SOLD OUT-Profs & Pints DC: The Happiness Workshop
**This talk has completely sold out in advance and no door tickets will be available. You must have an advance ticket to attend**.
[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“The Happiness Workshop,”** a look at what recent research and centuries of wisdom tell us about bringing more joy and contentment to our lives, with Eric Zillmer, professor of psychology and the director of the Happiness Lab at Drexel University.
[Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-happiness-workshop](https://events.ticketleap.com/tickets/profsandpints/dc-happiness-workshop) .]
Are you happy? If not, how do you get there?
Gain insights into happiness with Eric Zillmer, an award-winning teacher who leads a creative think tank that investigates the ingredients for happiness among individual people and communities.
You’ll learn how the study of happiness is a growing, evidence-based field known as positive psychology, which aims to find solutions to happiness challenges that can bring positive change to our lives and environments.
Dr. Zillmer will discuss the meaning of happiness and its place in our lives and society. He’ll draw from recent science and great thinkers in discussing how we can increase our own happiness and well-being, throwing out a few practical tips as well.
He’ll talk about whether happiness can be measured and where in our brain happiness is located. We’ll look at the influence of socializing and social media on our happiness and about the roles that music, humor, adversity, and regret have in happiness research.
Dr. Zillmer will discuss what we learn about happiness from competitive sports, and he’ll suggest ten actions that you can engage in that will make you happier.
Among the questions he’ll tackle: What is the happiest day of the week? Can a specific place make you happy? What can we learn about happiness from travelling the world? (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

Green Technology Events This Week
Discover what is happening in the next few days
Tech & Truth Café
An open space for real conversation about how technology is shaping our world, and how we can respond with wisdom, purpose, and values.
## COMING UP:
## Life with Augmented Intelligence
**Shaping how we live, work, and build in an AI-driven world**
From assistants → to collaboration → to autonomous systems
***
**A different way of thinking, working, building.**
Most people are still using AI at the surface.
Answers. Shortcuts. Quick help.
But underneath, work is starting to look different:
* systems instead of tasks
* collaboration instead of commands
* design instead of effort
This is a space to step into that.
Not a workshop.
Not a panel.
A place to see what’s emerging, hear how others are thinking, and explore what it means for your own life and work.
***
## Tech & Truth Café
📍 Greencourt Innovation Center
🗓️ May 10 & 17
🕐 1:30 – 5:00 PM
1:30 → arrive and connect
2:00 → ideas and conversation
3:00 → demos and exploration
4:30 → wrap up
***
**WHO:**
If you’ve been experimenting with something interesting,
building something, or thinking differently about AI…
reach out. We’d love to include you in the conversation.
***
**Bring a laptop.**
***
For people who feel like:
“there’s more to this than what I’m currently doing with AI.”
**Come be part of it.**
**WHO**
**For people who feel like:** "There's more to this than what I'm currently doing with AI." Come be part of it.
**WHAT TO EXPECT**
Falls Church, VA. AI at Work: Productivity vs. Replacement Anxiety
**IMPORTANT! Please register on [Luma page](https://luma.com/klm98cuc)**
*Ignore the displayed time — it’s 5:30pm VA time.*
AI is making us faster than ever — and at the same time, quietly questioning our place at work.
We’re all feeling it: tools that boost output in minutes, automate entire workflows, and sometimes… do the job better. So where does that leave the human?
This conversation dives straight into that tension — no sugarcoating, no generic optimism. Just real perspectives from people working inside the shift.
**Speakers:**
[Nina Borysova, MBA ](https://www.linkedin.com/in/nborysova/?utm_source=luma)**Director, Product Management Technical (PMT), Data Analytics and AI Solutions, Mastercard**
****[Dr. Volodymyr Tkach ](https://www.linkedin.com/in/volodymyr-tkach/?utm_source=luma) CEO \| Ph\.D\, Associate Professor \| MIT Research Fellow \| Cybersecurity\, Threat Intelligence\, Anomaly Detection\, Artificial
**We’ll unpack:**
– where AI actually boosts productivity vs. where it replaces thinking
– which roles are evolving — and which are quietly disappearing
– how teams are restructuring around AI (and what that means for individuals)
– how to stay valuable when execution becomes automated
– what “creative work” even means when AI can generate ideas on demand
– the psychological side: anxiety, denial, adaptation
If you’re feeling both excited *and* uneasy about AI — you’re not alone. And you probably shouldn’t ignore either feeling.
Come for clarity. Leave with a more honest map of what’s ahead.

Building Scalable Customer Identity Resolution Pipelines on AWS Using AI
Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs.
This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context.
We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing.
