Background
I joined the Curtis Lab in October of 2010 after working for two year in Texas A&M Health Science Center in Houston. In Texas A&M under the guidance of Dr. Amendt, I did research in the mechanism that control craniofacial development. Prior to working in Houston I received my B.Sc. in Biotechnology Engineering from ITESM in Monterrey, Mexico.

Projects
Low-cost Plant Propagation Bioreactor Development using Cacao: This project has the goal to develop low-cost bioreactor systems that will enhance the ability to utilize tissue culture to improve agricultural plant productivity. The research will also focus on finding and isolating the genes responsible for embryogenesis and through transient gene technology developed by Dr.Curtis' lab be introduce to our model plant, Cacao. The genes associated with plant embryo formation will be identified by examining patterns of gene expression during somatic embryogenesis by techniques such as DNA microarrays. This project is a collaboration between the laboratories of Mark Guiltinan/Siela Maximova in Horticulture and Dr. Curtis' Laboratory in Chemical Engineering. This projected is funded by the NSF.
