Profs & Pints DC presents: Horror as Queer
[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Horror as Queer,”** a look at the influence and depiction of queerness in horror films, with May Santiago, adjunct professor of film studies at George Mason University and producer of the podcast *Horrorspiria.*
[Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-horror-queer](https://events.ticketleap.com/tickets/profsandpints/dc-horror-queer) .]
Horror was queer long before both Brad and Janet succumbed to the charms of Dr. Frank-N-Furter in *The Rocky Horror Picture Show.* In fact, one could make the argument that, for both better and worse, the history of horror films is the history of queers on film. Film scholar May Santiago will do just that, with plenty of vivid examples, in reprising a talk that has earned rave reviews.
You’ll learn how queer auteurs such as F.W. Murnau and James Whale were there at the very beginning. Murnau played a central role in the German expressionist movement that gave rise to films such as *Nosferatu*, while Whale left a body of work full of queer codes, including the films *Frankenstein*, *The Old Dark House*, and *The Invisible Man.*
From there, Santiago will discuss how the representational codes established by such queer filmmakers were appropriated throughout the celluloid century by non-queer authors who constructed cinematic horror language that used queerness as shorthand for the monstrous. The result was harmful stereotypes of queer people in films and society, with examples being the stoic psycho lesbian trope embodied by Mrs. Danvers in *Rebecca*, the transgender sex-obsessed serial murderer Norman Bates in Alfred Hitchcock’s *Psycho*, and the villains of *Dressed to Kill* and *Silence of the Lambs.*
Yet, even with these negative portrayals of explicit or implicit queerness, horror cinema’s relationship with queerness and queer audiences has grown stronger with each passing decade, with queer authors and queer audiences reclaiming the monstrosity that created the basis of the horror genre. Santiago will look at how the evolution of horror films coincided with that of queer stereotypes and how queer authors embedded queerness in films that aren’t explicitly queer. Among the questions she’ll tackle: How did we come around to thinking that the Babadook was gay? ? (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.)

The Cash-Flow Breakfast Club - Fairfax VA - REI Education & Networking event
Fairfax County VA Real Estate Investors, Agents and Professionals!
We just launched a Cash-Flow Breakfast Club for your area! This is the most unique real estate investor club, education, networking and mastermind event in the US!
**Join us for our official launch event for Fairfax County VA** **on June 1.**
**This is a 12 part education series with new topics every month. This event is session 3 of 12!**
**This event is free but has very limited seating and we are limited to the first 50 to RSVP! Join us and become a founding member of this amazing community!**
**Very limited seating. In-person only.**
**Make sure to RSVP today to reserve your spot.**
**When: June 1, 2026 @ 5:45PM – 9:00PM EST**
**Where: 12700 Fair Lakes Circle, Ste. 120**
**Fairfax, Virginia, 22033**
The Cash-Flow Breakfast Club is NOT just a meet up. It’s the most unique Real Estate Investor Community of Mentors, Coaches & Masterminds. A community of growth oriented, abundance mindset, go-giver individuals with a BARE MINIMUM commitment to become financially free through real estate investing.
We focus on providing education and building networks to help every member solve their cash-flow freedom equation, so they can have the time-freedom needed to follow their passions, make a lasting impact and even change the world! The unique format of this event, which consists of high-level education, gamified networking, mastermind breakout sessions, case studies, group deal analysis, market deep dives, and peer-to-peer coaching facilitation makes this the most impactful local real estate investor group a real estate investor can be a part of.
The foundation of the group is built around the belief that everyone in the room has the potential to change the world… however most of us never have the time, energy or financial situation to even dare to dream big enough. Most of us have passions that will never be followed, amazing businesses or ideas that will never be pursued… unless we can solve the Cash-Flow Freedom Equation, which ultimately leads to Time-Freedom. Once that happens it is usually much easier for us to think bigger, dream bigger, be bigger.

Machine Learning for Reliable Quantum Computing: An Algorithm–Hardware
Date: June 7 2026 Sunday 10:00 am - Noon EDT
Full title: Machine Learning for Reliable Quantum Computing: An Algorithm–Hardware Co-Design Perspective
Summary: Reliable quantum computing requires co-design across the full stack, including algorithm structure, compilation, and execution, rather than isolated optimization of any single layer. This talk presents a unified framework in which these layers are jointly optimized under realistic hardware constraints. Structure-aware compilation exploits algorithmic interaction graphs to reduce circuit depth; joint optimization across mapping, term ordering, and algorithm parameters yields significantly improved success probability; and execution-layer analysis reveals that error mitigation effectiveness depends critically on circuit symmetry and native gate choice. While demonstrated on superconducting quantum processors, the underlying co-design principles are potentially transferable across architectures. Building on this foundation, the talk highlights machine learning as the key enabler for closing the feedback loop: data-efficient, parameterized noise models learned directly from workload execution data achieve substantially improved predictive fidelity over vendor models without the overhead of dedicated characterization. These insights situate the co-design perspective within the emerging framework of quantum deep learning. In this broader setting, the talk also presents an operational definition, a unifying taxonomy, and a benchmarking protocol grounded in explicit resource contracts.
Speaker: Dr. Yanjun Ji has an interdisciplinary research background in Physics and Computer Science. In 2020, she completed my Master's degree in Theoretical Physics at Saarland University. In 2024, she earned her Ph.D. in Computer Science at the University of Stuttgart. She is currently a postdoctoral researcher at Forschungszentrum Jülich. She is committed to interdisciplinary research at the cutting-edge convergence of quantum computing and artificial intelligence. Her research encompasses both foundational theoretical investigations and the development of practical applications, aiming to serve society and benefit humanity.

Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required.
🛠️ What to Bring
Laptop: Fully charged and ready to go.
AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!)

In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them.
Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance".
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
