Srikanth Ramaswamy - What Can Artificial Neural Networks Learn From Biological Neuromodulatory Systems (TSVP Talk at OIST)
Srikanth Ramaswamy is visiting OIST from 2024-04-30 until 2024-08-29 through the "Theoretical Sciences Visiting Program" (TSVP). Find out more about the TSVP on the program website:

Abstract: Neuromodulators are signalling chemicals in the brain, which control the emergence of adaptive learning and behaviour. Neuromodulators including dopamine, acetylcholine, serotonin and noradrenaline operate on a spectrum of spatio-temporal scales in tandem and in opposition to reconfigure functions of biological neural networks and to regulate global cognition and state transition. Although neuromodulators are important in shaping cognition, their phenomenology is yet to be fully realized in artificial neural networks (ANNs). In this talk, I will first give an overview of the biological organizing principles of neuromodulators in adaptive cognition and highlight the competition and cooperation across neuromodulators. I will then discuss ongoing research on bio-inspired mechanisms of neuromodulatory function in ANNs and propose a computational framework to incorporate their diverse functional settings and inspire new architectures of “neuromodulation-aware” ANNs.
Profile: Dr. Srikanth Ramaswamy, is a Marie Curie Fellow, a Lister Prize Fellow and an Assistant Professor in computational neuroscience at Newcastle University. He is also a Fulbright Scholar at MIT and a Theoretical Sciences Visiting Scholar at OIST. He directs the Neural Circuits Laboratory at Newcastle University. His research focuses on the role of neuromodulators in shaping cognition in biological neural networks and building biologically-informed neural network models. He is a founding scientist of the Blue Brain Project at Ecole Polytechnique Federale De Lausanne (EPFL). He earned his PhD at the EPFL in computational neuroscience, where he developed data-driven modelling frameworks for biologically detailed digital models of neural networks. As a scientist of colour, Dr. Ramaswamy is passionately committed to promoting diversity, equity, and inclusion and is a founding member of the ALBA network, where he leads efforts to advance DEI in neuroscience, including launching the ALBA diversity podcast series in late 2020, highlighting the stories of emerging neuroscientists from underrepresented backgrounds.

![Panayotis Kevrekidis: Nonlinear Waves and their Applications (TSVP Talk at OIST)
Title: Nonlinear Waves and Their Applications: From Oceans to Planets, From Lasers to Quantum Fluids, From Origami to Pandemics
Speaker: Panayotis Kevrekidis, Distinguished University Professor, University of Massachusetts, Amherst
Abstract: In this talk, I will explore a number of ideas about nonlinear waves and their implications to a diverse array of fields: from mathematics to physics, engineering, computing, biology, and even (a little) art. I will begin with some history from 18th and 19th century fluid waves in channels and oceans, associated engineering observations, and artistic renderings. Next, I will share an intriguing story of (non) equity and inclusion around the first computer in post-atomic-bomb Los Alamos National Lab. The presentation will then pass through some Nobel Prize winning physical ideas related to the laser, quantum fluids, and some of their recent variations pursued experimentally including at Amherst. Finally, we will touch upon how in the past few years such wave phenomena have emerged in exotic materials, such as lattices made of origami elements, and how they have been leveraged toward studying the spread of pandemic infections.
Profile: Professor Kevrekidis studies a variety of systems stemming from the mathematical physics of nonlinear optical systems, of crystalline materials, as well as from the ultracold atomic setting of Bose-Einstein Condensates. The research mainly revolves around the existence, stability and dynamics of localized (solitary wave) structures in such one-, two- and three-dimensional setups, often described by equations of Nonlinear Schrodinger or Klein-Gordon type. Besides this main thrust of research Professor Kevrekidis also maintains a wide variety of additional modeling interests including mathematical biology [especially tumor angiogenesis, nephron dynamics and DNA models], simple cosmological models, the nucleation of liquid droplets, phase transition phenomena, catalytic chemistry and associated reaction-diffusion models, and dynamics and energy landscapes of glassy materials among others.
Kevrekidis is a Fellow of the American Physical Society (APS), of the American Mathematical Society (AMS) and of the Society for Industrial and Applied Mathematics (SIAM). He has been awarded an Honorary Doctorate from the University of Ioannina, Greece (2023), and has been elected in 2024 as a member of the European Academy for Sciences and the Arts (EASA).
