After my secondment in MINDEF, I am now back to resume my role in DSO National Laboratories.

An occasional contributor to The Neo Tokyo Project website and Facebook page.Coverage of events overseas (e.g. Comiket, MCM London, Hyper Japan), and in Singapore (Doujima, ICDS, AFA).

This was a secondment to broaden my exposure to the Defence Technology Community* (DTC). I was involved in a plethora of strategic initiatives and efforts ranging from strategic forecasting, framework development, to policy writing that this office launches in order to move the whole of the DTC towards the vision set forth for Defence Development.The exposure I've gotten from the work I'm involved in so far has presented me a very different perspective than my previous role. Strategic planning has called into use a vastly different type of thinking, one that summons creativity and sense-making in ways which I have not exercised before, to navigate boundless problem and solution spaces.*DTC consists of DSO, DSTA, CSIT, and MINDEF HQ offices (of which one of them is this office).

Engineer in systems engineering in the Electronics Systems Division dealing in Electronic Warfare (EW).I design EW systems, handle integration and testing, and work with other specialised teams or vendors for components/subsystems.I also particularly specialise in design to implementation, testing, and verification of algorithms that process direct digital RF samples (in GHz bands) to perform detection, evaluation, and response. These involve realtime DSP techniques implemented in (mostly) pipelined architectures with assurance of fixed low latency (ns to us timescale) response while handling multiple high bandwidth ADC streams (throughput on the order of 10s of Gbps each). I implement these designs on mostly (Xilinx) FPGAs and SoCs, and code directly in VHDL (and a bit of C where necessary) to ensure the design reaches optimal performance for the application required. Latest experience is with the Xilinx RFSoC.Redistributing constraints from one subsystem to another when it has hit resource limits is the delicate balancing act that is systems engineering, and this has been very engaging for me. Executing component/subsystem builds in parallel before design finalisation so that tight timelines and budgets can be met has been extremely challenging. The constant tug of war between design freezing for manufacturing and keeping flexibility to incorporate last minute changes due to unforeseen limitations (this is R&D after all) all while ensuring the project stays within budget continues keep me on my toes.Every now and then, you might be able to find me in DSO outreach efforts to recruit more R&D engineers and students keen on the DSTA Scholarship!
