Created a localized risk assessment model (LRAM) which is able to rank overhead lines based on a multitude of climate and utility factors.Used the LRAM to help prioritize grid modernization efforts to optimize the money spent and risk reduced.Utilized Bayesian models to predict outage events across our network based on forecasted conditions. Biased gridded forecasts with weather station measurements to increase agreement.Identified weather and vegetation conditions which necessitate a Public Service Power Shutoff event.

Jun 2017 - Sep 2017
Using random forests in Scikit-Learn predicted the error of nuclear criticality simulations on a large dataset (90,000+ features).Using feature importance measures identified isotopes and reactions of interest that could be increasing errors.Applied convolutional neural networks using the Pytorch package.Wrote a paper (now published) and presented at the 2017 International Conference for Transport Theory.Had to communicate the significance and validity of my approach to experts in the nuclear community who were not familiar with machine learning.

Oct 2014 - Jun 2017
Tour regional manufacturing facilities, collect data and prepare engineering recommendations for industrial clients to improve energy efficiency, reduce waste generation, and increase profitability. Draft energy assessment reports that include energy savings recommendations.Reports include energy saving recommendations and implementation costs, state and federal incentives, financial feasibility analyses, general background, utility analyses, common system best practices, and other relevant energy considerations.I managed Baseline operations, which entailed working with utility providers to obtain billing history, and then analyzing the bills to create future cost models.

Jun 2016 - Sep 2016
Created fixed source benchmarks for MCNP6, and compared results against analytic solutions using Python.Found an error associated with the flux tally at low grazing angles, which was patched in the new release of MCNP. Studied effect of S(α,β) special treatment in MCNP6 on criticality calculations.Prepared a summary paper for publication which was presented at ANS 2017 summer conference.

Jun 2015 - Jun 2016
I managed a project funded by the Student Sustainability Initiative, that aimed to reduce waste and promote holistic sustainability on the campus of Oregon State University. In the past, we have written recommendations that help the on campus power plant increase overall plant efficiency. Most recently, we did an economic analysis for installing solar panels and switching to LED light fixtures for student fee funded buildings.
