Timothy Comar, Ph.D.
About Me

I am a retired college mathematics professor, and I have over 25 years of experience teaching and tutoring mathematics and statistics students at the high school and college levels. I tutor in any high school or college level mathematics or statistics course, including AP Calculus, AP Statistics, and SAT/ACT Mathematics preparation. I also tutor middle school students in high school mathematics courses. I am available over the summer to help students get ready for fall classes, including AP Calculus and AP Statistics. I am available for individual and group lessons. I can also design a course for individual study. I primarily tutor online. I have experience with Maple, MATLAB, Mathematica, GeoGebra, TI Graphing Calculators, Excel, Desmos, and NetLogo.

​

I reside in and am from Wilmette, IL, which is outside of Chicago.  I graduated from New Trier Township High School, where I fell in love with mathematics and first tutored other students.  I was on the Math Team.   I studied mathematics at Brown University, and completed my Ph.D. at The University of Michigan.  While my earlier work, was in low dimensional topology, I spent most of the research portion of my professional academic career pursing research in mathematical biology.  That is, I have significant experience in both pure mathematics and applied mathematics.  

​

My academic positions were at universities that were dedicated undergraduate education.  I have taught courses from the developmental level (corresponding to beginning high school courses) through advanced undergraduate courses.  I have taught numerous calculus courses at all levels. I have served as a Reader (grader) from AP Calculus exams. I also have mentored many undergraduate students in research projects in mathematical biology and knot theory.  Several of these students have won awards at national and regional meetings for their research work.
