“Modeling Public Health and Medicine: STScI Engineering & Technology” Colloquium @ John Bahcall Auditorium, Space Telescope Science Institute, Muller Building, San Martin Drive
Apr 2 @ 3:00 pm – 4:00 pm

Systems dynamics and agent-based modeling have recently been used to explore complex systems in a wide range of disciplines. This talk will begin with a quick tutorial outlining the basic principles of these computational tools. Several simulations will be shown to demonstrate the visual aspects of the methods. A few current research applications in public health and medicine at Johns Hopkins will also be described. The talk will conclude with a brief, apolitical analysis of sequestration.

Tak Igusa is the founding Director for Education and Research of the Johns Hopkins Systems Institute. He received an A.B. in Applied Mathematics at Harvard and a Ph.D. in Civil Engineering at Berkeley and was on the faculty at Northwestern University before returning to Baltimore in 1999 as a professor at Johns Hopkins. His research interests are in the application of mathematical modeling to understanding systems in public health, civil infrastructure, and medicine. His interests also include structural dynamics, acoustics, and applications of statistics and probability theory to problems in civil and mechanical engineering, and more recently in atmospheric science.

Tea & Cookies will be served at 2:45 pm

Workshop on Systems Methods for Understanding Obesity
Apr 10 @ 12:00 pm – Apr 11 @ 6:00 pm

The Education and Training Core (ETC) of the Johns Hopkins Global Center on Childhood Obesity (JHGCCO) is pleased to announce a training workshop entitled Agent-based and System Dynamics Models: New Tools for UnderstandingObesity. The workshop will begin at noon on Wednesday, April 10, and run until 6 pm on Thursday, April 11, with a dinner and reception on Wednesday night.

The workshop is intended for researchers, program staff, students, trainees, faculty and those with an interest in learning about how agent-based (ABM) and system dynamics (SD) models can be used to gain insights into the causes of, and potential solutions for, the obesity epidemic. The primary faculty for this workshop include Prof. Tak Igusa from the Johns Hopkins Systems Institute and the Whiting School of Engineering, and Prof. Thomas Glass from the Johns Hopkins Bloomberg School of Public Health. There will also be an invited lecture and discussion by Dr. Amy Auchincloss, Ph.D., MPH, Assistant Professor of Epidemiology and Biostatistics from Drexel University.

Systems Life Cycle Design Approach to Green Design and Energy Sustainability (abstract)
Emerging interest in the renewable energy sources has garnered new contributions in energy systems engineering. Designing renewable energy generation systems, however, brings additional layer of challenges in that it is impossible to assess and predict exogenous conditions accurately. Hybrid power generation systems (HPGS), with respect to this challenge, can bring a new level of technical and economic performance of power supply by mitigating the effect of uncertainties. Kim’s team recently developed a new suite of systems design methodologies for single HPGS and hybrid energy farms that overcome non-smooth logical disjunction by use of multidisciplinary design optimization with complementarity constraints and various risk and reliability measures. The methods also utilize multi-stage programming model and design analytics capabilities for predicting system behavior in the near future time horizon. In this presentation, the speaker will present the findings from the recent studies sponsored by NSF and industrial partners (Caterpillar and Deere) in collaboration with the National Renewable Energy Lab (NREL) and introduce newly emerging topics in renewable energy systems engineering.
