Eric Bridgeford

Statistician & Project Manager

Hello! I'm Eric Bridgeford. I am a Ph.D. Student in the Department of Biostatistics at Johns Hopkins University. I am a Statistical Analyst focusing on independence testing, manifold embedding, and graph inference. I have a strong background in management and leadership of technical teams, and have a key interest in the integration of distributed computing and blockchain technologies into existing workflows.

demoEducation

Johns Hopkins University
B.S. in Biomedical Engineering and Computer Science
September 2013 - May 2017

I completed my undergraduate education at Johns Hopkins University, with my coursework focusing particularly at the intersection of statistics, bioengineering, and scalable computing.

Johns Hopkins Department of Biostatistics
Doctoral Student
September 2018 - present

I will be pursuing a Ph.D. in the Department of Biostatistics at Johns Hopkins University beginning this upcoming fall. My research will focus on graph inference with emphasis on mesoscale connectomics applications. I will be supervised by Dr. Brian Caffo, Dr. Joshua Vogelstein, and Dr. Carey Priebe.

demoExperience

Undergraduate Researcher
University of Pennsylvania
May 2014 - February 2016

With Dr. Bassett and Dr. Muldoon, I aided in the development of a novel network statistic, the Small World Propensity. Our statistic provides an extension of small worldness to weighted graphs, a common element of real-world networks, and robustness to changes in edge density.

Undergraduate Researcher
NeuroData
October 2014 - May 2017

With the NeuroData Team, I worked with Dr. Vogelstein to develop statistics for quantifying reliability in multi-scan scientific data and a processing pipeline for functional MRI connectomics to extend our existing pipeline for diffusion connectomics.

Research Scientist
Johns Hopkins BME Department
September 2017 - present

With Dr. Vogelstein, Dr. Caffo, and Dr. Priebe, I extended our MRI connectomics pipeline for hyperparallelizability on AWS architecture and developed theoretical methods/software packages for manifold embedding techniques, independence testing, and graph statistics.

atana
Vice President of Engineering
Atana
January 2018 - September 2019

As the Vice President of Engineering, I was responsible for contributing technological vision, coauthoring technical documents and patents, and managing the software and data analytics teams. I also managed the delivery of internal technical projects. The company has since re-focused as Trimwire by Atana, LLC.
