Student Assistant in New Media & Digital Culture

The research project TANKIES (PI: Gavin Mueller) is hiring a part-time student assistant to conduct empirical investigations into digital political subcultures on social media platforms (eg Twitter, YouTube, TikTok) to better understand the impact of new media on political beliefs and historical understanding.

This is what you will be doing

• You will be using digital methods (eg. TCAT, Zeeschuimer, YouTube Data Tools) to explore how followers of far-left anticapitalist views are creating content, forming organizations, and spreading political messages through new media content genres (memes, short-form video, podcasts, conspiracy theories).
• You will produce data visualizations, map issue networks, and provide general “lay of the land” of the digital political subculture of anti-imperialist Marxism-Leninism, sometimes called “tankies.”
• Along with the PI, you will develop theoretical approaches to how politics and digital culture blend in digital environments through brainstorming, discussion, and potentially through original writing.
• We will meet every one or two weeks.

This is what we ask of you

• You are organized and a good communicator in English.
• You understand how to use Digital Methods tools provided as part of the UvA Digital Methods Initiative to produce empirical research.
• You possess an up-to-date knowledge of new media content genres on social media (eg. memes, viral content,
• You are fluent in the functioning of popular social media platforms (eg. YouTube, TikTok, Twitter, Reddit, Facebook), as well as more niche/underground spaces (eg. 4chan, Discord, Rumble)
• You have exposure to theories and methods of research on new media and digital culture.
• You are creative, with the initiative to make your own connections and follow your own hunches about where investigations might lead.
• Knowledge of far-left anticapitalist political content online (eg. Chapo Trap House, Jacobin Magazine, anticapitalist influencers and journalists) a plus;
• Knowledge of Marxist theory, histories of socialism/communism a plus
• Knowledge of communist/anti-imperialist/Marxist-Leninist theory/history/organization a big plus!

This is what else we offer you
We will work closely on producing academic work: papers, presentations, and eventually a book project. Other possibilities include organizing symposia, guest lectures, and presenting at conferences.

We aim for a preferred starting date of March 15th, 2026. The contract will be for a period of 12 months.

This is where you'll be working
You will be working on a project by a researcher in the Department of Media Studies at the University of Amsterdam, the top-ranked media studies department in the world. While working under dr. Mueller, you will be part of a large, dynamic network of researchers and educators in the New Media team, including designers of digital methods tools, that produces cutting-edge research on issues central to digital society and culture. The environment is international, interdisciplinary, collegial, creative, and highly collaborative.

PhD Position Application of Planetary Radio Interferometry and Doppler Experiment

Job description

We are seeking a highly motivated PhD candidate to strengthen the scientific exploitation of PRIDE (Planetary Radio Interferometry and Doppler Experiment) observations by developing and applying open, reproducible analysis pipelines for deep-space mission tracking. You will be embedded in the PRIDE collaboration and contribute directly to enhancing the scientific return of past, current, and upcoming planetary missions, including the Jupiter Icy Moons Explorer (JUICE).

A core element of the position is the use and extension of the TU Delft Astrodynamics Toolbox (Tudat) open-source astrodynamics toolbox for state estimation and orbit/parameter determination, enabling rigorous fusion of PRIDE observables with conventional radiometric tracking data. Your work will bridge radio data analysis, planetary science, and software development, and will directly contribute to improving the accuracy, traceability, and accessibility of advanced orbit determination methods for the broader community.

Key responsibilities

• Process, calibrate, and characterize PRIDE open-loop Doppler and phase-referenced VLBI observables.
• Implement, validate, and document workflows to integrate PRIDE data into least-squares orbit determination and parameter estimation using Tudat, with an emphasis on transparency and reproducibility.
• Analyze combinations of PRIDE and classical radio science data to missions such as Mars Express, Venus Express, Juno, and JUICE, aiming to improve reconstructed spacecraft trajectories and enable higher-quality science products.
• Contribute to extending Tudat’s capabilities for PRIDE-relevant use cases (e.g., tracking observable handling, interfaces, estimation settings, and automated validation).
• Deliver high-quality, FAIR research outputs: curated datasets, clear documentation, peer-reviewed publications, and open-source software that can be reused by both the PRIDE collaboration and the wider astrodynamics and radio-science communities.

Job requirements

• A Master’s degree (or equivalent) in Aerospace Engineering, Mechanical Engineering, Physics, Astronomy or similar.
• Strong software engineering skills in Python.
• Strong background and research experience in astrodynamics/orbit determination and numerical methods.
• Experience in usage of PRIDE data is a strong plus. Experience in usage of radio science data is a plus.
• Experience in the usage and development of Tudat is a strong plus. Experience in usage and development of Tudat or a similar tool is required.
