Rare circulating tumor cells (CTCs) are often present in the bloodstream of those with metastatic cancer, and analyzing these CTCs is useful for clinical diagnostic purposes. We are interested in capturing these CTCs via microfluidics technologies in an antigen-free manner that will supplant current industry standards in CTC capture. [+] Conducted research into microfluidic methods for capturing rare circulating tumor cells from whole blood:• Designed and rapid-prototyped microfluidic structures to improve sample processing throughput and specificity. • Conducted critical experiments using fabricated microfluidic devices to optimize reagent, operational, and usability requirements for external clinical users. • Trained users from corporate sponsor Johnson&Johnson on technology design, installation, and usage. [+] Ensured good laboratory practices and safety as Safety Manager; maintained mechanical equipment, quality of biological reagents, and health of fellow colleagues.[+] Performed phlebotomy, acquiring healthy-donor blood for experiments; over 90% successful draw rate.[+] Managed supply chain and purchasing duties for 20+ employees.

Cornell University

• Selected to jointly oversee approximately sixty students for introductory biomedical engineering course.• Conducted office hours, computational tutorials, and labs covering such topics as DNA electrophoresis, microfluidic fabrication/operation, mammalian cell culturing techniques and cell cytotoxicity testing.

Detailed, working knowledge of biological structural development during morphogenesis can provide understanding of disease paradigms that can affect those structures. We were interested in studying cardiac developmental morphogenesis in avian embryos via micro-computerized tomography, to better facilitate cardiac regenerative treatment strategies. [+] Conducted research into optimal nanoparticle colloid contrast media for optically-gated in vivo cardiac monitoring of avian embryos via micro-computerized tomography:• Performed synthesis, optimization, and characterization of gold nanoparticle colloids. • Tested nanoparticle cytotoxicity, computerized tomography-based contrast enhancement factors, and injection methodology with avian embryonic cultures.

Optical imaging of biological tissues is complicated by factors such as tissue depth, laser interaction with tissues, and camera sensitivity. Injectable contrast agents can ease imaging constraints, but must be biocompatible, easily synthesized, and be specific to tissues of interest. Our group was interested in providing novel substances that can satisfy these criteria. [+] Conducted research into biomedical sensing and in vivo cancer ablation techniques for bioconjugated metallic nanoparticle colloids, utilizing Raman amplification and Surface-enhanced Raman spectroscopy (SERS):• Synthesized gold and/or silver single-core, dual-core, and core-shell nanoparticle colloids with various geometries and bioconjugated stabilizers. • Optimized nanoparticle size, geometry, pH-stability, and magnitude of SERS enhancement factor.
