The Department of Chemical and Biological Engineering will host Arvind Ramanathan, staff scientist at Argonne and senior scientist in the Consortium for Advanced Science and Engineering at the University of �鶹APP, for a seminar titled, “On Foundation Models and Autonomous Discovery for Biological Systems Engineering: Peptides, Proteins, Pathways, and Beyond” on Wednesday, March 8, 2023, in Room 131 of Perlstein Hall from 3:15–4:30 p.m.

Abstract
Engineering biological systems to precise specifications can be a daunting task—one that requires the ability to tackle vast design spaces emerging from the diversity in the biophysical and biochemical mechanisms and one that also requires certain ingenuity in understanding the genetic basis of how such mechanisms emerge. In this talk, I will outline a paradigm where we posit that autonomous discovery (i.e., automated labs that are “managed” and “run” using artificial intelligence techniques) can vastly benefit biological design applications. Further, to tackle the complexity of biological design, we argue that a specific class of AI techniques, namely foundation models—unsupervised learning techniques that can summarize vast troves of rich biological data—can outperform classical techniques. We illustrate this paradigm of using foundation models and autonomous discovery on three exemplar applications: (1) designing antimicrobial peptides using generative models; (2) engineering proteins using genome-scale language models; and (3) understanding the basis of how SARS-CoV-2 may evolve into new variants of concern. Our work demonstrates that AI-based generative models and autonomous discovery holds much promise for how we can engineer novel biological systems. We also articulate challenges that emerge from integrating diverse robotic platforms within the context of autonomous discovery and discuss how these challenges can be overcome.

Biography
Arvind Ramanathan is a staff scientist in the Data Science and Learning Division at Argonne, and is a senior scientist within the Consortium for Advanced Science and Engineering at the University of �鶹APP. His group works in the area of integrating diverse experimental observations with computational simulations using scalable artificial intelligence approaches for drug discovery in infectious diseases and in cancer. He is currently engaged in developing the autonomous laboratory applications at Argonne focused on understanding how disordered peptides can undergo controlled phase separation and how one can design such peptides based on AI techniques. His group was recently awarded the Institute of Electrical and Electronics Engineers and Association for Computing Machinery’s Gordon Bell Prize for high performance computing applications in COVID-19 research (2020, 2022). In addition, he is also recognized with Battelle’s Early Career Researcher Award (2017).
