Over the years and on both sides of the Atlantic, I've led a variety of quantitative & operational challenges across intelligent systems & software engineering, sonar, defense, environmental technology, robotics, and most recently the complex world of multi-channel retail.
The common thread linking passion, profession, and play is applying technology, good design, and quantitative modelling and simulation, to build better products, enable better decisions, and optimise performance.
Presently, I am Commercial Mathematician (aka data scientist) to a leading UK retailer, where I develop mathematical models and algorithms that get beneath a complex of systems, processes, and behaviours, to drive better performance for customers at a lower cost. My work is applied to demand forecasting, product replenishment, supply chain optimisation, statistical modelling of multi-channel behaviour, predictive analytics, as well as decisions around property portfolio transformation, merchandise ranging & assortments, and own-brand profitability.
Prior to this, I developed navigation & localisation algorithms for unmanned autonomous underwater robotic vehicles working for the ocean robotics R&D company Thalassa Autonomous Robotics Ltd. (Bristol, UK). This neat little animation illustrates the concept of what we designed for Undersea Oil & Gas Exploration. Videos of early prototypes in action are here, and here
In the U.S., I was the Director of Engineering & Operations at BioSonics, Inc. (Seattle, Washington), where I led the design, development and manufacturing of intelligent sonar systems and their real-time software. Applications spanned a number of industries including environmental monitoring of the world's first underwater tidal energy grid in New York City's East River, homeland defense with Sandia National Labs & the Naval Underwater Warfare Centre, and off-shore aquaculture (automated fish farming) with the Chilean government, among others.
I'm always experimenting and tinkering, so feel free to get in touch with ideas.

Or, how the Fermi GBM (gamma-ray burst monitor) turned out to be wrong on a result with confidence 3σ.
Photonic propulsion however, is not without its own laws-of-physics constraints. Using an equivalent amount of propulsive energy as currently used in a Mars rocket, and accelerating a similar sized manned craft would still require one month to reach Mars, an 83% reduction in transit time, but not quite as swift as two days...

"Euler learned at the feet of Johann Bernoulli, who had Euler "read the masters". Euler read difficult mathematics and Bernoulli helped him when he got stuck. In his later years, I propose that Euler was able to teach in the style under which he himself had learned. He had learned guided by the principle "Read the masters". He taught under the style "Read me, read me. I am Euler and I am your teacher in all things."

 Neils Abel, his student years:
It's an excellent example of a mathematical argument to a non-mathematical question.
A part of the argument:
In the past 80 years, "the [electromagnetic] noise we make as a society" has reached out 80 light years to reach only 2,326 confirmed exoplanets, and just 1/8 of one percent of our Milky Way. To put it into perspective, it would take 1,500 more years before our broadcasts have reached 50% of the Milky Way. (The time for the return communication is baked in, as it is not assumed that extra-terrestrial intelligence is exactly at the end of this distance, but could be anywhere in between.)
But there's more, covering interesting facts about the first broadcast to reach space (unfortunately Hilter's 1936 address), the first signal powerful enough to last close to 10,000 years (1974), why random electro-magnetic signals are not naturally occurring so that detecting them would be of sufficient curiosity despite not being able to decipher them, how SETI is sending mathematically oriented broadcasts as opposed to information encoded images speech or video.

Overlaid on this is the behavior of the Federal Reserve in controlling the money supply and cost of money by adjusting the federal funds rate (blue curve). This in turn sets the interest rate a commercial bank will offer on savings account deposits.
Notice prior to each crash is a strong spike in the funds rate. This is the Fed's attempt, by raising the cost of money, to sharply decelerate an overheating economy. The point is that while the specific trigger point of the crash may be somewhat arbitrary, the circumstances creating the conditions for the crash are not.
The crash that follows brings uncontrolled, severe deceleration to the economy as unemployment jumps. With this comes economic contraction as spending is curtailed and personal saving rate rises. In response, the Fed drops the funds rate drastically, loosening the flow of money as stimulus to counter the shock.
This can be seen in the graph, looking at the three curves, and observing how they move in the approach to- and recovery following each crash.
Judged against the past 60 years, the trailing six suggest we are in new territory. The federal funds rate has been flat lining just above 0% for an unprecedented 6 years. Though employment has recovered from 10% in 2008 to 5% in 2016, the personal savings rate continued to climb for the first half of the recovery and has only recently held firm at 5% in the second half of the recovery, but has not been shown movement down to pre-2008 2.5% level.
The dotted curves show that conditions appear to be ripening. Under the prolonged loose monetary policy, investments have not suffered. Indeed, the Dow Jones is at an all-time high (orange curve), consumer sentiment has been rising steadily toward past highs (blue dots), and home price annual growth rates have been on the upward march for the past few years (purple dots).
The question is whether a sharp rise in the federal funds rate will auger or itself trigger the next crash. A tipping point may well be November's election...
