Reference excerpt

Priyanga Ranasinghe (born November 20, 1982) is a physician, clinical pharmacologist, academic, and researcher. He is a professor in Pharmacology at the Faculty of Medicine, University of Colombo. Ranasinghe's research focuses on non-communicable diseases such as hypertension and diabetes, as well as herbal medicines, and pharmacogenomics. He is a fellow of the Royal College of Physicians of Edinburgh.

Education Ranasinghe completed his M.B.B.S. from the University of Colombo in 2008. Later, he received an M.D. (Medicine) and a Ph.D. in Clinical Pharmacology from the University of Colombo in 2018.

Career Ranasinghe joined the University of Colombo as a research associate in 2008, a position he held until 2009. From 2012 to 2018, he worked as a lecturer in the Department of Pharmacology at the University of Colombo. Following this, he was then appointed as a senior lecturer in the same department from 2018 to 2019. Since 2019, he has been a professor at the University of Colombo. During this time, he has been the head of the Department of Pharmacology and chairperson of the Ethics Review Committee at the Faculty of Medicine. From 2021 to 2023, Ranasinghe served a specialty registrar in Clinical Pharmacology and Therapeutics, Acute and General Medicine at the Royal Infirmary of Edinburgh. In 2022, he became a board certified specialist in Clinical Pharmacology and Therapeutics in Sri Lanka. He was the secretary of the Sri Lanka Association of Clinical Pharmacology and Therapeutics (SLACPT) from 2023 to 2024, where he continues as a council member for the term 2025 to 2026. He is also an Ambassador of the British Pharmacological Society (BPS).

Research Ranasinghe's research has focused on the risk factors of diabetes, hypertension, and cardiovascular disease, with attention to metabolic syndrome, which he identified as a rapidly growing public health concern in Asia. His studies and clinical trials have demonstrated that zinc supplementation significantly improves metabolic health by reducing glycemic indices, such as postprandial glucose, fasting blood sugar, and HbA1c, decreasing insulin resistance while increasing β-cell function, and lowering the progression from prediabetes to diabetes. He further reported beneficial effects of zinc on lipid profiles in both healthy and non-healthy individuals. In addition, Ranasinghe explored the pharmacological potential of Cinnamomum verum (Ceylon Cinnamon), demonstrating its safety in healthy adults and showing that its daily doses were well tolerated while providing metabolic benefits. His experimental studies further showed that Cinnamomum zeylanicum extracts lowered blood glucose in diabetic models, with stem bark fractions also effective in managing type 2 diabetes mellitus. Beyond metabolic research, he examined irrational drug use, demonstrating the need for corrective measures to promote rational prescribing, and emphasized that producing data on frequently prescribed medicines throughout the health system supports better health management and enhances outcome-based medical education. Ranasinghe has also conducted research on improving hypertension prevention, detection, and noted that new therapies targeting biological mechanisms could enhance long-term treatment outcomes. His studies also examined CYP2C19 and CES1 gene variants influencing clopidogrel metabolism in Sri Lankan populations, highlighting the impact of genetic variation on antiplatelet efficacy. His work also reflects broader pharmacogenomic principles, emphasizing how genetic variability contributes to differences in the efficacy and safety of therapeutic agents, including anti-cancer drugs. He has reported that certain minor allele frequencies may elevate the risk of statin-induced myotoxicity, supporting his work on genotype-phenotype correlations in statin-treated Sri Lankan patients. He has been named in the Stanford/Elsevier World's Top 2% Scientists list in 2022, 2023, and 2024.

Worked examples

Example 1 — a first encounter with Priyanga Ranasinghe

Start with the simplest possible case. Write down what Priyanga Ranasinghe claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Priyanga Ranasinghe before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Priyanga Ranasinghe ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Priyanga Ranasinghe

In research: Priyanga Ranasinghe appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Priyanga Ranasinghe in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Priyanga Ranasinghe is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1982 births, 21st-century medical doctors, Academic staff of the University of Colombo, so understanding it makes those chapters shorter.
In everyday life: Look for Priyanga Ranasinghe outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
