R&D Scientist, Research and Development
2005 - August 2009 CardioMind Sunnyvale, CA

· Responsible for all aspects of development, loading, design, and testing of drug-coated stents for treatment of coronary artery disease; coordinating activities with 2 outside vendors (drug and polymer coating) as well as internal efforts within R&D. Responsible for the development, design, and identification of appropriate methods for Cardiomind’s drug eluting stent (DES) program in accordance with FDA regulations.
· Supported development of the drug eluting stent (DES) program and led evaluation of alternate carriers/polymers (durable and biodegradable), alternative drugs and other drug delivery mechanisms.
· Managed drug coating characterization test method development by outside test laboratory and possible method transfer to other laboratory or to Cardiomind.
· Responsible for coordinating and analyzing drug release and polymer integrity data including preparation of DES stents for subsequent animal chronic studies.
· Oversaw clinical DES coating runs for CARE II clinical trial, including stent and coating characterization, conducting shelf life tests and examination of processes to extend DES shelf life (working with coater vendor), including impact of radiation sterilization on drug content and polymer stability and use of stabilizers and other processing enhancements
· Provided analytical chemistry support for various polymers used in the CardioMind Sparrow Delivery system like HPLC, FTIR, SEM, XRF and DSC.
· 2006- 2009: Additional responsibility of providing QC/QA support for Pilot manufacturing. Provided review of stent documentation, inspection, of both DES and bare metal stents builds, as well as pilot clinical builds. including the radiopaque coating process used in the Sparrow Stent.
· Supported CardioMind’s ISO 13485 certification and recertification efforts with internal audit review of Quality System.
· Carried out feasibility study to transfer all analytical processes and testing necessary to conduct drug release verification in house. Additionally, evaluated cost/benefit of bringing analytical chemistry test capabilities in house.
