I worked at IFIS from 2008 to 2016. Currently, I am an Assistant Professor at Web Information Systems Group at TU Delft.
My research focus is on exploring novel human-centered query paradigms (like analogy queries), incorporating crowd-sourcing into information systems research, applications of novel query paradigms in e-commerce and e-business, and database query personalization (e.g. Skyline queries).

Have a look at our new poster gallery to give you an idea:

• Analogy-Enabled Informatin Systems
• Cooperative Query Personalization using Perceptional Similarity

Projects

(2012-2015) in MovieExplore - Discovering Movies in a Human-Centric Fashion

project management

This project focuses on discovering the perceptual properties of movies (and also other experience items) for enabeling human-centric interaction paradigms. This will allow users to interact with complex product spaces in a more natural and easier to understand fashion.

(2015) SQL-Alchemist 

project management

This project is funded by the presidential office of TU Braunschweig in order to foster and encourage innovation in university didactics. In this project, we develop novel concepts for teaching relational query languages like SQL, unifying approaches from modern didactics with mobile gamification. The goal of this project is to develop and establish a “serious” online game for supporting the B.Sc. lecture “Relational Databases 1”

(2013-2015) Anaqonda Project - Analogy Queries by Ontology-based Data Analytics

project management

The Anaqonda project deals with intelligent queries und personalization, and focuses especially on analogy queries. This project was funded by DAAD and executed at NII Tokyo.

(2006-2010) APIS - Advanced Personalization in Information Services

project member

The APIS project (Advanced Personalization in Information Services) investigates the impact of personalization technology on future information provisioning. Being interdisciplinary between computer science and cognitive sciences a basic belief of the APIS group is that modern information provisioning needs advanced query processing and optimization techniques using and understanding human preferences, usage patterns, conceptual views and (domain) ontologies. At the same time the architectures for information provisioning have to move from monolithical database systems to more open service-oriented infrastructures.
Source Code for our Skyline Simulator & Datasets can be found here.
