[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Psychedelic-Assisted Therapy,”** on findings, debates and trends in the use of psychedelic substances to treat trauma and other conditions, with Whitney Marris, instructor at the University of Buffalo’s School of Social Work, certified psychedelic-assisted therapy facilitator, and consultant to clinical trials. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-psychedelic-assisted-therapy](https://events.ticketleap.com/tickets/profsandpints/dc-psychedelic-assisted-therapy) .] Psychedelics are rapidly moving from the margins into the mainstream, and questions abound as the sociocultural and legal landscapes surrounding them shift. President Trump’s recent executive order expanding access to psychedelic drugs for certain conditions and accelerating research on them has both heightened interest and added to confusion. Learn more about the so-called “Psychedelic Renaissance,” and get help separating the hope from the hype surrounding it, with Whitney Marris, a leading trainer and facilitator of psychedelic therapy who has used it to treat trauma survivors, military veterans, and people with cancer. She’ll present foundational information on what we know about how psychedelics work. You’ll learn how psychedelic-assisted therapy differs from “trip sitting” and about what we know about the effects of “microdosing” versus “macrodosing.” We’ll examine what has been demonstrated to be helpful versus harmful before, during, and after a dosing session intended to support significant, sustainable change. Marris also will discuss the historical and cultural context of the use of psychedelic medicines for healing, and she’ll describe the ethical challenges that arise as such practices move from counterculture to clinic. We’ll look at emerging and evolving findings in the field, as well as at the roles being played by various financial interests and ideologies in determining the direction of psychedelic-assisted therapy and research on its outcomes. Attendees will gain an awareness of the need for new professional standards and regulatory guardrails related to such work, and they’ll leave knowing key questions to ask potential providers of psychedelic-assisted therapy.

Very few books are absolute must-reads. This is one.”―Siddhartha Mukherjee, assistant professor of medicine at Columbia University and author of The Gene: An Intimate History "During the 25 years I have known Jamie Metzl, he has always been ahead of the curve. There is no one better to help us understand and prepare for the fast-approaching technological revolutions. Superconvergence is brilliant. I can't recommend it more strongly."―Sanjay Gupta MD, bestseller author, neurosurgeon, and Emmy-award winning chief medical correspondent (CNN) "Our world is defined by our science and technology—whether we like it or not. The question now is not whether to use these powers, but how best to use them. In Superconvergence, Jamie Metzl takes us on a journey through the new capabilities that are radically transforming ecosystems inside us and around us, challenging each of us to get personally involved with building the future we want."―Beth Shapiro, University of California Santa Cruz evolutionary biologist and author of Life as We Made It: How 50,000 Years of Human Innovation Refined―and Redefined―Nature "In a fine counter-blast to the pessimism of today, Jamie Metzl lays out just how spectacular the future of humanity and planet can be if we harness innovation responsibly and imaginatively to create what he calls the 'spiral of progress.'"―Matt Ridley, author of How Innovation Works, and co-author of Viral: The search for the Origin of Covid-19 “A page-turning journey through space and time that shows us how our lives will be changed by imminent technological advances we once only dreamed of.”―David Sinclair, Professor of Genetics, Harvard Medical School, and author of Lifespan: Why We Age―and Why We Don't Have To “The superconvergence of the genetics, biotechnology, and AI revolutions provides spectacular opportunities for building a better world. It also represents an almost limitless investment opportunity. We were excited to collaborate with Jamie Metzl, one of the world's great experts on how these aspirations can best be realized, including in capital markets. Superconvergence is a master class for imagining, investing in, and building a future we'd like to inhabit."―Jeremy Schwartz, Global Chief Investment Officer, WisdomTree “A clear examination of a transitional moment in the story of life on Earth…. Metzl capably describes recent developments in genetics and biotech and looks at how AI is providing an analytical engine of unprecedented power…. An important book in which the author sets out a path for the future based on his experience and expertise.”―Kirkus “Erudite, optimistic, and timely.”―Science Magazine "[In Superconvergence] Mr. Metzl has identified an important truth: that the convergence of new technologies is galvanizing us to reimagine how to meet urgent challenges in medicine and the environment. It’s a compelling opportunity—provided we manage to sidestep self-induced catastrophes along the way."―The Wall Street Journal ### About the Author Jamie Metzl is a leading technology and healthcare futurist and the founder and chair of OneShared.World.

**The next GeoDC will be held on Wednesday, June 10 from 6-9pm at Sudhouse DC (1340 U St NW, Washington, DC 20009) with the program starting at 7pm.** * Join us early from 6-7pm to grow your network, socialize and grab drinks and appetizers. * Throughout the evening, we'll be sharing job announcements and details of other GIS/Geo upcoming events we're tracking. * We look forward to seeing you on the 10th! **Our Program will feature these presentations:** **The Secret History of the Blue Dot - William H. Tewelow, GISP (GPS World)** This presentation takes the audience from an iconic movie scene they recognize but never understood, through the hidden origins of GPS, and returns them to the blue dot in their own hand, seeing it for the very first time. There is a blue dot on your phone right now. It knows where you are to within a few feet. You have never questioned it. You have never wondered where it came from. You should. Its origins are classified. Its lineage runs through the Cold War, nuclear submarines, and a doctrine built on the promise of mutual annihilation. The technology that tells you where to turn was designed for something else entirely. The technology did not change. Only the purpose did. **GEOINT Symposium's Golden Ticket Program - Katie Weintraub (ESRI)** This is a firsthand account of USGIF's GEOINT Symposium Golden Ticket — a program built for early-career professionals who want to level up their careers. Participants get free admission to GEOINT Symposium, mentorship opportunities, a network of fellow Golden Ticket alumni, and a cohort of peers to grow alongside. This talk breaks it all down fast — what it is and why it's a stellar experience for young professionals breaking into or already working in the geospatial intelligence realm. *->If you’d like to present or sponsor a future GeoDC Meetup, please complete this [form](https://forms.gle/QbAXPfrDnX12GGaS8).*

A small team of AWS Solutions Architects not traditional software engineers, built AIRE Traffic Control (ATC), a production agentic AI platform now serving thousands of builders. We used AI at every stage: spec-driven development, AI-generated code, automated testing, and agentic workflows. In this talk, we'll share the real story, the architecture, the failures, the breakthroughs, and what we learned about driving adoption from 32% to 92% in 10 weeks. You'll walk away with practical patterns for building multi-agent systems, using AI-DLC methodology, and empowering non-traditional dev teams to ship production-grade applications.

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Join the Columbus AI community for a special event. **Battle of the Personal Agents** is your chance to see what people are actually building with AI agents and personal automation systems. Whether you’re running OpenClaw, Hermes, or a completely custom solution, bring your agent and show the community how it works. We’re interested in real-world implementations: the problems your agent solves, how you use it day-to-day, how it’s hosted and managed, how you built it, and why you’ve chosen to keep using it. Live demonstrations are encouraged, so be prepared to show your code, architecture, workflows, and your agent performing real tasks. This is less about polished presentations and more about sharing practical experience, comparing approaches, and learning from one another. If you’d like to present, please contact Chris Slee (via meetup) before the event so we can allocate enough time for everyone’s demonstrations. Come ready to show what you’ve built, discover what others are doing, and maybe find a few ideas worth taking home. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
