Physics Seminar: Grad School Panel
Two recent alums who are studying at the U of MN will be joined by a senior physics major. They will talk about their experiences and answer questions about grad school.
Elliot Schmidt ’12, Lauren Snyder ’12 & Lucas Sletten ’15

Joint Neuroscience and MSCS Seminar:
Breaking the Speech Code: A Neuroinformatic Approach
Chris Boven, UIUC
Neurophysiologists have long relied on a standard set of visualization and statistical techniques for the analysis of neural spike trains. With the rise of so-called machine learning algorithms and the availability of more powerful hardware, new approaches tothis problem are being explored which have the potential to enhance our understanding of speech and the auditory system.

7:00 pm, RNS 290 – Speaker: Claudia Neuhauser, University of Minnesota
The Role of Big and Small Data in the Life and Health Sciences: Big and small data are ubiquitous in the life and health sciences: We use genomics data to diagnose and treat diseases, sensor data to measure physiological variables, satellite data to track land use changes.To generate the data, we develop novel technologies. The data are probed with a variety of computational tools. Mathematical models are used to uncover mechanisms and make predictions. Mathematics and statistics provide the foundation for the models and tools. They are also a way of thinking. We will discuss a number of application areas to illustrate how mathematics and statistics play an important role in gaining a greater understanding in these various applications. Furthermore, we will discuss the importance of communicating the knowledge extracted from the data and will introduce some principles from design to facilitate communication.

Boolean Approximations of Differential Equations Models that Capture Bistability
Boolean Notwork (BN) and Finite Dynamical System (FDS) models of complex biological interactions have recently emerged as viable companions to differential equations (DE) models. Unlike DE models, FDS models do not require detailed knowledge and information about the reaction kinetics of the system. This makes them better suited in the modeling of large biological networks where many important details about the individual interactions and reactions may be unknown. FDS models provide “coarse-grained” approximations of the system’s dynamics and are qualitative in nature. Thus, it is not immediately clear whether such models are capable of capturing the multi-stability behavior exhibited by many biological systems, a feature that would generally depend on the specific values of the model parameters. The talk will present some background on FDS models, then use the lactose (lac) operon in E. coli as a model system to introduce BN approximations of delayed DE models. The focus will be on the ability of BN models to capture the well-known bi-stability behavior of the lac operon.
