Personal Statement

I have a proven track record of driving impactful business decisions through advanced machine learning and artificial intelligence as a data scientist with over five years of experience across healthcare and technology sectors. 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.
