Daniel O.


Dan’s first science experiment involved a blow dryer, a basin of water, and a heat lamp. He was eight years old and thought he could build a miniature storm cloud after learning in school about how the water cycle worked. Though the experiment was not exactly a success, Dan has been trying to understand how things work ever since. He attended the University of Chicago as an undergraduate where he received a B.S. in mathematics and B.A. in physics, both with honors. He then went on to New York University where he did his PhD in theoretical particle physics and cosmology, graduating in 2021 with his dissertation on the topic of modifications of Einstein's theory of general relativity- our current best theory of gravity. Currently, Dan works as a machine learning scientist in the area of computer vision, using algorithms called deep neural networks to help computers learn how to understand visual data like how to detect people and objects in pictures and videos.

Dan has been teaching and tutoring math and physics for the past 8 years and doesn’t plan to stop anytime soon. While he has been a teaching assistant in courses such as calculus, real analysis, electromagnetism, and relativity, he has experience tutoring students of all ages and levels from elementary school through college in subjects ranging from adding and subtracting fractions to solving Schrodinger’s equation. He was awarded the UChicago College Core Tutor Award for the 2014-2015 academic year for his services as a general physics tutor.

Outside of academic pursuits, Dan enjoys a good pick-up basketball game and hikes in the woods and mountains.

    "I have engaged over 10 tutors in the past twenty years to help me self-study topology, differential geometry, general relativity and QFT for the past twenty years. All of them were very talented, but Dan is without question the "supremum of the set"; in that he is the most knowledgeable and delightful. No question in his broad purview remains unanswered. He furthermore allows the student to follow a non-linear learning path, if so desired, and sample any topic in which the student is interested at any time. He always avails himself to unscheduled questions that come up as you study. However, the most wonderful of all of his many attributes is the fact that Dan conveys to the student his love, enthusiasm and wonder for the spectacular physical universe around us. In short, Dan is the best. Look no further."
