The next stage of the case is oral arguments in DC Court of Appeals, come to support Roman and the future of Bitcoin ownership in US. Roman has been convicted by of allegedly operating BitcoinFog, a mixing service accused of anonymizing Bitcoin transactions, a small portion of which is thought to be attributable to illicit usage. The charges identify no victims or financial loss and instead attribute to him any potential crimes of anybody on the internet who was using this privacy tool.

**The Kosciuszko Foundation Next-Gen Association for Young Professionals** invites all peers in the Washington, DC and surrounding areas to the event: ***Scaling Success: Poland’s Private Sector in the Global Economy. Panel with Erik Brattberg and Pablo Rasmussen, Brzezinski Global Strategies.*** Join us for a dynamic KF Next-Gen panel discussion and networking reception featuring Erik Brattberg and Pablo Rasmussen of Brzezinski Global Strategies. Together, we will explore the key drivers behind Poland’s private sector expansion, including entrepreneurship, foreign investment, and regulatory evolution, while examining emerging opportunities in clean energy, digital innovation, and infrastructure, as well as the challenges ahead. **TUESDAY\, May 12\, 2026 \| 6:00\-8:00 PM** **The Kosciuszko Foundation DC** 2025 O Street NW Washington, DC 20036 **Poland has emerged as one of Europe’s most dynamic economic success stories**, with its private sector playing a central role in driving sustained growth and innovation. Over the past three decades, the country has transformed into a leading economy in Central and Eastern Europe, with rapid GDP expansion and notable resilience through global economic shocks. Today, Poland ranks among the largest economies in the European Union, supported by a diversified industrial base and a highly skilled workforce. At the heart of this transformation is a vibrant and expanding private sector. Market-oriented reforms have enabled private enterprises to account for roughly 80% of employment, exports, and economic value creation—making them the primary engine of national growth. From advanced manufacturing and logistics to a fast-growing technology and services ecosystem, Polish firms are increasingly competitive on the global stage. **Erik Brattberg** is Managing Partner of Brzezinski Global Strategies. He previously served as Senior Vice President at DGA-Albright Stonebridge Group, advising clients on U.S. national security policy, transatlantic relations, and political risk. A recognized expert on Europe with over 15 years of experience, he has held senior roles at the Carnegie Endowment for International Peace and the McCain Institute, among others.

Join us for a journey to Sri Lanka to see the unique habitats and species that call this island nation home. Over 40% of Sri Lanka’s native vertebrate species are found nowhere else and bird species diversity tops 240. This presentation will showcase some of the great variety of habitats, birds, mammals, reptiles, amphibians, and insects that we saw while enjoying delicious food and interesting cultural features. George Jett and Gwen Brewer have led Maryland field trips and presented talks on their travels together for bird clubs for over 20 years. Gwen manages the science program for rare species at the Maryland Department of Natural Resources and previously was a professor at Frostburg State University. George is retired from the Environmental Protection Agency and is an avid nature photographer- check out his photos at [georgejett.net](http://georgejett.net/). When not looking for birds, mammals, and herps in far-off places, they enjoy birding and kayaking from their property near Jug Bay in southern Anne Arundel County. Door opens at 7:00 for informal talk. Program starts at 7:30. Light refreshments will be provided. This event is free and open to the public.

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.
