medicine have been developing fast and exploiting novel advanced materials. Personalised medicine involving lab-on-a-chip devices, medical imaging and diagnostics using nanoparticles, sensors, implants and food processing units involve sophisticated surface modification and depend on our understanding of the bionano interface – the nanoscale layer where engineered materials and biomolecules come in contact. Moreover, understanding of the bionano interface is required for assessment of toxicity of industrial nanomaterials like carbon nanotubes. In our lab, we develop computational methods for modelling bionano interface and prediction of interactions between biomolecules and foreign materials. We lead a European consortium SmartNanoTox working on nanomaterial toxicity assessment and collaborate with biologists, medics and chemists across Europe. The PhD researcher working on this project will join a team developing multiscale modelling techniques based on statistical physics, bioinformatics and biophysics to predict the safety of biomaterials.
