Materials and Devices for Flexible Electronics            (University of Texas at Dallas)
While at the University of Texas at Dallas I have been working on the development, modeling and physical, electrical and chemical characterization of new materials and devices for flexible electronics. I'm currently supervising 3 Post-docs and supervising/co-supervising 7 PhD and 4 M.S students. I'm also the main mentor for 1 visiting faculty and 3 visiting scholars (1 year).

Advanced Materials for Silicon-based devices            (Texas Instruments/SEMATECH)
During my tenure at the Silicon Technology Development Group of Texas Instruments I was engaged in the development of alternate high-k gate dielectrics, alternative metal gate and shallow trench isolation technologies for complementary metal oxide semiconductor (CMOS).

Dielectric and Oxide Thin Films  (University of North Texas, USA and Universities in  Mexico)
During my graduate studies I was engaged in developing alternate gate dielectric materials for CMOS, including its growth as well as its physical and electrical characterization. I also developed II-VI semiconductor and transition metal oxides thin films for solar cells and thermo-chromic and electro-chromic applications.
