Hayden Lee

Developed and maintained software systems for undersea sensor systems and sonar data processing. Engaged in self-managed research activities for generating synthetic audio data using generative AI technologies.

Key contributions:

• Leveraged Qt Framework to build a message logging system to record simulation events. Improved memory efficiency by storing messages as byte objects, and demonstrated OOP concepts to develop byte-parsing interface.
• Used Tensorflow to develop a Generative Adversarial Network (GAN) model to recognise audio data characteristics and synthesise realistic artificial data.
• Built and deployed a Docker development environment for cross compiling onto multiple different ARM architecture computers, leveraging containerisation for streamlined development.
• Collaborated with team members from project planning to executing effective git version control processes to provide technical support and communication.
• Worked in an agile environment and followed the scrum process to develop and maintain full-stack software systems.

Supported DSTG work programs by developing in-house software tools and undertaking simulation and analysis tasks in accordance with stakeholder plans and requirements.

Key contributions:

• Developed a Qt3D simulation visualisation GUI. Implemented a publish-subscribe design pattern using a custom abstract item model/view control architecture to reduce system complexity and ensure scalability.
• Directed and delivered a Monte Carlo study using design of experiments techniques to analyse statistical variance in torpedo performance, understand torpedo decision-making and behaviours, and build domain knowledge.
• Performed model verification by developing a submarine dynamics MATLAB model from first principles and comparing and contrasting its performance against DSTG's hydroacoustics capability.

Contributed to the design of the Australian Research and Experimental Submarine (ARES) at the University of Adelaide.

Key contributions:

• Engaged with stakeholders to generate system requirements to lead control system and control surfaces design.
• Developed and demonstrated a proof-of-concept onboard control system for depth-keeping using microcontroller technologies.
• Delivered technical specification and justification report for control system and control surfaces design.
