I am a data scientist who uses analytics and machine learning to drive innovation with applications in energy, the environment, transportation, and IoT. I implement a variety of machine learning techniques, spatio-temporal statistics, and numerical simulations to discover relationships in the underlying data and to build predictive models that can turn insight into actionable intelligence. I'm currently with the National Renewable Energy Lab in Golden, CO.
I have been part of a group of researchers at NREL who are building up computer vision as a core competency at the lab, with a large focus on transportation research projects. Currently the largest focus is implementing some deep learning algorithms for counting cars and trucks from existing traffic camera infrastructure. These counts are being used to improve traffic volume and energy consumption estimates for the city of Chattanooga.Computer Vision, Neural Networks, Transportation
The Eagle supercomputer at NREL is the most energy efficient supercomputer in the world. However, we want to make the system performance even more optimal. Collaborating with Hewlett Packard Enterprise, we are implementing algorithms to detect anomolous hardware activity and to perform power-aware job scheduling in an effor to further increase the energy efficiency of the system.AI, HPC, Energy, Machine Learning
Traffic congestion is not only an inconvenience to many of us, but also a major source of pollution and unnecessary energy consumption. In this project, my team at NREL is collaborating with scientists and developers at Oak Ridge National Lab to develop a situational awareness tool for the City of Chattanooga to monitor the latest traffic situation and to optimize traffic mitigation strategies in near real time through simulation and machine learning. Our optimized control strategies aim to reduce energy consumption by 20%.Transportation, Energy, Simulation
When a new wind plant is being considered for construction, a necessary first step is to assess the potential long-term power generation capabilities and sources of uncertainty. However, there are considerable differences in how consultants assess the potential performance considerations of a new wind plant. In this project, our team at NREL is developing a set of open source tools to drive standardization in the industry and to identify areas of improvement in these pre-construction estimates so that wind plant operators can maximize their expected profit margins.Energy, Renewables, Open source
Distribution network operators (DNOs) face enormous pressure to properly prepare for widespread power outage events, which are mostly due to big storms. In this project, MeteoGroup partnered with DNOs in the UK to develop advanced machine learning models that leverage our weather data and forecasts by predicting the expected volume of weather-related network faults. This product is currently being developed for operational use.Energy, Machine Learning, Data Science
In this research project I created a sample dashboard for monitoring data from a simulated sensor. The dashboard allows the user to generate new data, test how different linear model fitting techniques change with degrees of freedom, and to investigate the limitations of using certain linear models for predicting future sensor values.IoT, Anomaly Detection, Trend Analysis
Ski resorts depend on a reliable amount of artificially-generated snow for their daily wintertime operations. However, the quality and quantity of artifical snow generation can vary significantly with the ambient weather. Together with the Research & Innovation division of MeteoGroup and TechnoAlpin, we demonstrated our ability to save more than 100€ per snow cannon per day by using hyper-local weather forecasts to optimize snow generation times.Weather Forecasting, Optimization, Snow Cannons
All cars since the mid-1990s have been equipped with sensors to measure the vehicle's 'diagnostics. Modern vehicles record information from significantly more vehicles. I am actively working with data from connected cars and from simulated vehicles to identify features about the roads from driver-generated data. The above animation shows data from cars in Ann Arbor, MI and demonstrates how windhshield wiper activity compares to weather radar intensity.Connected Cars, Transportation, Big Data

PhD, Oceanography • 2013 My dissertation work investigated the circulation of coastal ocean waters in the Northeast Gulf of Mexico. The work used an understanding of ocean physics to understand how the larvae of gag grouper could be transported from deep waters to shallow coastal waters. I used numerical modeling approaches with a high-performance computing system. My primary advisors for this work were Dr. Eric P. Chassignet and Dr. Steven L. Morey.
