Faculty invited to President's Colloquia presentation on Wednesday

Faculty members are encouraged to attend the next President's Colloquia presentation, set for Wednesday (Oct. 17). Hosted by President Mitch Daniels, the colloquia provide opportunities to hear faculty experts discuss their research in presentations specifically for non-experts.

The fall 2018 faculty colloquia are scheduled for 4-6 p.m. at Westwood, the president's home. Access to Westwood is from the north via McCormick Road, which is scheduled to be closed from just south of Westwood to Third Street through November. The roundabout at McCormick and Stadium Avenue is open.

To register for the colloquia or to find out more information, visit the President’s Colloquia webpage.

David Whittinghill, associate professor of computer graphics technology and computer and information technology, on “Virtual Reality’s Simulator Sickness Problem: Where We Are Today” 

Simulator sickness is a phenomenon experienced in virtual reality applications that causes users to experience an intense sensation of vertigo and, in extreme cases, nausea. The simulator sickness problem is multidimensional and complex, having roots in technology, psychology and physiology. At present, a reliable, inexpensive and nonintrusive treatment has yet to be found. Despite the combined efforts of not only the research community but several of the largest technology companies in the world — who have a strong market incentive to be the first to market with a solution — a solution remains elusive.

In this talk, Whittinghill will discuss the science of simulator sickness in depth to help shed light on this stubborn usability problem. He will summarize and evaluate existing attempts to address the issue, as well as his own research, according to their respective strengths and weaknesses.

Vilas Pol, associate professor of chemical engineering, on “The Quest for Safer Rechargeable Batteries”

The ViPER (Vilas Pol Energy Research) laboratory focuses on the development of high-capacity electrode materials, their engineering for longer cycle life and improved safety. Considering the advantages and limitations of known synthesis techniques, a solventless, single-step processing technology has been developed to fabricate a variety of unique anode and cathode materials for Li-ion, Na-ion, K-ion and Li-S batteries.

Pol’s talk also will discuss how tailored spherical, solid, dense carbon-particle anodes could make Li-ion batteries safer by distributing current uniformly during charging, minimizing excess solid-electrolyte interphase (SEI) formation and dendritic growth. He also will demonstrate ViPER’s recent efforts on structural, morphological, compositional and electrochemical properties of various fascinating electro-chemistries. Additionally, he will discuss ViPER’s determinations on the transformative science, engineering and technology.
