-
Foundations: Behavioral Health Literacy & AI Fundamentals
6 weeksGoals
- 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
Resources
- 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
MilestoneYou 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
-
Core Skills: Conversational Design & Safety Engineering
8 weeksGoals
- 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
Resources

-
Professional Portfolio: Capstone & Job Readiness
6 weeksGoals
- 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
Resources
- 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
MilestoneYou 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
BeginnerBuild 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.
RAG-Powered Psychoeducation Chatbot
IntermediateCreate 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.
Therapeutic Dialogue Fine-Tuning Pipeline
IntermediateFine-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.
Multi-Session Adaptive Therapy Program Simulator
AdvancedDesign 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.
Red-Teaming & Safety Audit Toolkit for Therapy AI
AdvancedBuild 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.
Mood Tracking NLP Pipeline with Wearable Integration
IntermediateBuild a system that analyzes free-text journal entries using NLP sentiment analysis and topic modeling, integrates heart rate variability data from a simulated wearable API, and generates personalized mood reports with AI-suggested coping strategies grounded in DBT skills.
