“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.

Seminar: Healthcare and the Environment: Emissions and Effects of Surgical Models and their Material Use @ 328 Malone Hall
Apr 20 @ 2:00 pm – 3:00 pm

Dr. Cassandra Thiel

Dr. Cassandra Thiel is a Fulbright-Nehru Fellow studying the lifecycle impacts of cataractsurgery at Aravind Eye Hospitalin Pondicherry, India. Dr.Thiel obtained her BS in Civil Engineering from Michigan Technological University in 2009 and completed her PhD in Civil Engineering from the University of Pittsburgh in 2013.




Healthcare and the Environment: Emissions and Effects of Surgical Models and their Material Use

The growing field of sustainability research endeavors to confront a fundamental challenge of our society- how  do we streamline our current consumption while simultaneously ensuring we can achieve our future requirements?In no area is this more evident than US healthcare. Spending on healthcare has reached nearly 18% of the USGDP. More


Seminar: Smart Technology-Enabled Building Energy and Peak Load Reduction and Their Effects on Occupants and the Indoor Environment @ Malone Hall room 107
May 27 @ 10:30 am – 11:30 am


Kristen Cetin is a PhD candidate at the University of Texas at Austin, in the Department of Civil, Architectural and Environmental Engineering, in the Building Energy and Environment Group. She is also a licensed professional engineer and a LEED professional. Her research focuses on the use smart grid-connected technologies to reduce building energy use and peak loads, and assessing their effects on building occupants and the indoor environment.




Building operations consume approximately 72% of electricity in the United States, and are responsible for over 70% of the peak demand on the electric grid, particularly in warm climates. The increasing deployment of technologies such as smart meters, home energy management systems (HEMS), and smart home-connected sensors and devices and their associated data provide an opportunity for data-driven operation and evaluation of the performance of buildings and their systems. This is particularly important as we face challenges in energy price fluctuations, distributed and renewable energy grid integration, and climate variability. More
