Uncertain about survey plans, troubled in data cleaning, confused by model estimates, concerned with result interpretation, or struggling with plot beautification? I provide consulting services in data science and can solve your problems through all stages of quantitative research, from experimental design to report writing. Welcome to connect with me on LinkedIn https://www.linkedin.com/in/drjerrytao and schedule a free initial call at https://calendly.com/drjerrytao/data-science-consultation. Drawing from my expertise where data science, economic consulting, and transportation planning intersect, I am passionate about synthesizing state-of-the-art and novel techniques in data analytics and business intelligence.

A certified data scientist, I am proficient in data mining, pattern visualization, statistical modeling, machine learning, and geospatial analysis. Master's in Transportation Science from UC Irvine and alumnus at McGill & UW, I was a data analyst at Seattle DOT and an airport consultant. My projects have covered a variety of topics including causal inference, model development, variable importance, outcome prediction, price optimization, demand forecasting, system efficiency, customer satisfaction, and marketing effectiveness. I leverage sound economic theory, insightful research design, and advanced analytical techniques, such as permutation tests, bootstrap resampling, numerical simulation, parallel processing, time series, longitudinal-data analysis, discrete choice modeling, random forests, deep learning, and beyond. You can find example deliverables in my LinkedIn featured documents, which highlight my specialty of effective communication via professional writing, mathematical derivation, and uncertainty illustration.
