Exploring Frontiers: Predicting Biology Webinar
Model systems have been used to successfully pioneer foundational research, leading not only to an advanced understanding of biological systems but also to translational breakthroughs. However, only a portion of scientific results seen in mice are mirrored in humans. How can we better infer which observations will hold true in both systems?
Join us as we highlight innovative approaches addressing this frontier challenge. The webinar will include speaker presentations and a lively panel discussion on the challenges, opportunities and next steps needed to move the needle in modeling mouse to human inference. See below for the agenda and speaker information.

Douglas Brubaker, Ph.D.
"Computational humanization of latent variables for cross-species modeling"
Abstract: Direct mapping of molecular-to-phenotype relationships across species often fails to yield translatable insights into disease pathobiology, therapeutic mechanisms, and rules of life. To address this challenge, systems biology methods have been proposed to enhance the predictive capability of model organisms and in vitro systems. Our approach to these challenges, termed computational humanization, aims to translate models of animal data to humans via computational integration of animal and human-context measurements. In this talk I will discuss our work developing latent variable methods for cross-species modeling and ongoing efforts to better translate these models to heterogeneous human populations.
Bio: Douglas Brubaker is an Assistant Professor in the Weldon School of Biomedical Engineering and Core Faculty Member in the Regenstrief Center for Healthcare Engineering at Purdue University. His lab develops systems biology approaches to understand mechanisms of host-microbiome interactions and approaches to translate biological observations from model systems to humans. His research is supported by Open Philanthropy and the National Science Foundation. Professor Brubaker completed post-doctoral studies in the Department of Biological Engineering at MIT and holds a Ph.D. in Systems Biology and Bioinformatics from Case Western Reserve University.

"The mouse ascending: Translating human genetic variation to function"
Abstract: Inbred mice have been only modestly successful in modelling widely divergent clinical outcomes in human disease, due to their limited genetic background. As host genetics plays a significant role in disease susceptibility, pathogenic infection and treatment success, preclinical models that reflect human genetic variation are crucial for predicting disease course and developing precision therapies.Interbred panels of mouse strains offer allelic diversity that mimics human genetic variation with the requisite statistical power and resolution for dissecting complex traits. Mouse diversity resources combined with gene editing offer exciting prospects for creating a future of predictive biology for individualized disease prevention and treatment.
Bio: Nadia Rosenthal is Scientific Director of The Jackson Laboratory in Bar Harbor, Maine. She obtained her PhD from Harvard Medical School, where she later directed a biomedical research laboratory, then headed the European Molecular Biology Laboratory (EMBL) campus in Rome. She founded EMBL Australia as its Scientific Head, and was Founding Director of the Australian Regenerative Medicine Institute in Melbourne. She is an EMBO member, a Fellow of the UK Academy of Medical Sciences and of the Australian Academy of Health and Medical Science. She also holds a Chair in Cardiovascular Science at Imperial College London.
Rosenthal’s research team focuses on the role of growth factors, stromal cells and the immune system in the resolution of tissue injury for applications in regenerative medicine. They have recently shown how modifying the profile of immune cell infiltration can facilitate or prevent tissue repair and have demonstrated the power of harnessing mouse genetic diversity to identify new genetic pathways in the varied response to cardiovascular disease. Over the past year, they have turned their expertise in mouse genetics toward creating more precise mouse models for SARS-CoV-2.

"Found in translation: Leveraging machine learning models to bridge the cross-species"
Abstract: Mice are the most widely used and cost-effective model to study human diseases. Yet, from a clinical perspective, successful therapeutic experiments in mice often fail in human clinical trials. Despite the considerable time and expense involved, efforts to improve human-disease modeling have focused on developing mice that more closely mimic human biology. In contrast, there have been scarce attempts to develop in silico methodologies for overcoming translational challenge and this is despite an explosion of data.
Here we present Found in Translation (FIT), a data-driven machine learning model that, given a mouse gene expression experiment and a corpus of prior data comparing mouse/human experiments, predicts the biology in the mouse model relevant to the analogous human condition. FIT can increase identification of human relevant genes by up to 50%. The use of computational modeling to bridge the cross-species gap can reduce risk, save time and improve utilization of pre-clinical models.
Bio: Shai Shen-Orr is an Associate Prof. at the Faculty of Medicine at the Technion – Israel Institute of Technology, where he heads the Systems Immunology & Precision Medicine laboratory since 2012. His research is focused on charting the immune system landscape – namely the principles by which the immune system varies over time as a function of environment and genetics. For this, his lab develops novel computational methodologies, empowering human immune monitoring for precision medicine.
Prof. Shen-Orr received a BSc from the Technion in Information Systems (1999), an M.Sc. in Bioinformatics at the Weizmann Institute of Science (2002), a Ph.D. from Harvard University in Biochemistry (2007) and performed his postdoctoral studies at Stanford University with Prof. Mark Davis and Prof. Atul Butte.
Prof. Shen-Orr is also the Chief Scientist of CytoReason. CytoReason is building a machine learning model of the immune system; which it applies to drug development.
