Student Profile: Girish Revadigar

Student ProfileWhere are you from and where did you complete your prior studies?

I am from Karnataka, India. I completed Master of Technology (M.Tech) from SJCE, and Bachelor of Engineering (B.E.) from STJIT. Both the institutions are affiliated to Viswesvaraiah Technological University, India. 

Why did you choose to enrol at UNSW?

After completing masters degree,  I worked for six years in IT industry in India. During this period, I gained experience in the design and development of low power wireless networks, and embedded systems. Meanwhile, I developed interest in research and opted to pursue PhD. I was searching for the best-in-class research environment and also the area that matches my expertise and interest. Then, I came to know about the research programs at UNSW Computing, particularly the CySPri and  NetSyS lab, which was a perfect match for my destination.  UNSW is definitely a world leader in many research fields with several distinguished professors and expert researchers. Joining UNSW was a turning point in my life.  I am happy that I took a right decision.   

What is your research about and why are you excited about your project?

In recent years, using tiny wearable devices for personalised health-care, sports, and fitness applications is increasing rapidly. A latest report based on market study has predicted that the wearable technology will reach USD $ 1.6 trillion business in the near future. Typically, these devices exchange sensitive health information over the wireless medium e.g., Bluetooth Low Energy (BLE), which is vulnerable to many types of attacks , such as eavesdropping, tampering the packets, and injecting malicious commands that can lead to fatal causes. Hence,  securing communications between wearable devices is crucial. The data transmitted between the devices must be protected by encrypting the packets using a shared secret key.  Generating the shared secret key on wearable devices is very challenging as the computationally complex  cryptographic mechanisms are not feasible due to resource constraints. My research aims at proposing novel light-weight secret key generation and secure key distribution protocols for wearable devices  by exploiting the unique features of wireless channel characteristics, dual/multi antenna architectures, and onboard sensors e.g., accelerometer. 

My thesis addresses few important problems in an emerging area of research, and I am happy that my research findings are being published in reputed conferences and journals. The most exciting thing is, the national and international awards I received during PhD candidature highlight the importance of my contributions, and this gives me a satisfaction that I am on the right path of research career.

What do you like to do outside of research and academics?

I like singing, playing guitar, and cooking  :).

What are your career goals and future plans?

I am enjoying the research career and  would like to continue the same post-PhD.  I hope to get  many more opportunities in future to contribute to the state-of-the-art, that will be helpful for the society.   My dream is to become a successful researcher.

What advise do you have for prospective students interested in applying for a research degree at UNSW (or CSE)? 

If you are passionate for research, then UNSW is the place to be.  Considering that you are spending 3-4 most valuable years of your life while enrolled for PhD, it is important to ensure  that you will get the best out of it. UNSW provides all the facilities to students to support their research, separate workplaces, dedicated labs for special research groups,  and many scholarships for both domestic as well as international students. There are a number of opportunities to interact and collaborate with the expert researchers from UNSW and also from other reputed industries and research organisations e.g., CSIRO.  UNSW encourages to publish the research papers in top ranked conferences and journals, and each student receives funding to attend the international conferences and present their work.  The academic staff are highly qualified with many years of relevant experience in their research fields, who always support, guide, and motivate the students to conduct high quality research.  The structured PhD program at UNSW with intermediate annual reviews ensure that the student's progress is satisfactory, and he/she completes  PhD in 3-3.5 years.  I strongly recommend joining the research programs at UNSW to succeed in your life as a researcher. 

In short, I would like to say, "Being with the winner, makes you a winner".  Good luck!
