Hi my name is Dr Jonathan Smith and I am interested in machine learning and computational applications to real-world problems.
I have just accepted a Machine Learning Data Analyst position starting in January 2022 at the British Antarctic Survey. During this position I will help generate cutting edge data analytics techniques with an application to the Digital Twin of the RRS Sir David Attenborough.
I have just completed postdoctoral researcher position at California Institute of Technology investigating dynamics of earthquakes using cutting edge machine learning techniques. This work entailed computationally efficient research able to detect, associate and locate earthquake signals across 100's of TerraBytes of continuous realtime data. The work completed throughout this position combined a wide variety of machine learning and statistics based techniques, including but not limited to: Physics Informed neural networks, Neural Operators, Stein Variational Gradient Descent, Normalizing Flows, Recurrent Neural Networks, Convolutional Neural Networks, and conventional Deep Neural Networks. In addition, during this position I helped supervise students from the Computer Science and Earth Science for undergraduate, postgraduate and PhD projects.
I received my Doctorate of Philosophy in Geophysics from Hughes Hall, University of Cambridge, investigating 'Geomechanical properties of the Groningen gas reservoir'. This work combined extensive satellite and surface based remote sensing datasets (InSAR, cGPS and Optival Levelling), with regional earthquake catalogues, to better understand the surface and subsurface dynamics of active reservoirs, with the scope of forecasting the hazard of future production scenarios. During this position I also worked on volcanic hazard of central Iceland, providing infield knowledge of seismic network deployment, helping supervise masters student projects, and developing exhibits with demonstration for the 2016 Explosive Earth Royal Society Summer Student Exhibition.
EMPLOYMENT & EDUCATION
2022 - 2023
MACHINE LEARNING DATA ANALYST
BRITISH ANTARCTIC SURVEY
Generating cutting edge machine learning applications for use with the Digital Twin of the RRS Sir David Attenborough.
2019 - 2021
POSTDOCTORAL RESEARCHER IN SEISMOLOGY
CALIFORNIA INSTITUTE OF TECHNOLOGY
I have just completed Postdoc under the supervision of Prof. Zachary Ross investigating the improvement of earthquake detection and location techniques to better reconcile earthquake dynamics. During this employment we applied and developed cutting edge machine learning techniques, with applications including: Physics Informed neural networks, Neural Operators, Stein Variational Gradient Descent, Normalizing Flows, Recurrent Neural Networks, Convolutional Neural Networks, and conventional Deep Neural Networks.
During my position I worked closely with members of the Caltech computer science department, helping supervisor research projects of undergraduate computer science students.
2015 - 2019
DOCTOR OF PHILOSOPHY IN GEOPHYSICS
UNIVERSITY OF CAMBRIDGE
I completed my PhD on 'Geomechanical properties of the Groningen gas reservoir' under the supervision of Prof Robert S. White and Prof Jean-Philippe Avouac.
This project was funded in collaboration with SHELL Global Solutions and entails a close working relationship with SHELL Netherlands, for the integration of: induced seismicity location analysis, surface subsidence monitoring, and seismic probabilistic forecasting.
This work has involved me in coding development, multithreaded computational modelling, Bayesian statistical modelling, principal component analyses and data storage/manipulation of large datasets (>32TB).
2011 - 2015
MASTER'S DEGREE IN EARTH SCIENCES - 2:I
UNIVERSITY OF OXFORD
Awarded a 2:1 honours degree in Earth Sciences from St Edmund Hall, Oxford.
