About

As a Data Science Professional with 2.5 years of experience in healthcare analytics and a strong academic foundation in statistics and machine learning, I am passionate about leveraging data-driven insights to solve complex challenges. My expertise spans statistical modeling, machine learning, and data visualization, with hands-on experience in Python, R, SQL, Tableau, and AWS tools. Currently, I serve as an Associate Consultant in Data Science at Trinity Life Sciences, where I design and optimize algorithms, automate statistical testing processes, and deliver impactful analyses like HCP targeting, epidemiology projections, and market landscape studies. My contributions have significantly streamlined workflows, reducing manual effort and enhancing efficiency. Previously at Wysa, an AI-based mental health platform, I applied advanced statistical methods and machine learning techniques to drive engagement, retention, and efficacy analyses. This included developing models for survival analysis and emotion word studies, culminating in a research paper published by the World Economic Forum. With a Post-Graduation Diploma in Statistical Methods from the Indian Statistical Institute and an M.Sc. in Statistics, I bring academic rigor to applied data science. My passion for innovation extends to NLP, healthcare analytics, credit risk modeling, and deep learning. Let’s connect to explore opportunities at the intersection of data science and impactful problem-solving.
