Dr. Madhusanka Liyanage: First Sri Lankan to win IEEE Outstanding Young Researcher Award<\/span><\/h2>\n

Source:<\/span><\/strong>Island<\/a><\/span><\/p>\n

Oblivious to the laws of physics and before he could even grasp the meaning of the word velocity, he tried to calculate the speed of the bus he was travelling in, by taking into account how long it took the bus to travel between two lamp posts. He was just seven years old then. By grade three he was trying to calculate the light year longhand. It\u2019s not rocket science, it was just a matter of multiplying how far light travelled in a second, by how many seconds there are in a year. But for an eight-year-old to even entertain such an idea, while his peers were still playing cops and robbers, is uncanny.<\/span><\/p>\n

In any other country he would have been celebrated as a math prodigy. So it came as no surprise when, this year, Dr. Madhusanka Liyanage won the Outstanding Young Researcher Award presented by the Communications Society of Institute of Electrical and Electronics Engineers, one of the biggest engineering societies in the world. The award is presented to the 2nd Best Young Researcher in the region, in Liyanage\u2019s case it is Region 8, which included Europe, the Middle East and Africa.<\/span><\/p>\n

<\/p>\n

Award<\/span><\/p>\n

Research performance of candidates was a major criteria for the Outstanding Young Researcher Award. The number of academic papers published in journals and conference papers produced in the last three years, for example, were graded depending on the \u2018impact factor\u2019 of the publication or conference, with contributions to IEEE journals and conferences receiving extra credit. Citations of work in the past three years is also considered, as well as contribution to the society in the form of the number of conferences or workshops organised and journals edited. Positions held within the IEEE society is given special consideration and Liyanage was elevated to the position of senior member this year. \u201cIt\u2019s not just my award, my team of students, mentors and anyone else who had helped me throughout my career all played a vital role in my success.\u201d<\/span><\/p>\n

\"\"<\/p>\n

Born in Udugama, Galle, in 1985 Liyanage is the youngest in a family of three.\u201dEveryone else in the family have a knack for business.\u201d Both his elder brother and sister took after their businessman father, Sunil Ranjith Liyanage. The youngest Liyanage took after his mother, Magalika Hegodaarchthi. When asked whether his mathematics teacher-mother was influential in his academic trajectory, Liyanage readily admitted that she was a positive influence. He was exposed to math at an early age. His mother still fondly reminisces how the six-year-old parked himself at the back row of her math tuition class trying to solve problems meant for 14-year-olds. \u201cPerhaps the exposure motivated me,\u201d said Liyanage. \u201cMath was the only subject that made sense to me. In fact, I am not good at any other subject.\u201d His uncle bought him the book, \u2018How to become an engineer\u2019 when he was still in grade three, the math problems in which he avidly devoured. \u201cIn fact, I can\u2019t remember a time I wanted to be anything other than an engineer,\u201d chuckled Liyanage.<\/span><\/p>\n

Education<\/span><\/p>\n

Liyanage received his primary education in Udugama Maha Vidyalaya. The grade five scholarship examination results qualified him to enrol in Richmond College, Galle and A\/Ls got him through to the Moratuwa University, where he obtained his B.Sc. Degree, with First Class Honours, in electronics and telecommunication engineering, in 2009. \u201c3G was just rolling out and it was an exciting time to be in the telecommunications field,\u201d said Liyanage. He received a scholarship to Asian Institute of Technology, even before he completed his bachelors. He completed his Master in Engineering (M.Eng.) from the Asian Institute of Technology, Bangkok, Thailand, in 2011. After a year at AIT he moved to France on a dual degree programme, where he obtained a Master of Science (M.Sc.) from the University of Nice Sophia Antipolis, France.<\/span><\/p>\n

In 2004, right after his A\/Ls he represented Sri Lanka in the 45th International Mathematical Olympiad, held in Europe. Since that first taste of Europe, he had been drawn to it and knew then that one day he would make it his second home. In Finland, considered the base of telecommunication with big-name companies like Nokia and Huawei setting up shop there, Liyanage obtained a PhD in communication engineering from the University of Oulu, in 2016.<\/span><\/p>\n

Then his path diverged. \u201cI could opt for a job in the industry or stay in the academic track.\u201d He decided to remain an academic. Between 2015 and 2018 he functioned as a visiting Research Fellow at various institutions such as Data61, CSIRO, Sydney, Australia, the data and digital specialist arm of Australia\u2019s national science agency; Infolabs21, Lancaster University, UK; School of Computer Science and Engineering, University of New South Wales; School of IT, University of Sydney and computer science laboratory LIP6, Sorbonne University.<\/span><\/p>\n

