DIVISION OF RESEARCH AND DEVELOPMENT

Senior Biochemist, IMMULITE (February 2010 – January 2012)

• Collaborated with Siemens Los Angeles Quality Control Department for the successful transfer of all immunodiagnostic platforms to New York

• Directly collaborated with in-house Quality Control Department to Streamline Los Angeles’ specific SOP’s to Tarrytown Work Instructions, validated all immunodiagnostics platforms and submitted final report

• Developed the Intact Para-Thyroid Hormone Immunoassay for the IMMULITE Platforms following GMP, GLP and SOP’s

• Using DOE’s, designed, performed and analyzed all data collected. This includes functional sensitivity, method correlation, stability, manufacturing robustness, interferences among other parameters.

• Manufactured bulk assay Calibrators, Master Curve Material, Adjustors, Controls, and Medical Decision Pools, following GMP and GLP methods.

• Co-wrote and presented final report to review board for clearance of scale-up assay manufacturing which included feasibility, annual stability reports and validation report

• Collaborated with the Regulatory Affairs and Labeling department at Siemens Healthcare Diagnostics for the proper submission of all necessary documents to the FDA and for Japanese registration. This included writing the IVDD, Pre-IDE, 510(k), MSDS, FFU, and assay disclaimers.

• Worked closely with the Labeling and Design departments to finalize all immunoassay packaging components. This incorporated writing a test kit packaging Grid, safety-related disclaimers, Quality Control insert (QC), design packaging layout and in some instances changes to existing packaging kits. Final approval signatures were attained in a board meeting in which I was the R&D representative.

Critical Project for IMMULITE Analyzers: Validation of Scale-Up V-Mixer

Tarrytown, NY. June 2011- October 2011

Siemens Healthcare Diagnostics

In June 2011 I took over the responsibility of the V-Mixer validation. The V-Mixer is the only Scale-Up machine required for the manufacturing of all IMMULITE beads. Having a Validated V-Mixer was mission critical to the sustainment of the R&D department with assays quickly approaching the scale-up phase. Through carefully designed experiments past validation failures were determined. After implementing changes the validation protocol was initiated and successfully completed in October 2011.

Critical Projects: Pre-Clinical trial for Procalcitonin

Chicago, IL. April 2009 – April 2009

Swedish Covenant Hospital

In 2008 I proposed a theory that an intermediate molecule was present in the progressive digestion of Procalcitonin that would be critical to the method comparison to the predicate assay. I developed the PCT Immunoassay using a secondary antibody identifying this intermediate fragment. The purpose of the Pre-clinical trial was to execute a method comparison study against the Vidas Kryptor assay to prove my theory. This was a critical step in the development cycle of the PCT assay. Over 200 fresh disease samples were analyzed on both platforms. The data proved that my theory was correct and the PCT immunoassay was cleared for scale-up manufacturing.

Key Contributions to the eTSH3 immunoassay:

Tarrytown, NY. January 2007 – June 2007

In 2007 the development of the ADVIA Centaur eTSH3 assay had to be delayed. It was observed that as the eTSH3 reagents aged the baseline signal increased. This phenomenon affected the sensitivity of the assay causing many failures at the low end. I devised a comprehensive evaluation of the assay architecture to decipher the cause of the increasing low end signal and concluded the cause to be the binary reagent. Further studies confirm my findings and corrective actions allowed the company to move forward with the manufacturing of the eTSH3 assay.

DFSS Project: The enhancement of the Para-magnetic Particles using DFSS tool

Walpole, MA. April 2007 – June 2007

Manufacturing

In 2007 I was selected to a team of scientist to optimize the coupling of antibody to para-magnetic particles (PMP) under manufacturing conditions. The purpose of this project was to potentially reduce the amount of antibody that was coupled to the PMP without sacrificing assay performance characteristics. After completion of the study data was collected and final analysis demonstrated more robust assays with increase performance characteristics. This has allowed the company to cut cost on all assays that use the PMP’s.
