Personal statement
Alastair Wark started his career with a BSc in Applied Chemistry in 1996 at the University of Strathclyde. He completed his PhD research in 2000 under the joint supervision of Dr Len Berlouis and Dr Frank Cruikshank at Strathclyde and also working with Prof. Pierre-Francois Brevet at the EPFL, Lausanne, Switzerland. Following post-doctoral research at EPFL he was awarded a Lindemann Trust Fellowship in 2001and joined the laboratories of Prof. Rob Corn at the University of Wisconsin-Madison. After moving across to the University of California-Irvine with Rob’s group and a Project Scientist position, Alastair returned to the Chemistry Department in late 2007 as a Lecturer in Nanometrology.
Research interests
My research focus is based around the synthesis, functionalization and analytical applications of novel nanomaterials alongside the development of techniques capable of optically imaging and tracking single nanoparticles and molecules. The advantages of these materials for nanometrology and bioanalytical science is that optical measurements can be performed to monitor biomolecular interactions in real-time. As well as developing robust methodologies for ultrasensitive bioaffinity detection at target concentrations approaching just a few molecules, we are also exploring the use of multimodal imaging techniques for monitoring nanoparticle-cellular interactions. This involves developing hybrid nanostructures which can be used for tackling research challenges requiring dynamic measurements in complex biological environments. Consequently, my research is highly multidisciplinary and I have enjoyed successfully collaborating with researchers from across the biology, physics, engineering and medicine research fields.

- This proposal seeks funding to deliver enhanced capability for characterising and assessing advanced nanomaterials using three complementary, leading edge techniques: Field-emission microprobe (EPMA), combined Raman/multiphoton confocal microscope (Raman/MP) and small angle X-ray scattering (SAXS). This suite of equipment will be used to generate a step-change in nanoanalysis capability for a multi-disciplinary team of researchers who together form a key part of Strathclyde's new Technology and Innovation Centre (TIC). The equipment will support an extensive research portfolio with an emphasis on functional materials and healthcare applications. The requested equipment suite will enable Strathclyde and other UK academics to partner with other world-leading groups having complementary analytical facilities, thereby creating an international collaborative network of non-duplicated facilities for trans-national access. Moreover the equipment will generate new research opportunities in advanced materials science in partnership with the National Physical Laboratory, UK industry and academia.

- "We propose to undertake an essential and cost effective upgrade of an existing high-power femtosecond laser system at Strathclyde to increase its output power, improve its stability and provide it with the necessary beam control and diagnostics systems to evaluate its performance and control (adjust) several important output beam parameters. The upgrade comprises a cryogenic cooler, to improve the power dissipation and thermal stability of the final laser amplifier Ti:sapphire crystal, a high-energy pump laser for the final amplifier, a wavefront sensor and deformable mirror system, to measure and control the wavefront phase, and an integrated 3rd-order cross-correlator, to measure the laser pulse contrast. The diagnostic systems are necessary to optimise the laser parameters and achieve the desired properties at focus. The cryo-cooler allows cooling of the final amplifier crystal to be increased from 28 W to 80 W, which enables the output power of the laser to be increased to 40 TW using the new high-energy pump laser. The upgraded will improve stability, increase intensity and shorten set-up and alignment times, thus increasing the usable time of the laser system to allow better use of the system and the beamline facilities at Strathclyde.
The upgraded laser will be used to deliver the objectives of a Critical Mass proposal (submitted simultaneously) that is part of the ALPHA-X project, which involves 5 universities (Strathclyde, Glasgow, St Andrews, Dundee & Lancaster), and external Collaborators. The research programme includes a study of collective radiation-beam-plasma interactions at high field intensities, the production of ultra-short duration high brightness particle beams from the laser-plasma wakefield accelerator (LWFA), development of new methods of producing coherent and incoherent radiation, and applications of the sources. The applications programme involves an investigation of using high energy electrons for radiotherapy and also methods to produce medical radio-isotopes for medical imaging. The facility will also be used as a platform for engaging with industry through proof-of-concept projects. The upgraded facilities will be transferred to the SUPA Scottish Centre for the Application of Plasma-based Accelerators (SCAPA) when the facility has been constructed."

- micromanipulation non-invasively in nanomaterial manufacture processes, to enhance direct control of nucleation, growth and structure development. Nucleation and assembly are the first stage of engineering nanostructured materials in applications including drug crystallisation, nanoparticle and nanoporous catalyst manufacture, and metal-organic frameworks for molecular storage. There is significant evidence that these complex microscale nucleation and assembly processes are strongly affected by local conditions such as flow. Our understanding of how flow and local (at the micron-scale) forces affect and thus could be used to control nanostructure nucleation is limited, because nucleation is inherently a local process while flow and external forces are usually applied globally. Therefore our novel, versatile OMNIFlow experimental platform will non-invasively impose local micron-scale flows by manipulating optically and magnetically trapped particles, generating local flow fields in the nucleating or assembling suspension. The project brings together Strathclyde expertise in microfluidics, optical and magnetic manipulation and quantitative dynamic microscopy, and focusses on applications in the key Strathclyde research strength of advanced nanomaterial engineering and science for innovative industrial applications. It will provide a unique experimental platform to highlight Strathclyde’s developing central role in this area.
