Steven Gubkin

PhD Mathematics, Ohio State University, 2015
- L² Mergelyan Theorems in Several Complex Variables
- This thesis was in the broad area of “holomorphic approximation theory”. I am finding that this work is preparing me well to think deeply about machine learning, which also deals with approximations in function spaces.
BSc Mathematics, Case Western Reserve University, 2015
Erdős institute data science bootcamp, May 2023
- Learned how to use numpy, pandas, and scikit-learn libraries. Learned fundamentals of data science including data collection, exploration, and cleaning, regression and classification techniques, dimension reduction, clustering, and the basics of neural networks.
- Completed a project to translate American Sign Language to text.
The website you are currently browsing contains:
- An exposition of the creation of a MathOverflow tag recommendation system.
- A few notes on the mathematical underpinnings of machine learning.

Taught a wide variety of courses including Calculus, Linear Algebra, Multivariate Calculus, Complex Analysis, Abstract Algebra, Discrete Mathematics, and Number Theory.
Served on committees including Undergraduate Program Committee (helping to design and maintain our major/minor requirements, proposing new courses, etc) and several hiring committees.
Served as course coordinator for our Mathematics for Future Elementary Educators courses.
- I was committee chair and primary author of the Ohio36 learning outcomes for these courses (TMM021 and TMM022), which are now the standards used to permit transferability of these courses in the state of Ohio.
Authored an intro proof textbook which takes a natural deduction approach.

As a graduate student I assisted with the creation of one interactive online textbook and two MOOCs which were run by Ohio State through Coursera.
- This open source online interactive Calculus textbook is still in use by Ohio State.
- Mooculus was a fairly standard Calc 1 experience. I wrote almost all of the interactive exercises for this course using Khan Academy’s exercise framework.
- M2O2C2 was an interactive tensor algebra based multivariable calculus course. I authored most of the “textbook” content for this course. You can read my description of the course content here if you are interested.
