I – Shih Liu. I – Shih Liu (1943) is a Taiwanese civil engineer. He teaches at the Institute of Mathematics of Federal University of Rio de Janeiro.

Education 
I – Shih Liu  studied at the National Taiwan University and graduated with a diploma in 1972. He continued his studies at the Johns Hopkins University (JHU) where he received his doctorate in applied mechanics in 1972 under the supervision of Ingo Müller.

Academic life 
He became assistant professor at the National Taiwan University in 1965, teaching and research assistant at the Johns Hopkins University in 1967, post-doctoral fellow in 1972 and professor at Federal University of Rio de Janeiro (UFRJ) in 1972. He became visiting professor at Carnegie Mellon University in 1976–1977, at University of Bologna in 1982, 1986, at University of Berlin in 1990-1991 and Nagoya Institute of Technology in 2004. He also became visiting professor at Texas A&M University in 2006–2007, at College of Earth Sciences National Central University in 2012 and director pro-tempore at UFRJ in 2000–2002. Since 1972, he has more than 50 mathematical research articles published in peer-reviewed international journals. He is married with one son.

Research areas 
His work deals with continuum mechanics, thermodynamics, relativistic mechanics, rigid body mechanics, elastodynamics, mechanics of deformable bodies, constitutive theories, entropy principle, Lagrange multipliers.
