I know Prof. Prasad Yarlagadda for around 15 years since  I joined Queensland University of Technology (QUT), Brisbane as Lecturer in 2007. I still remembered that Prasad welcomed me to QUT in my first day commencing in QUT. At that time, he was leading Built Environment Engineering (BEE) Faculty as Deputy Director, Centre for Built Environment Engineering Research and also Assistant Dean (Research) in BEE faculty. In addition, he was Director, Smart Systems Research theme and Head, Discipline of Mechanical, Manufacturing and Mechatronics Engineering in QUT.
