Welcome

I am Alex (Oleksandr) Polozov, a senior researcher in the GRAIL (Grounded Reasoning and Interactive Learning) group at Microsoft Research AI, Redmond. I work on neural program synthesis from input-output examples and natural language, intersections of machine learning and software engineering, and neuro-symbolic architectures. I am particularly interested in combining neural and symbolic techniques to tackle the next generation of AI problems, including program synthesis, planning, and reasoning.

My main passion of the last several years has been PROSE, a program synthesis framework for mass-market development of by-example technologies. For details on other projects, please see my CV and the list of publications.

I completed my Ph.D. in the Paul G. Allen School of Computer Science & Engineering at the University of Washington. My advisors were Sumit Gulwani and Zoran Popović. Before joining UW, I received my B.S. in System Analysis with honors from the National Technical University of Ukraine “Kyiv Polytechnic Institute” in 2012.

We are hiring! If you are interested in a Research Scientist position in program synthesis, let me know!
