#30 AI Series: Microsoft Security Response Center - A. Salem
**Join the FINALE of the free BLISS AI Speaker Series Winter 2025/26!**
We are excited to feature **Ahmed Salem**, who is currently a Researcher at **Microsoft Security Response Center (MSRC)** and will discuss **"The Price of Intelligence: Three Risks Inherent in LLMs**", 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**: As LLMs move from passive assistants to action taking agents, the price of intelligence is increasingly paid in control failures: what the model treats as instruction, how behavior shifts across time and context, and how fragile safety properties can become under downstream adaptation. In this talk, we begin with indirect prompt injection as an end‑to‑end problem, where untrusted content can steer downstream actions in realistic pipelines. We then discuss a defense direction that secures agent planning through deterministic policy enforcement and principled control over what information is exposed during planning. Finally, we turn to a practical question that underlies all of these results: how do we know when an agent/LLM is actually safe, rather than merely scoring well on an evaluation? We highlight two factors that can systematically distort safety measurement in agent settings. First, reasoning models can change compliance when they infer they are being evaluated (“test awareness”), which can bias apparent robustness and complicate safety audits. Second, we discuss implicit memory as a hidden channel that challenges the “stateless” assumption and enables temporal behaviors that standard evaluation setups may fail to surface.
**Bio**: [Ahmed](https://ahmedsalem2.github.io/) is a Researcher at the Microsoft Security Response Center (MSRC), focusing on machine learning privacy, biomedical data privacy, and applied cryptography. He was previously a Postdoctoral Researcher at Microsoft Research Cambridge (2022–2024). He received his PhD in Computer Science from CISPA Helmholtz Center for Information Security, Saarland University, under the supervision of Michael Backes and Yang Zhang, graduating *summa cum laude*. Before that, he earned his MSc in Computer Science from Saarland University with high honors and his BSc in Digital Media Engineering from the German University in Cairo. His work has appeared at ICML, USENIX Security, CCS, NDSS, and Oakland.
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 winter 2025/26, we will, again, host an exciting speaker series on site in Berlin, featuring excellent researchers from Tübingen AI Center, DeepMind, Microsoft, King's College London, cohere, and ETH Zürich.

Designing the next interface: From local experiences to AI-powered workflows
*Please note, this event is free but please sign up here so we can inform the venue of your attendance: [https://uxdx.com/community/community-berlin-2026-02-10/](https://uxdx.com/community/community-berlin-2026-02-10/)*
Design is changing — both in what we build and how we build it.
This month we’ll explore how teams are designing more local, trust-driven experiences that connect online and offline behavior, and how AI is reshaping the way designers move from idea to working prototype. Together, these perspectives show how design is evolving at both the strategic and execution levels: from what we build for people, to how quickly and effectively we can build it.
**AGENDA:**
**6:00 PM:** Registration and networking
**6:20 PM:** Welcome from UXDX Berlin
**6:30 PM:** Talk: *"From Marketplaces to Neighborhoods"* with **[Yihui Liu](https://www.linkedin.com/in/yihui-liu-b98627121/),** Product Design Lead, eBay
An exploration on how eBay uses design to shift their experience from a global marketplace to a more local, human, and connected ecosystem.
**7:00 PM:** Talk: *"3 Months to 2 Weeks: Using AI to Build MVPs in a Single Design Sprint"* by **[Behrad Mirafshar](https://www.linkedin.com/in/behradmirafshar/),** CEO, Bonanza Studios
Practical walkthrough of how they've compressed the design-to-working-prototype cycle using tools like Claude Code + Figma Make. What works, what doesn't, and where the hype falls short.
**7:30 PM:** Closing Remarks
**7:40 PM:** Networking
Thank you [Delivery Hero](https://www.deliveryhero.com/) for supporting the event.

**3 Months to 2 Weeks: Using AI to Build MVPs in a Single Design Sprint**
Design tools come and go. The craft stays. Over the past year at Bonanza I've been testing where AI actually fits into how we work. Not as a replacement for thinking, but as a way to show up to a design sprint with something tangible. We now walk into day one with a working prototype. Clients see real interactions, not wireframes. Conversations shift from "imagine this" to "try this." That compression changes everything downstream.
On February 10th, I'm breaking down our process at the UXDX Community event in Berlin. How we use Claude Code and Figma Make to go from brief to functional MVP in two weeks. What worked, what flopped, where the hype doesn't hold up. If you're a product leader or designer trying to figure out where these tools actually fit, this one's practical.