In 2018, he received the Docentship from the University of Oulu, Finland, within 18 months from the PhD, making Liyanage the only researcher to receive the Docentship so soon. He worked as an adjunct professor at the University of Oulu while engaged in his post doctoral studies. He joined the School of Computer Science, University College Dublin (UCD), Ireland, early this year as an assistant professor and Ad Astra Fellow with the prestigious Marie Sk\u0142odowska-Curie Actions Individual Fellowship. The fellowship is one of highly reputed fellowships offered by the European Union.<\/span><\/p>\n

Research<\/span><\/p>\n

Liyanage\u2019s main research interest is telecommunication network, 5G and 6G mobile networks in particular, focusing on network security concerns. \u201cThe major change we can expect with the transfer from 4G to 5G will be the number of devices that will be connected to the system.\u201d He explained that although we only connect mobile devices such as mobile phones, tabs and laptops to the network, the advent of 5G will allow more devices, such as smart wearables, to be connected to the network. 6G will further expand the horizon to include the whole shebang, or Internet of things (IoT). In lay terms IoT is the network of physical objects, referred to here by \u2018things\u2019, that exchange data with other devices and systems over the Internet.<\/span><\/p>\n

\u201cThese new devises don\u2019t have the standard security measures that mobile devises and laptops have, making them more susceptible to cyber attacks.\u201d Liyanage explained that there are only a handful of mobile device manufacturers in the world, consequently all mobile devices have in place stringent security control measures and are required to follow strict standards. \u201cThere is a large number of IoT device manufacturers, and are not bound to follow such strict security measures.\u201d Liyanage explained that such devices are susceptible to cyber attacks and can, in fact, be used as entry points for attacks on the 5G network. \u201cBesides some IoT devices are considerably smaller and, therefore, does not have a lot of processing power. Consequently, they cannot support high power security mechanisms.\u201d<\/span><\/p>\n

Liyanage further explained that even reputed manufacturers of IoT devices, opt out security tests, due to related costs and time constraints imposed by high competition. \u201cA major drawback in 5G is that it is a software controllable network and software based systems are generally more vulnerable than hardware based systems.\u201d He elaborated that 5G is an open architecture platform, which will enable software developers to understand, and possibly manipulate it.<\/span><\/p>\n

What has the potential to make matters worse is that, after all IoT devices are interconnected, the next step will be to integrate all critical infrastructure such as the power grid, transportation network or water managements systems. \u201cThese can be monitored by IoT devices via 5G.\u201d Liyanage pointed out a major security risk arguing that any terrorist or cyber criminal with a decent IoT device could hack into such systems and thereby wreak havoc with any of the aforementioned critical infrastructure.<\/span><\/p>\n

He explained that 6G will enable the integration of Artificial Intelligence into the system. \u201cIt will be a mostly automated, self sustaining network, centrally controlled by an AI. \u201cAI is essentially a good thing as long as it is used for the good,\u201d said Liyanage. But it can also be manipulated to achieve malicious ends, according to him. \u201cFor example, if someone creates a malicious intelligent agent, it can identify loopholes in the system and self perform attacks on it.\u201d The sci-fi like evil AI agent stuff may come off like an episode of \u2018Person of Interest\u2019, but Liyanage maintains it is entirely plausible. Consequently, he reiterated the requirement of straightening out the AI related security issues before considering launching the 6G system. \u201cWe have to consider everything from the data fed to the AI to what kind of effect it will have on the AI and how reliable the AI algorithm will be.\u201d<\/span><\/p>\n

All these maybe years away and will no doubt have repercussions of global relevance. But what are the more immediate threats at individual level when switching to 5G? \u201cIt will have a huge impact on society. So far we only connect mobiles, tabs and laptops to the system.\u201d But with a full-fledged 5G system, expected sometime between 2025 to 2030, a lot more IoT devices will be interconnected via the system. \u201cThese devices can collect a lot of personal information. For example, from cameras on mobile phones to smart TVs, every new device comes with a built in camera. It won\u2019t be long before many strap smart wearable that store health information.\u201d Liyanage pointed out that this wealth of personal information, most of which is uploaded on to cloud services, can easily be stolen. \u201cThis is a major violation of privacy.\u201d He emphasised that, at an age when everyone in society is connected to the system most of the time by at least one device such as the mobile phone a proper privacy protection mechanism should be put in place to counter such privacy violations.<\/span><\/p>\n

When asked whether 5G or 6G posed renewed individual financial security threats, Liyanage pointed out that such information is already available on most devices connected to the 4G system. \u201cBut they are connected through personal Wi-Fi, which is safe as long as you maintain it password protected.\u201d<\/span><\/p>\n

