About

Professional summary

I am an Applied Machine Learning Scientist and Data Scientist with a PhD in Computational Physics and more than nine years of applied machine learning research and production experience. I build scalable machine learning systems that turn complex data into measurable business and customer outcomes.

In my current work at TD Bank, I develop production ML for personalized ranking, recommendations, and customer decisioning. I use Python, SQL, PySpark, and Azure Databricks to create feature engineering, scoring, calibration, ranking, and evaluation pipelines at scale.

My core specialization is causal inference and experimentation, including uplift modeling, Double Machine Learning, experimental design, hypothesis testing, and offline and online evaluation. I apply these methods to personalization, revenue optimization, model benchmarking, and reliable decision-making.

I also have extensive research experience in computational modeling, financial machine learning, quantum machine learning, and scientific applications of AI. My work includes research on fairness and bias mitigation, and I have contributed more than 13 peer-reviewed publications and 20 conference presentations.

I enjoy collaborating across product, engineering, model validation, privacy, compliance, and business teams. I mentor researchers and students, communicate technical results clearly, and use modern LLM, RAG, semantic retrieval, and fine-tuning workflows to solve advanced data and modeling problems.
