Timothy Roscoe (Mothy)
CAB F 79
Note: My name is Timothy, or Mothy, but not Tim. Why would it be Tim?
I'm a systems research person: I build stuff.
I'm part of the ETH Zürich Computer Science Department's Systems Group. My main research areas are operating systems, distributed systems, and networking, with some critical theory on the side.
I have two main research interests right now:
- Operating systems for future machines that scale to thousands of cores, adapt to radically heterogeneous architectures, and handle the sheer complexity and diversity of modern hardware platforms.
- Monitoring, modelling, simulating, and managing entire datacenters in real-time based on detailed traces from the entire vertical network and software stack, and the systems software required to do this.
I also like collaboration. As well as my fellow conspirators in the Systems Group, I've been lucky enough to work with lots of wonderfully smart people, including recently Tom Anderson, Paul Barham, Andrew Baumann, Richard Black, Jon Crowcroft, Peter Druschel, Kevin Elphinstone, Tim Harris, Gernot Heiser, Joe M. Hellerstein, Rebecca Isaacs, Ihor Kuz, Petros Maniatis, Jeff Mogul, Sue Moon, Larry Peterson, Sylvia Ratnasamy, Sean Rhea, Oriana Riva, Scott Shenker, Livio Soares, Patrick Stuedi, Ion Stoica, and David Wetherall.
We're always looking for talented research students who like hacking on large systems. We have a number of projects available in networking, distributed systems, and OS design and implementation. See the Systems Group web pages for a few ideas, but also email me - we often have more up-to-date proposals available.
If you're thinking of applying for a position in the group:
- If you're interested in a postdoctoral position, following these instructions.
- If you're interested in pursuing a PhD in the group, follow the same instructions. Note that ETH Zurich generally requires you to already have a Masters degree. We do, however, have a so-called Direct Doctorate program for a limited number of high-quality Bachelor students, details are here. You may also find Steven Hand's excellent talk on Doing a Systems PhD useful (for here or elsewhere).
- If you're interested in a Masters degree, admissions are handled centrally in the department. See here for more information, including how to apply. If you specifically want to work with me for your Masters thesis, I suggest selecting the "Distributed Systems" track.
- If you want to simply do an internship, bear in mind that I only take interns under exceptional circumstances. Also, the number of applications I receive for internships is such that I cannot respond to most of them. Your best bet is to apply for our Summer research fellowship program.
I generally teaching the following courses at ETHZ; details can be found on the Systems Group course page:
- Systems Programming and Computer Architecture
- Advanced Computer Systems
- Advanced Operating Systems
- Big Data, Law, and Policy
- Datacenter Networking
Timothy Roscoe has been a Full Professor in the Systems Group of the Computer Science Department at ETH Zurich since 2007. He works on operating systems, networks, and distributed systems, including the Barrelfish research OS and the Strymon high-performance stream processor for datacenter monitoring. He received a PhD in 1995 from the Computer Laboratory of the University of Cambridge, where he was a principal designer and builder of the Nemesis OS.
After three years working on web-based collaboration systems at a startup in North Carolina, Mothy joined Sprint's Advanced Technology Lab in Burlingame, California in 1998, working on cloud computing and network monitoring, and spent time as an Industrial Fellow at the University of California at Berkeley Computer Science department, working with the Oceanstore project.
He joined Intel Research at Berkeley in April 2002 as a principal architect of PlanetLab, an open, shared platform for developing and deploying planetary-scale services, and worked on Declarative Networking, while becoming an Adjunct Professor at Berkeley.
In September 2006 he spent four months as a visiting researcher in the Embedded and Real-Time Operating Systems group at National ICT Australia in Sydney, which was developing the seL4 microkernel
Since joining ETH Zurich he has also spent time at Microsoft Research, Intel Research, and the University of Washington.
His current research interests include monitoring, modelling, and managing complex enterprise datacenters, system software for modern hardware, and system hardware for modern software. He was named Fellow of the ACM in 2013 for contributions to operating systems and networking research.
