Since August 2023 I have managed the two teams of the OnePassportapplication which provides access to all enterprise RDS and DynamoDBinstances for the SCAN and Metabot applications.From May of 2022 to August of 2023 I managed six teams across fourapplications: Metabot (dataset inventory), Datastore Inventory, DataRetention, and Data Governance Suite.From November 2020 to May of 2022 I managed two teams for theprocessor and orchestration components of the SCAN application. SCANsearches for highly sensitive human data such as SSN, credit cardnumber, etc. in S3. In 2021 my teams successfully processed more than100 PB of data at a rate averaging 500 TB/day to satisfy a regulatoryrequirement.From March 2019 to November 2020 I was the technical lead for the LossForecasting solution used by the Credit Risk Management team forCard.

The Data Engineering team at Xometry is responsible for maintainingproduction quality code which handles or manipulates data. Our firstand current project is rearchitect Xometry's quoting flow such thatthe web client and geometry/pricing backend communication isasynchronous. In this role I manage two senior software engineers.

I lead the team that develops and implements the computational geometry algorithms to identify geometric features that drive the price of the parts. My team of 5 reports includes PhD and MSc level members with degrees in Computer Science, Mechanical Engineering, and Chemical Engineering with a focus in Computational Fluid Dynamics.In addition to managing the team, I architected the computational geometry application, and I developed the Docker-based deployment process of the application. Our app is a model of unit test coverage within the company. The geometry application is a key piece of the technology stack at the center of Xometry's value proposition.

Xometry is a manufacturing on demand startup -- our customers upload their CAD models, and our software analyzes the geometry and issues an instant quote for manufacture. Xometry quotes a variety of manufacturing processes including 3D printing, CNC machining, sheet metal, and a number of others. As Senior Computational Scientist, I wrote and architected the core of Xometry's geometry analysis application. Specifically, I designed and implemented the mesh class, the algorithms for CNC fixturing detection, the initial approach to analyzing sheet metal, and several of our design for manufacture (DFM) detection algorithms. I also created several of the concepts used to describe surface curvature and other inputs to Xometry's pricing algorithm.

At ARL I have investigated radioisotope batteries, namely betavoltaic and betaphotovoltaic devices. Our team demonstrated a working GaN based betavoltaic device -- I specified the structure, verified the devices using electron beam induced current scanning tunneling microscopy, and guided the devices through the various fabrication and characterization steps. For the betaphotovoltaic part of the project, I specified the AlGaN photovoltaic structure and developed a process of electrophoretic deposition to apply phosphor to the photovoltaic devices post-fabrication.In addition to the radioisotope batteries, I developed a model of electron transport through a thermoelectron energy conversion device featuring a negative electron affinity anode. The software I wrote for this project is used by university research groups and a startup company. This work was recognized by ARL as well as the official homepage of the US Army.

At CMU I was the lead postdoc on a project to develop a nanolithography technique using a scanning tunneling microscope tip as a stylus. During this time I built the TFAN nanolithography/surface science laboratory from scratch. This lab featured an ultrahigh vacuum surface analysis system including in-situ sample preparation, scanning probe microscopy, x-ray photoemission spectroscopy, Auger electron spectroscopy, and low-energy electron diffraction. I managed three graduate students and we developed processes to clean and hydrogen passivate Si (100), write features in the hydrogen passivation with the scanning probe tip, and adsorb disilane to the features.
