Summary of Expertise: Listed with other top experts in: 
Expert, is an independent consultant with 15+ years experience in developing controlled release implantable and injectable products for proteins/peptides and small molecule drugs, spanning from chronic/systemic delivery to acute/local delivery, with special focus on drug delivery platforms and drug-device combination products. Expert has worked previously in both large (Fortune 100) and small company setting. My expertise is to drive, lead and streamline advancement of convergent medical technologies, from feasibility to clinical testing to commercialization, within a sound scientific and regulatory framework to address unmet medical needs.

"Chemistry, Manufacturing and Controls", CMC in short, is a key module in a regulatory submission that includes all key development information demonstrating proper identity, strength, quality, and purity of the medical product seeking regulatory approval. One of my consulting services is to advise clients to achieve "CMC Right the First Time". It is of utmost importance to adopt this philosophy from concept to launch to minimize unnecessary reloops and maximize probability of technical/regulatory success for any projects. Especially with the tighter timelines of developing drug-eluting devices, flawless CMC executions, together with excellent communications with diverse cross-functional experts, including device engineers, are crucial to successful product advancement and launch.

Expert is a passionate leader with strong diverse interdisciplinary knowledge with a number of key skill sets:

1. Broad Product R&D Experience on Complex Products — over 12 years experience (16+ years in life science) in early and late stage development of drug delivery and drug-device combination products (proteins to small molecules); overcome numerous complex drug-device interface issues; served as technical counsel to executive management in assessment of technology licensing and IP base; drove team to full compliance with ICH, USP/EP/JP, cGMP, ISO, AAMI and Design Control guidelines

2. Rapid Innovation from Concept Definition through Tech Transfer — drive concepts from feasibility to commercialization rapidly by incorporating sound scientific/regulatory approaches to minimize unnecessary re-loops and cost creep (Conor); led multiple successful troubleshooting teams to resolve product issues during development and post launch, leading to substantial monetary savings

3. Strong Drug Delivery Expertise — extensive development experience with drug-device implantable products for systemic and local drug delivery; acted as Technology Leader to emerging technology platforms; led team to develop novel, stable, and highly concentrated self-injectable mAb formulations for non-IV use (ALZA/J&J); excelled in unbiased technology assessment with focus on user/patient needs

4. Expand Versatility of Drug Delivery Platforms — advanced drug-eluting stent platform to new vascular indications with input from key opinion leaders (Conor); expanded intellectual property base for emerging technology platforms (ALZA/Conor); identified candidate drugs to explore new product concepts with platform technologies; acted as major liaison to strategize delivery needs for mAb (ALZA/Centocor)

5. Proven Track Record in Team Leadership and Project Management — Led multiple product and platform development teams to meet timelines and budget; acted as point liaison and led collaborations with external companies; supervised focused R&D teams and provided strong mentoring for direct reports to enhance staff engagement, innovativeness and organizational success
