I am a first year PhD student in the CDT Pervasive Parallelism at the University of Edinburgh. My PhD is supervised by Dr Christophe Dubach and co-supervised by Dr Michel Steuwer; I am a member of the Lift research group.
The goal of my project is to bring performance portability to deep neural networks (NN). The approach is three-fold: abstracting NN implementation from hardware by expressing NNs in a functional language Lift, encoding generic and NN-specific optimisations as rewrite rules and producing corresponding OpenCL kernels. This methodology removes the need for expensive manual tuning of NN implementations to target hardware, and allows compiling NNs for a wide range of OpenCL-supporting GPUs and CPUs. High performance is delivered using such optimisational methods as memory access coalescing, parallel mappings space exploration, faster memory types exploitation, neuron pruning, approximate computations using weight quantisation and convolutional kernel singular-value decomposition. For more information, see my research poster and project page.

Research poster #2
Research poster #1
In 2016, I organized a workshop in a scientific summer school, where we built four auto-aiming catapults with a group of 16 years-old students.
The catapults are based on Arduino Uno, Tamiya Twin-Motor Gear Boxes and HC-SR04 ultrasonic sensor; the frame is made of plywood.
The goal of the workshop was to learn how to operate the wood workshop tools, and learn the mechanisms of motors, microcontrollers and ultrasonic sensors.

A GPU-Accelerated stigmergic BCMM swarm
This is my diploma project called “A GPU-Accelerated stigmergic BCMM swarm”. In short, it is a Python maze solver, that simulates a swarm on GPU using OpenCL. Swarm agents use neural networks to navigate in an unknown environment.
The project was developed using Python 3.4.2, OpenCL 1.2 (the code should be 1.0-compatible), PyOpenCL, Pygame, Numpy and FFmpeg. The platform is 64-bit Windows 7 and AMD Radeon HD 7870.

Raspberry Pi project
I participated in the York Raspberry Jam & Maker Event at the National STEM Centre. Together with other CS students we presented our raspberry projects, which we delivered for the “Raspberry Pi in the classroom” event — the idea was to design projects which could be repeated in schools with children learning to use Scratch on the Pi.
The video above is a demo of my project called “Magnetic checkers” – the goal was to move metallic checker pieces around the field using an electromagnet. The machine ended up resembling a simple 3D printer: 3 stepper motors, one moving base in axis X, two moving the head (magnet) in Y and Z axes. Software allows user to control machine manually and give simple tasks for automatic control (i.e. “move piece from A2 to E7”).
Software: Scratch for high-level control, Python for sending high-frequency PWM signal to GPIO pins.
Hardware: Meccano structural parts, x3 NEMA 17 motors, x3 A4988 Pololu drivers, 12V 6W electromanget, Raspberry Pi, 3 PSUs.
Pololu 3pi robot simulation
The individual part of the Pololu 3pi robot group assessment: it is a Matlab simulation, which interacts with robot’s C program by feeding it sensor readings in exchange for motor commands.
