APPPHYS 229: Statistical Mechanics of Learning and Computation
Recent years have witnessed the successful application of time-honored techniques from the statistical physics of disordered systems, like the replica method and the cavity method, to understanding modern advances in machine learning and computation. We will develop the foundations of these methods, starting with a crash course in statistical mechanics, and then progressing to the basic theory of spin glasses, associative memories, random matrices, and random landscapes. We will additionally learn how to apply this theory to problems in learning and computation, including high dimensional statistics and deep learning. Overall, this foundations course will prepare students to read the growing interdisciplinary literature spanning physics, learning and computation.

APPPHYS 235: Biotransport Phenomena (BIOE 235, BIOPHYS 235, ME 235)
The efficient transport of energy, mass, and momentum is essential to the normal function of living systems. Changes in these processes often result in pathological conditions. Transport phenomena are also critical to the design of instrumentation for medical applications and biotechnology. The course aims to introduce the integrated study of transport processes and their biological applications. It covers the fundamental driving forces for transport in biological systems and the biophysics across multiple length scales (molecules, cells, tissues, organs, whole organisms). Topics include chemical gradients, electrical interactions, fluid flow, mass transport. Pre-requisites: Calculus, MATLAB, basic fluid mechanics, heat transfer, solid mechanics.

APPPHYS 237: Quantitative Evolutionary Dynamics and Genomics (BIO 251)
The genomics revolution has fueled a renewed push to model evolutionary processes in quantitative terms. This course will provide an introduction to quantitative evolutionary modeling through the lens of statistical physics. Topics will range from the foundations of theoretical population genetics to experimental evolution of laboratory microbes. Course work will involve a mixture of pencil-and-paper math, writing basic computer simulations, and downloading and manipulating DNA sequence data from published datasets. This course is intended for upper level physics and math students with no biology background, as well as biology students who are comfortable with differential equations and probability.
