Research Interests

The pathogenic, Category B bio-threat Rickettsiae (responsible for typhus and spotted fever), initially presents non-specific symptoms, and broad-spectrum antibiotics panels are often ineffective forms of treatment.    My current project at Sandia, in collaboration with UTMB Galveston, involves the ultra-sensitive detection of Rickettsia in blood samples using microfluidic immunoassay techniques. Early detection of the infectious agent facilitates containment and appropriate treatment for the affected patient.

My other research interests involve the integration of biomaterials, micro-technology, and biology.  In particular, I am interested in developing in vitro techniques that will help to quantitatively correlate microenvironment cues (both chemical and biophysical) with the regulation and induction of cellular response (e.g. stem cell differentiation, cell migration, angiogenesis, and autocrine/paracrine signaling).
