Izak Oltman
My name is Izak Oltman. I am an NSF Graduate Research Fellow and a fifth-year math graduate student at UC Berkeley studying analysis. My advisor is Maciej Zworski.
Here is my cv.
This semester I am co-organizing the Harmonic Analysis and Differential Equations Seminar (HADES) with Ely Sandine, Ovidiu Avadanei, and Ben Pineau.
During the Spring of 2023, I co-organized HADES with Zhongkai Tao.
During the Fall of 2022, I organized a seminar on semi-classical analysis.

Other math writing
- Qualifying Exam Study Guide. This is a document I wrote to study for my qualifying exam that is riddled with typos and incomplete sections. It may be a helpful reference to others studying the subjects.
- REU report on microfluidic device design completed at the University of California, Los Angeles (2018).
Misc
I passed my qualifying exam on April 12th, 2021. Here is my syllabus.
From 2020 - 2022 I was an officer of the Mathematics Graduate Student Association (MGSA) at UC Berkeley.
I also enjoy running, hiking, climbing, and playing violin.
I have crocheted a number of mathematical surfaces which can be seen here.
I believe I hold the current course record for 1600m at the Hearst Mining Circle: 5:33 , 5:23, 5:00.5.
