Centennial, Co, Us

Led 3 person team in building and monitoring automated data pipelines, developing model prototypes, and deploying ML pipelines to support development and productionalization of battery charging technology. This role also includes substantial project management, team and tool development (eg, cloud infra/version control/dependency management), and collaboration with upper management on yearly strategic planning.

Centennial, Co, Us

Built and maintained automated and containerized data pipelines for pulling, cleaning, processing, and monitoring of timeseries and non-timeseries data related to lithium ion batteries.

New York, Ny, Us

Developed, monitored, and productionalized end-to-end ETL and ML pipelines for enterprise clients in the manufacturing, pharmaceutical, and technology space.- Developed and migrated ML worklows to the Dataiku DSS platform, including building connectors to various data sources (object storage, RDBMS, SFTP), optimizing computation engines ( Spark, EKS, in-database), and monitoring data quality and model drit.- Established strategy for adoption of new ML sotware platform and use case development for enterprise customers with 10-500+ users.- Built productionalized XGBoost classification model with automated data ingestion, model versioning/updating, daily batch predictions and real-time scoring via an api endpoint.- Co-designed technical upskilling roadmap for internal groups and trained 100+ users on ETL worklows, data science best practices, and model deployment.

My primary role is focused on development and adoption of advanced imaging technology into clinical workflow for proton therapy radiation treatment. I also work on hardware and software technology development, simulation and modeling, systems integration, mock treatment design, and development of software tools to improve both workflow and analysis.Specifics include:- Development, evaluation, and integration of proton radiography and proton tomography systems- Developed and run Monte Carlo simulations in C++ (Geant4) to model beamline kinematics, patient dose distributions, and prototype proton radiography system for clinical use- Extensive use of software (Python) for data analysis and visualization

Santa Clara, Ca, Us

I worked in R&D to develop and optimize processes for thin film modification of metals, semiconductors, and dielectric materials for integration into advanced logic and memory devices. This work targets node 7 through node 3 development. Specifics include:- Developing and executing experiments on capital equipment aimed at modifying the physical and electrical properties of materials- Analysis of material and device performance through various types of measurements, including, but not limited to: XPS, XRR, XTEM, EELS, SEM, SIMS, RBS, Vt, and Rs- Research into ion implantation and plasma based processing to achieve customer targets- Developing DOE using JMP to extract key process parameters controlling film modification- Writing patents (4 granted, 2 awaiting grant status) - Collaborating with several international institutions to understand fundamental properties of materials through both modeling and experiment

I developed DOE (design of experiments) for various semiconductor fabrication processes in addition to calibration and characterization of thin films.Current technical skills:• Device fabrication: photolithography, ALD, CVD, RIE, evaporation, sputtering, passivation, and wet chemical etches• Device characterization: Photovoltaic cells (PCE and EQE) , transistors (leakage and transfer curves), and FPGA based data acquisition • Film characterization: AFM, SEM, UV-VIS Spectroscopy, C-V, and 4-probe measurements• Fabrication and purification of carbon nanotubes followed by integration into various devices

My dissertation, titled "Nanostructured Carbon Nanotube-Silicon Schottky Junction Solar Cells", details my doctoral research on photovoltaics. The fabricated devices, which use a carbon nanotube film spray deposited onto silicon nanowires, demonstrate a modulated power conversion efficiency through electronic gating of the active area carbon nanotube film. A power conversion efficiency of over 15% is demonstrated.

Gainesville, Florida, Us

Taught both undergraduate lab and discussion sections for the UF physics department.

My research at SCIPP focused on two projects: 1) A feasibility of study using proton computed tomography to image a deeply embedded simulated tumor (done in collaboration with Loma Linda Medical Center), and 2) Analyzing the charge collection efficiency of irradiated silicon strip detectors for use in the ATLAS detector at CERN. These projects involved programming in C++ and ROOT, extensive electronics fabrication and troubleshooting, working with FPGA based systems for data extraction and analysis, and standard semiconductor characterization techniques (e.g. two probe measurements for capacitance).
