プロフィール概要

At the European Space Agency, I was tasked with researching relevant literature on a mathematical framework from the 1980s for understanding ocean circulation. My role was to update that framework given the numerous techno- logical advancements in data collection, validation and satellite remote sensing. Prior to me, a non-scientist software engineer had developed a rudimentary soft- ware for implementing the framework. Based on that software and other prior work done on the topic a Journal article was written, however, it was rejected. I was told that I needed to; 1) overhaul the software that was written (in a scientifically sound way). 2) develop machine learning or statistical modelling techniques to asses the uncertainty each dataset had on the final result we re- quired. 3) develop a user interface which would allow for the tool to be used by non-technical staff for research and validation purposes. In carrying out the three aforementioned tasks, I found that the code had a bug in which certain areas of the ocean experienced unrealistic values. This was only identified by looking at the code and its output in a scientific rather than a purely software driven way. Once the bug was found I was ready for the statistical aspect of understanding how uncertainties propagate to the final results we desired. For this, I implemented a Monte Carlo simulation which ran the model for hundreds of instances of each dataset within a set range of uncertainty found through validating the datasets against ground-truths. After this, I implemented a computer vision algorithm which detects patterns in the dataset space and produces maps based on the patterns. The results were unexpected and I was given the option of presenting the work at a scientific congress in Germany. It turned out that the session organ- isers at the congress selected my work as particularly societally relevant and so invited me for a longer presentation with an accompanying article to be pub- lished in their conference proceedings. As such, I had to refine my scientific and technical writing skills to appeal to the interests and needs of the wider scien- tific community. My work paid off with my paper and presentation winning an award for the best paper and presentation by a student, securing future funding and renewing interest for the project. However, it also proved that the work I had done along with the addition of statistical techniques had major societal impact. With the positive feedback from the conference, I set to work on writing a full scientific paper to be published in a high-ranking journal. I found that a lack of statistical analysis of the results and an error in one of the mathematical formulas was the reason for the past rejection of the paper. Once these were addresses (using the Monte Carlo simulation and computer vision approach), I began writing the paper. The journey of writing a full scientific paper required a high level of attention to detail to make sure the analysis, mathematics and implementation were all sound and correctly formulated. It also required that I reflected on the hypotheses and purposes of the study to target the correct journal (which is just as important as the study itself). In the end, the paper was published and the work was a success resulting directly in my PhD. The whole journey taught me numerous skills and the importance of correctly analysing data to prevent biases or incorrect conclusions to be drawn. For that, being critical of my own work was key to ensure a high- level of quality, mathematical and programming rigour to develop statistical techniques and algorithms to extract patterns which truely exist within the datasets.
