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.

Majors:

  • Acoustics and Audio Technology AAT
  • Communications Engineering CE
  • Human-Computer Interaction HCI
  • Speech and Language Technology SLT

  • Signal Processing and Data Science SPDS

Note: Part of the professors of the major in Acoustics and Audio Technology & Human-Computer Interaction work in the department of Computer Science. You can find their information from School of Science Computer Science thesis supervisors list.
