Ujwal Gadiraju is an Assistant Professor at the Web Information Systems group of the Faculty of Engineering, Mathematics and Computer Science (EEMCS/EWI), Delft University of Technology. He is a Director of the Delft AI “Design@Scale” Lab. In addition, Ujwal co-leads the Kappa research line on Crowd Computing and Human-Centered AI at the WIS group. He is a Distinguished Speaker of the ACM.
Prior to joining the WIS group, Ujwal worked at the L3S Research Center as a Postdoctoral researcher between 2017-2020. Ujwal received a PhD degree (Dr. rer. nat.) in Computer Science from the Leibniz University of Hannover, Germany in 2017, and an MSc. Computer Science degree from TU Delft, the Netherlands in 2012. His research interests lie at the intersection of Human-Computer Interaction (HCI) and Information Retrieval (IR), with a special focus on Crowd Computing. Ujwal’s prior work in Crowd Computing has explored methods to improve the effectiveness of the crowdsourcing paradigm, running large-scale human-centered experiments to understand the interaction between humans and machines, and understanding the societal impact of algorithmic decision-making.
Ujwal’s work focuses on systematically leveraging the ‘hybrid intelligence’ obtained by combining humans and machines to solve a range of problems in HCI and IR. His current research agenda pertaining to Crowd Computing and Human-centered AI includes the following topics:
- [30.01.2021] Our proposal for a Delft AI Lab called ‘Design@Scale’ has been accepted. I will serve as a Director of the Design@Scale Lab, which focuses on Human-AI collaboration to design solutions for complex social problems. This lab is the product of a collaboration with wonderful colleagues from the Industrial Design Engineering faculty at TU Delft.
- [22.01.2021] Appointed as an ACM Distinguished Speaker. This is a great way to engage with emerging professionals, students and the public on a range of topics in Crowd Computing and Human-Centered AI!
- [08.12.2020] Awarded a 5,000 EUR seed funding grant from the TU Delft Safety and Security Institute to support the ground work in building Conversational Agents for Mental Health & Wellbeing. The team consists of assistant professors Dr. Trivik Verma from the TPM faculty and Dr. Derek Lomas from the IDE faculty. More on this coming up soon!
