Are you interested in geoinformatics, big data and social media analytics? Are you curious about the phenomena of human mobility, tourism, transnationalism, regional planning and development?         I’m currently looking for a master’s student to work as a research assistant in my project BORDERSPACE at the Digital Geography Lab.

In short, the project studies cross-border mobility flows within the EU and daily practices of cross-border commuters (mobilities and activities across state borders). For this, we are using social media data such as Twitter data (Aagesen et al. 2022; Järv et al. 2022); smartphone tracking data (Järv et al. 2021), and questionnaire survey data. The project seeks to reveal functional cross-border regions based on cross-border practices of people, and how these are influenced by external factors (e.g., COVID-19, war in Ukraine). Also, the topics of transnationalism and multi-local living are in the focus of the project. Geographically, the project focuses preliminarily on the Nordic countries (incl. Finland-Estonia) and the Greater Region of Luxembourg.

The hired assistant would help with various tasks depending on skills and interests: processing and querying (social media) data, managing and developing the database, data analysis and report writing. In general, a successful candidate has fluency in programming (Python or R) and knowledge in automating (spatial) data analysis. Prior experience in handling databases (SQL, PostgreSQL + PostGIS), working with social media data and/or GPS tracking data is an asset.

For those interested, please send me (olle.jarv@helsinki.fi) an email including: 1) your CV; and 2) a one-page cover letter to introduce yourself, your skills and motivation, and whether you would potentially be interested to link this with your Master’s thesis study. The working period can be from January until the end of August 2023, so please indicate when you can start working, during what time period and at which workload (approximate work hours/week). Apply by 22.12.2022 at the latest.

Feel free to ask any further details, and to forward this email to potentially interested candidates at the University of Helsinki.

The BORDERSPACE project is carried out at the Digital Geography Lab — an interdisciplinary research team focusing on spatial Big Data analytics for fair and sustainable societies at the Department of Geosciences and Geography, University of Helsinki.

Are you interested in studying human mobility and social interactions that take place in the cross-border context, and doing advanced spatial and content analysis using millions of social media posts? If so, consider applying for a postdoc position at the Digital Geography Lab (DGL) to work with Academy Research Fellow Olle Järv from November 2021 (or sooner/later as agreed)!

We are looking for an enthusiastic, innovative, and open-minded team player with strong technical knowledge and skills to join our interdisciplinary DGL research group and work in the Academy of Finland-funded project BORDERSPACE – Tracing Interactions and Mobilities Beyond State Borders: Towards New Transnational Spaces.

Time flies – the course “GEOG-326 Quantitative methods for sustainable land use planning I: Accessibility & mobility analyses“, given by the researchers of the Digital Geography Lab, ended already before Christmas 2020. Yet it’s worthwhile to reflect on it!

It is heart-warming to go through the positive feedback from students regarding the course structure and balance between theory and practice, and constructive suggestions for improving the course.

The course aimed at linking the accessibility and mobility of people to sustainability, well-being and social (in)equality perspectives, exploring the potential of big data analysis approach, and studying the ways of implementing these in planning. We also focused on the impact of global crises on human mobility on the example of COVID-19.

Overall, all 35 students did a great job and received high grades, but most importantly, it was rewarding to see students getting motivated and inspired, and developing their skills and ideas during the course.

The final output of the course was an independent group work that was presented in the form of an academic poster. Me, Elias and Tuuli found the final poster presentation session excellent! Thus, we are delighted to share the posters here 🙂

Check out and get inspired!

Briefly in English: We are sharing an announcement for a post-doc/PhD student position at Digital Geography Lab and Ruralia Institute. The position benefits from the knowledge of Finnish language and hence is published in Finnish only.

Ja sitten suomeksi:

Kiinnostaako monipaikkaisuus, aluekehitys ja ihmisten liikkuvuus? Haluaisitko tietää, miten erilaisten digitaalisten aineistojen avulla voi monipaikkaisuutta tarkastella tai miten COVID-19 pandemia on vaikuttanut kakkosasuntojen käyttöä Suomessa?

Ruralia-instituutti ja Digital Geography Lab yhteiistyössä hakee tutkijatohtoria/tohtorikoulutettavaa hankkeeseen ”Monipaikkaisen asumisen rytmit”.

Tehtävät käsittävät digitaalisten massa-aineistojen (mm. rakennusten sähkönkäytön, matkapuhelinverkon ja Twitter aineistoja) hallinnointia, prosessointia ja analysointia. Hakijalta edellytetään riittäviä geoinformatiikan taitoja analyysien tekoon, massa-aineistojen käsittelyyn vaativaa osaamista (Python, R, PostgreSQL) ja tilastollista osaamista. Suurteholaskennan kokemus katsotaan eduksi.

Tarkemmat hakuohjeet löytyvät täältä.

Hakuaika päättyy 22.3.2021, ole nopea!

Are you interested in geoinformatics, big data and social media analytics? Are you curious about the phenomena of human mobility, cross-border mobilities and social interactions of people and transnational people? If yes, check this open four-year doctoral student position at the Digital Geography Lab starting from March 2021 or as agreed with the selected applicant!

We are looking for an enthusiastic, innovative, and highly motivated doctoral student with strong technical knowledge and skills to join our interdisciplinary research group Digital Geography Lab and work in the Academy of Finland-funded project BORDERSPACE – Tracing Interactions and Mobilities Beyond State Borders: Towards New Transnational Spaces.

The doctoral project has three objectives. First, to develop methodologies for quantifying human mobility and activity spaces across country borders based on social media data (Twitter). Second, to develop quantitative methodologies for uncovering activity practices of social media users and their feeling of belonging based on the content of their social media posts. Third, to conduct critical research on dynamic cross-border mobility flows derived from big data, integration of transnational people through their cross-border mobilities and social interactions, and how these are influenced by external factors such as the COVID-19 pandemic.

The successful applicant is expected to have strong fluency in programming (Python or R), experience in advanced spatial analytics and/or social media content analysis, and has worked with big data sources such as mobile phone, smart card and social media data. Prior experience in publishing research in academic journals, participating in research community and having a network of international scholars is an asset.
