What jobs do behavioral scientists do?

Behavioral scientists study human behavior to develop insights that can improve decision-making, policies, and interventions. They often work in research, healthcare, public policy, or corporate settings, using data analysis and experimental methods to understand and influence behavior. Their work may involve designing programs, conducting experiments, and applying psychological theories to real-world problems.

What are behavior scientists?

Behavior scientists are professionals who study how people and animals behave, often focusing on the underlying psychological, social, and environmental factors that influence actions and decisions. They use research methods and data analysis to understand patterns in behavior and develop strategies to encourage positive changes. Behavior scientists work in various settings such as healthcare, education, business, and government, contributing to programs and policies that improve individual and societal outcomes.

What can you do with a behavior science degree?

A behavior scientist can work in areas such as research, program development, and intervention design to analyze and modify human behavior. They often work in healthcare, education, or corporate settings, utilizing data analysis, behavioral theories, and evidence-based strategies. Roles may require skills in data collection, statistical tools, and understanding of psychological principles.

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

To thrive as a Behavior Scientist, you need a solid background in psychology, behavioral analysis, and research methods, usually supported by an advanced degree in a relevant field. Familiarity with statistical software (e.g., SPSS, R), data collection platforms, and IRB protocols is typically required. Strong analytical thinking, communication, and collaboration skills distinguish top performers in this role. These skills enable accurate study design, insightful data interpretation, and effective application of findings to influence behavior and inform policy.

What can I do with behavioral science?

A behavior scientist applies principles of psychology and data analysis to understand and influence human behavior. They work in areas such as healthcare, marketing, public policy, and organizational development, often using research methods, statistical tools, and behavioral theories to develop interventions and solutions.

What are some of the main challenges Behavior Scientists face when working with multidisciplinary teams?

Behavior Scientists often collaborate with professionals from fields like data science, design, public health, and engineering. A common challenge is effectively communicating complex behavioral theories and research findings to team members with different backgrounds. Bridging these knowledge gaps requires strong interpersonal skills and the ability to translate scientific concepts into actionable strategies. Additionally, aligning behavioral interventions with broader project goals and timelines can be demanding but also offers valuable opportunities for professional growth and impact.

What is a behavioral scientist?

A behavioral scientist studies human and animal behavior to understand why people act in certain ways. They often use research methods, data analysis, and psychological theories to develop interventions or policies that influence behavior, frequently working in research, healthcare, or public policy settings.

Job description

At Toyota Research Institute (TRI), we're on a mission to improve the quality of human life. We're developing new tools and capabilities to amplify the human experience. To lead this transformative shift in mobility, we've built a world-class team advancing the state of the art in AI, robotics, driving, and material sciences.


The Team 
 
TRI's Adaptive Behavior Systems Department within our Human-Centered AI (HCAI) Division aims to develop AI systems that can support behavior change, such as reducing carbon emissions. To do this, we are developing novel models of human behavior that integrate behavioral science, Human-Computer Interaction, and advanced machine learning.
 
The Opportunity
 
We are looking for an AI Research Scientist or Senior AI Scientist with expertise in large-scale foundational model training, fine-tuning, evaluation, and benchmarking. This role operates at the forefront of generative machine learning and human behavior modeling. Ideal candidates will bring a strong research track record, hands-on experimentation skills, and experience developing and deploying foundational models. This role sits at the intersection of social science and generative AI, building models that represent human beliefs, preferences, and cognition as they change over time. For an example of our early research in this vein, please see https://arxiv.org/abs/2403.20252.
Responsibilities
  • Conduct machine learning research that integrates behavioral science concepts to push the boundaries of knowledge and the state of the art in Human-Centered AI.
  • Develop and evaluate generative AI and machine learning methods for modeling and understanding human behavior.
  • Collaborate cross-functionally with researchers in multiple fields, as well as university partners.
  • Stay up to date on the state-of-the-art in machine learning theories, methods and tooling.
  • Collaborate with scientists in the Adaptive Behavioral Systems Department to shape our research program and to communicate research to Toyota stakeholders.
  • Publish research findings in academic journals and/or conferences.
  • Contribute to technology transfer of research insights and prototypes throughout Toyota.
Qualifications
  • PhD in computer science, machine learning, or a closely related field with 1-7 years of experience in machine learning research or related projects in an industry setting, particularly in areas related to LLM training or large-scale ML. Industry experience is a plus. 
  • A strong publication record in ML, NLP, deep learning, or related fields.
  • Awareness of current machine learning research and the ability to critically evaluate emerging techniques and literature.
  • Experience with LLM/MLLM pretraining, fine-tuning (e.g., SFT, RLHF) and agentic systems.
  • Proficiency in  Python and modern deep learning frameworks such as Pytorch or Tensorflow
  • Ability to work collaboratively across disciplines and functions.
  • Ability to balance multiple projects, including short-term and those that may span several years.
  • Strong project management skills and desire to work on cutting-edge open-ended research projects.
  • Demonstrated ability to independently identify research opportunities, formulate well-scoped problems, and lead research projects end-to-end.
  • Demonstrated ability to work autonomously while soliciting feedback.
  • Strong interpersonal skills. Great teammate.
Bonus Qualifications
  • Experience with one or more of the following areas: diffusion models, uncertainty modeling, reinforcement learning, and physiological signal processing.
  • Previous experience in human modeling (both cognitive and behavioral) with generative AI.
  • Experience with human-centered research (e.g. computational behavioral and social science, human-computer interaction, neuro-science).
Please add a link to Google Scholar to include a full list of publications when submitting your CV for this position.
 
The pay range for this position at commencement of employment is expected to be between $176,000 and $253,500/year for California-based roles. Base pay offered will depend on multiple individualized factors, including, but not limited to, a candidate's experience, skills, job-related knowledge, and market location. TRI offers a generous benefits package including medical, dental, and vision insurance, 401(k) eligibility, paid time off benefits (including vacation, sick time, and parental leave), and an annual cash bonus structure. Additional details regarding these benefit plans will be provided if an employee receives an offer of employment.
