Mathematician & Data Scientist

Toby Shearman

As an applied mathematician, I thrive on tackling challenging problems and communicating their solutions, relying on numerical computation and visualization to inspire rigorous mathematics. With over four years of experience as a data scientist, I leverage my expertise to translate strategic business motivations into mathematical formulations and extract actionable insights using visualization and modern computational frameworks.

Expertise: Optimization, Calculus of Variations, Materials and Multiple-scale Analysis, Uncertainty Quantification, Computational Geometry, Causal Inference and Machine Learning, Data Visualization, Distributed Computing, Petabyte-scale Data Analytics.

Experience

July 2021
Epsilon
Director

Manage a team of data scientists using the Scrum methodology to continually develop and deliver scalable and performant machine learning platforms on-time, communicating results directly to VP and SVP stakeholders.

Epsilon
Associate Director

Propose, design, and implement state-of-the-art machine learning tools to extract business insights at the scale of billions of customer-client interactions per day:

  • Causal inference methods measuring and optimizing the impact of digital advertising
  • Deep learning to understand the path-to-conversion
  • Game theoretic ideas attributing purchases to advertising
  • Petabyte-scale, distributed computing
Apr 2019 - Mar 2020
Epsilon
Senior Scientist

Redesign existing Scala and Python source:

  • Reducing overall resource usage by over 50%
  • Reducing source lines and complexity by over 70%
  • Greatly expanding platform expressiveness and reducing time-to-launch of new products

Organize and curate weekly journal club to keep the department up-to-date on modern techniques and establish shared fundamentals

Aug 2017 - Apr 2019
Epsilon
Scientist
2013 - 2014
Center for Nonlinear Studies, Los Alamos National Laboratory
Graduate Research Assistant

Developed and implemented modern machine learning algorithms to accelerate and to reduce the cost of materials discovery. Focusing on functional materials like piezoelectrics, combining materials science, geometrical and structural data and DFT simulations, we proposed novel materials for synthesis.
