[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“‘Kink’ or ‘Disorder’?”** a look at how psychology approaches unusual sexual behaviors, with Brian A. Sharpless, licensed clinical psychologist, former faculty member at Penn State and Washington State universities and the American School of Professional Psychology, and author of *Psychodynamic Therapy Techniques.* [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://www.ticketleap.events/tickets/profsandpints/dc-kink-or-disorder](https://www.ticketleap.events/tickets/profsandpints/dc-kink-or-disorder) .] Few subjects are as interesting – or as sensitive – as sex. Psychology’s history of dealing with sexual behaviors and, especially, the more unusual among them, has been fraught, in many cases resulting in entirely normal and safe behavior being deemed pathological. In recent decades, however, the field has evolved to be far more open-minded, and to use diagnostic standards focused on the well-being of those involved. Be on hand as Dr. Brian Sharpless, a popular regular on the Profs and Pints stage, discusses how psychologists and psychiatrists approach some of the more unusual sexual behaviors. You’ll learn how the mental-health field historically has thought about, and currently diagnoses and treats, behaviors it deems as crossing the line that separates a quirk or kink from a legitimate psychological disorder. Dr. Sharpless will start by giving us background on exactly how psychologists and psychiatrists determine that a behavior qualifies for “disorder” status. The short answer is that current diagnostic systems do not consider sexual behaviors to be disorders unless they meet certain criteria such as seriously interfering in the life of the person engaged in them or lacking consent among the involved parties. But there’s a lot of nuance to this, which he’ll cover in a manner that is straightforward and understandable. The talk will then offer an in-depth discussion of three paraphilias that can cross the line into being considered as disorders that need to be treated and, in many cases, are illegal: voyeurism, exhibitionism, and frotteurism. Finally, he’ll talk about asphyxiophilia, sometimes called autoerotic asphyxiation, the act of enhancing sexual arousal through the intentional deprivation of oxygen. You may be shocked to learn how many individuals are injured or killed each year while engaging in this potentially dangerous activity. Dr. Sharpless also will discuss fetishistic fantasies and behavior, which are relatively common in the general population but among a small share end up being formally diagnosed as fetishistic disorder. He’ll discuss how fetishes are defined and summarize the research on them. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

**Feb 2:** Would you rather lose your consciousness or lose your body? Are you a body that's alive, or are you something that's experiencing a body? \-\-\-\-\-\-\- ***“I am struck with how rare it is to find a few good friends on the path. It is easy to find people who simply want to sit and be entertained by teachers, or who want to sit and entertain by playing the role of teacher. In other words, the quest for affirmation often outweighs the quest for truth.*** ***Yet you may have one or two good friends, and definitely have one or two waiting to be discovered. Find them; be thankful.”*** ***— Shawn Nevins*** 'What will make me happy in life?' ... 'Am I my thoughts?' ... 'What is Enlightenment?' ... We meet every week to ask questions like these in the pursuit of Self-Knowledge and Truth. We are interested in topics like: Zen, stoicism, spirituality, psychology, mindfulness, Nisargadatta, non-violent communication, Socrates, existential philosophy, Alan Watts, taoism, Eckhart Tolle, meditation, Ramana Maharshi, etc. But we are not affiliated with any dogma, philosophy, or religion. Our goal each meeting is to serve as mirrors for one another using question-based inquiry in a safe environment. In a session, every participant takes turns discussing the week's question or topic, and the group asks reflective questions without any agenda besides trying to understand the person's beliefs. A few other guiding principles of our group: * No one is obligated to share * Be honest with yourself and others * Do not try to convince others to believe or think as you do * Keep the focus on the person being questioned We meet at the [Bethesda Library](https://maps.app.goo.gl/GWMozF8zpY1m1PY26) every Monday.

