Biography
Dr. Asmala bin Ahmad received B.App.Sc. (Hons.) in Geophysics from Universiti Sains Malaysia (USM) in 1996, MSc. in Land Surveying (Remote Sensing) from Universiti Teknologi Malaysia (UTM) in 2001 and PhD in Applied Mathematics (Remote Sensing) from University of Sheffield, United Kingdom in 2012. The title of his PhD thesis is "Atmospheric Effects on Land Classification Using Satellites and Their Correction". He is currently an Associate Professor at the Department of Intelligent Computing and Analytics, Faculty of Information and Communication Technology (FTMK), Universiti Teknikal Malaysia, Melaka (UTeM). He is a member of Optimisation, Modelling, Analysis, Simulation and Scheduling (OptiMAS) research group, Centre for Advanced Computing Technology (C-ACT), UTeM. He is also a professional member of the Institution of Geospatial and Remote Sensing Malaysia (IGRSM).

His research interest includes remote sensing, image processing, artificial intelligence and applied mathematics. Before joining UTeM in June 2003, he was a research officer at the Malaysian Remote Sensing Agency (ARSM), Ministry of Science, Technology and Innovation (MOSTI) from 1999 until May 2003. At ARSM, he involved in a number of international and national projects such as Establishment of a GIS Database for Sumatra, Borneo and Peninsular Malaysia (ASEAN-UNEP), AIRSAR PACRIM Programme (MACRES-NASA), and the development of Microwave Remote Sensing Applications using space-ground utilities (MACRES-MMU). He has authored and co-authored more than 70 research papers and articles in national and international publications. He was also the leader and member for a number of research grants from UTeM, Ministry of Higher Education (MOHE) and Universiti Teknologi Petronas (UTP).
