This monthly Sistership Circle is an invitation to step out of the busyness of everyday life and into a space of intentional connection. *** **Registration:** Please go directly to our Eventbrite page to register: [https://sistership-circle-may-2026.eventbrite.com](https://sistership-circle-may-2026.eventbrite.com) *** Whether this is your first time or you’ve joined before, you are warmly welcome. This is not a casual social meetup. It is a thoughtfully held space where you don’t have to perform, fix or hold everything together. *** **What to expect:** This is a guided, small-group experience that may include: • grounding and gentle breathwork • simple nervous system support practices • facilitated group conversation • time for reflection and integration ✨ We intentionally keep this gathering small (up to 12 women) to preserve the intimacy and quality of the experience. *** Women often leave feeling: • more grounded • more connected • more supported • and more themselves Each month offers a unique theme, while holding a consistent intention: to create a space where you can arrive as you are, exhale, and feel supported.

Healthcare organizations are increasingly using cloud-based real-world evidence (RWE) platforms to power clinical research, population health analytics, and AI-driven insights. However, building these systems on AWS introduces complex governance challenges around privacy, compliance, and multi-institution collaboration. This session explores how to architect data governance into healthcare analytics platforms on AWS, focusing on practical design patterns rather than policy theory. We examine how ethical data stewardship principles such as consent, accountability, and responsible data use, can be implemented using cloud-native controls and services. The presentation walks through key architectural considerations for secure RWE platforms on AWS, including role-based access control, auditability, data minimization, and encryption, and how these capabilities support compliance requirements such as HIPAA and GDPR. Attendees will learn how federated, multi-account AWS architectures enable collaboration across institutions while preserving local data ownership and control. We will also discuss privacy-preserving analytics patterns on AWS, including approaches that support federated learning, differential privacy, and secure computation to enable AI-driven insights without exposing raw patient data. Practical implementation trade-offs such as performance, scalability, and operational complexity will be highlighted using real-world platform scenarios. Attendees will leave with actionable AWS architecture patterns and governance strategies for building secure, compliant, and scalable real-world evidence platforms that unlock innovation while maintaining patient trust.

**ProductTank NoVA is back!** After a brief hiatus, we are relaunching the chapter with a format that cuts out the fluff and gets straight to the reality of building. Every product feed is flooded with AI hype right now, but what does it actually look like on the ground? Instead of a polished keynote, we are hosting **0 to 1 with AI: Real Product Talks**—a "Show & Tell" featuring 3–4 lightning talks focused on the intersection of AI and product. The framing for the talks is simple: *"Here is what I'm building, and here is what I'm stuck on."* We want to look at the messy, 0-to-1 reality of integrating AI into your workflows and products. *(Want to share what you are working on? Reach out! The bar is low-pressure, just 10–12 minutes to talk about a real AI problem you are trying to solve.)* **Agenda:** * **5:30 PM - 6:00 PM:** Doors open, networking, & name tags * **6:00 PM - 6:10 PM:** Welcome + Chapter Relaunch Intro * **6:10 PM - 7:30 PM:** Lightning Talks (Three 12-min talks + 5 mins Q&A each, with a 5-min stretch break) * **7:30 PM - 8:00 PM:** Open networking * **8:00 PM:** Soft close **Location & Logistics:** Herndon Fortnightly Library (Extended Hours Meeting Room) 768 Center St, Herndon, VA 20170 * **Parking:** We'll meet at the library, located just behind the Herndon Municipal Center. There is plenty of free public parking available around the municipal center. * **Metro & Bus:** Take the Silver Line to Herndon Metro Station, then connect via Fairfax Connector Route 921 or 950 to Historic Downtown Herndon. * **Driving (via VA-267/Dulles Toll Rd):** Take Exit 10 North (Centreville Rd, which becomes Elden St). Turn left onto Station St or Lynn St. * **Driving (via VA-286/Fairfax Co Pkwy):** Take the Elden St West exit.
