Dr. Omer Khalid

I received BSc (Hons) in Computer Science at University of Greenwich, UK with a first class distinction in 2005. During my Bachelors studies I spent a year working at European Organization for Nuclear Research (CERN), Switzerland. In 2006, I acquired Phd scholarship at CERN in collaboration with University of Greenwich, and later continued my research work at CERN as a senior research fellow.

Research Interests: Cloud, Grid and Cluster Computing, High Performance Computing, Green and GP-GPU Computing, Simulation and Modeling, Scheduling and Optimization, Machine Learning Algorithms, Software Design and Distributed Architectures.

European Organization for Nuclear Research (CERN)

Senior Research Fellow

Senior research fellow for investigating and deploying Siemens software development environment on cloud platforms, and executing security evaluations and improvements in network based data acquisition systems. Responsibilities included:

• Deploying and configuring cloud platforms (OpenNebula and Eucalyptus) on a high performance computing cluster, and developing software to integrate it into CERN environment. Developing software prototypes for PLC STEP7 software environment, and integrating them with CFEngine configuration management system. Conducting intrusive network robustness tests to launch man-in-middle attacks on SCADA systems to identify system vulnerabilities.

European Organization for Nuclear Research (CERN)

Doctoral Researcher

Working on optimization of the job throughput for CERN’s grid workloads using virtualization technology, and integrating it into production applications for on-demand virtual machine deployment. It involved scheduling algorithms using signal processing and statistical techniques.

• Thesis title: “Reducing Deadline Miss Rate for Grid Workloads running in Virtual Machines: a deadline-aware and adaptive approach”.

European Organization for Nuclear Research (CERN)

Software Engineer

Lead developer for the software to manage USB based front-end electronics hardware used by a high energy physics experiment. Responsibilities included:

• Developing Java/JNI software for a USB controller which acted as a front-end configuration system for CERN’s high energy experiment. Integrating low-level C/C++ libraries for a USB controller into custom developed Java application.

European Organization for Nuclear Research (CERN)

Software Engineer

Software developer to migrate software for single board VME based embedded systems and developing J2EE applications to streamline operations within the team. Responsibilities included:

• Porting OS9 software/driver modules to GNU/Linux for single board computers on VME/Camac industrial buses. Developing device drivers (C/C++) for oscilloscopes for GPIB industrial bus. Development of a PHP based web-application to allocate and manage hardware ID’s for all USB and PCI devices designed at CERN. Developing a J2EE enterprise application to manage hiring of electronics equipment from CERN’s electronic store.
