Sukh Dev
Indian organic chemist Professor Sukh Dev, a TWAS Fellow since 1991, passed away on 16 October 2024.
A native of Punjab, he earned his master's degree from the Dayanand Anglo Vedic College, Lahore, and his PhD from the Indian Institute of Science (IISC), Bangalore.
Dev focused his scientific interests on a class of naturally occurring organic compounds called terpenoid, the properties of which he investigated. This research, in turn, led him to discover new structures in chemicals called sesqui- and diterpenoids.
While studying Indian medicinal plants, he discovered a substance called guggulsterone, in the resin of the guggul plant (Commiphora mukul), which seemed a promising agent to lower cholesterol.
He was a prolific scientist, scholar and writer, with more than 290 research papers published in his name, 10 books and 55 patents. His most famous book, published in 2006, is Prime Ayurvedic Plant Drugs, which explores the ancient and modern traditions of Ayurvedic medicine.
Among the recognitions that he received are: the Shanti Swarup Bhatnagar Prize (1964), the most prestigious Indian award in the science and technology categories; TWAS Award in chemistry (1988); and the Srinivasan Ramanujan Birth Centenary Award of the Indian Science Congress Association (1992).

Anita Dolly Panek
Brazilian biochemist Anita Dolly Panek, elected to TWAS in 1989, passed away on 27 March 2024. Panek was a full professor in the department of biochemistry at the Federal University of Rio de Janeiro (UFRJ), Brazil, since 1976. A native of Poland, she moved to Brazil because of World War II, and, in 1962, she obtained her PhD from UFRJ.
Her research focused on the metabolism of a sugar called trehalose, which has a pivotal role in the metabolism of yeast Saccharomyces cerevisiae, used in winemaking, baking, and brewing. She clarified the function of the sugar trehalose in yeast, proving that it is a source of energy during cell division. In addition, she showed that trehalose produced internally by yeast cells protects them against damage from stressors such as freezing, dehydration, heat, and germination.
She obtained three patents for processes regarding the attainment, use, and purification of trehalose. Since 1961, she was a research scientist at the National Research Council and was also a member of the Brazilian Academy of Sciences, Rio de Janeiro, and of the Latin American Academy of Sciences, Caracas, Venezuela. In 1996, she received the Commander of the Order of National Scientific Merit.

Hoosen 'Jerry' Coovadia
Hoosen 'Jerry' Coovadia, an emeritus professor of paediatrics and child health with the Nelson Mandela School of Medicine, University of KwaZulu-Natal, in Durban, South Africa, passed away on 4 October 2023. Elected to TWAS in 2005, he spent his career caring for the poorest in South Africa. His efforts were focused on the understanding of the immunodeficiency of malnutrition, infectious diseases, measles and kidney disease in African children.
He specialised in paediatrics at the University of Natal and became a Fellow of the College of Paediatricians of the Colleges of Medicine of South Africa, in 1971. In 1974, he earned a master’s degree in immunology from the University of Birmingham, UK.
He carried out ground-breaking research about the transmission of HIV from mother to child. His results proved that the risk of HIV mother-to-child infection through breastfeeding is greatly reduced if the baby receives antiretroviral drugs, or the mother exclusively breastfeeds. Coovadia's achievements shaped international policies about the prevention and treatment of HIV/AIDS, changing the stigma whereby women with HIV should not breastfeed their babies.
In 1984, he released the first edition of his textbook, Coovadia’s Paediatrics & Child Health: A manual for health professionals in developing countries, which marked the path for generations of paediatricians. In 2021, the seventh edition of the book was released.
In 2000, he served as co-chair of AIDS 2000, the 13th International AIDS Conference held in Durban, and played a pivotal role in the preparation of the Durban Declaration. Over 5,000 among scientists and leading academics signed the document as a response to HIV/AIDS denialism. The declaration stated that "[t]he evidence that AIDS is caused by HIV-1 or HIV-2 is clear-cut, exhaustive and unambiguous, meeting the highest standards of science".
He was also the associate scientific director at CAPRISA, the Centre for the AIDS Programme Research in South Africa. The awards he received include the Order of the Star of South Africa (1999), the Nelson Mandela Award for Health and Human Rights (2000), and the AAAS Award for Scientific Freedom and Responsibility (2013).
