Computer Science is composed of many different areas of research, such as Algorithms, Programming Languages, and Cryptography. Each of these areas has its own problems of interest, publications of record, idioms of communication, and styles of thought.Segfault is a podcast series that serves as a map of the field, with each episode featuring discussions about the core motivations, ideas and methods of one particular area, with a mix of academics ranging from first year graduate students to long tenured professors.I’m your host, Soham Sankaran, the founder of Pashi, a start-up building software for manufacturing. I'm on leave from the PhD program in Computer Science at Cornell, where I work on distributed systems and robotics, and I started Segfault to be the guide to CS research that I desperately wanted when I was just starting out in the field.
