Aalto University is a community of bold thinkers where science and art meet technology and business. We are committed to identifying and solving grand societal challenges and building an innovative future. Aalto University has been ranked the 9th best young university in the world (Top 50 under 50, QS 2018) and one of the world’s top technology challenger universities (THE 2017), for its outside-the-box thinking on research collaboration, funding and innovation. Aalto has six schools with nearly 11 000 students and 4000 employees of whom close to 400 are professors. Our main campus is located in Espoo, the capital area of Finland.

We believe that people from diverse backgrounds can together reach the best results. Diversity is part of who we are: for example, over 40% of our academic faculty comes from outside Finland. We warmly encourage qualified candidates from all backgrounds, especially minorities, to apply, as we want to ensure our community’s diversity and inclusiveness in the future as well. We are committed to equal and transparent recruitment procedures.

 At Aalto, high-quality research, art, education and entrepreneurship are promoted hand in hand. Disciplinary excellence is combined with multidisciplinary activities, engaging both students and the local innovation ecosystem. Our main campus is quickly transforming into an open collaboration hub that encourages encounters between students, researchers, industry, startups and other partners. Aalto University was founded in 2010 as three leading Finnish universities, Helsinki University of Technology, the Helsinki School of Economics and the University of Art and Design Helsinki, were merged to strengthen Finland’s innovative capability.

We are now looking for a Postdoctoral Researcher working on simulations of Dynamic Ground Exchange with the Material Point Method

Problem to be solved

Are you interested in your research having an impact on engineering practice? Are you interested in contributing to a reduction of material use and CO2 emissions in construction? We are now looking for a researcher who would work on an Academy of Finland project developing the Granular Material Point Method and simulate impact compaction and dynamic ground exchange.

The impact compaction methods of soil improvement are much more environmentally friendly than most used alternatives like piling or soil mixing. The research should provide the basis for a wider application of impact compaction and dynamic soil exchange for soil improvement in Finland and abroad. This will help to reduce the cost and the CO2 emissions related to construction, aiding the Finnish goal of being carbon neutral in 2035.

Your first task will be to replicate with Granular Material Point Method the observed soil behaviour during the impact compaction both at the laboratory scale and field scale. Later, you will use the validated simulation framework to investigate the use of impact compaction in a new environment, as well as check how to reduce the impact of vibrations on the neighbourhood. Based on your research you should be able to give updated guidelines for the design and application of dynamic compaction and dynamic soil exchange. Additionally, you will contribute to the development of the Material Point Method and numerical algorithms, as well as to other research related to soil improvement.

Your network and team

Your research will build on more than a decade of successful research on the Material Point Method in the group of Prof. Sołowski that led to the development of the Granular Material Point Method, a numerical method now suitable for the simulation of material mixing. In your research, you will cooperate with the researchers in the group of Professor Sołowski, who are working on the development of the Granular Material Point Method and the industrial and academic partners of the project.

The partners of the project include global companies, such as Menard, ELU Konsult, AFRY, Ramboll as well as the Finnish Transport Infrastructure Agency (Väylävirasto). The academic partners are Chalmers University, the University of Utah and the Silesian University of Technology. The project will include research visits abroad.

Your experience and ambitions

You should be motivated and willing to succeed in performing world-class research. You will be working and developing Uintah software, a very powerful code written in C++ developed in Utah, US, as well as at Aalto University. Hence, an ideal candidate for the offered post should have general knowledge of programming and a good knowledge of C++ or fluency in another programming language is necessary. Basic knowledge of Linux would help in starting the work smoothly. Furthermore, it is advantageous to know continuum mechanics well, as well as how constitutive models of materials are defined in the continuum mechanics framework. You also would benefit from being familiar with numerical methods and algorithms they use, as well as the basic knowledge of the differential equations describing material behaviour, including its behaviour under dynamic impact. The compacted material will be described with critical state soil mechanics, and hence the understanding of soil and granular materials behaviour is beneficial. Your previous research experience should support the research subject. This could stem from a large number of backgrounds, including research related to the constitutive modelling of soils, software development and development of the Material Point Method.

For the position, it is recommended, but not strictly required that you took courses on geotechnical engineering and that you know well and understand the limitations of constitutive models for soils, such as Mohr-Coulomb and Modified Cam Clay as those constitutive models will be the starting points for your research. Additionally, some knowledge related to fracture mechanics, water flow in porous media, compaction of granular materials and how material microstructure affects its macroscopic properties is welcome.

The post requires excellent English language skills. For the position, we are seeking applicants that have the ambition to conduct world-class research, publish in top journals in the field and become world-class researchers in the future.

What we offer

We offer work in a very stimulating environment where you will conduct world-class research and publish your research results in leading scientific journals. The project you will be working on will provide you with valuable contacts both at universities and in companies. You will also gain experience on research visits, for example to the Silesian University of Technology, Poland, Chalmers University, Sweden and the University of Utah, US.

Aalto University offers the possibility to work within a well-resourced learning community where students are rigorously selected and highly motivated. According to its strategy, Aalto University targets at shaping a sustainable future by renewing society with research-based knowledge, creativity and an entrepreneurial mindset. The values of the university are responsibility, courage and collaboration.

The initial salary will be defined according to Aalto University salary scale for postdoctoral researchers. In addition to the salary, Aalto University provides its employees with occupational healthcare services and retirement benefits. Finland also has a comprehensive social security system.

Finland offers a safe and healthy environment for living with excellent state-subsidized services including affordable daycare, health care, and free schools ranked among the best in the world. Finland is among the best countries in the world, according to many quality-of-life indicators, including – for the fifth year in a row – being the happiest country in the world (UN study 2022). We are one of the world’s most reliable and stable nations with a high level of safety. With high investments in R&D, a strong innovation culture, open data, and advanced state of digitalization, we are a nation of innovation and entrepreneurship.

The Nordic values of equality and cooperation are rooted deeply in our society. Gender equality, flexibility and low hierarchy form the core of our Nordic working environment.
