    I graduated with a BS in Applied Mathematics/Statistics from San Jose State University. I have a strong background in quantitative science through my degree and previous experience working with raw data at the Shaffer Avian Physiology and Ecology Lab. In addition, my data science skills were sharpened through the Applied Data Science Program, where I gained hands-on experience in data cleaning, data analysis, and statistical analyses. My capstone project challenged me as my objective was to build a regression model that accurately predicts the target variable. I successfully interpreted patterns in the data, created a Random Forest model that accounted for 97% of the variance in the target variable, and prepared a summary analysis that featured crucial findings and actionable recommendations. Through my past experience, I have built and exercised my theoretical foundation and practical knowledge of data science. I invite you to look at my profile for further details about my experience.

    As a Rhodes Scholar with a doctorate in theoretical physics from Oxford University, I am well versed in both the scientific and creative arts. Whether your project requires an analysis of data, a design of apparatus, or a literal presentation of information, you can put me to work with confidence that the final product will exceed your expectations. My publications appear regularly in reputable journals and cover a wide range of topics. My consultancy Alphawave Research can help you address many of your technical needs, whether academic, commercial, or industrial, on a tight schedule and with spectacular results. What I practice is best described as inductive reasoning, otherwise known as inferential statistics. Inferential statistics encompasses both descriptive statistics (e.g. hypothesis testing) and predictive statistics (e.g. forecasting). A good description of what I do is found in D. S. Sivia's Data Analysis: A Bayesian Tutorial. That book is a quick read and easily skimmed, so if you can find it in your library or bookstore, please have a look at it. If you like what's going on there, you'll like what I can do for you.
