Dr. Ferdous is an Associate Professor at the Department of Computer Science and Engineering of the BRAC University, Dhaka, Bangladesh. He is also an Honorary Research Fellow at the Institute for Security Science and Technology of Imperial College London. 

Previously, he was an ERCIM (European Research Consortium for Informatics and Mathematics) Alain Bensoussan Research Fellow at Fraunhofer Institute for Applied Information Technology (FIT), Sankt Augustin, Germany. During this one-year research fellowship he researched on Self-sovereign Identity Management using Blockchain Technology. He was supervised by Prof. Wolfgang Prinz. 

Previously, he was an Assistant Professor at the Department of Computer Science and Engineering of the Shahjalal University of Science and Technology (SUST), Sylhet Bangladesh. During my SUST tenure, I established the first-ever blockchain-focused security research laboratory, called SUBSEL (Shahjalal University Blockchain and SEcurity Laboratory), in Bangladesh at SUST. Before joining SUST I worked as a Research Associate at the Centre for Financial Technology of the Imperial College Business School, Imperial College London, UK. I was involved in a project in collaboration with Citi Group to explore how the blockchain technology could be leveraged to improve email security for any global financial institution. I am still associated with the Centre to continue this research remotely from Bangladesh. 

While at Imperial, Dr. Ferdous had the opportunity to work at the UK Cabinet Office as their first Technology Fellow. He was a part of a joint-project involving the UK Cabinet Office, UK Ministry of Justice and UK Police in which I explored how the blockchain technology could be leveraged for securing digital evidences. He designed and developed a proof of concept which the UK ministry of Justice exploring the possibility for real-life trial. This has been a very successful project and it received world-wide media attention. Please check the Media link to view a few media coverages. He worked as a Research Fellow at the Electronics and Computer Science of the University of Southampton in a Horizon 2020 cloud security project called SUNFISH in between September, 2015 to June, 2017. In this project, it was investigated how the blockchain technology could be exploited to increase the security in a cloud federation. He was a Post-doctoral Research Assistant at the School of Computing Science of the University of Glasgow in a project called the Integrated Multimedia City Data (iMCD). This was part of an ESRC funded Urban Big Data Centre, Glasgow under the umbrella of Big Data Theme. He was responsible for conducting research and developing systems for collating a large collection of textual and multimedia data from online news sources, microblogs, social sharing sites such as Youtube & flickr and wearable sensors such as life-loggers and GPS devices and then to analyse this data set to make sense. 

Dr. Ferdous was a SICSA (Scottish Informatics and Computer Science Alliance) Funded, PhD student at the University of Glasgow. My thesis title is User-controlled Identity Management Systems using Mobile Devices in which I investigated how modern smartphones, ever increasing in power and size, could be used for managing our online identities. My primary supervisor was Dr. Ron Poet and secondary supervisor was Dr. Gethin Norman.

Dr. Ferdous actively advise the Government of Bangladesh and different other Bangladeshi organisations in different capacities, particularly in Blockchain. He is the principal author of the National Blockchain Strategy document of Bangladesh.
