About the Program

Prepare to be a tech leader with a PhD in Computing and Information Science from Case Western Reserve University. Since launching one of the first accredited computer science programs in the United States, we haven’t stopped innovating in and out of the classroom. Our program offers coursework on algorithms, data science, AI and more, along with computing facilities to test your knowledge, like the Virtual Worlds lab. The education and practical experience you receive at Case Western Reserve will prepare you to advance the fields of computer science and information technology—which are the lifeblood of many industries.

What to Expect

We’re one of the top-ranked engineering schools in the country because of our internationally renowned faculty and motivated students. We keep classes small so you can get the most out of your program. As you progress, you’ll choose coursework based on your interests, specializing in areas such as security and privacy, data mining, or algorithms and theory—and you’ll use what you’ve learned as a basis for your research. By the end of the program, you’ll have attended three semesters of a colloquium presentation which will expand your knowledge of the field.

My experience at CWRU was rewarding as I not only expanded my knowledge but I also found my role model in the computer science department. I had the best advisor, the best mentor and great teachers. My advisor always believed in me and treated me as a valued scientist, not as ‘just a grad student.'
