University of California

What you'll study

The programme covers foundational and advanced topics in how drugs interact with biological systems and how chemical exposures produce adverse effects. Teaching combines lectures, practical laboratory classes and an independent research project or thesis.

• Core topics: pharmacokinetics and pharmacodynamics, receptor theory, signal transduction, and dose–response relationships.
• Toxicology: mechanisms of toxicity, organ‑specific toxicology (hepatic, renal, neurotoxicology), genotoxicity, carcinogenesis and developmental/reproductive toxicology.
• Drug metabolism and biotransformation: phase I/II enzymes, transporters, metabolic pathways and interactions.
• Clinical and regulatory pharmacology: clinical trial design, therapeutic drug monitoring, drug safety assessment, risk evaluation and regulatory frameworks relevant to drug approval and chemical safety.
• Methods and techniques: in vitro and in vivo models, analytical chemistry methods (LC‑MS/MS), molecular biology techniques, tissue culture, toxicokinetic modelling and bioinformatics approaches for pharmacology/toxicology datasets.
• Quantitative skills: biostatistics, pharmacometrics and exposure assessment, with training in data analysis software commonly used in the field.
• Research project: an independent laboratory or translational research project under faculty supervision that may be oriented toward basic mechanisms, preclinical drug evaluation or applied toxicology.

Entry requirements

Applicants are expected to hold a recognised bachelor's degree in a relevant discipline such as biology, biochemistry, pharmacology, toxicology, chemistry, pharmacy or biomedical sciences. Typical application components include academic transcripts, a statement of purpose, two or more academic or professional references and a CV. Previous laboratory experience and coursework in molecular biology, physiology and quantitative methods are advantageous. Specific grade or GPA thresholds and any test requirements (such as the GRE) are set by the campus and should be confirmed on the programme’s admissions page.

Career prospects

Graduates enter a wide range of sectors where understanding drug action and safety is essential. Roles commonly pursued include:

• Pharmaceutical and biotechnology industry: drug discovery, preclinical development, pharmacokinetics/pharmacodynamics, safety assessment and clinical development support.
• Toxicology and environmental health: industrial toxicologist, product safety scientist, exposure assessment and risk assessment roles.
• Regulatory agencies and public health organisations: dossier preparation, regulatory affairs, safety review and policy advisory positions.
• Clinical and laboratory services: therapeutic drug monitoring, clinical research coordination and laboratory management.
• Scientific communication and industry support: medical writing, technical consultancy and scientific affairs.
• Academic research and further study: progression to PhD programmes or postdoctoral research in pharmacology, toxicology or related biomedical fields.

Why study at University of California

The University of California offers strong interdisciplinary training in pharmacology and toxicology, with access to medical centres, research hospitals and collaborations across life‑science departments. Faculty typically include basic scientists and clinician‑researchers working on translational problems from molecular mechanism to patient safety. Students benefit from modern laboratory facilities, opportunities for internships with biotechnology and pharmaceutical organisations in regional innovation clusters, and a research environment that emphasises both technical skills and regulatory‑relevant knowledge. The programme is well suited to those seeking a research grounding that is directly applicable to industry, regulatory and academic careers.
