I am Yogatheesan (Yoga) Varatharajah, a PhD candidate in Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign. I have previously obtained my master's degree from the same university and bachelor's degree in Electronic and Telecommunication Engineering at the University of Moratuwa in Sri Lanka. I am currently in my 2nd year of the PhD program and I am advised by Prof. Ravishankar Iyer. Currently I am a PhD intern at Google.

My interests span probabilistic modeling approaches for addressing challenges associated with complex, real-world, dynamical systems. In that context, my PhD research focuses on developing probabilistic models and artificial intelligence techniques to address complex clinical challenges, related to the most complex biological system, brain. I have extensive expertise in statistical signal processing techniques and machine learning methods, both in their fundamentals and practical application. I leverage my expertise in both of these areas and clinical domain knowledge to develop unique analytic frameworks that provide actionable intelligence and biological insights. I am thankful to a number of neurologists and neuroscientists at the Mayo Clinic, with whom I collaborate extensively in order to gain domain expertise related to the clinical challenges I work on. My PhD research is being generously supported by the Mayo Clinic-Illinois Alliance Fellowship for Technology based Healthcare Research.

Receiving best student paper finalist award from Dr. Nigel Lovell of the IEEE.

Received the Rambus computer engineering fellowship certificate from dept. head Prof. William Sanders at the annual ECE award ceremony.
