Biography

Sharma Thankachan received a bachelor's degree in Electrical and Electronics Engineering from the National Institute of Technology Calicut, India, in 2006 and a Ph.D. in Computer Science from the Louisiana State University (Advisor: Rahul Shah) in 2014. After over two years of postdoctoral experience at the Georgia Institute of Technology (Host: Srinivas Aluru) and the University of Waterloo (Host: Ian Munro),  he joined the University of Central Florida, Orlando, as a tenure-track Assistant Professor of Computer Science in 2017. In 2022, he moved to North Carolina State University as an Associate Professor of Computer Science. He is primarily interested in String Algorithms, Compressed Data Structures, and their applications in areas like Computational Biology.