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Empathy 101,”** a research-based examination of our ability to understand others and how to improve it, with Jamie Keaton Jones, instructor in the Child and Family Social Work Fellowship Program at Walter Reed Military Hospital, adjunct professor at Fordham University, and founder of The Psychotherapy Studio PLLC in Washington D.C. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://www.ticketleap.events/tickets/profsandpints/dc-empathy-101](https://www.ticketleap.events/tickets/profsandpints/dc-empathy-101) .] In these uncertain and divided times, empathy for others—and for ourselves—might be just what we need to reduce our anxiety and constructively work together. Yet many of us lack much of an understanding of our capacity for understanding and how we can nurture it. Take a deep dive into the subject of empathy with Dr. Jamie Keaton Jones, a therapist and university instructor who studies empathy and teaches empathetic skills to students. Drawing on insights from social psychology, neuroscience, and social work, she’ll discuss what exactly empathy is and why it’s necessary for survival. She’ll also dispel common empathy-related myths and review specific ways to practice empathic responses. She’ll talk about mirror neurons—which fire in both someone taking an action and another observing that action—and the important role they play in empathy. She’ll offer guidance on how to assess one’s own level of empathy, and she’ll discuss “empathy deficit disorder” and what it’s like to be excessively empathetic. We’ll discuss how we can best show empathy to a friend or family member in crisis and how can we use empathy to connect when we disagree. Among the questions Dr. Jones will tackle: Can empathy be taught? Can it be captured by Artificial Intelligence? What might the world look like if empathy suddenly ceased to exist? All Profs and Pints talks seek to make people smarter, but this one might help you become kinder as well. (Door: $17, or $15 with a student ID. Listed time is for doors.

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“The Love Lecture,”** a contemplation of matters of the heart, with Laura Papish, associate professor of philosophy at George Washington University and teacher of a seminar on the philosophy of love, sex, and friendship. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://www.ticketleap.events/tickets/profsandpints/hill-center-love-lecture](https://www.ticketleap.events/tickets/profsandpints/hill-center-love-lecture) .] Who wrote the book of love? Why does love have to be so sad? Is it a thin line between love and hate? On a more serious note, how does our society's understanding of love and romantic love shape our experience of it? Why do we think of love as mysterious and irrational? Do those we love need to be lovable? Is love necessarily a morally good thing, or can it actually make it harder for us to be good? Show your love for learning by hearing such questions tackled by Laura Papish, who has built a considerable following among Washington D.C. fans of Profs and Pints with her annual talks exploring the intersection of the brain, the soul, and the heart. Hilariously accompanied by her husband, Chris (on guitar), she’ll offer up a delicious assortment of thoughts about the upcoming Valentine’s Day holiday—some dark, some sweet, and some giving you plenty to chew on. Dr. Papish will start by examining how ancient Greeks thought about erotic love and move on from there, looking at how love is envisioned in modern thinkers, classic novels, recent films, and pop culture. She’ll also discuss the origins of the idea that people have a “soul mate” and how some thinkers have tried to criticize or transform the very concept of love. Together, we'll explore different possibilities for love and those mysteries about it that have left more than a few of us feeling befuddled. Feel free to show up if you are lovelorn, love-stricken, or just love to hear a fascinating discussion. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

Date : Feb 7 2026 13:00 - 15:00 EST Title: Symmetry, Topology, and Magnetoelectric Multiferroicity — Ferroelectric 'Tweezers' for Quantum Magnetism in Hexagonal Ferrites Abstract: The scalability of future quantum and spintronic hardware is currently facing a "physical wall": the challenges of excessive heat dissipation and environmental magnetic noise. To overcome these barriers, materials where magnetism can be controlled with high precision and minimal energy will be highly desirable. Magnetoelectric multiferroic hexagonal rare-earth ferrites (h-RFeO3, R: rare earth) have emerged as an important platform for this mission, offering a unique "playground" where symmetry and topology dictate functionality. In this talk, I will provide a comprehensive overview of research progress on these materials over the last decade. We will explore how a specific structural transition—trimerization—breaks symmetry to create a robust state known as improper ferroelectricity as well as weak ferromagnetism. The coupling between the ferroelectric and magnetic orders leads to a "ferroelectric tweezer" effect, where the material's ferroelectric domain spatially anchors and manipulates magnetic domains. Furthermore, we will address the "readout challenge": how to detect the diminutive magnetic moments inherent in these systems. I will show how the non-coplanar spin topology acts as a signal amplifier, enabling high-fidelity readout of magnetic states through spin-transport. By understanding the "solid science" of these complex oxides, we can define the roadmap for a new generation of stable, low-power topological electronics. Biography: Xiaoshan Xu is Susan J.

