PK/PD Biostatistician

Description Project Need:

A new, accelerated funding deadline requires additional support for a Phase IV study, necessitating a "stopgap" hire.

Role Focus:

The position requires top-notch PK/PD skills for target attainment analysis, PopPK modeling, model refinement, and evaluation with biological interpretation.

Software Usage:

The team uses R for processing NONMEM output and iterating, with SAS for final summaries. Position Overview Seeking an experienced PK/PD Biostatistician Contractor to support a time sensitive, NIH funded Phase IV research program with a hard funding deadline. This role is a stop gap engagement to address an unexpected compression of end of study timelines, where current internal resources are insufficient to meet deliverables. The work supports a critically ill ICU patient population and focuses on advancing dosing recommendations for antibiotics in the setting of rapidly changing renal function. The project leverages a radiotracer based direct measurement of renal function, with the goal of evaluating and comparing GFR equations to inform dosing guidance and potential changes to clinical practice. ________________________________________ Contract Details

Contract Type:

Independent Contractor / Consultant

Expected Start:

June 1 (workload increases meaningfully at that point)

Duration:

Targeting up to ~6 months, with a hard funding stop on 11/30

Extension:

Possible short extension through year end for final processes and code archiving, but should not be assumed

Conversion:

Not expected ________________________________________ Project Scope & Responsibilities

• Lead and independently execute population PK modeling activities using NONMEM
• Refine and evaluate pre defined population PK models, including: o Covariate evaluation o Model refinement o Predictive performance comparison o Biological and clinical interpretation of results
• Perform PK simulations to support dosing evaluations and comparative analyses
• Support Phase IV analyses aimed at informing changes to dosing guidelines and clinical practice
• Collaborate internally with cross-functional teams supporting NIH funded research
• Utilize R extensively for model diagnostics, output processing, and iterative modeling decisions
• Interface with SAS programming support for final summaries and deliverables as needed
• Contribute to end of study deliverables, including analyses supporting CSR related outputs
• This role is primarily internal facing; minimal to no external client interaction expected

Additional Skills & Qualifications Candidate Profile:

They seek an independent model developer, ideally with a PhD and 3-5 years of experience, but a Master's with sufficient experience is acceptable. Required Skills & Experience Top Required Skills

• NONMEM (expert level; ability to efficiently build and manage control streams)

• Familiarity with critically ill or ICU populations
• Experience with renal function modeling or antibiotic PK (e.g., beta lactams) is a plus
• Exposure to CDISC / ADaM programming is a bonus but not required
• Prior experience on NIH funded or government sponsored research ________________________________________ Education
• PhD preferred with ~3-5 years of relevant post degree experience
• Master's level candidates considered if they demonstrate strong independent PK modeling capability Job Type & Location This is a Contract position based out of Rockville, MD.
