H.A Nalani is, currently, a Senior Lecturer (Gr. II) at the Department of Remote Sensing and GIS, Faculty of Geomatics, Sabaragamuwa University of Sri Lanka. Mainly, she is teaching Photogrammetry for undergraduate and postgraduate students. Her research focuses on 3D modelling, laser scanning, close-rage Photogrammetric techniques, and UAV. She also has extensive experience working with RS&GIS applications and medical image analysis using photogrammetric techniques. She has been awarded the GFF+DAAD funds to pursue PhD in 2012, DAAD Scholarship in 2005 to complete M.Sc. and Mahapola Merit scholarship to complete BSc.
