Open positions in cybersecurity, computer vision and urban informatics on drones

In fall 2020 we will kick off a new research venture, the ARROWSMITH project. Our research group has won the Smart City Cybersecurity Research Award granted by the Technology Innovation Institute (TII) in Abu Dhabi. The award paves the way to the new collaboration we will launch with the TII. We want you to be part of that journey. During the next 3 years we will look at cybersecure smart city solutions based on novel cryptography approaches, prevention of cyberattacks, machine learning and computer vision. Join us for the ride in Tampere Finland and the international global collaboration!

Open positions

We offer multiple (4-6) 3-year positions with a potential extension on levels of:

  • PhD candidates
  • Postdoctoral researchers

The positions will offer excellent opportunities to work in a team of professionals responsible for developing cutting edge computer vision, machine learning technology and cybersecurity at the cross-roads of practical smart city applications. We will use, for example, unmanned aerial vehicles for the data collection in the context of cities. The researchers will work together as a team allowing mutual learning and exchange of skills.


We welcome applications with any research focus related to cybersecurity, computer vision and machine learning. In addition, we are especially seeking candidates with the following research focus: 

  • Operations on encrypted data (SSE, FE, ABE)
  • Embedded security architectures
  • Computer vision and machine learning for drones
  • Urban informatics and 3D modelling

The successful candidates have strong programming and mathematics background. Experience in (or strong will to learn) programming with Python or C++/Java and skills in creating tools and extensions for deep learning and 3D visualization, are considered as advantages.

Teams and research

The Principal Investigators of the project are Billy Bob Brumley (Cryptography and cybersecurity, co-leading the [Network and Information Security NISEC Group](, Antonis Michalas (Cybersecurity), Harry Edelman (architecture, urban design and urban informatics) and Joni Kämäräinen (computer vision and machine learning). The PIs have strong experience on cryptography, cybersecurity, computer vision, machine learning, and urban design in smart cities. More information of our research is available on our web pages linked below.

Operations on encrypted data (SSE, FE, ABE)

We will be focusing on building lightweight cryptographic protocols that will allow constrained devices to communicate securely over possibly unsecure channels. In addition to that, we will look into ways of leveraging the power of secure hardware in order to design and develop protocols that will allow data processing (both in encrypted and unencrypted form) in a privacy-preserving manner. For more details, contact Billy and Antonios.

Computer vision and machine learning for drones

In this project computer vision provides data source for urban informatics, i.e. information about the users of urban areas. The urban area can be a limited region in indoors (accessible space) or outdoors (within GPS coordinates). Video streams are provided by drones that make the vision system active, i.e. it can move to capture more information. There are four fundamental problems addressed: 1) map the unknown region (pre-defined outdoor region or restricted indoor region) – metric and semantic mapping, 2) localize yourself in the given map, 3) detects objects (people, cars) and things (smoke, fire) and 4) localize the detected objects and things on the map. These provide tools for urban informatics such as “count people inside this region”, “deliver an item X to the location A”, “alarm if smoke detected in this region” or “calculate the green area in these blocks”. Our approaches to find solutions are based on the state-of-the-art techniques in computer vision, robotics and machine learning and we always seek better solutions using the cutting edge technologies such as deep learning and reinforcement learning. In the beginning of the project we will identify important and interesting sub-topics and we aim to publish ours works in the top-tier conferences of computer vision (CVPR, ICCV, ECCV, ACCV, BMVC), machine learning (ICLR, NeurIPS, ICML) and robotics (CoRL, ICRA). For more information, contact Joni.

Urban informatics and 3D modelling

Our main interest is to make urban design based on active data flows from the location. To that aim, we need to build digital content and semantic understanding of the spaces as a contextual settings for versatile behavioral events in architectural space, either in outdoors or indoors. The behavioral events, for example bicycling, can be detected, analyzed and visualized in the context of spatial model to understand and communicate the needs for design or management of urban space. People oriented cities call for in-depth understanding how people use the cities and what kind of cities appeal to people. For example, Jane Jacobs (1961) and Jan Gehl (2011) have used systematic observations to collect data about the use of the urban environment. Now, machine learning and IoT devices provide powerful tools for creating in-depth understanding about cities and ways to build livable and resilient environments.  For more information, contact Harry.

Embedded Security Architectures

We will augment drones with SoC-based devices and technologies for hardware-based security. We are looking for embedded security expertise, and an interest in tinkering with low-level software and hardware. We will utilize Trusted Execution Environment (TEE) technologies such as ARM TrustZone and RISC-V analogues. We are interested in its access control and Trusted Application (TA) features. Side Channel Analysis (SCA) on all levels is also a strong aspect — both physical channel (power, EM, etc.) and software-based (timing, microarchitecture, cache, etc.), applied not only to the crypto functionality, but general security and even Machine Learning implementations.

Host institution 

Tampere University is situated in Central Finland being a leading hub for engineering and technology in Finland.
