Dr. Harekrushna Behera is an Associate Professor (Research) at the Center of Excellence for Ocean Engineering, National Taiwan Ocean University. Previously, he held the same position in the Department of Mathematics at SRM Institute of Science and Technology, India. He earned his Ph.D. from the Department of Ocean Engineering and Naval Architecture, IIT Kharagpur, and later worked as a researcher at the University of Hong Kong. His expertise lies in fluid–structure interactions and fluid flow stability, covering both linear and nonlinear wave dynamics. He specializes in semi-analytical and numerical methods, including the eigenfunction expansion method, least squares approximation, Green’s function technique, and mild-slope approximation. He has developed boundary element method-based numerical codes to analyze wave interactions with coastal and offshore structures. His research group employs Fourier and Laplace transforms, steepest-descent, and stationary phase methods to study wave generation by bottom disturbances and uses the Chebyshev collocation method for stability analyses.
