He leads the Blue Skies section (department) of IEEE Cloud Computing, where his principal role is to identify and write about most important, cutting-edge research issues at the intersection of multiple, inter-dependent research disciplines within distributed systems research area including Internet of Things, Big Data Analytics, Cloud Computing, and Edge Computing.

Before moving to Newcastle University, he was Julius Fellow (2013-2015),  Senior Research Scientist (equivalent to Senior Lecturer in Australian/UK University Grading System) and Project Leader in the Digital Productivity and Services Flagship of Commonwealth Scientific and Industrial Research Organization (CSIRO – Australian Government’s Premier Research Agency).  Prior to that, he was a Senior Research Associate (Lecturer level B) in the School of Computer Science and Engineering, University of New South Wales (UNSW).

Dr. Ranjan has a Ph.D. (2009) from the Department of Computer Science and Software Engineering,  the University of Melbourne. The computing department at Melbourne is currently ranked #13  as per QS World University Rankings by Subject 2015/2016 – Computer Science.

Dr. Ranjan’s research excellence is evidenced by following recognitions and awards.

  • He was conferred 2018 IEEE TCCPS Early Career Award.  This award annually recognizes only one researcher from either academia or industry who has demonstrated outstanding contributions (publications, citations, grant record, community service) to the field of Cyber-Physical System (CPS).
  • Moreover, he was also conferred 2016 IEEE TCSC Award for Excellence in Scalable Computing (Middle Career Researcher) in recognition of his research leadership in terms of quality of publications, citations, community service, teaching, research supervision, and grant record.
  • One of his journal papers has received “2009 Outstanding Paper on New Communications Topic Award” from the IEEE Communications Society, USA.
  • He received “Best Paper Award” from IEEE HPCC 2013 Conference for his seminal work on extending traditional data analysis algorithms to detect access patterns for massive data processing applications.
  • The IEEE Systems Journal selected his paper for 2018 Best Paper Award of the IEEE Systems Council. This award is given annually to the papers deemed the best among those published in the IEEE Systems Journal during the preceding calendar year.
  • In 2011 University of New South Wales conferred “Goldstar Award” recognizing his excellent research outcomes.
  • Julius Career Award” was given to Dr. Ranjan by his current employer CSIRO for his exceptional publication record, leadership potential and ability to attract talented Postdoctoral Fellows and Ph.D. Students.
  • Recently (April 2014), he was judged as one of the 3 finalists for the “2014 ICT Young Professional of the Year Award” (a Nationally Competitive award Administered by Australian Government for recognizing excellent work in the ICT sector).

During 2001-2002, he worked as a software engineer (research intern) on a very prestigious project of  Physical Research Laboratory (PRL), India. PRL is a National Research Institute for space and allied sciences, supported mainly by Department of SpaceGovernment of India. In particular, he worked on the project titled “Software Development for Characterisation of Detectors of SoXS payload, and Image Processing and Data Analysis acquired from SoXS mission.” This software was used to analyze the data sent by the SoXS (Solar X-ray Spectrometer) payload of the GSAT-2 satellite.

He is an Australian Citizen (through naturalization),  Overseas Citizen of India, and Tier 2 (General) UK migrant visa holder. He was born in a very small village (Hakimpur) located in the Vaishali District of the Bihar State Province of India.
