• Job Responsibilities
• Operated in command and control element for large satellite constellation for low earth orbit (LEO) satellite fleet from simulated environment through launch and early check out phase (LEOP), and service.
• Supported real-time operations, monitored and maintained satellite health, implemented mission objectives, and troubleshot problems through root cause investigation, and corrective actions.
• Gathered technical and functional requirements for software corrections from live operations, worked with technical leads to determine application architecture, wrote Python scripts to execute commands to the.
• Designed engineering analytics for satellite state of health using Python scripts in Jupyter Notebooks that extracted live and back-orbit telemetry data from Elasticsearch databases, compiled data into pandas.
• Built power subsystem data visualization dashboards in Kibana and Grafana, which operators used to track vehicle state of health and troubleshoot hardware failures.

• Job responsibilities:
• Managed and operated analytical laboratory through standardized data collection, analysis, and documentation processes, enabling accurate reporting of progress and integrated management of laboratory.
• Wrote proposals and reports which significantly contributed to the successful award and completion of SBIR phase I and II contracts.
• Designed and developed materials starting from compositional modelling through fabrication and production, specifically articles of mechanical alloys, nanostructured material, metal matrix composites, bulk metallic.
• Compiled data in R and performed data analysis and plotting. Work on nano-grained high-strength alloy compositions resulted in the award of a major commercial contract.

Blacksburg, VA

• Job Responsibilities:
• Designed and executed experimentation for electrodynamics of nano-scale ferroelectric thin films and hydrodynamics of glycerol water mixtures.
• Developed experimental procedure to collect data on thin film samples heated up to 800°C using terahertz frequency band microwave probes.
• Measured dialectric response of nano-film with vector network analyzer.
• Designed sample preparation process that eliminated feedback in microwave probe holder, reduced sample volume required for accurate results, and increased quantity of samples measured per experiment.
