Dr. Yelena V. Kostova

Yelena Kostova is an Associate Professor in the Department of Computer Science at International University Canada, where she teaches and mentors students across the School of Engineering & Technology. Her academic work focuses on operating systems and computer architecture, examining how hardware and software components work together to manage computing resources, processes, and memory at a fundamental system level.

Throughout her academic career, Yelena Kostova has developed a teaching approach that connects low-level system concepts with their practical implications for software performance, helping students understand how operating systems manage processes, memory, and file systems in ways that affect every application running on a computer. She encourages students to develop a strong mental model of how computers actually work beneath the application layer.

In her courses, Yelena Kostova draws on operating systems case studies, computer architecture frameworks, and current research in systems-level computing to help students build foundational technical skills. Students explore topics such as process scheduling and management, memory management techniques, file system design, and the architectural principles underlying modern computer hardware and processor design.

As an Associate Professor within the Department of Computer Science, Yelena Kostova also contributes to curriculum planning that provides students with a strong systems-level understanding of computing fundamentals. She works closely with colleagues across the School of Engineering & Technology to ensure that coursework prepares students for further study in systems programming and computer engineering.

Yelena Kostova places particular emphasis on helping students understand the performance implications of operating system and architectural decisions, recognizing that systems-level knowledge helps developers write more efficient, well-optimized software. She designs coursework that connects low-level concepts to practical software performance considerations.

Recognizing that many of her students are working professionals studying online, Yelena Kostova structures her courses with accessible systems explanations, clear architectural diagrams, and consistent opportunities for applied practice. Her approach to online teaching emphasizes building a solid foundational understanding of computing systems that supports further technical specialization.

Students who study under Yelena Kostova often highlight her ability to make complex systems-level concepts clear and conceptually grounded. Her long-term goal as an educator is to help students develop the foundational technical knowledge needed to support careers in systems programming, computer engineering, and software performance optimization.
