Teaching Assistant

CS 014 - Introduction to Data Structures and Algorithms (Fall 2017, Summer 2018): CS 014 introduces the students to the fundamental data structures and algorithmic analysis techniques such as lists, stacks, queues, search trees, sorting algorithms, hash tables, and graphs.

CS 141 - Intermediate Data Structures and Algorithms (Winter 2018, Spring 2018): CS 141 provides the basic background for a computer scientist in the area of data structures and algorithms. During this course, students will learn problem solving skills, how to compare them, and how to apply them in real problems.

CS 218 - Design and Analysis of Algorithms (Fall 2018): Study of efficient data structures and algorithms for solving problems from a variety of areas such as sorting, searching, selection, linear algebra, graph theory, and computational geometry. Worst-case and average-case analysis using recurrence relations, generating functions, upper and lower bounds, and other methods.

CS 167 - Introduction to Big Data (Spring 2020): CS 167 covers the data management and systems aspects of big data platforms such as Hadoop, Spark, and AsterixDB. In this course, you will learn how the data is stored in a distributed file system and how the queries run in parallel.
