Tobias Morville

PhD, MSc in Economics

Summary

Trained economist with a PhD in Computational Neuroscience. My background is technical with a intent focus mathematical modeling. I have 5 years+ experience with designing, developing and delivering machine learning solutions in academia and industry.

Specialized in

Mathematical modeling, machine learning in production, data science as a process.

Tech stack

Everything Python, Git, Docker & Linux. Learning Rails as a hobby.

Education

Nov 14 - Oct 17 Ph.D. in computational neuroscience, University of Copenhagen.

2010 - 2013 M.Sc. in Economics, University of Copenhagen.

2006 - 2010 B.Sc. in Economics, University of Copenhagen.

Key experience

Nov 17 - Senior Data Scientist, 2021.ai.

As a Senior data scientist I have three main responsibilities: 1) Design and develop machine learning models for various industry cases. 2) Write the software that support those models in production. 3) Design and document procedures and workflow around data science as a process.

Machine learning

Trained a churn model (XGBoost) on time-series data from three major danish unions (millions of rows, thousands of features) and built a framework (Dash) for explaining model predictions per member based on Shapely additive values.

Deep learning

Built a fraud-detection model (classification of graph embeddings using TensorFlow and Keras) on a graph that contained every single danish company and its connections.

General development

Built a end-to-end workflow based on Docker containers which allows for full unit-testing of deployed models, complete reproduction of experiments and system agnostic model deployment.

 

Nov 17 - May 18 Research Consultant, Danish Research Centre for Magnetic Resonance.

As a research consultant I managed one major experiment, did end-to-end analysis of neuroimaging data and helped write a scientific article on theory derived from my thesis.

Experimental

Design and execution of a fMRI experiment in which subjects were automatically fed small amounts of juice while interacting with a virtual game real time.

Image processing

Preprocessing and statistical analysis of behavioral and neuroimageing data (Python, Matlab).

 

Nov 14 - Oct 17 Ph.D. Fellow, University of Copenhagen.

My thesis is about how the brain computes reward. I developed a novel model for predicting dopaminergic activity, ran the experiment to test predictions and analysed the resulting data.

Theoretical development

Built a conceptual model of the reward system based on the free energy principle. Code up the circuit model of how this is implemented in the micro circuitry of the brain. The theory goes into detail with reinforcement learning, statistical physics and information theory.

Management

Design and execution of several major neuroimaging experiments, often requiring building custom pieces of electronics and managing research assistants.

Image processing

Built several pipelines (Matlab, Python) for analysis of behavioral and neuroimaging data. In summary, a mix of computer vision, time-series statistics and machine learning.
