Bio:

I believe that it is possible to seamlessly integrate machine and the human body by understanding biology at the cellular and molecular level. My diverse education and research background provide a unique combination of knowledge for engineering new devices that interface with the human body, particularly for neural interfaces. My B.S. in Biochemistry and Molecular Cellular Developmental Biology provide me with the fundamental building blocks that enable intelligent bio-design. For example, I worked on the development of a single electron transistor through understanding molecular structure, bio-templating, and bio-mimicry. This foundation was the basis of my graduate study in improving implantable neural interfaces. I developed strategies to insert soft polymer probes into the brain using organic functional group surface modifications to appropriately change surface tension. Additionally, I engineered a novel implantable neural probe with sub-cellular features, improved flexibility, bio-mimitic surface modifications, and an improved recording site material. Further, I investigated strategies to reduce insertion damage through examining the blood brain barrier using advanced in vivo multiphoton technology to select preferred insertion positions. By using these strategies, we can tease apart and evaluate the individual contributions of variables that affect chronic electrode functionality so that we can develop better next generation devices. Finally, my experience with Fontis also demonstrates that my foundation and background is not only limited to neural engineering, but its principles can easily be applied to other devices that interface with the human body. My diverse background and unique depth in molecular biochemistry and engineering provides a powerful marriage to generate a unique program to develop research tools and medical devices with more intimate biological interfaces.
