Dr Erika Sanchez-Velazquez

Senior Lecturer

Faculty:Faculty of Science and Engineering

Department:School of Computing and Information Science

Location: Chelmsford

Areas of Expertise: Cybersecurity and Networking , Internet of Things

Erika leads our Cisco Networking Academy and has expertise in networks and security. She has a special interest in recently developed technologies, include Software Defined Networks and the Internet of Things, with a focus on how they can improve security and how they affect the security of a network.



Erika has been an active academic and researcher for more than ten years, focusing primarily on computer networks and security. Her research career started with the creation of intrusion detection systems by analysing source code, then shifted into the definition of secure protocols for mobile and wireless communication, as well as intrusion detection techniques for mobile and wireless networks based in the Mobile-IP protocol. 

Erika's current areas of interest are software defined networks, and the definition of new protocols within the paradigm of a single controller within the network, and the security of the Internet of Things. She is currently a member of our Virtualization, Simulation & Infrastructure Research Group, where she's in charge of supervising several undergraduate, MSc and PhD dissertations.

Research interests

  • Software Defined Networks: in this new paradigm the control plane (which decides how to handle traffic) separates from the data plane (which forwards traffic according to decisions that the control plane makes). Erika’s interest is to implement a Cisco® One PK-based test bed and analyse the performance and security of a variety of protocols.
  • Internet of Things: with the statement that by 2015 more than 25 billion devices will be connected, it has become necessary to analyse if proposed networking and security solutions will be able to take the challenge. Erika’s interest is to design solutions based on IoT and analyse their security and performance in the connected world.
  • Member of the Virtualisation, Simulation & Infrastructure Research Group at Anglia Ruskin.
