EDUCATION
B.S., School of Engineering, Columbia University (May, 2003)
Major: Biomedical Engineering
Minor: Mechanical Engineering
Senior Thesis Topic: “Polymer Encapsulation of Cells for Controlled Delivery of Drugs”
RESEARCH INTERESTS
Polymer-based drug delivery systems; Micro-total analysis systems, microfluidics and biological microelectromechanical systems (bioMEMS) design and fabrication; microencapsulation of cells for drug delivery applications; characterization of material and mechanical properties of soft tissues, including but not limited to, permeabilities, stress relaxation, and streaming potentials; Bioreactor design and fabrication;
EXPERIENCE
Columbia University Microelectronics Sciences Laboratories
June 2003 – Present: Serve as a part-time, non-matriculated graduate research assistant, under Professor Richard Osgood, Jr., characterizing the effects of elemental doping, by ion beam, on selected ferroelectric materials by transmission electron micrographing and ion beam analysis including Nuclear-Reaction Based Depth Profiling (NRBDP), Rutherford Backscattering Spectrometry (RBS), Particle Induced X-ray Emission (PIXE). Using dopants to achieve Crystal Ion Slicing (CIS) of these materials, highly sensitive sensing and actuating films have been developed for inclusion in MEMS delivery and analytical systems in house at Columbia (see publications).
Sept. 1999 - Jun 2001: Served as an undergraduate research assistant under Professors Richard Osgood, Jr. and James Yardley. Developed piezoelectric actuating systems, microfluidic circuits for bioMEMS applications, and developed a novel technique for surface treatment of various silicones with reactive ionic species via ion implantation through engineered attenuating films (see publications).
Materials Diagnostics, Inc.
May 2003 – Present: Serve as a junior research associate; operate the Dynamitron, Tandem, and Extrion linear particle accelerators. Responsible for Rutherford Backscattering Spectrometry (RBS) and Particle Induced X-ray Emission (PIXE) analyses, as well as ion implantation.
(see publications)
Columbia University Orthopaedic Research Laboratories
Jun. 2001 – Dec. 2002: Served as an undergraduate research assistant, independently developing a High Pressure Nano-Perfusion (HPNP) Bioreactor for characterizing strain dependent permeability, streaming potentials, stress relaxation, and drag-induced compaction in both ordinary and engineered soft tissues.
State University of New York at Albany Sept 2000- PRESENT: Serve as a part-time machinist.
Hewlett Packard, Inc.
Jun. 1999 - Aug. 1999: Designed and built a micro-electromechanical, liquid chromatography system under the guidance of Dr. Alain Kaloyeros. The device is now in use at the biochemistry core of the Wadsworth Research Laboratories of the New York State Department of Health.
New York State Center for Advanced Thin Film Technologies
Sept. 1998 – Jun 1999: Played an integral role in the development of a chem-optical thin-film gas sensing system for detecting small quantities of ambient carbon monoxide. Specifically, designed and built a miniature, confocal system of lenses, which introduced monochromatic light into the system for spectroscopic measurement, along with the optical stages upon which the thin films were deposited.
New York State Department of Health’s Wadsworth Laboratories Jun. 1998 – Sept. 1998: Modeled protein superstructure and characterized protein denaturation in thermophilic, light-harvesting bacteria from the hot springs of Yellowstone National Park. The work was sponsored by, and conducted under the supervision of Dr. Robert MacColl. (see publications)
