Peer Math Tutoring


SUMO works with the Stanford math department to provide peer tutoring services for a number of introductory math classes, specifically MATH 19, 20, 21, 51, 52, 53, and 104. The peer tutors are available to answer any questions you have about the material and homework in these classes.

Peer tutoring hours are drop-in; just show up and our tutors will help you out. Feel free to come and work on your homework even if you don't have any specific questions. Many students work on their homework during tutoring, asking questions if they encounter difficulties.

Please note that this program is not aimed towards Math 60CM/DM students. For students in higher level math classes, the math department offers other resources.

Becoming a Tutor

If you are interested in becoming a peer math tutor, we hire new tutors at the start of Fall, Winter, and Spring Quarter of each academic year (if there are available positions). Tutors should be able to help students with either all three classes of the MATH 19/20/21 series and MATH 51, all three classes of the MATH 50s series, or MATH 104/113.

If there are any open positions for the quarter, the application for new tutors will be sent to the SUMO mailing list in the first week of classes. Please join the mailing list to be notified of these opportunities. If you have any further questions about tutoring or the application, please contact the coordinator, Jake Hofgard (whofgard at


Note: On Monday, May 29th, in-person tutoring will be held in the Huang Engineering Center basement study area due to the school holiday.

Tutoring starts week 2 and continues through the end of week 10, excluding university holidays. The schedule for each course is as follows:

Winter 2022 Sun Mon Tue Wed
Spring 2023 Sun (19/20/21/51) Mon (51/52/53/104) Tue (19/20/21/51) Wed (51/52/53/104)

Meet Our Tutors


Hi! I am a sophomore thinking of majoring in Computer Science. I am an international student from Thailand. My areas of interest in Math include probability and linear algebra. Outside of school, I enjoy playing table tennis and watching YouTube & K-series.


Hey! I am a senior majoring in math with a physics minor. I'm interested in AI safety, and I love physics/mathy stuff. Outside of academics, I enjoy meditating, rowing, and reading. I'm also exploring making educational youtube videos.


Hannah Prausnitz-Weinbaum is a junior studying mathematics and minoring in computer science. She loves helping other people get excited about math, and has been tutoring with SUMO for two years. When she's not in class, you can find Hannah knitting or singing a cappella.


Emma is a freshman planning to major in mathematics. She is also interested in applying CS and engineering to medical research, and currently works in a radiology lab studying tumor imaging. Outside of school, she enjoys rock climbing, baking, and watching sports.


Hello, my name is Jadon, and I am a sophomore studying Computer Science and Mathematics! Beyond the scope of academics, I love to play the piano and saxophone, and I enjoy sharing my passion for music with others through TikTok. I also love exploring geography, bullet journaling, walking, and being around cats (becase my allergies won't stop me). If you are looking for support in Math, I would be happy to connect with you.


Hello! My name is Rahma and I am a rising junior majoring in aero/astro (aerospace engineering) and double minoring in math and mechanical engineering. I absolutely love rockets. In math, I am really interested in calculus, specifically differential equations. Outside of math, I like to bike, play League of Legends and make song covers!


Yuzu Ido is an undergraduate at Stanford majoring in math and minoring in music. She has previously done research in algebraic geometry and graph theory. Outside of math, some of her interests are piano, CS, and eating good food.


Hi! I am a junior at Stanford majoring in computer science and minoring in math. I am also interested in the physical sciences, and I do research using machine learning in biological problems. Aside from school, I enjoy tennis, Brazilian music, and any type of handcrafting.


Manya is a sophomore studying Mathematics at Stanford. She enjoys learning more about measure theory, analysis, and statistical physics (and has somehow found herself taking more computer science classes than she ever intended). Her other interest include drawing, going on long walks and listening to a lot of music.

Mateo Attanasio

Mateo Attanasio is an undergraduate at Stanford studying mathematics. His current interests include algebraic number theory and topology. Outside of mathematics, interests include rock climbing and history.

Kaya Lakein

Hi there! I am a junior majoring in math and minoring in physics and TAPS. The areas of math that I am most interested in include algebraic number theory and most other algebraic things. I really enjoy teaching math to people of all backgrounds, and next to serving as the current SUMO tutoring coordinator, I am one of the math department's peer advisors, and I have graded Stanford math classes in the past. Aside from doing a lot of math, I like to dance, juggle, and go on long walks/hikes.


I'm a rising junior at Stanford studying physics, coterming in electrical engineering, and possibly minoring in creative writing. I'm involved in neuroscience research. For fun, I like to read fiction and memoirs that my friends recommend to me, listen to music, and (slowly) teach myself the acoustic guitar!


Jake is sophomore studying mathematics, with minors in computer science and history. His areas of interest in math include analysis, PDEs, probability theory, and mathematical physics. Outside of math, he enjoys anything that involves the outdoors, ranging from hiking to climbing to learning about water conservation.


Emily is a rising sophomore thinking about majoring in math. Some of the areas of math she's liked so far are number theory, probability, and algebra. In her free time she likes to swim and go on walks (during quarantine).


Jonathan is a Senior studying Mathematics and coterming in Computer Science. When he's not doing math, he's probably playing videogames, watching anime, or enjoying Ukrainian pop music.
