Personal Statement

I have a proven track record of driving impactful business decisions through experimenation, advanced machine learning, and artificial intelligence as a data scientist with over six years of experience across healthcare and ecommerce sectors. I am currently a Senior Data Scientist in the Marketing Analytics Department at Etsy, primarily responsible for Paid Social. In order to make sure our dollars are well spent, I partner closely with the marketing team to evalaute different marketing strategies and tactics on Meta, Google, Youtube, Pinterest, and TikTok. Due to the growing popularity of Bayesian testing, experiment design has become a rapidly evolving landscape, so I often leverage my acedemic background to keep myself abreast of the latest developments, developing novel tools such as a Bayesian Power Tool. At Ophelia, I was responsible for customer growth through ML-driven ad campaigns. As the first Data Science hire at a startup, I had to wear many different hats, including those of a data engineer and a marketing manager. At Healthfirst, I developed a novel Diabetes Preventable Admissions model, which received the highest individual contributor award.

I bring a unique blend of technical skills and strategic thinking. I am passionate about using data to solve complex challenges, and I am excited to bring this expertise to a forward-thinking organization where I can continue to make a tangible impact. As a psychology and creative writing double-major with a passion for data analytics, I am fascinated by emerging technologies, social dynamics, and out-of-the-box approaches to problem solving.
