    Biography

    Rafael maintains the Linux kernel’s core ACPI and power management code, including the core infrastructure for IO device PM, CPU PM and system suspend/hibernation. He works at Intel Open Source Technology Center as a Software Engineer with focus on the mainline Linux kernel. He has been actively contributing to Linux since 2005, in particular to the kernel’s suspend/hibernate subsystem, power management in general (IO runtime PM framework, cpufreq, cpuidle, PM QoS, wakeup framework etc.), hot-plug infrastructure, ACPI core and PCI core. Since 2008 he has participated in multiple Linux Foundation conferences and other Linux-related events, including the Linux Foundation Collaboration Summit, LinuxCon (North America/Japan/Europe), Linux Plumbers Conference, Linux.conf.au, LinuxTag, and Ottawa Linux Symposium. He holds a PhD in physics from the University of Warsaw, Poland (2002).
