WORK EXPERIENCES

2007, 03 - present Senior Research Scientist, Chemical Development, Albany Molecular Research, Inc. (AMRI), Albany, NY

• As a leading chemist, successfully improved a problematic process into a highly robust and cost-effective one that reduced overall 5 steps to 2 steps, reducing operation time by 75%, saving over one million dollars for 2 100 kg campaign.

• Completed a high profile project from a major biotech pharmaceutical company that demands process development, optimization, and essentially to manufacture multi-kilograms of high potency API under cGMP conditions within an extremely compelling time line. The improved process was much more reliable and the overall yield (4 steps) was increased from 50% to 62%.

• Excelled multiple challenging projects that often transferred from customers from a first time customer that requires preparing an impurity, which originally was synthesized on mg scale through 7 steps involving tedious multiple chromatography purification. Again by applying my solid synthetic skill and expertise, I redesigned the synthetic route, completely removed chromatography, increased the overall yield by 22 fold, and delivered 10 times quantity of the product. As a result, the customer was won over and came back to AMRI with a 1.5 million dollars contract.

• Completed a highly challenging project that a competitor failed to deliver. The project urgently demanded to deliver 100 g product that was originally synthesized via 10 synthetic steps, one of which involved a carbonylation of a poor substrate under supercritical CO2 conditions. By applying my solid organic synthesis skill I revised the synthetic route (shortened the 10 steps synthesis to 6 steps) and finished route scouting, scale-up and achieved to deliver the product within 2 months.

• Developed from scratch robust processes for production of multiple challenging polymer-API conjugates used for targeted drug delivery system, through which established a solid business relationship with the customer and generated 3 million dollars revenue.

• Increasing responsibilities over the years including supervising junior chemists, management of projects, and communication within company and among customers

• Good documentation skill including writing bids, batch records, and SOPs

2003, 01 – 2007, 2 Research Assistant, Ph.D. candidate, McGill University, Chemistry Department, Montréal, QC, Canada

• Highly independent researcher directed and developed my own research program including rational design of bioactive molecules, synthetic route design and scouting, execution of multiple-step synthesis

• Honored with 5 university and departmental awards for excellence in research of my Ph.D program

• Teaching organic chemistry laboratories for three consecutive years with excellent feed-back and recognition from the course directors and students

1999, 07 -- 2002, 05 Research Associate, Ohio State University, Dentistry College, Columbus, OH

• Initiated and wrote proposals for industrial collaborators including 3M corporation (St. Paul, MN) and Kerr Corporation (a subsidiary of Syborn Specialties, OC, CA)

• Completed 3 projects sponsored both by NIH and industrial collaborators: (1) Design and synthesis of oligomeric oxazolines and their application for high performance thermoplastics; (2) Photo-polymerizable polyhedral oligomeric silsesquioxane (POSS) nanocomposites for biomedical applications; (3) Hyperbranched/dendritic polyester-derived visible-light-cured (VLC) composites for dental restoration
