On this page you can find general descriptions of research topics from professors and lecturers linked to the CCIS programme, ELEC departments. By reading the descriptions you can get an idea of the fields where each professor/lecturer may supervise a thesis. Funded thesis positions in the research groups of the department are announced separately. These descriptions will help you with finding a supervisor (and a topic) when

  • it's time to start the thesis work but you don't have a topic yet. Contact the professor(s) whose expertise matches with your interests. 
  • if you already have your own proposal for a topic, e.g. obtained from industry or elsewhere, and you need to find a suitable supervisor.

Also a professor from another department or school in Aalto may act as the supervisor, as long as the topic itself is connected to the advanced studies of your degree.

Pasi Lassila

My research typically involves stochastic modeling of ICT systems and data networks. Recently, I have been working on various resource allocation and scheduling problems in the context of future cellular systems as well as data centers. Methodologically I am interested in applying queuing theoretic analysis on the models, including stochastiuc optimization techniques, as well as also using discrete event simulation to study the systems. A good background for a master's thesis is provided by basic understanding of Markov processes, the M/G/1 queue and good programming skills, for example from the course ELEC-E7450 Performance Analysis and/or ELEC-E7460 Modeling and Simulation.
