Job Description

Position Summary

Postdoctoral Scholar

Hormone Homeostasis, Drug Metabolism, and Women's Health

Michigan State University

Department of Pharmacology & Toxicology

Department of Biomedical Engineering

The laboratory of Dr. Brian P. Johnson at Michigan State University invites applications for a Postdoctoral Scholar to join a multidisciplinary research team investigating how female hormonal state influences the metabolism, efficacy, and safety of medicines throughout the body.

This position is supported by the NIH Computational Modeling of Hormone Homeostasis initiative and will focus on generating experimental data needed to understand how changing endocrine states alter tissue-specific drug responses in women. The successful candidate will work closely with a collaborative team of endocrinologists, toxicologists, engineers, and computational scientists, while leading experimental studies at the interface of women's health, drug metabolism, and endocrine biology.

Research Overview

Women experience significant physiological changes across the menstrual cycle, pregnancy, menopause, and endocrine disorders such as polycystic ovary syndrome (PCOS). These hormonal changes can alter the way medicines are metabolized and how tissues respond to therapeutic interventions. However, the biological mechanisms underlying these differences remain poorly understood.

The successful candidate will help develop human-relevant experimental models to determine how endocrine state influences drug metabolism and tissue-specific responses, with particular emphasis on:

• Thyroid hormone signaling and homeostasis
• Adipose tissue metabolism and energy balance
• Interactions between reproductive hormones and drug metabolism pathways
• Human cell-based and microphysiological systems
• Tissue-specific responses to pharmaceutical compounds under different hormonal conditions
• Generation of quantitative experimental data to support predictive models of drug efficacy and safety in women

Research in the Johnson Laboratory aims to improve our understanding of how hormonal state impacts medicine response across a woman's life course and ultimately support the development of more precise and effective therapeutics. [Johnson Models Aim 4 | Word], [Project Su...9-2026_EOV | Word]

• Contribute experimental data and biological insight to a large interdisciplinary research effort
• Collaborate with investigators across endocrinology, toxicology, engineering, and computational modeling disciplines
• Publish findings in peer-reviewed journals
• Present research at national and international scientific meetings
• Mentor graduate and undergraduate trainees

Required Qualifications
