Hello, I'm
Antonis
Michalas

Assistant Professor in Cyber Security

About

I received my PhD in Network Security from Aalborg University, Denmark and I currently work as a lecturer in Cyber Security at the University of Westminster, London. As a lecturer I am teaching both undergraduate and postgraduate courses related to cryptography, forensics, cyber security and network security. My role expands to student supervision and research group coordination. In parallel I am an active member of the department’s project development and research activities.

Earlier, I was working as a postdoctoral researcher at the Security Lab of the Swedish Institute of Computer Science (SICS) in Stockholm, Sweden. As a postdoctoral researcher at the SEC Lab I was actively involved in national and European research projects and combined research with student supervision and project management.

I have published a significant number of papers in field-related journals and conferences and I have participated as a speaker in various conferences and workshops. My research interests include private and secure e-voting systems, reputation systems, privacy in decentralized environments, cloud computing, trusted computing and privacy preserving protocols in participatory sensing applications.

SICS

Postdoctoral Researcher

01/2014 - 09/2015

Actively involved in the current national and European research projects in the Security Lab, where I combine research with student supervision and project management. Within one year of starting at SICS, I have successfully obtained funding for three EU projects. Currently, I conduct research in the field of Security & Privacy for People-Centric Sensing, Cloud Computing, Trusted Computing, e-Voting Systems and Secure & Privacy Preserving e-Health Systems.

Hellenic Army,
Cyber Defense Department

Security Consultant

2013 - 2014
Responsible for implementing and managing an information encryption system for the specific needs of the Hellenic Army. My work involved designing a secure single sign on protocol which connects online services of different web applications used by the military personnel. Additionally, I was tasked with improving the security of existing systems/applications by staging attacks and providing solutions for any discovered vulnerabilities.

Education

University of Aalborg

PhD in Network
Security

2009 - 2013
I received my PhD from Aalborg University, Denmark in the field of Network Security with a focus on Privacy, Trust and secure e-Voting in distributed environments. In addition to my academic research experience, I participated in numerous external activities. In the summer of 2010 I participated in a summer school entitled: “Mobile systems and eHealth security” that took place at the University of Agder, Norway. From April 2012 until May 2012, I visited Ben Gurion University in Beer-Sheva, Israel while from June until August 2012 I visited the department of Electrical Engineering at Princeton University as a visiting student research collaborator.
Athens Information Technology

Masters in Information Technology & Telecommunications

2006 - 2007
Having acquired my undergraduate degree in Mathematics at the University of Crete, I later on completed my postgraduate studies at the Athens Information Technology in the field of Information Technology and Telecommunications, where I was awarded a Master of Science

Main Academic Interests: Computer Security, e-Learning, Web Technologies, Semantic Web.

University of Crete

Degree in
Mathematics

2000 - 2006
In the course of my undergraduate studies, I participated in numerous projects involving, in addition to pure mathematics, experimental control and IT implementation. Moreover, I had the opportunity of participating in a number of Applied Mathematics courses (i.e. Number Theory, Discrete Mathematics, Probabilities). This enabled me to enhance my knowledge and further develop my ability to utilize pure mathematics in programming.
