Paredes Tobar, Lenin Marcelo individual record
Assistant Professor
Positions:
overview

Marcelo Paredes is an assistant professor in Ocean Engineering Department at Texas A&M University. Paredes joined TAMU after five years at MIT as a research scientist in the Impact and Crashworthiness Laboratory (ICL). Paredes obtained his Ph.D. in 2012 from University of Sao Paulo (USP) in the area of fracture mechanics. His research interests lie in the interface of physics and mechanics to develop predictive analytical and numerical models for solid materials (e.g. metals) with special application to ductile crack propagation in thick-walled components and stress corrosion cracking assessment and ductile-to-brittle transition behavior.
