Biographical details

Tom Roberts has interests in molecular aspects of plant science as well as the functionality of food components. He heads a research group working on several projects on a range of cereals including rice, barley, sorghum and wheat, and has research collaborations with dynamic Australian agricultural companies. During his career, Roberts has taught a broad range of undergraduate units in the molecular biosciences and is currently the Plant Science Education Representative for the Australian Society of Plant Scientists (ASPS).

After studying at James Ruse Agricultural High School, Roberts completed a BScAgr at the University of Sydney in 1988, majoring in Agricultural Chemistry. He received an Alexander Hugh Thurburn PhD scholarship and graduated in 1995 with a PhD thesis entitled ‘Glyoxylate aminotransferases and ureide catabolism in the developing fruits of legumes’ under the supervision of Edith Lees and Les Copeland.

Roberts worked as a Postdoc at Lund University, Sweden (1994-5) on the properties and functions of the NAD(P)H dehydrogenases in plant mitochondria. Back in Sydney he developed novel methods for the purification of pharmaceutical-grade lactose from cheese whey at the University of Western Sydney/CSIRO (1995-6). He returned to Scandinavia and worked as a technical editor at Lund University and at the Royal Agricultural and Veterinary University in Denmark, as well as a Research Scientist at Novartis Seeds in Sweden. He then completed a 3-year Research Fellowship (1997-2000) at the Risø National Laboratory and the Technical University of Denmark on the properties and functions of the serpin family of proteins in barley and wheat.

In 2000, Roberts began work as a Research Fellow in the Macquarie University Centre for Analytical Biotechnology and conducted research on the mechanism, structure and regulation of magnesium chelatase, a key enzyme in chlorophyll biosynthesis. In 2004 he accepted an ongoing lectureship at Macquarie University and was a Key Researcher in the Grain Foods Cooperative Research Centre (2004-9). Roberts took up a Senior Lectureship at the University of Sydney in 2012.

Research interests

Tom Roberts’ research concerns a variety of plant proteins and small molecules, their properties, roles in the plant, and functionality in foods. He has had a long-term interest in the evolution, inhibitory properties and functions of the serpin family of proteins in plants. He also works on peanut allergens; the chemistry and biochemistry of sorghum grain, particularly phenolic compounds and the effects of malting; the diversity and evolution of pigments in wheat rust; and the properties of Australian native rice species, including canopy structure, seed quality and salt-tolerance mechanisms.

Roberts’ research involves a broad range of techniques in plant physiology, cell biology, molecular biology, protein biochemistry and food chemistry.

Please contact Tom Roberts if you are interested in pursuing a PhD in one of the above topics.

Teaching and supervision

In 2016 Tom Roberts is joint coordinator of AGEN2001 Plant Function, and coordinator of AGCH3025 Chemistry & Biochemistry of Foods. He is contributing to the teaching of AGEN3004 Food Processing & Value Adding and to AGEN1006 Biological Chemistry.

Roberts is Research Supervisor for following PhD students Ali Khoddami (sorghum grain chemistry and biochemistry), Sergio Nicolas Daneri-Castro (aleurone cell death in barley germination), Erpei (Amy) Wang (diversity and evolution of rust pigments), Yoav Yichie (salt-tolerance mechanisms of Australian wild rices), and for the MPhil student Sayedur Rahman (physiology and grain quality of Australian wild rices).

Roberts’ PhD graduates: Rodrigo Siqueira Reis (double-stranded RNA binding proteins in plant gene silencing); Nicole Walczyk (effects of plant environment on peanut allergenicity); Renan Ersoy (expression of serpin genes in Arabidopsis and rice); and Joon-Woo Ahn (functional characterization of serpins in plants and green algae).
