   As a Director in PwC\'s NES practice, I apply statistical sampling across a wide range of business and regulatory contexts. I bring deep technical expertise in the design, execution, and interpretation of statistically valid samples delivering data-driven insights and efficient risk mitigation strategies for clients and internal teams alike.Tax Sampling: Design and defend statistically sound sampling methodologies for federal, sales & use tax, VAT, and other indirect tax filings or audits. Work directly with taxing authorities to support audit defense and resolve disputes efficiently.SOX and Internal Controls Sampling: Apply stratified and attribute sampling techniques to test controls across complex control environments, ensuring compliance and confidence in financial reporting.Advisory and Custom Sampling Applications: Consult on sampling strategy wherever it intersects with data-driven decision-making, including fraud detection, compliance testing, and process optimization.With a passion for demystifying statistics and empowering stakeholders through analytics, I aim to make complex data more actionable and compliance more scalable.
