Brief Bio

My Name is Amiya Patanaik

I am currently a post doctoral research fellow at Cognitive Neuroscience Laboratory, Duke-National University of Singapore, headed by Prof. Michael Chee. Currently I am involved in the multi-modal study of sleep. Many interesting patterns are expected to be uncovered connecting vigilance, attention, memory and behavioral performance with different micro-architectures of sleep. I am also looking at possible predictive markers of vigilance and drowsiness. I did my graduate studies at Nanyang Technological University - Singapore under the supervision of Dr. Kwoh Chee Keong. My broad level interests lie in statistical modeling and machine learning. I got my bachelors with honours in energy engineering from Indian Institute of Technology - Kharagpur. I worked at Solar Semiconductor Pvt. Ltd. in the capacity of system integration engineer for one year where I was responsible for the design of solar power plants. I am founder and director of Arkenstone Technologies Pvt. Ltd., a company specializing in software development and analytics. I am a director at Sustainable Growth Initiative, a section 25 non-profit specializing in energy consulting and analytics. There are no clear boundaries between my professional and personal interests; In my own time I like to explore the broader applications of my research. I am an amateur photographer who loves to travel. In my spare time I love watching movies and TV series, reading, cooking and talking with friends on myriad of topics. I love to swim and play tennis and squash.
