Projects & Industry Applications

Challenge

Manual rotation of quarter-wave plates and Glan-Taylor polarizers for polarization scans (±45° and full 360°) took over 2 hours per dataset, with inconsistent angular precision and high risk of human error.

Solution

Developed a Python-based GUI application (PyQt5) for automated hardware control, real-time power monitoring, and precise angular positioning. Inspired by self-referencing techniques for circular dichroism measurements, the system ensures reproducible polarization quality for twin-foci beam profiles.

Impact

• •Reduced scan time from 2+ hours to ~5 minutes (96% faster)
• •Eliminated manual positioning errors
• •Enabled multiple high-quality datasets per day instead of 1–2

Challenge

Time-resolved PEPICO experiments produce complex binary data from TDC acquisition. Manual conversion and analysis limited throughput and introduced inconsistencies.

Solution

Built a Python/Jupyter-based pipeline that converts raw TDC binary files to calibrated time-of-flight spectra, performs electron kinetic energy and mass calibration, coincidence analysis (TOF-vs-TOF), and statistical evaluation. Users specify data location and basic parameters; the pipeline handles the rest.

Impact

• •Processes multiple datasets reliably and consistently
• •Generates publication-ready plots and statistical summaries
• •Removes analysis as a bottleneck, experiment pace now drives progress

Challenge

High-throughput spectroscopic analysis requires processing 200+ spectra per day with minimal manual intervention.

Solution

Creating a robust, semi-automated workflow featuring automated baseline correction, peak fitting, machine-learning classification for material identification, outlier detection, quality scoring, and LIMS integration.

Impact

• •Reduce processing time from weeks to hours for large batches
• •Standardize analysis across datasets
• •Enable parallel research streams in materials characterization

Challenge

Manage a prestigious national fellowship (one of ~1,000 awarded annually in India) as principal researcher while completing PhD research.

Solution

End-to-end program delivery including annual financial reporting, procurement planning, progress tracking for government review, and multi-institution collaboration across Germany and India over 5 years.

Impact

• •Delivered 12 first-author publications
• •Contributed to one granted patent (gas-separation membranes)
• •Maintained regulatory compliance across 5-year program
• •Coordinated with stakeholders across multiple institutions

Challenge

In a shared ultrafast laser laboratory, scheduling conflicts, documentation gaps, and workflow handoffs limited overall productivity.

Solution

Team-based implementation of shared equipment booking calendar, standardized maintenance checklists, experimental protocols, and Obsidian-based shared lab notebook. Weekly planning meetings align schedules and priorities.

Impact

• •Improved equipment availability and reduced downtime
• •Enabled smoother onboarding and better collaboration through superior documentation
• •Increased overall group throughput (estimated ~40% from combined improvements)
