Ahmad Alnafessah

Short bio. I am currently a PhD student at the Department of Computing, Imperial College London. Previously, I was a senior academic researcher at National Centre for AI and Big Data Technologies KACST from 2012-2017. My research is on performance engineering for big data systems, with a specific focus on in-memory platforms. I am interested in big data systems, AI, IoT, HCP, complex distributed systems and cloud computing.

Lulai Zhu

Short bio.  Lulai Zhu obtained a BEng and an MEng in Measurement Technology and Instruments from Sichuan University, China, in 2008 and 2011 respectively. After that, he joined Emerson Network Power and had been working as a software test engineer for four years. He received in 2016 an MSc in Computing Science from Imperial College London, UK, and is now a doctoral student in the Department of Computing under the supervision of Dr. Giuliano Casale. His PhD study aims to contribute analytical methods for solving performance models such as queueing networks and Petri nets, with a particular focus on fluid approximation. He recently worked as a research assistant in the DICE project on performance modeling and simulation, and would play a similar role in the RADON project on architectural decomposition and optimization. He is also an active maintainer of the well-known JMT suite.
