Job responsibilities

1. Managed Topotecan and Benztropine Mesylate for FDA Abbreviated New

Drug

Applications

a) Developed, optimized, and/or validated the following:

> Stability indicating HPLC assay and impurity methods for

active pharmaceutical ingredient, in-process, final product and

stability samples

> Robust GC residual solvent methods without matrix effect

> Karl Fischer moisture methods

> Efficient freeze drying recipe for commercial manufacturing

by differential scanning calorimetry, freeze drying microscope

and pilot batches using Lyostar freeze dryer

> Other analytical methods for quality control testing and

releasing of active pharmaceutical ingredients, in-process,

final product and stability tests

impurity peaks to acceptable levels

c) Assisted Production, QC, Microbiology, Documentation, Regulatory

Affairs and other departments on manufacturing

d) Prepared method validation protocols and executed validations per

ICH guideline and FDA regulations

e) Tested pilot batches with reference listed drugs to prove that our

generic

drugs the same as innovators'

2. Identified pharmaceutical impurities by LC-MS/MS and NMR

a.) Identified impurity peak in Mitomycin by LC-MS/MS and identified

the cause of impurity peak. Developed a solution to reduce

impurity peak to acceptance level. It saved the company a lot of

money by eliminating rejection lots.

b.) Identified and collected impurity peaks in Fluphenazine

Decanoate stability sample by LC-MS/MS and NMR

c.) Identified crystals in Amiodarone stability samples by LC-MS/MS

3. Developed HPLC-ELSD assay and impurity method for Ibandronate (no UV

chromophore)

5. Studied Pantoprazole sodium stability by HPLC

6. Identified structures of small molecules by LC/MS/MS.

8. Provided technical assistances to coworkers on LC-MS, HPLC, GC, KF and

other analytical techniques

Research Assistant, Cleveland Mass Facility (09/2002 to 12/2007)

1. Worked with various customer samples including synthesized

organic compounds, proteins, and peptides, using Micromass Quattro II

triple quatrapole, Bruker LCT Premier ion-trap and Bruker Omni Flex

MALDI-TOF. Provided structure elucidation on small molecules and

peptides for customers

2. Wrote standard operating procedures on LC-MS instrument operations,

protein in solution digestion, protein in gel digestion, LC-MS/MS data

processing, and MASCOT database searching

3. Managed, fixed, and maintained LC-MS instruments

4. Trained graduate students on HP1100 LC, Shimadzu 10ADvp HPLC,

Micromass Quanttro II, and Bruker Omni Flex MALDI-TOF

5 Gained a lot of management experience when managing the mass facility.

Research Experience, Chemistry Department, Cleveland State University

(09/2000 to 12/2007)

1. Developed a novel ion exchange LC-MS/MS method for hydrophilic/polar

compounds, choline and arginine, in biological matrix using HP1100

LC- Micromass Quanttro II ESI-MS/MS, and confirmed that choline

level is elevated in myocardial necrosis patients. This work of

quantitation of small molecules in biofluids is similar to DMPK

study

2. Identified caspase 3 enzyme cleavage sites of recombinant membrane

protein cNHE1 using Bruker LCT Premier ion-trap MS/MS

3. Identified post-translational modifications of recombinant

glycoprotein Pigment Epithelium Derived Factor by LC-MS/MS and

identified glycosylation sites after trypsin digestion
