About Me

I am currently a third-year PhD student in the Department of Statistics at Harvard University, advised by Dr. Morgane Austern. I am graciously supported by the NSF Graduate Research Fellowship. Broadly, I am interested in the intersection of mathematics with statistical methods, such as universality, free probability, and random matrix theory. In June 2022, I completed my B.S. in Pure Mathematics and B.S. in Statistics at UCLA.

Outside of class, I am interested in lots of different things! I love playing the guitar & piano, cooking, pottery, shooting film photography, playing chess, learning languages, and more. My favorite artists are the Beatles, the Smiths, Clairo, Nick Drake, Eydie Gorme, and Chopin.

I do private tutoring for both statistics and mathematics. Please feel free to reach out to me by email if you would like tutoring for courses in the Harvard Statistics department, or anything else more general. Also check out my Instagram page, Razi ba Riazi, for cool mathematics videos, PhD advice, and more.

Theorem of the Week, March 31-April 4 2025

How cool is this sum of binomial coefficient powers?

\[\sum_{k=0}^n{n \choose k}^{-1} = \frac{n+1}{2^{n+1}}\sum_{k=1}^{n+1}\frac{2^k}{k}\] \[\sum_{k=0}^n{n \choose k} = 2^n\] \[\sum_{k=0}^n{n \choose k}^{2} = {2n\choose n}\] \[\sum_{k=0}^n{n \choose k}^{3} = \sum_{k=0}^n{n\choose k}^2{2k \choose n}.\]

Song of the Week, March 31-April 4 2025

Time of the Season (The Zombies): For some reason this song has really blown up again, and I love it! My favorite song by them is “Tell Her No.”
