On this episode of Advances in Care , host Erin Welsh and Dr. Craig Smith, Chair of the Department of Surgery and Surgeon-in-Chief at NewYork-Presbyterian and Columbia discuss the highlights of Dr. Smith’s 40+ year career as a cardiac surgeon and how the culture of Columbia has been a catalyst for innovation in cardiac care. Dr. Smith describes the excitement of helping to pioneer the institution’s heart transplant program in the 1980s, when it was just one of only three hospitals in the country practicing heart transplantation. Dr. Smith also explains how a unique collaboration with Columbia’s cardiology team led to the first of several groundbreaking trials, called PARTNER (Placement of AoRTic TraNscatheteR Valve), which paved the way for a monumental treatment for aortic stenosis — the most common heart valve disease that is lethal if left untreated. During the trial, Dr. Smith worked closely with Dr. Martin B. Leon, Professor of Medicine at Columbia University Irving Medical Center and Chief Innovation Officer and the Director of the Cardiovascular Data Science Center for the Division of Cardiology. Their findings elevated TAVR, or transcatheter aortic valve replacement, to eventually become the gold-standard for aortic stenosis patients at all levels of illness severity and surgical risk. Today, an experienced team of specialists at Columbia treat TAVR patients with a combination of advancements including advanced replacement valve materials, three-dimensional and ECG imaging, and a personalized approach to cardiac care. Finally, Dr. Smith shares his thoughts on new frontiers of cardiac surgery, like the challenge of repairing the mitral and tricuspid valves, and the promising application of robotic surgery for complex, high-risk operations. He reflects on life after he retires from operating, and shares his observations of how NewYork-Presbyterian and Columbia have evolved in the decades since he began his residency.

In this episode, Šimon Mandlík, a PhD candidate at the Czech Technical University will talk with us about leveraging machine learning and graph-based techniques for cybersecurity applications. We'll learn how graphs are used to detect malicious activity in networks, such as identifying harmful domains and executable files by analyzing their relationships within vast datasets. This will include the use of hierarchical multi-instance learning (HML) to represent JSON-based network activity as graphs and the advantages of analyzing connections between entities (like clients, domains etc.). Our guest shows that while other graph methods (such as GNN or Label Propagation) lack in scalability or having trouble with heterogeneous graphs, his method can tackle them because of the "locality assumption" – fraud will be a local phenomenon in the graph – and by relying on this assumption, we can get faster and more accurate results. ------------------------------- Want to listen ad-free?

Our guest in this episode is David Tench, a Grace Hopper postdoctoral fellow at Lawrence Berkeley National Labs, who specializes in scalable graph algorithms and compression techniques to tackle massive datasets. In this episode, we will learn how his techniques enable real-time analysis of large datasets, such as particle tracking in physics experiments or social network analysis, by reducing storage requirements while preserving critical structural properties. David also challenges the common belief that giant graphs are sparse by pointing to a potential bias: Maybe because of the challenges that exist in analyzing large dense graphs, we only see datasets of sparse graphs? The truth is out there… David encourages you to reach out to him if you have a large scale graph application that you don't currently have the capacity to deal with using your current methods and your current hardware. He promises to "look for the hammer that might help you with your nail".…

Together we delve into specific scenarios in which Graph Databases provide unique solutions, such as in the fraud industry, and learn how to optimize our DB for questions around connections, such as "How are these entities related?" or "What patterns of interaction indicate anomalies?" This discussion sheds light on when organizations should consider adopting graph databases, particularly for cases that require scalable analysis of highly interconnected data and provides practical insights into leveraging graph databases for performance improvements in tasks that traditional relational databases struggle with.…
In this episode, Adam Machowczyk, a PhD student at the University of Leicester, specializes in graph rewriting and its intersection with machine learning, particularly Graph Neural Networks. Adam explains how graph rewriting provides a formalized method to modify graphs using rule-based transformations, allowing for tasks like graph completion, attribute prediction, and structural evolution. Bridging the worlds of graph rewriting and machine learning, Adam's work aspire to open new possibilities for creating adaptive, scalable models capable of solving challenges that traditional methods struggle with, such as handling heterogeneous graphs or incorporating incremental updates efficiently. Real-life applications discussed include using graph transformations to improve recommender systems in social networks, molecular research in chemistry, and enhancing IoT network analysis.…
In this episode, the data scientist Wentao Su shares his experience in AB testing on social media platforms like LinkedIn and TikTok. We talk about how network science can enhance AB testing by accounting for complex social interactions, especially in environments where users are both viewers and content creators. These interactions might cause a "spillover effect" meaning a possible influence across experimental groups, which can distort results. To mitigate this effect, our guest presents heuristics and algorithms they developed ("one-degree label propagation”) to allow for good results on big data with minimal running time and so optimize user experience and advertiser performance in social media platforms.…

In this episode we discuss the GitHub Collaboration Network with Behnaz Moradi-Jamei, assistant professor at James Madison University. As a network scientist, Behnaz created and analyzed a network of about 700,000 contributors to Github's repository. The network of collaborators on GitHub was created by identifying developers (nodes) and linking them with edges based on shared contributions to the same repositories. This means that if two developers contributed to the same project, an edge (connection) was formed between them, representing a collaborative relationship network consisting of 32 million such connections. By using algorithms for Community Detection, Behnaz's analysis reveals insights into how developer communities form, function, and evolve, that can be used as guidance for OSS community managers.…
