MEAM Seminar: “A Multi-Scale Homogenization Model for the Viscoplastic Response of Polar and Sea Ice”

Moore 216 200 S. 33rd Street, Philadelphia, PA, United States

The rheology of polar ice evolves in response to weather and climate changes, by modifying its microstructure. While the experimental evidence for the dependence of rheological properties on the microstructure is well documented, there are only a few modeling efforts to capture the rheological behavior of polar ice, mostly by fitting continuum models to the […]

MEAM Seminar: “Recent Evolution of Climate Science: From Greenhouse Gases and Temperature to Aerosol Particles and Precipitation”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

On the eve of the Intergovermental Panel on Climate Change (IPCC) Sixth Assessment Report, I will present a brief overview of how climate science has evolved since the publication of the Charney Report in 1979, and use a few examples from my recent work to show how one can use numerical models, observations and theories […]

Doctoral Dissertation Defense: “Machine Learning for Robot Motion Planning”

Robot motion planning is a field that encompasses many different problems and algorithms. From the traditional piano mover's problem to more complicated kinodynamic planning problems, motion planning requires a broad breadth of human expertise and time to design well functioning algorithms. A traditional motion planning pipeline consists of modeling a system and then designing a […]
