The CHIL team

Dr. Ethan Kubatko, Director

I am an Associate Professor in the Department of Civil, Environmental and Geodetic Engineering (CEGE) at the Ohio State University and the director of The Computational Hydrodynamics and Informatics Laboratory (The CHIL).

I obtained my PhD at the University of Notre Dame, where I studied under the direction of Joannes Westerink. Following my time at Notre Dame, I was a post-doctoral fellow at the Institute for Computational Engineering and Sciences (ICES) at the University of Texas at Austin, working with Clint Dawson, before I joined CEGE in 2008.

Omar El Khoury

I'm a postdoctoral researcher in the Computational Hydrodynamics and Informatics Lab (The CHIL) at The Ohio State University. I am working on an NSF project entitled “Hazards SEES: Social and Physical Sensing Enabled Decision Support for Disaster Management and Response.” I am developing an adaptive hurricane storm surge framework. In this project, I collaborate with notable researchers from Ohio State and Wright State University. One of the main goals of this research is the development and application of “next generation” high-performance computing tools that can be used to help guide improvements in coastal management practices and hazard mitigation strategies.

I obtained my PhD in structural engineering from the Ohio State in May 2017. I hold an MS degree in civil engineering from North Dakota State University and a BE degree from Notre Dame University, Lebanon. I have experience in research (+6 years), teaching (+9 years), service (6+ years), and industry (2+ years). My research experience encompasses structural control and optimization, structural health monitoring, finite element methods, computational modeling, structural risk/reliability assessment and management, earthquake engineering, dynamics of structures, stochastic simulations, and numerical methods. I am passionate about advancing STEM education and working on humanitarian engineering, diversity, and service. My long term goal is to bridge academia to the engineering practice.


Younghun Kang

I studied mathematics in undergraduate school and got an M.S. degree in Computational Science and Engineering. My research was focused on numerically solving partial differential equations using discontinuous Galerkin (DG) methods. I focused on theoretical (or mathematical) aspects of DG methods for nonlinear elliptic problems. Recently I started a Ph.D. program at Ohio State and am in the process of learning numerical simulation for storm
surge prediction.







Dylan Wood

I was awarded a B.S. in Physics from Austin Peay State University in 2014 and subsequently began studies at The Ohio State University in fall of 2014, in order to pursue graduate work. I was awarded a Master's degree from Ohio State's Department of Mathematics in 2016 for thesis research on the numerical solution of convection-diffusion problems by implicit-explicit methods.This work was done in collaboration with the CHIL lab, and led me to join the lab and Ohio State's Department of Civil, Environmental and Geodetic Engineering as a Ph.D. student in fall of 2016.

My current research focuses on the development of a coupled storm surge/structural fragility model to accurately resolve flood defense system failure mechanisms in large-scale hydrodynamics models and to reliably assess risks to areas protected by such systems, especially during tropical cyclone events.





Yilong Xiao

I was born in China but moved to Singapore in my early youth and became a citizen there. After obtaining a BS in Environmental Engineering and an MS in Civil Engineering at the Ohio State University, with a majority of the completed coursework on water chemistry, I am currently working on my PhD, which focuses on solving unsaturated flow problems using a local discontinuous Galerkin finite element method.

I have a passion for video editing (developed from past work experience under the Department of Engineering Education) that I now often practice as a pastime. While being unreserved in sharing my ideas and expertise, I generally display an introverted personality, reflected in a preference of working quietly by myself. (Translation: "Leave me alone, Omar!")





Ben Yeager

I graduated from Ohio State in 2011 with a bachelor's degree in Civil Engineering before joining the C.H.I.L. while studying for a master's degree. My master's thesis research focused on efficiency improvements for discontinuous Galerkin finite element methods. I developed new time steppers and numerical integration rules that reduced the total number of operations required to run a discontinuous Galerkin model. After completing my master's degree in 2014, I moved to England, where I studied for a Ph.D. in the Earth Science and Engineering department of Imperial College London. My Ph.D. research involved working closely with researchers at the British Antarctic Survey to perform finite element modeling of ocean circulation beneath ice shelves.

I submitted my dissertation in early October and am currently awaiting my defense later this year. In January, I plan to begin a postdoctoral research position at New York University, where I will continue to model the sub-ice-shelf ocean. In the meantime, I am working in the C.H.I.L. once again, assessing time step constraints for some particular time steppers when paired with discontinuous Galerkin methods and developing new numerical integration rules for entropy-stable discontinuous Galerkin schemes.
