I am a Senior-level Associate Scientist and certified Molecular Biologist MB (ASCP) with more than 10 years’ experience in biotechnology/ pharmaceutical environments. I have been with Amgen Oncology Biomarker group since 2008. I am looking for advancing my career and exploring new opportunities with start-up to mid size organization . I have experience in assay development and validation, cell based assay, protein purification and characterization, stable cell lines propagation, DNA/ RNA extraction and quantitation. In general i am passionate about science and serving patients. I have the ability to wear multiple hats and adapt to changes rabidly. I am very driven, and self-motivated to deliver quality data can be trusted. In addition to my scientific expertise, I have proven capabilities in writing detailed research reports with statistical analysis and recommendations. I am self-motivated professional who works independently and also collaborates with teams. Articulate communicator with all organizational levels.