Title: Biology-Inspired Neural Networks with Multi-Directional Propagation of Values and Distributions Date: Feb 8 2026 10:00 am - Noon EST Summary: While biological axons can propagate in both directions, current ANNs are focused on unidirectional propagation. Also usually they only propagate values, while uncertainty is shown also crucial for making decisions of biological organisms - suggesting to propagate also variance, probability distributions. I will talk about novel KAN-like approach to ANNs repairing these lack by using neurons containing inexpensive local joint distribution model as polynomial, allowing to freely change propagation direction by just switching indexes, also propagate entire probability distributions represented by vectors of moments. Beside backpropagation, it also allows many additional training approaches, like direct estimation, tensor decomposition, and through information bottleneck.

Dale Gnidovec, Curator of the Orton Hall Museum of Geology at The Ohio State University, will be presenting a program he has wanted to share with us for a long time: Plate Tectonics. His description of his program: Continents on the move - Nothing in Earth history makes sense without moving continents - it tells us why mountains, volcanoes, minerals, and fossils are where they are. This talk examines the evidence for continental drift, why it was disbelieved, and explains how the more-encompassing theory of plate tectonics was developed and eventually proven. Dale is an energetic, incredibly knowledgeable, and very entertaining speaker and this will be another wonderful program by Dale. Hope to see you there! Food and drinks will be provided at the event.

**People Analytics 101: Making Sense of Compensation Data** Compensation data is one of the most widely used and widely misunderstood forms of people analytics. The session will cover where compensation data comes from, including market pricing data, internal payroll data, and benchmarking sources, and how companies think about structuring and analyzing that information. We will explore how compensation data is leveraged to set salary ranges, manage internal equity, support hiring and retention, and align pay with business strategy. A portion of the session will address common data challenges and limitations, such as market noise, inconsistent job matching, and incomplete datasets, while keeping the primary focus on practical use rather than technical depth. The session will also look ahead at where the space is going, including the growing impact of pay transparency laws, expanding pay equity requirements, and emerging regulations in the US and Europe that require organizations to report on gender and pay gaps. The goal is to give attendees a clear mental model for how compensation analytics works today and why getting it right is becoming increasingly critical.

OWASP is ending use of Meetup, so I built an eventbrite for the event. https://www.eventbrite.com/e/ai-development-risk-case-studies-and-how-agentic-ai-is-the-future-of-appsec-tickets-1981450622150?aff=oddtdtcreator AI is transforming how software is designed, developed, and deployed, dramatically accelerating velocity while introducing new categories of risk. As organizations adopt AI-assisted coding, autonomous agents, and increasingly complex model interactions, traditional application security approaches struggle to keep pace. This talk examines emerging AI-driven risks through real case studies from the field, highlighting issues such as insecure code generation, data-leakage pathways, model manipulation, and evolving supply-chain threats. We will explore how engineering teams must adapt their people, processes, and governance models to secure AI-augmented development workflows effectively. The session will then introduce agentic AI as the next evolution in application security—autonomous systems capable of continuous analysis, multi-step reasoning, and real-time remediation. Attendees will learn how combining agentic AI with modern practices can reduce developer friction, improve coverage, and create a future-ready application security strategy designed for the demands of AI-native software development
