PROFESSIONAL EXPERIENCE
Alcon Laboratories/Novartis - Fort Worth, TX 2003 - 2016
Project Lead – Safety Microbiology 2013 – 2016
•Provided microbiological compendial testing (United States Pharmacopeia and European Pharmacopeia) of pharmaceutical products (raw materials, in-process and final product) for project teams.
•Expertise in sterility testing, preservative effectiveness testing, bioburden, endotoxin, microbial limits and other compendial tests including validation.
•Developed and led pre-clinical in vivo studies for evaluation of topical antibiotic formulations. Outcome of studies resulted in project elevation and selection of a formulation for proof of concept (PoC) clinical studies. Preclinical data were presented to internal overnance bodies, key opinion leaders, and included in FDA submissions (Investigator’s Brochure [IB], FDA type B meeting and Investigational New Drug application [IND]).
•Supported clinical study teams by providing input into study design, manual of procedures (MOP), reviewed study reports, and reviewed and edited FDA submissions (IND and NDA).
•Supported project teams by responding to health authority questions regarding microbiological testing for product submissions and lifecycle management.
•Co-authored CMC quality sections (Module 3) of various CTD submissions to US, Europe, Asia and Latin America. Co-authored technology transfers, base documents and stability reports (based on ICH guidelines).
•Business development activites include: identified compounds for licencening and evaluated potential licencing opportunities from third parties.
Manager – Anti-Infectives 2009 – 2013
•Identified and evaluated finafloxacin for the treatment of external ear infections. Received FDA approval as XTORO (finafloxacin otic suspension, 0.3%) in December 2014 for the treatment of acute otitis externa (swimmer’s ear).
•Managed six research associates resulting in motivated and highly productive teams. Management duties included hiring, performance reviews, coaching, and terminations.
•Successful project team leader that advanced antibacterial and anti-viral compound selection to PoC clinical trials.
•Developed antibacterial in vitro screening protocols and novel in vivo models for evaluating topical antibiotics.
•Provided research support for project teams including contributing to pre-clinical pharmacology sections of FDA submissions (Investigator’s Brochure, IND, New Drug Applications [NDA] and technical reports).
•Established a testing laboratory from the ground up to identify efficacious antiviral compounds for the treatment of ocular infections.
Senior Scientist III – Anti Infectives 2007 – 2009
•Analyzed data that was included in FDA submissions for the successful approval of TOBRADEX ST (February 2009).
•Co-authored the pre-clinical pharmacology sections the IB, briefing packet and IND for a compound being developed to treatment bacterial and viral conjunctivitis.
•Developed genetic based and biological assays for the detection of Staphylococcus aureus toxins in support of Phase II clinical trials.
•Produced data for presentations (oral and posters) in support of Marketing (Phase IV) efforts.
Senior Scientist II – Anti-Infectives 2003 – 2007
•Bacterial identification and characterization by phenotypic and molecular methods (PCR, DNA sequencing and ribotyping).
•Conducted research studies for detection of tissue damaging bacterial toxins (PCR, ELISA, immunoblot and hemolytic assays).
•Authored technical reports describing in vitro and in vivo results of exploratory antibiotic studies.
