CAREER SUMMARY
- Mr. Indika Shameera Amarasinghe is currently working as a Full-time Lecturer in Mathematics at the Department of Mathematics and Statistics (DMS) at SLIIT UNI, Malabe. He has more than 10 years of lecturing and academic experience in Mathematics in Sri Lankan state and non-state Universities. He has maintained a very good track record on academic publications in Mathematics (Pure Mathematics) by publishing many refereed publications in reputed International Mathematics Journals with good citations, even way before (since the period of first-year undergrad as the single author) obtaining his Bachelor’s Degree. He has also academically edited and proofread over 10 Pure Mathematics course materials, including some of his own content, issued by The Open University of Sri Lanka (OUSL) in line with SLQF guidelines. (i.e. PEU3300-Mathematical Logic and Mathematical Proofs, PEU3301-Foundations of Mathematics, PEU4300-Real Analysis I, PEU4301-Real Analysis II, etc)
