Current situation

 

Krste currently holds a position as a Research Associate at the Centre for Industrial Photonics, Institute for Manufacturing. His research interests revolve around high-speed dynamics in physical systems, particularly in high-energy laser physics. He is currently the supervisor for two doctoral students, Nadeem El Gabbani who is working on thrust balances for nano-newton force measurements and Lily Delimata, who is working on new additive manufacturing technologies for medical applications. Krste is also a supervisor for MRes projects for the EPSRC Centre for Doctoral Training (CDT) in Ultra Precision Engineering. Krste is a member of the management committee for EPSRC CIM in Laser Based Production Processes. Krste is a member of the AILU Early Career Researchers Committee. Krste is also a contributor to the Cambridge Advanced Leadership Programme, at the Judge Business School.

 

Background

 

Krste obtained his B.Sc in Physics from King's College London in 2004 and MSc in 2005 in Physics. Following his degrees he moved into business technology R&D, operating within the areas of Strategy and Product Development. During that time, Krste worked with some of the worlds leading firms across a range of sectors including NOKIA, Barclays Wealth Management, Dresdner Kleinwort, Royal Bank of Scotland, Deutschebank, Barclays and Linklaters. In 2009 Krste returned to pursue his academic interests by undertaking an MRes with the EPSRC CDT in Integrated Photonic and Electronic Systems (IPES), concentrating on ultrafast manufacturing laser amplification architectures and in 2010 proceeded to undertake his PhD studies under the supervision of Prof. Bill O’Neill. His doctoral thesis, "Temporal pulse design and analysis of silicon ablation using advanced pulse shaping and digital holography in the nanosecond domain” was carried out in conjunction with a TSB SMART Laser project, developing the next generation of low-cost, temporally addressable fibre lasers, in conjunction with the Optoelectronics Research Centre at the University of Southampton and SPI Lasers, Southampton. During this time, Krste invented and developed a variety of diagnostic tools for examining ultrafast laser phenomena including the FalconGHz - a GHz rate full-field pulsed digital holographic system. On completing his PhD, Krste returned to industry and joined the Home Office Digital Transformation team where in conjunction with the Government Digital Service he worked to develop the Registered Traveller programme, and led the strategy aimed at improving the Border Force academic & student UK entry procedures. On completing his work at The Home Office, Krste returned to the IfM, this time working as part of a National EPSRC Centre for Innovative Manufacturing in Laser Based Production processes, Energy Resilient Manufacturing Lasers Programme (Part 2) as well as a variety of projects relating to additive manufacturing, ultrafast phenomena and high precision diagnostics techniques. More recently, he has extended his research activities to laser-based thrust and vectoring for space exploration applications.