Blockchain applications, another research area that appeals to Liyanage, may just provide the solution for a host of these security issues. For those uninitiated in telecommunication networking, Blockchain applications are cryptography used to secure transactions made using cryptocurrency. Blockchain technology became popular a decade ago and gained momentum because of Bitcoin cryptocurrency, the digital equivalent of money. It may be just a bunch of ones and zeroes but daily transactions using cryptocurrency can amount to billions.<\/span><\/p>\n

\u201cBitcoin cryptocurrency is a beautiful innovation but what\u2019s more interesting is the technology used to secure transactions made using cryptocurrency, blockchain, because of its applications in other areas such as telecommunication.\u201d Liyanage pointed out that some of the pressing security issues of 5G and 6G can be solved using blockchain technology. \u201cThe biggest advantage of Bitcoin cryptocurrency is that it eliminates the third party. For example, if two people want to make a transaction, it has to be done through the bank. But with Bitcoin, transactions can be made direct.\u201d<\/span><\/p>\n

So, what are its implications for telecommunication? \u201cThe same concept can be used in telecommunication,\u201d explained Liyanage. \u201cThere are certain instances where a third party is required. Roaming is a case in point.\u201d Roaming allows the use of a mobile connection while outside the range of its home network by connecting to another available network in the country of travel. \u201cTo achieve this, the home country service provider should have an existing agreement with the visiting country operator.\u201d When two parties who do not know each other want to enter into an agreement, in order to ensure that both parties keep their end of the bargain, a trusted neutral third party must intervene, and be paid for, for their pains. Blockchain can offer this trust and is far more preferable to a physical third party as is requires no commission. \u201cAnywhere a third party is required, they can be replaced by a blockchain.\u201d<\/span><\/p>\n

There are many other such applications, according to Liyanage. \u201cIt can be used in service-level or SLA agreements. For example, if a user enters into an agreement with a telecommunications service provider, on his or her own terms, a third party must ensure that both parties keep to their agreement.\u201d<\/span><\/p>\n

Multitasker<\/span><\/p>\n

Liyanage currently supervises nine PhD students and three Master students in four different universities. He is also a visiting Lecturer at Moratuwa University, Sri Jayewardenepura University and Yangon Technological University, Myanmar. In addition to conducting lectures for Undergraduate and master courses at the University College Dublin, supervising postgraduate students, mentoring postdoctoral researchers and functioning as the principle investigator for various national and internal research projects, Liyanage has found time to publish over 100 research articles and three books. When asked how he achieve all this at such a young age, with two masters and a PhD to boot, Liyanage attributes it to his time management skills.<\/span><\/p>\n

\u201cI may not always have my nose in a book, but I manage my time efficiently.\u201d He takes after his parents, who happen to be early birds, waking up at 4 am. From four to eight or nine he dedicates to research work. \u201cHaving the satisfaction that I have done my job for the day, I can fool around all I want the remaining 10 hours or so. I think life needs this kind of balance.\u201d<\/span><\/p>\n

Unlike Sri Lankan students, who are forced to work in the government or corporate sector while reading for a master or PhD, Liyanage didn\u2019t have to sacrifice valuable time on a job unrelated to his field of work. Liyanage was paid to do research and this, he points out is the fundamental difference between European countries and Sri Lanka. \u201cI hardly know any full-time PhD students in Sri Lanka. Most of them are forced to lecture. PhDs require dedication.\u201d He admitted that his academic load of University College Dublin is comparatively low allowing him to dedicate more time to research. Usually a lecturer is required to teach three modules per year, but because he is an Ad Astra Fellow, he is required to teach only one module. \u201cIn a bid to encourage research, University College Dublin hired 100 lecturers over a four-year period as Ad Astra Fellows, who would have limited academic load.\u201d<\/span><\/p>\n

It\u2019s quite the opposite in Sri Lanka, pointed out Liyanage. \u201cThere are talented students and lecturers in Sri Lanka, but they are overloaded. Some lecturers are required to teach three modules in a single semester.\u201d He also pointed out the lack of research funding and grants. \u201cIt should come from either the government of the corporate sector. To attract good PhD students remuneration equivalent to industry sector salaries must be offered.\u201d<\/span><\/p>\n

Liyanage\u2019s achievements are not solely academic. The multitasker also has a patent to his credit. During a short stint at General Electronics, their branch in Italy wanted to replace the wired communication mechanism between the head and the tail of trains built by them, with wireless communication. \u201cBecause wired connections were a hassle when changing carriages. But wireless communication mechanisms are relatively less secure, because open air transmissions can be intercepted.\u201d Liyanage built a secure wireless communication mechanism, which was patented. When he is not engaged in research, teaching or supervising, Liyanage likes to travel.<\/span><\/p>\n
