● Develop processes for the manufacturing of oligonucleotide products using a variety of synthesizers, cleavage and deprotection, HPLC purification, MS, Spectrophotometer, liquid handlers, etc.

● Work with team to investigate trends, conduct root cause analysis, implement corrective action for processes and collaborate with departments across the organization such as suppliers,operations, logistics,QA,EHS to resolve technical issues and support products.

● Present research findings and analysis in meetings, wrote technical reports and BOMs.

● Assist in the verification process and transfer of the new products in manufacturing labs. Coopervision, R&D, Pleasanton, CA Oct. 2 005 - Dec.2016 Senior Research Associate, 2008 - 2016

Research Associate, 2005 - 2008

● D eveloped novel copolymers for contact lens including synthesis of in house polymer, incorporation of new raw materials, toxicological assessment, formulation “screening,” optical lens design, molding, casting, curing, demolding, extraction of residuals, final hydration, packaging and sterilization.

● E xpert in material analysis techniques on incoming raw materials, in-process samples, finished products and stability samples.

● E valuated results, identified the root cause of undesired property, polymer synthesis or raw materials and drew conclusions leading to product improvement and finalization.

● E xperienced working on multiple projects from bench scale to pilot to manufacturing sites.

● T rained other team members in lens formulations and fabrication techniques and safety procedure.

● L ed group projects and presented research findings and analysis in meetings and forums.

● Managed lab safety tasks in order to reduce recordable accidents and coordinated all lab equipment setup and calibration with external vendors.

● S erved as a member of safety committee to audit labs and to direct lab manager to correct identified problems.

● E xemplified leadership by coaching and inspiring fellow employees to reach company-sponsored wellness goals, resulting in recognition as one of Bay Area’s Healthiest Employers. Thermo Fisher Scientific, P leasanton, CA May 1997- June 2005 Scientist, 2000 - 2005

Chemist, 1997 - 2000

● D eveloped and manufactured Kit Oligonucleotides following SOPs in compliance with GMP, followed by HPLCs (Ion Exchange and Reverse Phase) purification, quantitation, characterization and UV/Vis Spectrometer ensuring production activity and in process quality control.

● P erformed a ssays on nucleic acids, arithmetic calculation to determine the desired concentration in the formulation process.

● I mproved manufacturing processes and shortened production lead-time by checking ongoing production runs to identify and solve instruments problems, t roubleshooting and m aintenance.

● R eviewed and edited SOPs regularly to ensure relevancy with work practice.

● C oordinated the implementation of a 5S Process Excellence Program.

● C oordinated the safety program updating personnel on safety issues and training, and took measurements to reduce recordable accidents.
