  1. Foundations: Behavioral Health Literacy & AI Fundamentals

    6 weeks
    • Understand core therapeutic frameworks (CBT, DBT, ACT, MI) and their structured session flows
    • Learn the architecture of modern LLMs, prompt engineering basics, and API integration
    • Grasp the regulatory landscape - HIPAA, GDPR, FDA digital therapeutics guidance - as it applies to AI health apps
    • Coursera: 'Introduction to Psychology' by Yale (Paul Bloom)
    • OpenAI Cookbook and API documentation
    • Book: 'The AI Clinician' by Jenna Lester (Harvard Digital Health Review)
    • NIMH Digital Therapeutics Research Portfolio (free PDFs)
    • LangChain documentation: Getting Started tutorial
    Milestone

    You can decompose a simple 3-session CBT module into a conversational flow diagram and build a basic chatbot prototype using OpenAI API with safety guardrails

  2. Core Skills: Conversational Design & Safety Engineering

    8 weeks
    • Master multi-turn conversation architecture including intent classification, slot filling, and context memory management
    • Build crisis detection and escalation pipelines using sentiment analysis and keyword + ML hybrid approaches
    • Implement RAG pipelines grounded in clinical knowledge bases with proper citation and hallucination controls
    • Book: 'Conversational AI' by Andrew Freed (O'Reilly)
    • Rasa Open Source documentation and tutorial series
    • LangChain RAG tutorial and vector store documentation
    • Paper: 'Ethics and governance of AI in mental health' (Nature Digital Medicine, 2023)
    • Weights & Biases 'Building LLM-Powered Apps' course
    Milestone

    You can build a clinically-informed chatbot with RAG grounding, crisis escalation logic, and basic analytics - deployable as a Streamlit prototype with real conversation flows

  3. Applied Practice: Fine-Tuning, Evaluation & Regulatory Awareness

    8 weeks
    • Fine-tune an open-source LLM on therapeutic dialogue data using Hugging Face and W&B for experiment tracking
    • Design and implement clinical fidelity evaluation rubrics and automated safety testing suites
    • Understand the FDA Pre-Cert program, CE marking pathway, and evidence requirements for digital therapeutics
    • Hugging Face NLP Course (free)
    • FDA guidance: 'Clinical Decision Support Software' and 'Digital Health Technologies'
    • Paper: 'Evaluating the Safety of Mental Health Chatbots' (JMIR Mental Health)
    • W&B fine-tuning reports and sweep documentation
    • Label Studio documentation for therapeutic dialogue annotation
    Milestone

    You can fine-tune a therapeutic chatbot model, run systematic safety and fidelity evaluations, and draft clinical documentation suitable for regulatory review

  4. Professional Portfolio: Capstone & Job Readiness

    6 weeks
    • Build a complete, production-quality behavioral health AI app feature end-to-end
    • Create a case study with clinical rationale, design decisions, safety analysis, and measured outcomes
    • Develop a professional network through digital therapeutics conferences, research communities, and open-source contributions
    • Digital Therapeutics Alliance (DTA) member resources and annual summit
    • GitHub: Contribute to open-source mental health AI projects
    • Blog platform (Medium/Substack) for publishing case studies
    • LinkedIn: DTx, HealthTech, and AI Mental Health communities
    • Mock interview platforms and clinical scenario simulation tools
    Milestone

    You have a polished portfolio with 2-3 shipped prototypes, a published case study, clinical advisor testimonials, and a network that positions you for roles at DTx companies, health systems, or AI health startups

Practice Projects

Apply your skills with hands-on projects. Ordered by difficulty.

CBT Chatbot MVP with Safety Escalation

Beginner

Build a conversational AI chatbot that guides a user through a single CBT thought record exercise - identifying a negative thought, examining evidence, and reframing - with built-in keyword-based crisis detection that triggers an empathetic escalation response and provides crisis hotline information.

~25h
Prompt engineeringCBT protocol decompositionCrisis detection logic

RAG-Powered Psychoeducation Chatbot

Intermediate

Create a chatbot that answers user questions about anxiety and depression by retrieving information from a curated knowledge base of clinical guidelines (e.g., NICE, APA) using LangChain RAG, with source citations, hallucination guards, and a clinician review dashboard built in Streamlit.

~40h
RAG pipeline designClinical content curationHallucination mitigation

Therapeutic Dialogue Fine-Tuning Pipeline

Intermediate

Fine-tune an open-source model (e.g., Mistral-7B) on a curated dataset of therapeutic conversations using Hugging Face TRL, with Weights & Biases tracking for clinical fidelity metrics, empathy scores, and safety violation rates across training epochs.

~50h
Model fine-tuningTherapeutic data annotationExperiment tracking

Multi-Session Adaptive Therapy Program Simulator

Advanced

Design and prototype a 6-session adaptive therapy program where the AI adjusts intervention complexity and focus areas based on user-reported outcomes and conversation analysis, with session memory management, clinician review portal, and simulated user testing framework.

~70h
Adaptive system designSession memory architectureClinical outcome tracking

Red-Teaming & Safety Audit Toolkit for Therapy AI

Advanced

Build a systematic safety testing toolkit that generates adversarial test cases for therapy chatbots - including crisis language variations, jailbreak attempts, culturally diverse expressions of distress, and edge-case clinical scenarios - with automated scoring and reporting dashboards.

~60h
