PhD Advancing consumer acceptance of additive manufacturing technologies for repair & refurbishment

Job description

The research group of Responsible Marketing and Consumer Behaviour at the Faculty of Industrial Design Engineering (IDE) is looking for a PhD to do research on the transition to a Circular Economy through increasing consumer adoption of repair/refurbishment practices with the aid of additive manufacturing (AM) technologies (e.g., 3D printing).

The research group Responsible Marketing and Consumer Research focusses on theories and models from marketing and consumer research that can contribute to successful new product development (NPD). The group has experience in teaching and conducting high quality research on consumer behaviour in NPD, consumers' perceptions of new product designs, and on improving the acceptance of new sustainable alternatives. By enhancing knowledge in these areas, we aim to help designers create more successful and sustainable product and services.

A Circular Economy requires changes in consumer behaviour, such as adopting repair practices and purchasing refurbished products. However, consumers face barriers to adopting such circular behaviours. For repair, challenges include time, effort, lack of knowledge, high costs, availability of spare parts and perceived low product value. Repair and refurbishments are also met with scepticism, as consumers often associate it with lower quality and wear. As a result, repair is rarely considered, and refurbishment occupies a small share of the consumer market.

This PhD project will explore how AM can increase consumer adoption of repair and refurbishment, as AM offers unique opportunities for customization, fast and cost-effective repairs and enhanced product value. However, consumer perceptions of AM in repair and refurbishment contexts remain unclear, as does their likelihood of adopting these solutions based on product design integration. Accordingly, this PhD project aims to answer the following research questions:

1) What motivators and barriers do consumers experience regarding AM-based repair and remanufacturing? and 2) Which design strategies will increase consumer adoption of AM-based repair and remanufacturing?

To answer these research questions, we expect to use a mixed-method approach, including both consumer research (qualitative and quantitative) and Research-through-Design (RtD).

This PhD project will be part of a larger, NWO-funded project on Additive Manufacturing in repair and remanufacturing (called ADD-ReAM), which includes, in total, 15 PhDs who focus on other aspects such as technical design aspects, logistics, sustainability assessment, consumer behaviour, and more.

Job requirements
We are looking for a candidate with a background in design, consumer behaviour, psychology, or sustainability, who has a strong interest in studying the intersections between design, consumer behaviour, and sustainability.

The candidate should meet the following criteria:

• a Master degree in Industrial Design, Marketing/Consumer Behaviour, Psychology or in any related field.
• strong conceptual and analytical skills with an attitude for research and critical thinking.
• excellent methodological skills, preferably in both qualitative (e.g., interviews) and quantitative research methods (e.g., survey and experiments).
• very good command of English, reading, writing, and speaking, understanding of Dutch is considerd a plus, but not critical.
• a proactive, flexible and collaborative personality, motivated to engage with different partners involved in the project such as UTwente, TU Eindhoven, Erasmus University Rotterdam, Stichting Repair Cafes, Signify, Techniek Nederland and others.

All applications must be submitted in the form of three PDF files:

1) A motivation letter of not more than 1 page

2) A curriculum vitae including all grades obtained for the MSc degree

3) A reference letter written by a previous supervisor or employer

The starting date is planned for January 2026.

Phd Position in Digital AI chips for Next-Gen Analog/RF Systems (TUDelft - NXP)

Job description
As communication and sensing systems push towards higher frequencies and bandwidths (e.g., 6G, automotive radar), analog and RF front-ends are hitting a fundamental wall. In advanced CMOS nodes, it's incredibly difficult and power-hungry to design analog circuits that are perfectly linear, matched, and noise-free. The classic approach of over-designing the analog hardware is no longer sustainable.

This project pioneers a new paradigm: we design smart, low-power digital AI co-processors that learn and correct the imperfections of their analog counterparts in real-time. As a PhD researcher, you will:

• Architect and design novel digital AI accelerators that directly target analog impairments in analog-to-digital converter (ADC) and power amplifier (PA).
• Co-design algorithms and hardware with experts from TU Delft and NXP. You'll apply hardware-aware AI techniques (quantization, pruning) to create ultra-efficient solutions that fit a tight power and area budget.
• Quantify real-world impact by benchmarking your silicon prototype against traditional DSP methods. You will measure system-level improvements on actual analog test chips in NXP's labs.

You will be supervised by Dr. Chang Gao and Prof. Leo de Vreede and have daily access to TU Delft’s state-of-the-art IC design infrastructure and support from Dr. Maarten Molendijk, Dr. Robert van Veldhoven at NXP Semiconductors in Eindhoven for design reviews and hands-on lab measurements.

Electronic Circuits and Architectures (ELCA)
Join a pioneering research team dedicated to advancing the design and development of high-performance electronic circuits and systems. You will be part of the Electronic Circuits and Architectures (ELCA) section within the Department of Microelectronics at TU Delft. ELCA leads cutting-edge research in integrated circuit design, enhancing power efficiency, frequency performance, and functionality across RF, mm-wave, and wireless communication systems. The group bridges fundamental science with practical applications, pushing the boundaries of analog and digital circuit architectures.

You will have access to state-of-the-art design and testing facilities, including advanced fabrication technologies and specialized measurement labs. As part of a dynamic and interdisciplinary team, you will collaborate with experts in circuit design, signal processing, and emerging semiconductor technologies. The research environment fosters innovation through open collaboration and knowledge exchange. With strong mentorship, tailored training, and minimal hierarchical barriers, ELCA provides an ideal setting for academic and professional growth in the rapidly evolving field of electronic circuits and systems.

Job requirements
Essential Requirements:

• MSc degree in Electrical / Electronic / Computer Engineering, or a closely related field.
• Solid background in digital IC design and digital signal processing.
• Hands-on RTL design skills (SystemVerilog / Verilog / VHDL) plus scripting (Python / MATLAB / C/C++).
• Strong command of English.

Nice to have:

• Practical experience with machine-learning frameworks (e.g., PyTorch).
• Prior tape-out experience (ASIC or a complex FPGA prototype) and familiarity with the digital back-end flow (synthesis, P&R, timing closure).
• Knowledge of low-power digital design techniques (e.g., clock/power gating, DVFS).
• A strong curiosity about the challenges of analog/mixed-signal circuits (ADCs and PAs) and a passion for bridging the digital/analog divide.

Faculty Electrical Engineering, Mathematics and Computer Science
The Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) brings together three scientific disciplines. Combined, they reinforce each other and are the driving force behind the technology we all use in our daily lives. Technology such as the electricity grid, which our faculty is helping to make completely sustainable and future-proof. At the same time, we are developing the chips and sensors of the future, whilst also setting the foundations for the software technologies to run on this new generation of equipment – which of course includes AI. Meanwhile we are pushing the limits of applied mathematics, for example mapping out disease processes using single cell data, and using mathematics to simulate gigantic ash plumes after a volcanic eruption. In other words: there is plenty of room at the faculty for ground-breaking research. We educate innovative engineers and have excellent labs and facilities that underline our strong international position. In total, more than 1000 employees and 4,000 students work and study in this innovative environment.
