Received a B.Sc. degree in Physics Engineering in 2002 and M.Sc. in Electronic Systems in 2005 from the Tecnológico de Monterrey, Mexico. Received a M.Sc. in Optics in 2008 and Ph.D. in Optics in 2010 from the Institute of Optics, University of Rochester in NY. Early in 2003 I joined the Photonics and Mathematical Optics Group (PMOG) and started working as a research assistant under Dr. Julio C. Gutierrez-Vega, where I was involved in research in analysis of mode competition in unstable optical resonators (my Master's dissertation), numerical methods for propagation and non-diffracting beams. In 2005 I started the Ph.D. program in optics at the Institute of Optics in Rochester NY and joined the Phase Retrieval and Imaging Science group (PRAISE), headed by Dr. James R. Fienup. My doctoral research was mainly focused on the development and advance of phase retrieval (in particular ptychography) and holography for application to high-resolution lensless imaging and wavefront measurement at x-ray wavelengths [+]. In 2010 I held a postdoctoral appointment and in 2011 started as beamline scientist at the cSAXS beamline, Swiss Light Source, Paul Scherrer Institut.

PhD Thesis: Methods for coherent lensless imaging and x-ray wavefront measurement

Operation and further development of the cSAXS beamline, including development of new measurement and analysis methods, procurement of equipment, and coordination of work with PSI technical groups. Development and management of research projects with focus on coherent X-ray scattering and small-angle X-ray scattering, including project applications and the acquisition of third party funding. Publication of research results in peer-reviewed journals, conferences and symposia. User support at the cSAXS beamline, creation and development of collaborations with external partners, and supervision of doctoral students and technical staff.

My research is focused on the development and advance of techniques and image reconstruction algorithms for X-ray coherent diffractive imaging, ptychography and scanning small angle X-ray scattering (sSAXS). In particular I am interested in the extension of these techniques to high-resolution 3D (or higher-dimensional) imaging, with applications in biological and materials science samples, such as bone, cement and catalysts.
