Complexity

We are excited to feature **Georgia Channing**, who is currently leading the AI for Science team at **Hugging Face** and will discuss "**When Silicon Meets Carbon: Bringing Synthetic Biology to Life**", lasting approximately 45 minutes. After the talk, seize the opportunity to connect with fellow AI enthusiasts to share ideas and questions while enjoying free drinks and pizza. **Door close by 7.15pm, so please come early! Also, "attend"ing (RSVP) here on Meetup is strictly necessary to be guaranteed entry.** Please note that Meetup has recently been quite keen on promoting its Plus program. However, you are not obligated to purchase it, as both our events and the platform remain free. **Who is this event for?** This event is open to everyone interested in state-of-the-art AI research. We especially design it for students, PhD candidates, academic researchers, and industry professionals with a research focus in machine learning. **Abstract**: Foundation models have transformed how we read and design biological systems, from protein structure prediction to the generation of novel sequences. But building these models is as much an engineering problem as a scientific one. This talk looks at what it takes to bring AI for biology from research into practice, and at the challenges that make science a uniquely demanding domain for machine learning. We will cover how foundation models for biology are trained and deployed at scale, why scientific data is so different from the text and images that drive mainstream AI, and where the gap between a benchmark result and a real biological discovery still lies. The aim is to show how modern AI connects to living systems, and what we need to get right for synthetic biology to fully benefit from it. **Bio**: Georgia Channing is the AI for Science Lead at Hugging Face, working at the intersection of machine learning and the natural sciences. She read for her Master’s and PhD in computer science at the University of Oxford, with a focus on applying AI to scientific discovery. Her work has spanned a wide range of AI-for-science areas, including remote sensing, biophysics, and materials design. She now focuses on building open tools, models, and communities that make scientific research more accessible, collaborative, and reproducible. We are [BLISS](https://bliss.berlin/) e.V., the **AI** **organization** in Berlin that **connects like-minded individuals** who share great interest and passion for the field of machine learning. This summer 2026, we will, again, host an exciting speaker series on site in Berlin, featuring excellent researchers from cohere, ETH Zürich, University of Oxford, HuggingFace, and Stanford University.

The state deals with a lot of money. People and organisations need to declare, file, and pay taxes or receive returns if they overpaid the state. Tax contributions amount to billions of euros, funding public goods such as infrastructure, education, social welfare, and defence. In the 13th edition of our meetup series, we take a closer look at research and design in public finance and taxation, exploring diverse perspectives from 3 speakers. The evening aims to spark a discussion about the government’s or the state’s role, and how it can be accommodating to citizens, residents, and business owners. We will hear from: * Manuel Großmann (Taxfix) * Merici Vinton (formerly US Digital Service) * Sonja Wilczek (DigitalService des Bundes) The federal government’s DigitalService is hosting the meetup on the mezzanine floor of its Kreuzberg office. All presentations will be given in English. Questions in the later discussion part can be raised in either English or German. The event is jointly organised and hosted by CityLAB Berlin and DigitalService.

The TMOD also introduces the key roles and functionaries for that session. **Prepared Speeches:** A significant portion of the meeting is dedicated to prepared speeches. Members working through various projects in the Toastmasters education program deliver speeches based on their chosen projects. Each speech is evaluated by a designated evaluator who provides feedback on strengths and areas for improvement. **Table Topics:** Table Topics is a segment where impromptu speaking skills are tested. The Table Topics Master presents a series of short, unprepared speaking challenges or questions, and members or guests are invited to come to the podium and give a brief, improvised response. **Evaluations:** Following the prepared speeches and Table Topics segment, evaluators provide constructive feedback to speakers. These evaluations focus on content, delivery, body language, and time management. The goal is to help speakers improve their speaking skills. **Reports and Functionary Roles:** The meeting may include various functionary roles, such as the Timer, Grammarian, Ah-Counter, and others, who report on their observations and contributions to the session. These roles help members improve their language and time management skills. **General Evaluator:** The General Evaluator provides an overall assessment of the meeting, highlighting what went well and offering suggestions for improvement. They may also evaluate the evaluators' performance. **Awards and Recognitions:** Toastmasters sessions often conclude with awards and recognitions, including the Best Speaker, Best Evaluator, and Best Table Topics Speaker. These awards encourage members to strive for excellence in their speaking and leadership abilities. **Closing:** The meeting concludes with closing remarks from the Toastmaster of the Day, who may express gratitude to participants and encourage them to continue their Toastmasters journey. **Networking and Socialising:** After the formal meeting, members and guests often have the opportunity to network, socialise, and discuss their experiences in a more relaxed setting.

For the June edition of our collaborative modeling meetup, we’ll continue the EventStorming deep dive we started earlier this year and explore some of the tactics and recipes of this format. What does that mean, exactly? Massive learning, massive fun, and massive numbers of sticky notes. As always, everyone is welcome. You don't need to be a software engineer to participate. In fact, it would be great to have more people who aren't software engineers. We're here to solve problems cross-functionally, not get into implementation details. As long as you care passionately about getting things right, then you belong here! This is a hands-on workshop. Be prepared to participate fully and add to the energy of the room. Looking forward to seeing you there!

