    I am a results-driven data scientist with over 10 years experience conducting full-cycle research projects and developing and managing data products. I have a PhD in Political Science and have been working as a research and statistics consultant for over 5 years. I’m well versed in both quantitative and qualitative methods--regression analysis, predictive modeling, dimensionality reduction, focus groups, content analysis--and research design. I am also fluent in a range of tools and software (including Excel, Google Sheets, Looker, R, Python, and SQL) Beyond a command of the must-have data science skills, I bring a background in teaching and training. This means I don't assume you know what I'm talking about, I'm very good at figuring out what you need and how to get you there, and that I know the value of prompt, thorough communication. I'm also a deeply curious person who loves to help clients problem solve, productize their data, and improve their business ops. If you are looking for a Data Scientist, Data Analyst, Statistician, or Digital Product Developer/Manager, I could be your person. This might mean cleaning and wrangling data, analyzing data and creating written reports, helping you understand statistics, creating graphics to help you tell a data story, or productizing your data catalog to help you sell to clients. Go ahead and reach out, or send me an invitation to your project. I'll get back to you ASAP! I look forward to finding out how we can work together to achieve your goals!
