Alan Garfinkel
Alan Garfinkel is Professor at the University of California, Los Angeles in the departments of Medicine (Cardiology) and Integrative Biology and Physiology. His research work applies nonlinear dynamics to cardiac arrhythmias and to the creation of biological patterns in space and time. As a teacher, he created a new course to teach dynamics and modeling to biology students, with no “calculus”  prerequisite. Early life and education 
Alan Garfinkel was born in Brooklyn, New York. After attending public schools in New York City, he graduated from Cornell University in 1966 with a degree in Mathematics and Philosophy. After two years at MIT, he moved to Harvard University, where he earned a doctorate in philosophy in 1975. Research and career 
In Garfinkel's PhD dissertation, written under Hilary Putnam, which Yale University Press published as Forms of Explanation, he proposed the notion of Contrastive Explanation, that an answer to the question “Why X?” is really an answer to “Why X rather than a limited set of alternatives to it?”. He became a cardiac researcher and modeler, and he and his team identified mathematical (deterministic) chaos in a real rabbit cardiac arrhythmia, then used “chaos control” techniques to stabilize the arrhythmia into periodic beating. Using analytical techniques from nonlinear dynamics, he and his colleagues Zhilin Qu and James N Weiss then demonstrated that Ventricular Fibrillation (VF), the primary cause of Sudden Cardiac Death, is an example of deterministic spatiotemporal chaos, and devised and experimentally verified a mechanism to prevent VF. His research interests include the electrophysiology of cells and tissues modeled mathematically, analysis of experimental and clinical arrhythmia data with techniques of nonlinear dynamics, and research and development of pharmacologic and electrophysiological therapies to prevent or regulate arrhythmias. He also studies the role of physiological and pathophysiological oscillations in biological systems, with a particular focus on the mechanisms of their creation and destruction, and the creation of normal and pathological patterns in biological systems. He started his career as a professor of the philosophy of science at California State University, Northridge. Moving to the University of California, Los Angeles, he held  a succession of positions leading to Professor of Medicine (Cardiology) and Integrative Biology and Physiology (2003–2018), where he is currently Research Professor  and Professor Emeritus. In 2019–2020, he was Newton Abraham Visiting  in the Department of Computer Science and Lincoln College, University of Oxford. Awards and honors 
Garfinkel has received awards including Astor Visiting Lecturer, University of Oxford, UCLA University Distinguished Teaching Award (2015) and many others. His text “Modeling Life” was awarded the Textbook Excellence Award of the Textbook and Academic Authors Association. His patents include “Real time stabilizing system for pulsating activity” (US5447520A). Books