Bring your laptop! **​Abstract:** Large language models are increasingly useful not only for writing code, but for exploring the space of possible algorithms. In this hands-on workshop, we will look at how LLMs can act as “heuristic scientists”: generating candidate strategies, turning ideas into executable code, testing them against concrete objectives, and refining them through feedback. The workshop centers on the general discovery loop behind LLM-assisted heuristic generation. Participants will learn how to structure problems for algorithm discovery, prompt models to propose interpretable heuristics, evaluate those heuristics with simulations or benchmarks, and use the results to guide further search. We will also discuss when simple prompting is enough, when training or fine-tuning may help, and how to keep generated heuristics understandable, testable, and auditable. ​By the end of the session, participants will have built a small discovery loop of their own and will understand the practical trade-offs involved in using LLMs for open-ended algorithm discovery: creativity versus control, exploration versus verification, and automation versus human judgment. ​ **⚡ FINAL REMINDER ⚡** **You MUST register and be approved on Luma to attend.

Riverty Tech Night in collaboration with KI Park and cloud ahead Most of what we've built over the last \~15–20 years assumes a static frame of reference: Apps talk to services over APIs. You know who's calling what, you can stick a gateway in front of it, apply some policy, and move on. Agents don't really fit that model. They don't just call an API and return. They decide what to do, call a tool, look at the result, call something else, maybe involve another agent, loop through an LLM a few times… all the while, doing onbehalf of the user, with permissions that aren't always obvious. It's not always clear who is actually doing something. It's not obvious what the full execution path looks like. And the access control models we're used to — user → service, service → service fall part. We'll dig into what actually breaks when you start wiring agents into real systems, especially around identity and access control. Things like: \- how \(or if\) you assign identity to an agent \- what it means for an agent to act "on behalf of" someone \- how you enforce policy when the flow isn't predefined \- and how you get any kind of visibility into what just happened We'll also look at some of the patterns starting to emerge: agents talking to other agents, tools being invoked dynamically, and why a mediation layer (ie, agentgateway) must be built from the ground up with this in mind. \-\-\-\-\-\- Speaker \-\-\-\-\-\- Christian Posta ([Solo.io](http://solo.io/)) Christian is a globally recognized expert in cloud-native architecture, service mesh, and distributed systems.

I have been studying the question of "self" online with Prof. Ellie Anderson and so I thought a prompt on the "self" might be interesting. Full confession: I had Claude create this prompt and I like it, so here goes: Imagine a thought experiment that merges two classic puzzles: > You undergo a procedure, performed neuron by neuron, in which every biological component of your brain is replaced with a functionally identical synthetic substitute. At each step, your behavior, memories, and personality remain unchanged. When the last neuron is swapped, is the consciousness experiencing the world still you? And — more pressingly — was there ever a continuous "you" to begin with? ### Questions to Wrestle With * If consciousness is purely physical, does the *gradual* nature of the replacement matter, or is it equivalent to being destroyed and rebuilt? * Could there be a "self" without continuity of experience — even moment to moment, while you sleep? On a more practical level, consider the simpler case first: **hemispherectomy** patients — people who have had an entire cerebral hemisphere surgically removed — often retain a strong sense of personal identity and continuity. This suggests "you" are not rigidly tied to specific physical material. But does that vindicate the synthetic neuron case, or merely show that identity is more *flexible* than we thought — not that it can survive *complete* substrate replacement? I used Claude so I could get this out today and let everyone have some time to consider it. Hope to see you at the Oracle. Sorry about the location change two weeks ago. That's what I get for trusting local weather predictions!

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!

**How does a TennisColumbus Season / League run?** The league advertises the season dates and builds a queue of committed players for the season. **Kickoff Day - June 10th** The start day of the season, players are sent a kickoff email that contains important information about the league, the link where your league standings and players contact information. We guarantee 6 playing partners at your playing level, but have been averaging closer to 15+ partners in most cities. The number of different levels we run is solely based upon the number of players enrolled for the league kickoff. Typically we are running a Skilled-3.0, Competitive-3.5 and Advanced-4.0 in most cities. **Your Task - "Flexible Scheduling"** After this kickoff email is sent, it is the **player's task to communicate with other players**. Players should work with their partners to find an agreeable time and location to play the match. While TennisColumbus doesn't mandate your playing schedule, it is recommended that players schedule at least one match per week. By request of the players, we started to allow players to play 1 rematch per season. The regular season is all about playing as much as you can. As of Feb. 10, 2026 we've had an amazing 2,017 players play more than [20 matches in a season](https://www.tenniscolumbus.com/info/MatchesInSeason). **Where to Play?** Play at your local free tennis courts, tennis parks, condo courts or tennis clubs. The league strongly suggests that players jointly try to pick a tennis court location convenient to both. We provide an extensive list of [tennis courts](https://www.tenniscolumbus.com/TennisCourts), including # of courts, lighting, hitting walls, etc. We strive to keep this list up-to-date. TennisColumbus sets up a must play dates to push players out on the courts. The final deadline is the date marking the end of the season, at which point players with 3-5 wins (Actually total is specified on the division page) will qualify for a post-season playoff to determine the league champion. **How to Play?** Players can use three mostly standard playing formats: 2 out of 3 sets, 2 sets with 10 point super tie-breaker or the 10-game pro set (First to 10, used when court time is limited). On Feb. 2018, we added Fast Tennis 4 game pro set format as a valid format. **Playoffs** Each season concludes with a playoffs where players with anywhere from 3 to 5 season wins qualifies for a single elimination tourney. The champion is awarded based upon the league [Prize Pool](https://www.tenniscolumbus.com/info/prize_pool3). Each singles league champion also receives a playing entry into one of two national championships we run. **[JOIN TODAY](https://www.tenniscolumbus.com/join)** Full price is $39.95 to play in a season. The earlier you sign up we typically offer discounts during these tough economic times. Just go to the [Join Page](https://www.tenniscolumbus.com/join) and complete the short form. We'd be happy to find you dedicated tennis playing partners.
