I am currently a data scientist at Yelp. Previously I was a data-driven neuroscientist at Caltech, where I imaged neural activity in fruit flies while they flew (flapped their wings, but were held in place by glue). I presented various visual and mechanosensory stimuli to flies using custom-built hardware, and I simultaneously measured their behavioral and neural responses. To acquire data I relied heavily on hardware from Phidgets, Arduino, Stock-drive Products, and other hobbyist places, as well as custom software written mostly in Python. These days, I analyze data almost exclusively in Python, relying heavily on Pandas, NumPy, Matplotlib, SciPy, and scikit-learn.
