Doctoral Researcher in Physical Chemistry

The universities of Helsinki and Tampere, together with the Technology Industries of Finland Centennial Foundation and participating companies, run a joint DSII Scale-up Pilot project, which offers positions for doctoral researchers working in close cooperation with industry.

Of the eight researchers who will be selected for the program, half will be located at the University of Helsinki and half at Tampere University, but both universities participate in the guidance of selected doctoral students. This enables a unique opportunity for diverse and complementary research from theory to applications in a highly motivated, cross-disciplinary environment, while focusing on research questions that are directly relevant to industry and business.

The partner company for this position is Karsa. It develops and manufactures instruments for ultrasensitive chemical threat detection and environmental monitoring utilizing mass spectrometric detection techniques.

The employer for this position is the University of Helsinki.

Job description

The purpose of the job is to create new knowledge for academia and industry in the field of physical chemistry. The goals are:

  1. To develop new analytical offline techniques utilizing the Karsa MION technology and Orbitrap mass spectrometry

  2. To develop new online chemical ionization schemes for trace vapor detection

  3. Use the developed technologies in environmental monitoring for better understanding on sources of pollution and atmospheric chemistry.

As a doctoral researcher you will conduct research and contribute to the development of new methods and instrumentation for trace vapor and environmental pollution measurements. You will do instrument development, laboratory and field experiments and analyze the data of these experiments.

The results will be disseminated in scientific peer-reviewed journals, international conferences, doctoral network events and events with industry.

At the universities, the work will be supervised by University researcher Juha Kangasluoma (University of Helsinki), Prof. Tuukka Petäjä (University of Helsinki) and Assoc. Prof. Matti Rissanen (Tampere University). You will also be supported by practitioners in the steering group, including company representatives.

By participating in DSII events, excursions and meetings with your fellow doctoral students and the DSII team, you will both get and provide peer support and make your own contribution to the development of DSII.

DSII Scale-up Project requires the doctoral researcher to be ready to work on the campuses of both universities and also on the premises of the partner company when necessary.


You need to have an applicable master’s degree in atmospheric science, physics, chemistry, engineering, or a related discipline. The candidate should have excellent knowledge in one or several of the following fields:

  1. physics/chemistry (aerosol physics, physical chemistry, analytical chemistry, mass spectrometry),

  2. programming and data analysis (Python, Matlab),

  3. technical skills in working with scientific instrumentation, chemicals and gases.

Therefore, you need to have an inquiring mind and the ability to think independently while also being able to work in a team and be an active member of the DSII community.

A good command of English, both in writing and in oral presentations, is required.

How to apply & more info

The position will be filled for a fixed-term period of four years, starting in fall 2023, or as soon as possible thereafter.
