Dragonfly Larvae Inspire New Designs for Prosthetic Heart Valves
Professor Mory Gharib and postdoctoral researcher Chris Roh (MS '13, PhD '17) have studied the design and control of the jets that dragonfly larvae use to propel themselves to re-design health values. "The current heart valve design is a one-size-fits-all, where no patient-specific design is considered, and this causes many post-transplant complications," Dr. Roh says. "We believe that an intentionally off-centered opening of the heart valve to more closely match the patient's original blood flow will be an important design parameter that can be adjusted based on each patient's heart morphology."

Winners of the 2018 Demetriades - Tsafka - Kokkalis Prizes Announced
The student winners of the 2018 Demetriades - Tsafka - Kokkalis Prizes were announced at the end of this academic year. Claire Bedbrook, advised by Professors Frances H. Arnold and Viviana Gradinaru received the prize in Biotechnology. Her research is in engineering proteins capable of controlling and reading out neural activity to advance neuroscience research. Nicholas Dou, advised by Professor Austin Minnich received the prize in Nanotechnology. Nicholas focuses on developing and characterizing novel nano-architected materials that are exceptionally lightweight, mechanically resilient, and thermally insulating. Xiaoqi Ren, advised by Professor Adam Wierman received the prize in Environmentally Benign Renewable Energy Sources. Xiaoqi’s research is focused on optimization of today's large-scale data centers, including online scheduling, energy usage and sustainability, and new market mechanisms for electricity markets and data clouds. Daniel C. Bowden, advised by Professors Joann M. Stock and Victor Tsai has received the prize in Seismo-Engineering, Prediction, and Protection. Daniel has worked on a range of projects relating to the propagation of seismic waves in the Earth's crust. Colin Cook, advised by Professor Yu-Chong Tai has receive the prize in Entrepreneurship. Colin is working on a phototherapeutic contact lens to treat diabetic retinopathy, a leading cause of blindness.
Richard B. Chapman Memorial Awards
Morgane Anne Marie Grivel advised by Professor Morteza Gharib, Kazuki Maeda advised Professor Tim Colonius, and Jason Schlup advised by Professor Guillaume Blanquart are recipients of the 2018 Richard B. Chapman Memorial Award. Morgane's research focuses on using hydrophilic and hydrophobic regions to modify hydrodynamic flows. Jason's research utilized computational fluid dynamics to investigate the highly unstable combustion of hydrogen-air mixtures with a focus on accurate, cost-effective modeling techniques. Kazuki does research in multi-phase flow, computational fluid dynamics, and biomedical engineering. The Richard B. Chapman Memorial Award is given to an EAS graduate student in hydrodynamics who has distinguished himself or herself in research.
