Language shared online through social media or messaging reflects people's thoughts and emotions. Processing this data with Natural Language Processing (NLP) and machine learning can reveal mental health and psychological traits. For example, analyzing Facebook posts enables me to predict depression before it is clinically diagnosed and highlight particular symptoms. At the population level, billions of geo-tagged Tweets can be used to monitor health risk patterns, including depression and anxiety trends across communities. Beyond assessment, I'm using Large Language Models (LLMs) to improve mental health care, including training therapists and assisting with Cognitive Behavioral Therapy. These applications of NLP and Al may lead to earlier and more effective interventions and improved access for underserved populations.

AI + Music Seminar - The meeting will consist of introductions and organizational discussions, aimed at understanding participants' interests. We'll discuss what the seminars can focus on going forward.
You are cordially invited to attend the biweekly Brookhaven AI Mixer (BAM). BAM includes one short talk on AI research happening at BNL, followed by an open mixer over coffee and snacks for everyone to network and discuss all things AI. The first half hour will consist of presentations that will be available via ZOOM, and the second half hour will be for in person only networking.
Abstract: Designing custom proteins could revolutionize medicine and materials, but it remains an immense scientific challenge. Our work uses large-scale AI foundation models to generate novel proteins tailored to bind specific small molecules. Each AI-generated design is passed through a rigorous, multi-stage validation pipeline to ensure it is biophysically realistic. A key innovation is fine-tuning our model with data from molecular dynamics (MD) simulations, exposing it to the conformational dynamics and energetics of protein-ligand binding. This physics-aware training results in novel protein designs with enhanced stability and more effective binding capabilities.

Abstract: Artificial Intelligence (AI) is no longer a futuristic concept -- it is here, but its development, benefits, and risks remain unevenly distributed across industries, nations, and social groups. In this talk, Jieshu presents her research on the societal dimensions of AI from two perspectives: the forces shaping AI's development (backward-looking) and its current and potential impact on society (forward-looking). She first examines disparities in AI, including women's underrepresentation in AI patents and the geographic concentration of AI innovation, highlighting inequalities in who creates AI and who benefits from it. She then explores AI's societal impact, focusing on workforce transformation and the need for GenAI literacy. She will also discuss AI patents, AI's role in climate change mitigation and adaptation, potential environmental biases in LLMs, and gender-specific patterns in AI portrayals in science fiction.
Bio: Jieshu Wang is a Postdoctoral Research Scholar at Arizona State University (ASU), focusing on the social dimensions of artificial intelligence (AI). With a background in engineering, economics, communication, and science and technology studies, she examines how AI both shapes and is shaped by broader societal forces. Her research employs interdisciplinary methods to explore the social, political, and economic factors influencing AI development, as well as its role in innovation, the economy, the future of work, climate change mitigation, and popular culture. Jieshu holds a Ph.D. in Human and Social Dimensions of Science and Technology from ASU. She is also a science book translator and has translated six books.

Abstract:
Today's distributed transaction processing systems must deal with untrustworthy environments where multiple mutually distrustful entities communicate with each other, and maintain data on untrusted infrastructure. Byzantine Fault-Tolerant (BFT) protocols have recently been extensively used by distributed transaction processing systems to establish consensus on the order of transactions. However, the proliferation of different BFT protocols has made it difficult to navigate the BFT landscape, let alone determine the protocol that best meets application needs. Moreover, as novel smart contracts, modern hardware, and new cloud platforms arise, future-proof distributed transaction processing systems need to be designed with full-stack adaptivity in mind. This talk presents our vision for a reinforcement learning (RL)-based distributed transaction processing system that adjusts effectively in real-time to changing fault scenarios and workloads.

Natural Language Understanding and Semantic Parsing
(Partly joint work with former colleagues at Elemental Cognition)
Semantic parsing refers to the task of determining the propositional content of language: who did what to whom. It is part of the larger task of natural language understanding (NLU). I will start out by discussing what full NLU means, and argue that we are still far away, as a field, from solving full NLU, or even from knowing how to evaluate it.
In the second part of the talk, I will situate semantic parsing in the context of several other NLU subtasks. Typically, the target representation of semantic parsing uses an ontology (such as PropBank or FrameNet). Semantic parsing includes the subtasks of word sense disambiguation, argument detection, and argument role labeling. I will discuss choices among possible target ontologies. I will justify why we created a new ontology, Hector, based on FrameNet and the lexical resource NOAD, and explain some of its characteristics.
In the third part of the talk, I will present experiments we performed using transformer models. We obtain best results using a two-phase model, in which we first choose the frame, and then, given the frame, choose the arguments. We encode the problem for both tasks using indices in the sentence. While we develop the parser for our new ontology Hector, this approach also beats the state of the art for FrameNet and PropBank parsing.Biography: I am a professor in the Department of Linguistics at Stony Brook University with a joint appointment in IACS.
