Yes, you can pursue a Ph.D. in Computer Science (CS) with your M.Sc. in Software Engineering. Most universities require a master's degree in a relevant field and may also ask you to clear an entrance exam (like UGC NET, GATE, or university-specific tests). Ensure you meet the eligibility criteria, such as research experience or a strong academic record, and prepare a research proposal. Contact universities or check their Ph.D. admission notifications for further details.
