I am currently involved in
investigating and realizing the possibilities for efficiently implementing
lock-free data structures in object-oriented languages. Working implementations
in C++ for multi-threading have been established of most of the common abstract
data types. Further work is research on integration issues and expanding to
managed environments for developing parallel programs on contemporary systems.
Currently I have very
limited research founding (so I spend most of my time teaching), so research
initiatives for international or national collaborations are very welcome! I
would also welcome students for supervision to Ph.D. or M.Sc. if funding can be
guaranteed externally.
My honored supervisor during my Ph.D. education was Philippas Tsigas. My graduate
studies position was supported by ARTES. I did a major part of my research
within the ARTES project
"Applications of wait/lock-free protocols to real-time systems", (WARP) whose aim was to develop
and study new synchronization protocols and concurrent data structures, and
evaluate them in the context of real-time systems at the operating system kernel
level. I was also studying commercial Real-Time operating systems kernels, one
in particular called OSE.
I am also working part-time
for the company Parallel Scalable
Solutions AB.
During the years 1999-2005 I was a
member of the research group
Distributed Computing and
Systems at the Department of
Computing Science of Chalmers
University of Technology.
