Arif Khan is a postdoctoral researcher in complex systems research group at the University of Sydney. His key research interests are in the fields of complex networks, data mining, healthcare informatics, computer graphics and visualisation. He is currently working in Health Market Quality research stream at CMCRC as part of industry partnership with the university. His present research focus is to understand the chronic disease progression using healthcare data and develop a predictive framework based on that. Chronic diseases like type 2 diabetes, cardiovascular diseases etc. incur a significant burden on the healthcare system. Despite the fact that a healthy lifestyle and routine checkup can prevent or delay the chronic disease onset, many patients are unaware of their progression towards chronic conditions. Often the reason is – these diseases progresses slowly and often without explicit syndromes. However, in many cases, these diseases occur together as they have similar biological and environmental factors. Therefore, it would be fascinating if we can understand these factors from the patients’ medical history and predict the risk of chronic diseases based on that. One of the key ways to do that is to look at the routinely collected administrative healthcare data such as hospital admission data which contains diagnoses and other socio-demographic information of patients. Arif’s research focuses on looking at the patterns in this data and generating disease-related networks from them. He is utilising data mining methods, social network and graph theory to understand disease progression from these networks and predict the future pathway of the patient i.e., to predict how likely the patient will follow the chronic disease pathway. Arif completed his B.Sc. in computer science and Engineering from Bangladesh University of Engineering and Technology in 2011. He has worked as a Broadcast Engineer and software developer in a Satellite Television company, gathering industry experience on software development, satellite communication, IT management and computer graphics. Subsequently, he has worked as a lecturer in Computer Science at BRAC University, Bangladesh and then moved to the University of Sydney to do his PhD during 2013-2016. He has authored several research articles in reputed international journals.
