Bio:

Dr. Hieu Nguyen was born in a small village in Thai-Binh, a northeastern province in Vietnam. He graduated from the College of Science, Vietnam National University, Hanoi, in 2003 with a Bachelor of Science degree in Mathematics. He then obtained his Master of Arts and Ph.D. in Mathematics from the University of California, San Diego, in 2006 and 2010, respectively. Before joining FUV in August 2022, he was a lecturer at Duy Tan University from 2016-2022 and a postdoctoral scholar at various institutions in the US and the EU from 2010-2016.

His research focuses on formulating, analyzing, and developing numerical algorithms to solve partial differential equations, especially at large scales on supercomputers. He is also interested in optimization algorithms in Machine Learning and their applications in Geoscience, Civil Engineering, and Traffic Monitoring and Management. Particular applications of his research include simulations of earthquakes, surface-subsurface hydrology, multiphase flows in porous media, prediction of landslides, soil erosion, and estimation of physical properties in civil engineering.

In addition to being an active researcher, Hieu is also an enthusiastic educator. He strongly believes in active learning and learning-by-doing. His courses are integrated with real-life and research problems to make them as relevant and interesting as possible. Not only is he approachable in the classroom environment but also outside of classes. He constantly looks for motivated students to join him on projects in computational mathematics and machine learning.
