The Australian Academy of Science has elected three University of Sydney academics as Fellows, recognising outstanding careers and continuing excellence in scientific research.

Professor Maria Byrne, a marine biologist from the School of Life and Environmental Science, Professor Alex Molev, a pure mathematician from the School of Mathematics and Statistics, and Professor Catherine Stampfl, a condensed matter physicist from the School of Physics, join 540 eminent scientists as Fellows of Australia鈥檚 leading scientific society.

The Dean of Science, , said: "It鈥檚 a great honour to welcome new Fellows to the Faculty, which shows the breadth, depth and quality of our research."

Australian Academy of Science President, , congratulated the new Fellows for making significant and lasting impacts in their scientific disciplines.

"These scientists were elected by their Academy peers following a rigorous evaluation process. What stands out among the new Fellows elected this year is the collective impact of their science on an international scale," Professor Shine said.

Marine biologist is leading international expert on echinoderms, which are some of the most beautiful and interesting animals in the sea. They include feather stars, sea stars, brittle stars, sea urchins and sea cucumbers.

More than 1000 species live in Australian waters and play an important ecological role. Several species of sea urchins and sea cucumbers form the basis of important fisheries. Many are still to be found and studied.

Professor Byrne helped write the definitive guide on听,听which听provides comprehensive information on the identification, biology, evolution, ecology and management of these animals for the first time.

In December last year on the Great Barrier Reef she witnessed the head of a crown of thorns sea star larvae pop off which proved for the first time it听can reproduce by cloning.

This discovery is described in the paper, 鈥淟arval cloning in the crown-of-thorns sea star, a keystone coral predator鈥�, published in the journal听.

Professor Byrne and her team hope they may be able to limit the outbreaks of these coral-munching echinoderms by applying this new knowledge.

Maria Byrne鈥檚 research on Evolution of Development is globally recognised for key discoveries on how animal body plans evolve and has greatly enriched our understanding of Australia鈥檚 marine biodiversity. She uniquely uses life-history diversity in endemic species to discover how developmental change drives speciation. She has advanced knowledge on the important marine phylum Echinodermata, culminating in a definitive textbook and monograph for Australia. She is also a recognised leader in Global Change Biology, documenting the impacts of ocean acidification and warming on marine invertebrate life stages revealing the adaptability of marine species that is key to understanding their future prospects.

Alexander Molev is a听pure mathematician听who has made substantial research contributions to algebra, representation theory, algebraic combinatorics and mathematical physics. He is a world-leading expert on 鈥樷��, a particular class of quantum groups, that he has used to solve longstanding open problems. Professor Molev鈥檚 book听听is widely viewed as the definitive monograph in the field. In 2001, Molev was awarded the prestigious AustMS Medal of the Australian Mathematical Society for his work in representation theory.

Catherine Stampfl is a theoretical condensed matter听physicist听with an outstanding international reputation for her investigations into the atomic and electronic structure of solids, their surfaces, interfaces and nanostructures. She uses accurate first-principles calculations, in conjunction with high-performance computing, to gain fundamental understanding of the behaviour of matter and to predict new and improved materials for technological applications. Professor Stampfl has made paradigm-shifting investigations in the area of theoretical surface science and sustained contributions in materials for nanoelectronic devices. Her research bridges the fields of physics, chemistry, engineering and materials science.
