Mr. Luis A. Alemán-Castañeda Profile

Luis A. Alemán-Castañeda

Researcher at Institut Fresnel

SPIE Involvement:

Author

Area of Expertise:

ray tracing , uniaxial materials , birefringence , polarization

Currently I am finishing my major in physics at the Universidad Nacional Autónoma de México, UNAM, and work with Dr. Martha Rosete in ray tracing in uniaxial materials at the CCADET, UNAM.

I have studied abroad for one semester at the University of Oslo, UiO, and participated in an undergraduate research program at UC Davis modeling heavy ion collisions under Dr. Manuel Calderon de la Barca.

I enjoy programming and know how to program in C++, julia and C.
