OwnerAparna Pai, Owner / Center Director

Aparna has a BS in Engineering from India and an M.S. in Computer Science from Illinois Institute of Technology. Prior to getting involved in Mathnasium, she worked in information technology industry for several years in varied roles and responsibilities. As a child she really enjoyed and looked forward to learning math. Her interest in teaching math began as she was trying to find ways to make learning math a fun activity for her older son and found that there were very few such resources available for parents. Her own experience had taught her that kids excel in math when it is taught in a way that is fun and intellectually challenging. Her quest to do so brought her in touch with Mathnasium. Aparna is very enthusiastic about Mathnasium curriculum since it is taught in the way that makes sense to kids. The sharp focus on “why” rather than the plain “how” to do a math problem is the essential Mathnasium differentiator. Her goal is to use math make every child a better thinker and problem solver. Students that need remedial focus and enrichment are welcomed and challenged.  She has been doing this for over 7 years and loves every moment of working with students and empowering them. She has two sons, Nachi , a UIUC Industrial Engineering graduate currently working for Pepsi and Neel, a 17 year old junior at Neuqua.

Melanie Woods, Assisstant Center Director

Melanie has a strong STEM background with degrees in computer science and physics along with 10 years of software development experience. This may seem an unusual outcome for someone who struggled with math in elementary school. That changed with the encouragement of a 7th grade math teacher who made class fun. Math finally began to make sense! This experience has motivated her to help others develop a good attitude toward math and probem solving in general. She believes that with patience and positive feedback anyone can gain a better understanding of math. Melanie has two college-aged daughters urrently pursuing degrees in science and engineering.

Ryan Macwan, Instructor

I am currently doing my undergrad at DePaul University in Computer Science. I've loved logic and math ever since I was a kid, because it challenged me intellectually not physically. Being homeschooled allowed me to learn math at an accelerated pace. I have had a passion for kids ever since I was a teen, and I know how to be patient, fun, and stern with them. When I'm not working as a math tutor or studying I enjoy playing table tennis and board games, reading books, and contemplating philosophical ideas.

Noah Woods, Instructor

Noah Wood is a recent graduate of the University of Illinois. Even since he was young he always enjoyed math. His passion for numbers is one of the reasons he chose to get his degree in chemical engineering. Getting the degree made him appreciate math for its ability to predict real world phenomena. Recently he has picked up fly fishing as a hobby. He has found the sport to be both challenging and rewarding, as there is something quite satisfying about fooling a fish to bite a fly.

Favorite Number: 16

Favorite Math Joke: What do you call a mathematician who goes on a lot of dates, but who doesn't like to talk about it?  A discrete data!

I love Mathnasium because: Even I can still learn from the Mathnasium curriculum! I learned about the cake method for finding the greatest common factor and least common multiple. Mathnasium presents material in different ways than the school system does and I think it's beneficial to see more than one approach to a problem.

Nathan Knauf, Instructor

Hi, my name is Nate, and I am a recent graduate from the University of Illinois with a degree in physics. I have had a passion for learning and sharing math for as long as I can remember, from drawing the number “8” over and over with my mother as young boy to guiding my roommates through the perils of calculus 3. What amazes me about math is that we can know more about a situation than when we started by drawing a bunch of symbols on paper. I am very enthused by mathematics and enjoy passing that energy along. I hope that my excitement and patience can help students achieve the satisfaction of feeling “I get it!”

Favorite Number: 73

Favorite Math Joke:  The problem with math puns is that calculus jokes are all derivative, trigonometry jokes are too graphic, algebra jokes are usually formulaic, and arithmetic jokes are pretty basic. But I guess the occasional statistics joke is an outlier.


In five years, I will be:  Using math to find actionable insights in an analytics role, i.e. turning math into money!

I love Mathnasium because: We work to find ways for students to think about math, not just do it. I love challenging students to be mathematicians and not calculators!

Fun Fact: I'm a huge Harry Potter fan and I have read all the books at least 4 times.
