Madelaine researches the ethics of retail robotics, focusing on how care ethics should be used to guide the design and deployment of robots in grocery stores or distribution centers. Madelaine’s work combines philosophical reflection, empirical research on the emotions of workers and customers, and collaborative design methods

Mariya Hendriksen

MSc (PhD candidate)

Mariya studies an exciting area of e-commerce: the use of multiple modalities. Some of the most common modalities are visual modality (e.g., product images) and textual modality (e.g., product titles and descriptions).

Prof. dr. Martijn Wisse

scientific director

Martijn received the MSc and PhD degrees in mechanical engineering from the Delft University of Technology, Delft, The Netherlands, in 2000 and 2004, respectively. He is currently a Professor with the Delft University of Technology.

Max Spahn

MSc (PhD candidate)

Mobile manipulation in dynamic environments requires new methods for motion planning as the environment is steadily changing over time, so that real-time reactivity is necessary. Moreover, the high number of joints available to the robot results in a highly redundant robot for most tasks.

Maximillian Kronmuller

MSc (PhD candidate)

My PhD project focuses on developing new methods for dynamic and stochastic vehicle routing problems, having the application of multi-vehicle on-demand last-mile delivery for retail in mind. We want to develop novel routing methods such that the desired trade-off between the fleet composition, operation cost, and system performance is achieved.

Mert Imre

MSc (PhD candidate)

My research project is on learning manipulation of objects for retail environments as grocery store and warehouses, and supervised by Jens Kober. From a robotics manipulation perspective, there are many interesting problems and challenges included in retail environments. 

Mozhdeh Ariannezhad

MSc (PhD candidate)

Mozhdeh studies cross-channel user Behavior. Albert Heijn offers multiple shopping channels to their customers: online shopping on the website, and offline shopping in stores. Our focus in this project is on modeling cross-channel user behavior.

Olivier Sprangers

MSc (PhD candidate)

Olivier studies probabilistic forecasting. In doing so, he designs methods that can provide a forecast range, instead of only a point. We are looking into neural network-based methods and Gradient Boosting Machine-based methods to provide us with probabilistic forecasts.

Prof. dr. Paul Groth

scientific director

Paul Groth is Professor of Algorithmic Data Science at the University of Amsterdam where he leads the Intelligent Data Engineering Lab (INDElab). He holds a Ph.D. in Computer Science from the University of Southampton (2007) and has done research at the University of Southern California, the Vrije Universiteit Amsterdam and Elsevier Labs.

Sami Jullien

MSc (PhD candidate)

Sami studies smart orders, using methods like reinforcement learning. In his project, we aim to create optimal orders that meet local differentiated availability in our stores, while being cost-efficient and environmentally friendly in the end-to-end supply chain. This is a complex interplay of factors, as we need to reduce waste and keep customer satisfaction high, while keeping costs at a normal level.

dr. Sebastian Schelter

(lab manager)

Sebastian is Assistant Professor with the University of Amsterdam, conducting research at the intersection of data management and machine learning.  He manages the AI for Retail Lab Amsterdam, and has a joint appointment as Research Fellow at Ahold Delhaize, an international retailer based in the Netherlands.

Shubha Guha

MSc (research engineer)

Shubha joined our lab in 2020 as research engineer. In doing so, she is vital in transforming research into results that can be presented and used. She has a Cognitive Science and Linguistics double major and previously worked as research assistant a UC Berkeley and at Text Kernel. 

Ir. Stefan Bonhof

MSc (team lead & technical support)

Stefan is the Team Lead for the MSc students who are doing their thesis at AIRLab Delft. This means that he is available to these students for feedback on their work, brainstorm sessions, advice and general banter. Next to that,  he acts as technical support for the AIRLab Delft Research team.

Stefan Grafberger

MSc (PhD candidate)

Stefan joined our lab in February 2021, after graduating in Munich. His PhD revolves around data management. Data is at the center of modern enterprises and institutions. Online retailers, for example, rely on data to support customers making buying decisions, to forecast demand, to schedule deliveries, and more generally, to guide every single business process and decision.

He co-directs the cross-departmental Expressive Intelligence Lab. From his background in cognitive artificial intelligence and human-robot interaction, he investigates and creates the intelligence necessary for robots to engage with the social back-and-forth. His current work applies devising methods from the performing arts to the creation of interaction dynamics for robots in retail and last-mile delivery.

Bassem Zaarour

Bassem studied Electrical and Computer Engineering, paired with a Master’s in Management of Technology and after having worked short of a decade for an offshore engineering company; a big part of that in the Innovation department, he decided to shift his attention to retail.  

Bassem is currently the lab manager of Airlab and responsible for the R&D portfolio of Ahold Delhaize. When not at work, you can find him trash-talking about beating you in table tennis, board games or video games and somehow losing every time…

Ir. Chadi Salmi
