The Convergence Engine for Drug Development

I turn therapeutic ideas into clinical programs via the shortest defensible and fundable path. I step into the next constraint facing a company. I've owned both ends of the development path: discovery through FIH, and Phase 3 to global approval. That range is why the early decisions are defensible — I know what the plan has to survive.

My role is to connect the decisions that are often made in isolation, biologics discovery and engineering, preclinical, translational, CMC, regulatory and capital strategy and turn them into a coherent, executable development plan.

I operate across Advisory, Consulting and Fractional embedded leadership, afforded by a career arc over two and a half decades working within large-scale matrix leadership to hands-on R&D Operations integration

NewCos Incubated (Seed to IND track, founder equity in both)
20+
IND-ready Programs Led across multiple therapeutic areas
Over two and a half decades, the thread has been integration. I've incubated two NewCos from seed capitalization to IND track on de novo highly engineered Fc/HLE bi-specific antibodies, holding founder equity on both. At Paragon I led preclinical development and that foundation carries Spyre, Oruka and Jade to the clinic with potentially best-in-class data. At Deciphera I led TechOps program and alliance management through Qinlock's approval, including a first-of-its-kind concurrent authorization under FDA's Project Orbis. And I led the CMC team for Romvimza from discovery to clinical development. At J&J I integrated 20+ global CMC programs across biologics and small molecules.

Most often lean teams don't fail on science. They fail on sequencing, and on discovering too late what the plan assumed. I own decisions and timelines, and give a non-diluted view of the risks, costed out at each inflection point. Accelerate with intent on first principles; hold steady when risk overruns enthusiasm.

Integration Architecture

Multiple scientific disciplines converge into a single executable focal point.

NODE_01

Asset discovery & Optimization

Multi-specific biologics and small molecules engineered for developability. Guiding discovery principles to enable efficient progression through preclinical and clinical development

NODE_02

CMC Strategy

Integrated CMC development workplan encompassing from small scale to GMP production. CDMO selection & partnership, process development, analytical methods, regulatory CMC documentation

NODE_03

Preclinical Execution

IND-enabling studies to FIH-readiness as a unified deliverable designed with manufacturing constraints. Incorporating DMPK, toxicology, translational expertise as appropriate

NODE_04

Regulatory Pathway

FDA/EMA strategy, IND preparation, breakthrough designation pursuit. Cross-functional team leadership toward submission milestones

IND-Ready Asset

Fully integrated development package positioned for clinical entry and Series A fundraising

Strategic Engagement Models

[01]

NewCo Incubation

Corporate structure design using the Roivant/Paragon blueprint for optimized Seed and Series A fundraising pathways.

  • C-suite coaching and development team assembly
  • Investor presentation and data room preparation
  • Capital-efficient operating model design
  • Strategic milestone planning (Seed → Series A → IND)
[02]

Integrated CMC & Preclinical Development

Unified workplan from developability assessment through IND submission, where CMC and preclinical strategies inform each other.

  • CMC roadmap: Bridging lead-op/discovery to developability, cell line development to formulation/process development to GMP manufacturing for FIH and beyond
  • IND-enabling study design (translational, disease animal models, DMPK, tox)
  • Strategic CDMO/CRO MSA-governed agreements
  • FIH-readiness as integrated deliverable
[03]

R&D Operations & Program Leadership

Cross-functional team integration and program management infrastructure for lean, capital-efficient biotech operations

  • Global program matrix team leadership
  • Regulatory pathway strategy (FDA, EMA)
  • Alliance and partnership management
  • Budget management and resource allocation
  • Risk mitigation and contingency planning

Execution History

2024 – early 2026

2x NewCo, Inc. Stealth (Immunology & Inflammation)

Incubated and launched two (2) NewCos targeting atopic diseases with de-novo multi-specific HLE-extended and Fc-engineered antibodies. Coached investment team in end-to-end corporate design, equity structure and integrated R&D Operations functions. Spearheaded CMC workplan to FIH readiness and translational/tox IND-enabling studies. Major MSA-governed partnerships with leading CDMOs were established (Adimab, ChemPartner, WuxiBio, PharmaLegacy, WuxiAppTec, Charles River).

Founder equity in both
$6M seed each
2026/27 IND submissions
Series A positioned
2023 – 2024

Paragon Therapeutics

Head of Preclinical Development

Reporting to the Chief Operating Officer, responsible for strategic and operational leadership for preclinical development across an extensive portfolio of best-in-class biologics. Led integration of all preclinical IND-enabling studies to a CMC accelerated workplan for three spin-offs, now in clinical development with robust and potentially best-in-class data, each backed by initial $200M+ private placements.

Spyre (IBD): ~$200M Series A
Oruka (Psoriasis): $200M+ Series A
Jade (Nephrology/I-O): ~$200M Series A
2022 – 2023

Seeker Biologics, a 5AM Ventures Company

Head of Program Leadership

Reporting to the Chief Scientific Officer, led the program management function across the portfolio of innovative de novo discovered multi-specific biologics (scFv, VHH) with minimized cytotoxicity and increased selectivity to address significant medical need primarily in immune-mediated diseases and oncology
