Dr. Rajesh Ranjan is an Assistant Professor in the
Department of Computer Science and Engineering
at South Asian University (SAU),
New Delhi. Before
joining SAU, he served
at The LNM Institute of Information Technology (LNMIIT), Jaipur, and has over
eight years of academic and research experience. He holds a Ph.D. in Computer
Science and Engineering from NIT Kurukshetra, an Integrated B.Tech–M.Tech
degree from ABV- IIITM Gwalior, and a Post Graduate Diploma in Big Data
Analytics from C-DAC Pune. His research explores areas such as unsupervised
learning, nature-inspired and metaheuristic optimization, data analytics, as
well as biometric systems, with a focus on developing scalable and
interpretable computational models that advance data-driven intelligence. He
has published several papers in reputed SCIE and Scopus-indexed journals,
contributed to projects in multimodal biometrics and multilingual speech
processing, and serves as a reviewer for multiple international peer-reviewed
journals.