* 20:40 - Networking, Open Mic Lightning Talks
* Mingle until 21:30pm
🗣️ **Talks**
**➡️ Modernizing Your React App: Compiler, useEffectEvent, Activity & Friends**
*React has changed a lot in the last year: React 19, 19.1 and now 19.2 brought a stable React Compiler, new hooks like useEffectEvent, the \ API, and better SSR primitives such as Partial Pre-rendering. And more*
*In this talk we’ll take a demo React app that’s full of effects, memoization and “old school” patterns, and modernize it step by step.*
**➡️ A Triplestore-Powered BaaS: Real-Time Collaboration Without the Backend**
*Backend-as-a-Service platforms promise simplicity, but often lock developers into complex APIs authorization rules. What if your frontend could directly manage data, authorization, and collaboration - without domain-specific backend code?*
*In this talk, Oliver shares how he built a triplestore-based BaaS to power real-time collaboration in his side project MonsterWriter, and how the approach grew into an independent open-source project. We’ll see how LinkedRecords.com enables fine-grained authorization, simplifies real-time collaboration, and supports a Bring Your Own Backend model that gives organizations more control over their data and vendor relationships. It is also shown how global state management becomes a lot easier in React apps.*
**➡️ Building Cross-Platform Agentic UI at Superhuman**
*Recently, Superhuman (formerly Grammarly) launched Superhuman Go, an AI assistant that works alongside you on every platform. To build it, we needed a scalable solution that supports an unlimited number of agents that dynamically shapes the user interface and looks similar across all supported desktop and mobile platforms. Join me to find out how we discovered solutions for this innovative new product.*

The Lineup for the evening
**Talk 1: How Data (Science) is Transforming Professional Sports**
**Abstract**: From Moneyball's linear regression revolution to AlphaGo's Move 37, data science has fundamentally reshaped how we understand and play sports. This talk explores three key dimensions of this transformation: first, how analytics revolutionized scouting and training—from the Oakland Athletics' 20-game winning streak to Liverpool FC ending their 30-year championship drought through data-driven player selection. Second, how machine learning and real-time tracking systems have changed gameplay itself, making the mid-range jump shot obsolete in basketball and revealing chess strategies that had eluded grandmasters for thousands of years. Finally, we'll examine the darker consequences, including how ML-powered microbetting has transformed sports gambling into a $149 billion industry that resembles slot machines more than traditional wagering.
This talk offers insights spanning baseball, soccer, basketball, chess, and Go - demonstrating how data science doesn't just optimize existing strategies, it fundamentally questions the assumptions entire sports were built upon.
**Speaker**: Kaan Isik
**Bio**: Kaan Isik is a Data Scientist at GetYourGuide where he works on the Activity Ranking team. As a member of this team, he focuses on developing and optimizing the learn-to-rank deep learning model that powers real-time activity recommendations for millions of travelers worldwide. His work directly impacts how users discover activities across GetYourGuide's platform, making their travel planning more personalized and efficient.
**Talk 2: Can Foundation Models outperform classic ML on structured data? Hands-on experience with TabPFN**
**Abstract**: LLMs excel at generalising over text data, but cannot reliably predict outcomes from spreadsheets and databases, which drive most critical decisions across medicine, finance, science and virtually all industries. In this talk, we will showcase how TabPFN, Tabular Foundation Model developed by Berlin-based Prior Labs, successfully generalises over structured data problems, beating classic ML with win rates ranging from 100% to 87%.
**Speaker**: Diana Kriuchkova
**Bio**: Diana is leading Product at Prior Labs. She is a part of the team developing TabPFN, a foundational model for tasks on structured data. TabPFN was published in the 2025 issue of Nature journal, and has shown to beat classic ML methods like XGBoost in >80% of cases. Diana's former background is in machine learning, and she spent last years leading product at developer-focused startups in Berlin.
**Lightning talks**
There will be slots for 2-3 Lightning Talks (3-5 Minutes for each) between the two main talks.
Kindly let us know if you would like to present something :)

DoJo (Informal Python Meeting)
**New Dojo Location!**
**Draft Day Columbus**
1130 Dublin Road
Columbus, OH 43215
We're going to try a new dojo location for a few weeks and see how it works
Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead.
We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)
