Doctoral Student position in the field of Information Technology and Electrical Engineering / Electronics (Development of High Precision, Wide Range, Multi-channel CMOS Time-to-digital Converter (TDC))

University of Oulu works as part of the international science community to deliver new scientific knowledge and science-based solutions. We educate future pioneers to build a more sustainable, intelligent and humane world. 

Applications are invited for a full-time

Doctoral Student position

for a four-year period and is scheduled to be filled as of March 1, 2022 or as soon as possible thereafter. A trial period of six months is applied in the position. Research is supervised by Adjunct Professor Jussi-Pekka Jansson in the Circuits and Systems (CAS) research unit, Faculty of Information Technology and Electrical Engineering. The doctoral student position is related to project funded by the Academy of Finland.

Research area

A time-to-digital converter (TDC) measures the time interval between two or more timing signals and presents the result in a digital form. The operation is much similar to the analogue-to-digital converters but the measured quantity is time interval instead of analogue voltage. High precision TDCs are utilized in many applications such as measurement devices, high energy experiments in physics, high speed circuit characterization, telecommunication, medical imaging, optical spectroscopy and laser based imaging and ranging. The CAS research unit has a successful history in developing the state-of-the art TDC units for various applications.

Job description

The main task of this doctoral student position is the development of a new multi-channel, high precision CMOS TDC architecture. The target applications are in pulsed laser based sensing, imaging and optical spectroscopy. The target precision is

Doctoral Student Position in Wastewater Network Condition Monitoring

University of Oulu is an international science university creating new knowledge, wellbeing and innovation for the future through multidisciplinary research and education. Close cooperation with research institutes, companies and the public sector has created an internationally significant research and innovation hub that has changed the world. Every day 2.6 billion people use technology developed in Oulu. In addition, the university’s location close to the Arctic offers unique conditions for a wide variety of research.

The Water, Energy and Environmental Engineering Research Unit is opening

a Doctoral Student Position

to work on wastewater network management. The position will be based in the Water Supply and Wastewater Engineering Research Group led by Assistant Professor Pekka Rossi (www.oulu.fi/water/). The candidate will work in the WATCON research project dealing with data-driven assessment and management of water and wastewater network assets. Making informed decisions on condition inspections and renovations is relevant, as wastewater networks are critical ageing infrastructure and thus require large investments.  The goal of the project is to improve wastewater network condition assessment with inflow and infiltration quantification using hydraulic parameters and water quality analysis including multi-isotope approach. The project is carried out in collaboration with Aalto university, whose research in the project concentrates on wastewater network asset management including data derived from CCTV inspections.

The Water, Energy and Environmental Engineering Research Unit (WE3) research covers a broad area of expertise including hydrology, water resources, energy systems and environmental studies (www.oulu.fi/water). The research unit is a multinational group working in a modern, up-to-date research environment. The unit has a staff of 60 including 25 full-time doctoral students working with new discoveries in water resources science, engineering and management.  

Work description

A successful candidate is expected to have a background and experience in water engineering. Experience in wastewater network assessment and management will be considered as advantage. The candidate is expected to:

  • Conduct field research on wastewater networks and laboratory research
  • Study the hydraulics and selected water quality parameters for sewer inflow and infiltration monitoring
  • Compare the usefulness of different sewer condition assessment methods


Assessment of the applicants’ qualifications will be based on the following criteria:

  • Master´s degree in Civil Engineering or Environmental Engineering/Sciences with major in Water and Wastewater Engineering or an equivalent degree
  • Strong knowledge in Water Engineering including Hydraulics, Water and Wastewater management and Hydrology
  • Experience and interest in design and operation of wastewater networks
