Optimising Resistant Starch Formation in Different Rice Varieties Under Various Processing Conditions

Primary Supervisor: Dr Boris Budiono
Co-Supervisors: Dr Nidhish Francis & Prof. Chris Blanchard
Location: Wagga Wagga
Keywords: functional foods, nutrition, food science, glycaemic index, diabetes
Research Group: Food as Medicine (FAM) Research Group

Synopsis:
Resistant starch (RS) is a form of starch that escapes digestion in the small intestine and reaches the colon, where it is fermented by gut microbiota into beneficial short-chain fatty acids such as butyrate. Increased RS intake is associated with improved glycaemic control, enhanced gut health, and potential protection against metabolic disorders. Rice is a staple food globally, including in Australia, but its high glycaemic index makes it less suitable for individuals with insulin resistance or type 2 diabetes. Evidence shows that cooking, cooling, and reheating rice can increase RS content, yet the optimal processing conditions for different rice varieties (e.g., white, brown, basmati, jasmine) remain poorly understood.

Project Aim:This study aims to investigate how different cooking, cooling, and reheating conditions affect the resistant starch content of various rice varieties. The findings could inform dietary strategies to reduce postprandial glycaemic responses and promote healthier carbohydrate choices.

Project Objectives:

Compare the RS content of freshly cooked, cooled, and cooled–reheated rice across multiple rice varieties.
Test different cooling durations (e.g., 4 h, overnight, 24 h) and reheating methods (microwave, stovetop) to identify the most effective strategies for RS enhancement.
Analyse the impact of these conditions on predicted glycaemic index using in vitro starch digestibility assays.

Methods Overview: Students will cook standardised portions of different rice varieties under controlled conditions, then subject them to various cooling and reheating treatments. RS content will be measured using AOAC-approved enzymatic assays. Optionally, samples may also undergo simulated in vitro digestion to assess glucose release rates. Results will be statistically analysed to determine which combinations of rice variety and processing condition yield the highest RS levels.

Expected Outcomes: This project will generate practical recommendations for preparing rice with improved nutritional profiles. The results could support future public health messaging or functional food development aimed at lowering dietary glycaemic load and improving metabolic health

Reconstructing infant palaeodemography using proteomic approaches

Primary Supervisor: Dr Melandri Vlok
Location: Orange
Keywords: biochemistry, demography, mortality, bioarchaeology, proteomics

Project availability: Semester 60, 2026, Semester 30, 2027

Synopsis:

Southeast Asian prehistoric archaeological human skeletal assemblages typically have excellent infant preservation. Biological sex is well known to factor into infant mortality with males presenting a higher risk of death in early life. Traditional osteological techniques, however, cannot determine the biological sex of archaeological infants as the methods rely on the development of secondary sex characteristics that emerge during puberty. This project applies the use of proteomic methods on determining sex from an early agricultural site in mainland Southeast Asia to assess whether this sex bias in mortality is represented in ancient cemetery populations.

The impact of sorghum phenolic compounds on risk factors of cardiovascular disease (CVD)

Primary Supervisor: Dr Boris Budiono & A/Prof Abishek Santhakumar
Location: Wagga Wagga
Keywords: cardiovascular disease, ischaemia reperfusion injury, mitochondrial dynamics, antioxidants, polyphenols
Research Group: Food as Medicine (FAM) Research Group

Cardiovascular disease (CVD) remains the leading cause of global mortality, largely driven by modifiable factors such as diet and exercise. Integrating bioactive-rich cereal grains into the diet is an emerging strategy to support cardiovascular health.

Sorghum (Sorghum bicolor L. Moench) is a climate-resilient staple in Africa and Asia that promotes food security. While its general health benefits are well documented, its role in reducing CVD risk—especially in protecting against ischemia-reperfusion injury, preserving cardiac mitochondrial function, and maintaining endothelial integrity—remains underexplored. Moreover, the influence of sorghum on neutrophil extracellular traps, key mediators in CVD progression, is not yet fully understood.

This study will fill these gaps by examining how sorghum-derived phenolic compounds impact CVD risk factors. Polyphenols will be extracted from whole grain sorghum and identified using UHPLC-Online ABTS and LC-MS/QTOF. In vitro models will assess their effects on molecular pathways linked to cardiovascular health using transcriptomic and proteomic techniques.

Findings will support the therapeutic potential of sorghum, expand its agricultural value, and drive innovation in heart-protective functional foods.

Design of Cholesterol Biosynthesis Inhibitors as Anticancer Agents

Primary Supervisor: Dr David Leaver
Co-supervisors: Dr Boris Budiono and Dr Ken Chinkwo
Location: Wagga Wagga
Keywords: cancer, cholesterol, enzymes
Study Availability: Available until December 2027
Research Group: Medical Sciences

Synopsis:
Much research over the last several decades has been focused on finding novel anticancer agents that inhibit cholesterol biosynthesis, however, there has been little to no success in this endeavor and the pharmaceutical industry is reluctant to pursue sterol biosynthesis inhibitor drug development. Over the last couple of years structural biology advances have enabled the crystal structures of post-squalene cholesterogenesis enzymes to be solved that can be used to design novel cholesterol biosynthesis inhibitors. This project will use a structure guided approach to discover new anticancer drugs that selectively inhibit cholesterol biosynthesis enzymes.

Crystal structures of enzymes in the post-squalene segment of cholesterogenesis A: Crystal structure of squalene monooxygenase bound with FAD (black) and “Cmpd 4” (blue), PDB 6C6N; B: Crystal structure of lanosterol synthase bound with lanosterol (black), PDB 1W6K; C: Crystal structure of Emopamil-Binding Protein bound with U18666A (red), PDB 6OHT; D: Crystal structure of sterol 14α-methyl demethylase bound with ketoconazole (red), PDB 3LD6.

Innovative nutraceutical strategies for the management of diabetes

Primary Supervisor: Dr. Nidhish Francis
Location: Wagga Wagga
Keywords: diabetes, polyphenols, cell culture, oxidative stress
Research Group: Food As Medicine (FAM) research group

Synopsis: This research project focuses on investigating plant-derived bioactive compounds, particularly polyphenols, as potential therapeutic agents for diabetes management. Diabetes, a chronic metabolic disorder characterised by impaired glucose metabolism and insulin resistance, affects millions worldwide. Current pharmacological treatments primarily manage symptoms but fail to address underlying mechanisms or prevent disease progression. This project aims to explore the potential of plant-derived polyphenols to regulate key pathways involved in diabetes development and progression.

Polyphenols, naturally occurring antioxidants found in plant-based foods, have shown promise in mitigating oxidative stress, inflammation, and insulin resistance—key contributors to diabetes pathology. This study will utilise advanced in vitro cell culture models to evaluate the effects of polyphenols on glucose uptake, insulin signalling, and oxidative stress markers. Molecular techniques such as RT-PCR and Western blot analysis will be employed to investigate the modulation of genes and proteins involved in glucose metabolism and inflammatory pathways. The findings aim to contribute to the development of natural, plant-based strategies for diabetes management, offering a complementary approach to conventional therapies. This project is ideal for candidates passionate about medical science, clinical nutrition, and exploring innovative solutions for diabetes care.
