I led a cross functional project within manufacturing and process development looking to improve mixing for parenteral drug products and buffers in single use bags. I designed and built an In-Line Refractometer to continuously sample multiple sections of a mixing vessel to determine homogeneity of the solution in real time, which can be used to set proven acceptable ranges for every molecule. I characterized the minimum volume and mixing speed ranges for different volumes in a 1000L mixing… Show more I led a cross functional project within manufacturing and process development looking to improve mixing for parenteral drug products and buffers in single use bags.

I characterized the minimum volume and mixing speed ranges for different volumes in a 1000L mixing vessel to increase flexibility of the vessel as batch requirements change. I designed and built a probe to quantitate velocity in different regions of a cubic mixing vessel through integrating a strain gauge and Wheatstone bridge onto a probe. I also wrote studies and technical reports in accordance with cGMPs and GDPs.

Aug 2017 - Dec 2018
Undergraduate researcher at Texas A&M University, working with an engineering PhD candidate to investigate the biochemical effects of mechanical forces at the cellular level and their contributions to the development of lymphatic diseases. This is being achieved through the design and build of a bioreactor to expose lymphatic endothelial cells to fluid shear stress and stretch simultaneously.

I worked on two ocular research projects at Texas Children's Hospital and Baylor College of Medicine. On one project, I worked on a novel ocular drug delivery system. I manufactured hydrogels with nanoreservoirs for drug loading. The hydrogels looked and felt like a contact lens, but slowly dissolved while releasing the loaded drug. For the second project, I worked to determine if the carboxy-terminal G3 domain of the protein versican, found in the vitreous of the eye, increases… Show more I worked on two ocular research projects at Texas Children's Hospital and Baylor College of Medicine.

For the second project, I worked to determine if the carboxy-terminal G3 domain of the protein versican, found in the vitreous of the eye, increases transgene expression in normal and cancer cells. This has potential impacts on transgene expression of suicide gene therapy to treat patients with retinoblastoma.
