Biography
I joined the University of Bradford in August 2022 as a Lecturer in Electronics and Software Engineering, a post affiliated with the Bradford-Renduchintala Centre for Space AI.
Before that I received a BEng in Telecommunications from the Technical University - Sofia, an MSc in Spacecraft Technology and Satellite Communications from University College London, and a PhD in Electronic and Electrical Engineering from the University of Leeds. I then spent several years there working as a postdoctoral researcher in the Institute of Robotics, Autonomous Systems, and Sensing.
I have worked on a wide range of single- and multi- disciplinary projects, all of which have involved the use of RF and wireless technology in one form or another. Some of these projects were:
- Cleanroom microfabrication of resonant-tunnelling diodes (RTDs) and MEMS structures
- Simultaneous Wireless Information and Power Transfer at 5.8 GHz and 24 GHz
- Additive manufacture of conformal antennas
- Implantable antennas for exploratory neuroscience studies
- Wireless communications for infrastructure robotics - Pipebots project
- Linear and non-linear design and simulation of RF/microwave circuits, components, and systems using Keysight ADS and Ansys HFSS among others
- Linear and non-linear RF measurements up to 100s of GHz, including S-parameter, modulated signal, and on-wafer probe measurements
- Dielectric material characterisation including soft biological tissue and custom fixture design
- Use of Software-Defined Radio for propagation measurements and wireless communication system prototyping up to 6 GHz
- Embedded electronics for wireless sensor networks, using MCUs like nRF52840 and STM32WB55
- Robotics-related hardware and software frameworks, such as BeagleBone and Raspberry Pi for embedded Linux, and ROS2, MAVLink, and ArduPilot for various robotics platforms
- General, scientific, and embedded programming in C and Python, including various frameworks and packages such as Jupyter, scikit-rf, gprMax, and others
I am also passionate about public engagement and outreach - I am an active STEM Ambassador with the Transpennine Hub, and was awarded an RAEng Ingenious grant in 2020/2021.
Research
My research interests are in the broad field of wireless communications and wireless electronics, particularly in the context of satellite communications. Particular projects and topics I am currently working on and interested in are:- Developing millimetre-wave transceiver hardware for nanosatellites
- Investigating the feasibility of mesh networks at millimetre-wave frequencies for robotics and satellite applications
- Use of COTS hardware for communication link impairments emulation
- Simultaneous communication and sensing
Finally, I am curious about similarities between system and component design principles for satellites and for other applications in resource-constrained environments, such as exploration robotics and implantable/wearable healthcare technology.
Teaching
Teaching interests
