Biography & Research Interests
Dr Richard Muhlack has a PhD in Chemical Engineering and 16+ years of wine sector experience in various industry and research roles across process analysis and simulation, cleaner production and energy efficiency, renewable energy technology, waste treatment and environmental management. In 2007 his research was the subject of an Econsearch report commissioned by GWRDC "Cost Benefit Analysis of a GWRDC Hero Project". In 2008 Dr Muhlack was awarded a DAFF Australian Agricultural Industries Young Innovators and Scientists Award (GWRDC Award).
In January 2014 Dr Muhlack transitioned from industry-based R&D (with the Hardy Wine Company across 1999-2008 and then AWRI from 2008-2014) to the University of Adelaide and now holds an academic position within the School of Agriculture Food and Wine, where he is working to pursue research and technical development projects in the following areas:
- Kinetic modelling of fermentation, extraction, adsorption processes during food and wine production
- Industrial Process Simulation and Optimisation
- Process efficiency and techno-economics
- CFD modelling and design of food and beverage process equipment
- Instrumentation and process automation
- Image analysis
- Energy and Water Efficiency
- Refrigeration, HEX networks and Cleaner Production
- Winery & Brewery Engineering
- Winery/Brewery Wastewater Treatment
