Speakers and Presenters

Workshop Presenters and Session Chairs

  • Dr Elsa Gonsiorowski


    System Software Developer, Lawrence Livermore National Laboratory

    Elsa received her PhD in computer science form Rensselaer Polytechnic Institute in 2016.

  • Dr Toni Collis


    Appentra Solutions and Women in High Performance Computing

    Dr Toni Collis is the CBDO for Appentra Solutions, Director of Collis-Holmes Innovations and Chair of Women in High Performance Computing (WHPC). Toni is a strategic manager in the HPC community as well as an experienced lecturer and trainer. The focus of her work has been on enabling those without detailed training in computer science and HPC to still use supercomputers. Her current role at Appentra focuses on democratising access to HPC by using the new Parallware technologies to lower the barrier for academics to write and maintain parallel software. Toni is passionate about enabling a broader range of people to make effective and efficient use of HPC facilities to help further their research. As Chair and Co-Founder of WHPC Toni also developed and led training aiming to diversity the HPC workforce by providing HPC tutorials for women academics and students in Europe.

  • Olivia O’Sullivan


    Science and Technology Facilities Council (STFC) Hartree Centre

    Olivia O’Sullivan is part of the Impact and Engagement team at the Science and Technology Facilities Council (STFC) Hartree Centre. Olivia’s work demonstrates the value of the Hartree Centre’s work in HPC, data analytics and cognitive technologies to industry and academic audiences. Using both digital and traditional mediums, she highlights the ‘people behind the projects’ and focuses on the social and economic impact of the Hartree Centre’s collaborative work. Olivia has a Masters in Science Communication and her written work has been published in scientific magazines and blogs. Before joining the Hartree Centre, Olivia worked in public engagement with biomedical research, designing bespoke public involvement initiatives around dementia and musculoskeletal disease.

  • Mozhgan Kabiri Chimeh


    University of Sheffield

    Dr Mozhgan Kabiri Chimeh​ is a Research Associate/Research Software Engineer in Massive Scale Complex Systems Simulation with Accelerated Computing at University of Sheffield (Department of Computer Science), UK. She works in the area of complex system modelling using emerging high-performance parallel architectures and her speciality is in performance acceleration targeting Many-core and Multi-core architectures. Currently, she is developing the FLAMEGPU software framework which allows complex systems modelling on GPU architectures.

    Previously, she worked on accelerating logic gate circuit simulation targeting heterogeneous architectures that involved optimising simulation algorithms and applying them to various parallel architectures (SIMD enabled machines, clusters, and GPUs).

  • Gokcen Kestor


    Oak Ridge National Laboratory

    Dr. Gokcen Kestor is a research scientist at the Oak Ridge National Laboratory (ORNL) in the The Computer Science Research group. Gokcen earned her Ph.D. in Computer Science from the Polytechnic University of Catalonia (UPC) in 2013, Barcelona. Her dissertation investigated effective software transactional memory solutions.

    Her research interests include resilience for future large scale systems, parallel programming models and runtimes, especially task based programming models, compilers, power and performance analysis and modeling of HPC applications and emerging technologies, investigations into effective use of emerging memory technologies and machine learning techniques in the context of HPC.

    She is currently working on fault tolerance solutions for distributed task-programming models, configurable soft error detection techniques, and evaluation of emerging memory technologies.
    She is a member of the ACM and IEEE Computer Society.
