Teh Director/Sr Director, Injection Physiology & Parenteral Delivery Science leads and directs the group's injection physiology and parenteral delivery science team — the scientists and engineers who quantify how injection parameters (flow rate, volume, viscosity, needle geometry, and injection depth) govern local tissue response, injection-site reactions, drug distribution, and systemic exposure across subcutaneous, intradermal, and intramuscular routes, and who build the ex-vivo tissue models, imaging, rheology, and biofluid-dynamics/CFD workflows that enable higher-concentration and higher-volume delivery. We are seeking a hands-on, senior technical leader to set scientific direction for this portfolio while leading, coaching, and developing a team of junior scientists — providing day-to-day technical guidance, prioritization, and mentorship — and operating at the enterprise level: representing Lilly externally with academic, clinical, and regulatory stakeholders and translating injection-physiology understanding into device-design, formulation, and dose-selection decisions across the pipeline.
