Mutiara (Tia) Sondjaja


I am a Clinical Assistant Professor in the Department of Mathematics at Courant Institute of Mathematical Sciences, NYU. I completed my Ph.D. at Cornell University, where I was advised by James Renegar. I obtained my undergraduate degree in mathematics in 2008 from Harvey Mudd College.

At NYU, my primary interests and responsibilities are undergraduate teaching. I maintain active research interests in continuous optimization and in mathematical problems motivated by questions in the social sciences.

Fall 2018

In Fall 2018, I am teaching Calculus 2 and a new quantitative reasoning course, From Data To Discovery.

From Data To Discovery is not a statistics course, although we will learn a bit of statistics. It is not a programming course, although we will learn some basic aspects of programming. In the course, we will explore a variety of datasets and try to glean meaningful insights from them. Along the way, we will learn to think critically about data, including how to use computing tools to help us visualize and summarize data and how to interpret results of data analyses. Throughout the course, we will also examine issues such as data privacy and ethics.

The course has no prerequisite beyond high school mathematics. If you are a student who is not sure whether this class is for you, you are encouraged to email me.
