His main area of expertise is low-carbon air-conditioning, particularly solar thermal cooling incorporating the desiccant evaporative cooling system. He has also expertise in the mechanisation of processes, particularly in the Ag Tech Industry. He has carried out several theoretical and experimental investigations on the dehumidification process, developed innovative desiccant drying systems and invented the non-adiabatic desiccant wheel which has high effectiveness in moisture removal. He has over 20 years of experience in the energy field and successfully carried out several joint projects with internal and external partners, including international collaborators. He received several awards which include an award from the Australian Institute of refrigeration, air conditioning and Heating (AIRAH) for outstanding scholarship in the industry.

He has received external research grants of more than 2.5 million Australian dollars in the past five years which belong to different categories including Cat 1 funding. The details of these projects are given on the research page. He has supervised many research students for PhD and Research master courses.

Currently, he is working on novel cooling technologies such as desiccant cooling incorporating the non-adiabatic desiccant wheel and the dew-point evaporative cooler which is superior to the current finalists' project in the global cooling prize (https://globalcoolingprize.org). He also working on a project on integrated green hydrogen production facility with desalination unit powered by low-cost solar photovoltaic thermal (PVT) systems also.

At present, he is a committee member of the special technical group (STG) for the Renewable Energy Heating and Cooling of AIRAH. He is also the Chair of Engineers Australia’s Bundaberg Regional Committee for the year 2019. He is a member of the editorial board member and reviewer of a few international journals such as Energies, Applied Thermal Engineering, Solar Energy Engineering etc.
