What is a bioassay?

A bioassay is a scientific procedure that uses living organisms, cells, or tissues to measure the potency or concentration of a substance, such as a drug, hormone, or chemical compound. Bioassays help determine the biological activity of a substance by observing its effects on the test system. These assays are crucial in pharmaceutical development, environmental monitoring, and quality control to ensure safety and efficacy.

What are the key skills and qualifications needed to thrive as a bioassay scientist, and why are they important?

To thrive as a Bioassay Scientist, you need a solid background in biology, chemistry, or related sciences, often supported by at least a bachelor's or master's degree. Familiarity with laboratory equipment, data analysis software (like GraphPad Prism), and regulatory standards such as GLP is typically required. Attention to detail, problem-solving abilities, and effective teamwork are crucial soft skills in this field. These skills and qualifications are essential to ensure accurate, reliable biological data and compliance with industry standards in drug development and quality control.

What are some common challenges faced by professionals working in bioassay roles, and how can they be addressed?

One of the main challenges in bioassay roles is ensuring the accuracy and reproducibility of experimental results, as biological systems can be inherently variable. Professionals often need to meticulously optimize assay conditions and maintain strict quality control to minimize variability. Additionally, interpreting complex biological data and troubleshooting unexpected results are frequent aspects of the job. Collaborating closely with cross-functional teams, such as analytical chemists and quality assurance specialists, helps address these challenges and ensures reliable outcomes.

What is the difference between Bioassay vs Laboratory Technician?

AspectBioassayLaboratory Technician
Required CredentialsTypically requires a degree in biology, biochemistry, or related fields; certifications may enhance prospectsUsually requires a high school diploma or associate degree; technical certifications are common
Work EnvironmentConducted mainly in research labs, pharmaceutical companies, or biotech firmsWorks in various lab settings, hospitals, or manufacturing facilities
Industry UsagePrimarily in biotech, pharmaceuticals, and research institutionsWidely used across healthcare, manufacturing, and research sectors

Bioassay professionals focus on testing biological activity of substances, often involving complex experiments and data analysis. Laboratory Technicians perform routine lab tasks, sample preparation, and equipment maintenance. While both roles require laboratory skills, bioassay roles tend to involve more specialized testing and analysis, whereas lab technicians support general lab operations.

Job description

Overview

The Human Sleep Research Program within SRI's Center for Health Sciences conducts multidisciplinary research to better understand sleep and its relationship with health and behavior. Our work spans a variety of research areas, including wearable technologies for measuring sleep and physiology, sleep deprivation, women's health, neuropsychology, and neuroimaging.

This internship offers the opportunity to contribute to multiple human research studies and gain hands-on exposure to a wide range of research methods and technologies. Our studies collect rich, multimodal data including overnight EEG recordings, wearable-derived biosignals such as physical activity and heart rate, cognitive and neuropsychological assessments, clinical and self-report measures, bioassays, and multimodal MRI.  Interns will work alongside an interdisciplinary research team and gain practical experience across different stages of clinical and translational sleep research. The position is particularly well suited for someone interested in gaining broad research experience while contributing to studies with applications to human health and emerging health technologies.

The internship will be on-site in our Menlo Park, CA office.  This is a part-time year round role, 10-20 hours per week.  Candidates must be able to work overnight shifts.

Responsibilities
  • Support multiple human sleep research studies conducted within the Human Sleep Research Program.
  • Assist with participant-facing research visits, including overnight, evening, afternoon, and early-morning study procedures.
  • Ability to remain awake, alert, and attentive throughout overnight research shifts.
  • Assist with collection of physiological and behavioral research data, including overnight EEG/sleep recordings, wearable device data, cognitive and neuropsychological assessments, self-report and clinical measures, and bioassays.
  • Support collection of multimodal MRI data and other study-specific procedures as needed.
  • Assist with research data entry, organization, quality control, and preparation for analysis.
  • Contribute to data analysis and visualization projects, potentially including analyses of wearable, sleep, cognitive, physiological, and neuroimaging data.
  • Follow study protocols and research procedures to ensure accurate, consistent, and high-quality data collection.
  • Work collaboratively with research staff across multiple projects and assist with other research activities as needed.
Qualifications
  • Current Bachelors/Masters/PhD student in psychology, neuroscience, biology, cognitive science, or a related field.
  • Candidates must be a US Citizen
  • Interest in sleep research a plus
  • Detail-oriented and good organizational skills are highly desired

The salary range is: $17.55-$23/hr. Salary ranges will vary and are based on several factors, including geographic location, market competitiveness and equity amongst internal employees in similar roles. Positions may also qualify for SRI's Pay for Outstanding Performance program or the annual Performance Based Compensation program.
