We give a warm welcome to all to join the APNet, as we unite to become stronger, together.

Introduction

I am an associate professor at UTU, Finland, and hold an adjunct professor position at TU Delft where I lead the CRYPTAI Lab. I earned my PhD in Computer Science from CityU Hong Kong. I held several academic positions, including as an information science research intern at A*STAR, a postdoctoral researcher at Aalto University, and an academic visitor at universities, e.g., UCL and Northwest University. I was an assistant professor at the University of Surrey. 

Since 2020, I've gained significant recognition within the ICT communities. I've secured European funding for several high-impact projects related to ICT, serving as PI and accumulating over 2.5 million euros in funding. My research has led to real-world impact through collaborations, e.g., IBM, Fujitsu, NEC, BIBA, ATOS, with use cases. 

My research has earned over 7k+ citations (top 2% citation scientist). My works have been featured in top-tier conferences, e.g., USENIX, ACM CCS, NDSS, CVPR, SIGMETRICS, ESORICS, Asiacrypt, and many others, as well as in leading international journals, e.g., IEEE Internet of Things Journal, IEEE Transactions on Cloud Computing, IEEE TDSC, IEEE Transactions on Industrial Informatics. I've also delivered information keynotes to international conferences and received awards, e.g., distinguished reviewer, best research paper.  

A sought-after expert, I've been invited to serve on PC member, as General Chair, and as a Steering Committee member for renowned theoretical ICT conferences, e.g.,  USENIX, ACM CCS, EUROCRYPT, WWW, IEEE Euro S&P, ESORICS, IEEE CSF, PoPETs, as well as session chairs, keynotes for information topics. I also serve as an Associate Editor for prominent journals, e.g., The Computer Journal, IEEE TDSC. I've actively hosted and organized top-tier international conferences, brought academic and economic impacts to local communities, e.g., ASPLOS + EuroSys (above 1000 attendees), Euro S&P (above 250), ESORICS (above 350). 

I've contributed to ISO standards, as a member of the BSI (when he was in UK) and as part of the NEN committee 381027 "Cybersecurity & Privacy" in the Netherlands. I've also been invited to serve on research funding review committees and panels for NWO (Dutch research council) and other international funding bodies. As one of the founding members, I contributed to the development and settlement of APNet (a national network supporting assistant professors across the Netherlands).

I am a Fellow of The Higher Education Academy, UK, and hold UTQ certificate, the Netherlands. Since 2016, I've involved in designing, teaching, and evaluating MSc, Bachelor's courses, as well as supervising MSc, PhD theses.  

It is pleased to evidently witness that the group and myself have contributed excellence, over recent years, in teaching BSc/MSc courses and PhD supervision/graduation (e.g., 4+ BSc group projects, 30+ MSc theses, 4 PhDs - 3 graduated, 1 on the way of graduation), securing promising research funding - contributing to supports on admin and department wide travel funding, publishing top-tier conferences and journals (e.g., USENIX, NDSS, IEEE TDSC), promoting ICT community as chairs via renowned conferences (e.g., ACM CCS, ACM ASPLOS/EuroSys, IEEE EuroSP, ESORICS, IEEE CSF), boosting local economic and expanding local ICT collaborations via conferences' attendees, being TPC and associate editors for international conferences (e.g., USENIX, ACM CCS) and journals (e.g., IEEE TDSC, IEEE TAI), putting forward use cases/pilots to various European countries via projects (e.g., TANGO, ASSURED). The group's performance is phenomenal. I am very proud of closely working with all the PhDs and post-docs and excellent colleagues (e.g., Alex, Lilika and George).
