BIOGRAPHY

Dr. Nazhatulshima Ahmad is a Senior Lecturer in the Department of Physics, Faculty of Science, University of Malaya, where she has been a member of the academic staff since 1999. She received her BSc in Physics (1998), MSc in Astronomy (2003), and PhD in Physics (2013) from the University of Malaya. Her doctoral research, entitled “The Characteristics of Be Stars in the Delta Scorpii System,” focused on the variability and physical properties of emission-line stars.

Dr. Nazhatulshima has played an important role in the development of observational astronomy at the University of Malaya, contributing to the establishment and growth of research activities in optical astronomy. She currently leads the Optical Astronomy Research Laboratory, where she coordinates observational programs, research projects, and collaborative activities related to stellar astrophysics and small-body studies.

Her research focuses on emission-line stars, particularly Be stars and short-period eclipsing binaries, with an emphasis on photometric and spectroscopic variability. In addition, she is actively involved in the observation and monitoring of asteroids and Near-Earth Objects (NEOs), including astrometric observations and orbital analysis to support planetary defence initiatives.

Dr. Nazhatulshima also conducts studies on light pollution and its impact on astronomical observations, with the aim of improving observational site quality and protecting dark skies for scientific research.

Beyond her astrophysical research, she collaborates with the Department of Islamic Development Malaysia (JAKIM) on astronomical applications relevant to the Muslim community. These include observational and computational studies on crescent moon visibility for the Islamic months of Ramadan, Shawwal, and Zulhijjah, as well as investigations into the astronomical determination of Isha’ and Fajr prayer times.

Through her work, Dr. Nazhatulshima continues to contribute to the advancement of observational astronomy in Malaysia while fostering collaborations that integrate scientific research with societal and cultural applications.
