About

I hold the Chair in Computer Architecture at the QCE department. I am also honorary visiting professor at the Department of Computing of Imperial College since 2014. I am a member of the CogniGron Program Board at the University of Groningen.  

Previously, I held the Chair in Innovative Computer Architectures at the University of Groningen (August 2019 - June 2023) and the Chair in Computer Systems Engineering at Chalmers University of Technology in Sweden until 2015. I was a VP of Dataflow Software Engineering at Maxeler Technologies Ltd. in London (2014-2018) and in December 2017 I started Maxeler IoT-Labs BV in Delft and was its managing director until January 2020. Maxeler is now part of groq Inc.  

Between 2002 and 2011 I was a faculty member at the Computer Engineering section. I co-founded the master of science program in Computer Engineering and was its first coordinator. Prior to TU Delft, I spent close to 15 years in the computing industry in Bulgaria (Pravetz) and Netherlands (Pijnenburg Microelectronics & Software / CPS).

Research

My research interests include embedded systems design, computer architecture and micro-architecture, reconfigurable computing, hardware/ software co-design, VLSI design, and computer systems testing. Currently my research is on dynamic techniques to manage contemporary distributed memory systems for custom computing systems and heterogeneous multicores, application specific acceleration, and low overhead reliability techniques. All the above topics are in the context of the expected technology trends in the future when the quality of the available transistors is deteriorating while their quantity on a single chip keeps scaling up. These trends combined with the severe power dissipation constraints require novel, holistic hardware-software approaches and place new challenges to computer systems designers. A possible oversimplification of the problem is how to transform the available transistor quantity into affordable quality in respect to power dissipation per unit area and drastically reduce the required data center space. Needless to say that minimizing data movements at all system levels is a key to achieve the above goal. Getting serous about the data in rest and in processing is a key.
