Company: Arrowhead Pharmaceuticals

Job title: Associate Director of CMC Analytical Development


I completed my PhD from Louisiana State University A& M College in Biochemistry & Molecular Biology working on unique DNA binding properties of a histone-like protein from a highly radioresistant, dessication resistant organism, Deinococcus radiodurans. During my postdoctoral fellowship in Harvard Medical School, I worked on Bacteriophage T7 DNA replication understanding complex interactions of the DNA polymerase with the replication machinery during the different modes of replication; electrostatic mode and the polymerizing mode.
During my time at Pfizer Vaccines, I was involved in analytical characterization of different antigens, alone or in combination both in bacterial and viral vaccines that were in different phases of the development.
At Bristol Myers Squibb, I was mostly involved in development of late phase immuno-oncology projects, where we developed a phase-appropriate assessment of the quality attributes of drug substance and drug product. Thereafter, at Amicus Therapeutics, I led the Analytical team in biologics and gene therapy, developing unique assays for characterization and understanding the complexities of the drug development in my interaction with CMOs.
Currently at Arrowhead Pharmaceuticals, my team is involved in developing phase-appropriate analytical assays, HPLC, LC-MS and others, for the different synthetic oligonucleotides that knockdown the expression of target genes.
