Dear colleagues,


please find attached two job offers for positions for Ph.D students at University of Bremen, related to a research project on social networks and social inequality using big data, survey and interview data, led by Mario L. Small (Harvard).


We are grateful if you could forward this to possible candidates.


Thank you!

Betina Hollstein and Mario L. Small



The University of Bremen, U Bremen Excellence Chair Prof. Mario L. Small PhD/ Research Group "Large-Scale Data and Field Research in the Study of Social Networks" at the SOCIUM – Research Center on Inequality and Social Policy, invites applications for the following position

2 x 50% Research Associates (f/m/d) – Positions for PhD-candidates in Sociology

German pay-scale EG 13 TV-L (50%),

part time (50%) and limited until December 31, 2023
Start of contract: January 1, 2021.

The time limitation is based on § 2 (1) WissZeitVG (Wissenschaftszeitvertragsgesetz, i.e. temporary science employment act). Therefore, candidates may only be considered who dispose of the respective scope of qualification periods according to § 2 (1) WissZeitVG.

The University of Bremen, a mid-sized university with 320 professors, 19.500 students and a full-spectrum of academic disciplines is one of Europe’s leading research universities and maintains close cooperation with international universities and non-university research institutions in the region. The promotion of young researchers is a core element of Bremen's research strategy.

The 'U Bremen Excellence Chairs' program is a new initiative at University of Bremen since 2019. It enables internationally outstanding researchers to establish their own working groups at the university and to integrate them into a network of excellent research institutions worldwide in their respective disciplines. Mario L. Small's research group will study “Large-Scale Data and Field Research in the Study of Social Networks.”  One major promise of “big data” was the ability to understand how social networks emerge, operate, and shape human behavior on a much larger scale than previously possible.  However, as wide-eyed enthusiasm has given way to sober analysis, researchers and the public have become increasingly aware of the limitations of such data.  This project will examine the extent to which field-based research (interview and survey research) can help address the limits of computationally intensive analysis of large-scale administrative data. Focusing on problems such as boundary specification, locality of interaction, algorithmic confounding, and misinterpretation of meaning, we will examine the extent to which bringing field research to bear on the analysis of large-scale administrative data can help improve our understanding of the relationship between networks and social inequality.
