About

I am a researcher with a focus on high-dimensional statistical learning, large-scale distributed optimization, reproducible research, and data science.

I also have abundant knowledge on reinforcement learning, deep learning, operations research, economics, finance, sociology, and many other domains.

Meanwhile, I provide data science innovation consulting, designing for my clients tailored solutions to problems that cannot be solved with regular methods.

Get in touch with me if you want to know more about my research or are interested in my expertise.
