Hi, I'm Sina! For the last six years, I've taught university classes of 30-100 undergraduate students, including mathematics majors, and served as the lead instructor for Calculus I, II, and III. I hold a master's degree in Applied Mathematics and Statistics and am a PhD candidate in Industrial Engineering and Operations Research.

Hi, I'm Sina! For the last six years, I've taught university classes of 30-100 undergraduate students, including mathematics majors, and served as the lead instructor for Calculus I, II, and III. I hold a master's degree in Applied Mathematics and Statistics and am a PhD candidate in Industrial Engineering and Operations Research. Teaching has been a substantial part of my background, with university teaching roles from 2019 to 2025. I bring both a deep understanding of mathematics and the experience of explaining it to a classroom full of students with different questions and learning needs.

As a lead instructor, I took responsibility for the whole course: planning and delivering lessons, developing practice problems, and writing and grading exams. That experience gives me a valuable perspective on what instructors expect and how to help students show their reasoning clearly. I specialize in calculus, probability, statistics, and linear algebra, and I also help students strengthen their algebra, precalculus, and trigonometry foundations. My research and industry experience let me connect these subjects to real applications in data science, engineering, and machine learning.

You don't need to arrive at a lesson knowing exactly what to ask. Bring the problem that has you stuck, the exam you're worried about, or the topic that never quite clicked, and we'll start there. I'll break down the reasoning, explain why each step works, and give you room to try it yourself. If one explanation doesn't connect, I'll find another way to approach it using a graph, an example, or a simpler starting point. There is no embarrassment in revisiting the basics. My goal is for you to leave with more than a finished problem: I want you to understand the method and feel ready to tackle the next one. Send me a message with your course and goals, and let's get started!
