Software and Programming : MATLAB (PLS Toolbox), JMP, In-House chemometrics software, Python

Key Roles:

  • Method Development and Validation : Developed and validated analytical methods for the characterisation of in-process and final drug products/substances/APIs by spectroscopic and thermal technologies
  • Regulatory Studies : Executed similarity assessment, reverse engineering and investigation studies on pharmaceutical products and substances while adhering to Good Manufacturing Practices (GMP) and audit compliance - contributing to efficient drug filing and defficiency responses
  • Bio-Catalytic Studies : Developed and optimized bio-catalytic (enzymatic) methods to monitor the dissociation of drug-products by DLS to improvise regulatory compliance and support other characterization techniques
  • Advanced Analytics :

1. Conducted exploratory data analysis (PCA, K-nearest neighbours, hierarchical clustering, etc.) and predictive modelling (SIMCA) to assess the similarities between in-house and reference-listed drug products and establish similarity criteria

2. Developed machine learning-based XRD data analysis pipeline (preprocessing, PCA , clustering) using in-house analytics software for trace polymorph detection—reducing manual analysis efforts by 80%

3. Used python packages such as pandas, numpy, scipy, lmfit, matplotlib etc to investigate and visualise spectroscopic data by X-Ray Photoelectron Spectroscopy
