I very much enjoy supervising and mentoring students.
Since graduating in 2006, I have been supervising and/or
assisting in the supervision of students at the University
of Saskatchewan (Canada), University of Calgary (Canada),
IIT Delhi (India), NICTA (Australia), and
Linköping University (Sweden).
NEWS: I am looking for highly self motivated students with interest
in computer networks, security, distributed systems, performance/systems modeling,
or data mining/analysis.
Please contact me if you are interested in doing a project or thesis in one of these topics.
Current PhD students
Rahul is co-supervised with Nahid Shahmehri and Patrick Lambrix. His research proposes new
collaborative distributed security protocols and uses measurements to analyze BGP security.
His work characterizing the China Telecom incident on April 8, 2010, appeared in
PAM 2013 (pdf).
Vengatanathan is co-supervised with Nahid Shahmehri. His research on proxy-assisted
HTTP-based streaming (HAS) appeared in IEEE MASCOTS 2013 (pdf)
and his work on nonlinear
multipath streaming won the best paper award at the
ACM SIGCOMM workshop FhMN 2013 (pdf).
Anna is co-supervised with Nahid Shahmehri. Her research is on Web authentication and
federated identity management.
A large-scale measurement study of the identity management landscape appears
in PAM 2014 (pdf), and other exciting findings are under preparation.

Adele Lu Jia (PhD, 2013 @ Delft University of Technology, Delft, the Netherlands):
Tomas Kupka (PhD, 2013 @ Simula and University of Oslo, Norway):
We are in the process of building a new high-caliber
research group which specializes in the design, modeling, and
performance evaluation of distributed systems and networks.
We are therefore looking for highly self motivated students
that are interested in doing a project or thesis with in our group.
Please contact me if you are interested in doing a project or thesis with us.
Topics: Potential topics include, but are not limited to: content
distribution, sustainable and energy efficient ICT, peer-to-peer,
non-linear media, social networking, participatory sensing,
data/information-centric networking, as well as new architectures,
applications and services for smartphones.
Much of my ongoing research contributes towards providing simple and effective ways to disseminate
content and information to increasingly mobile clients.
As a more concrete example, we want to make the mobile Web faster and more energy efficient.
There are of course many other candidate topics, which I would be happy to discuss in person.
You can also find some recent research papers on my website.
Methodologies: We will always try to use the best tools for the
problem at hand. Our research include a combination of
measurements, data analysis/mining, applied statistics,
analytic modeling, optimization,
simulations, system implementation and design, as well
as real-world experiments. We are looking for ambitious
students interested in applying a subset of these methodologies to improve and better understand systems.
Prospective thesis and graduate students:
I am always looking for self motivated and ambitious students.
If you fit the above description, please send me an email.
There are always bachelor and master's thesis projects avalible.
We are also constantly looking for good PhD candidates.
To indicate interest, you can send me an email with your CV, transcripts
(scanned, including grades and degrees, if applicable), and a cover
letter (in which you describe why you are a suitable candidate).
Any attachments should be in pdf format.
(Other formats will not be opened.)
PhD Candidates ("doktorander", in Swedish) should have a
MSc degree in Computer Science, Engineering, or other related
discipline. While a strong background in mathematics is a plus,
this is not a requirement. (See description of methodologies above.)
The primary requirement for these positions is that you are ambitious,
hardworking, and interested in doing high-quality research.
PhD candidates are employed with a monthly salary.
There are thesis projects available for ambitious students.
Particularly strong, ambitious, and hardworking masters students can be
accepted/promoted into the PhD program.
There are some thesis projects available for ambitious students.
Example projects for BSc/MSc thesis
There are some candidate thesis topics that I would be particularly excited finding
good students for (many of which are related to our ongoing research projects).
Rather than listing all these projects publically, I am happy
to sit down individually with suitable candidates and discuss such projects.
(For some projects, including the ones listed below, there are also some brief summary write-ups
that can be shared with students genuinely interested in doing a project.)
Below are some very brief example announcements for project we are hoping to find people.
As hopefully suggested from the above descriptions, there is the potential for
a wide variety of other candidate projects as well.
I encourage you to check out
my publication page for
example papers and topics that I actively research.
Content and service delivery: There are many projects here that would
allow you to learn about different services at depth; perhaps even your favorite service
(e.g., BitTorrent, Netflix, Skype, Spotify, YouTube, etc.).
If you are curious, like to investigate, and/or just like to build your knowledge,
these projects may be of interest of you.
- Hockey interested and interested in data mining (or statistics)?
If this sounds like you please contact me. We have the perfect project for you!!
We also have other data mining and/or data analysis oriented projects.
- Interested in learning about the weaknesses of SSL and Web security? There is a very
interesting project for you! We also have a number of other security-related projects.
- Interested in analytic modeling or mathematics? This may be a great
opportunity to apply those skills to better understand how systems, networks,
and/or services work and should best be designed.
- We are looking for a student to help in the design and implementation of a
Planetlab demonstrator and teaching tools.
- In a multimedia-related work (that will involve working with the user interface),
we are looking for a student that is good at ActionScript 3.0
