Prof. Ying Li is in a selected small group of researchers that have received the prestigious Young Investigator Award from the Air Force Office of Scientific Research (AFOSR).
His award will support de novo design of thermosetting polymers with deep reinforcement learning, and will provide new capabilities needed to avoid the traditionally used trial and error approaches and perform rational design to discover novel, yet predictable combinations of properties for cutting-edge thermosetting polymers.
This past January, the University of Connecticut School of Engineering held the Women in STEM Frontiers in Research Expo (WiSFiRE), which brought together and celebrated some of the important research and journeys of female faculty in the School of Engineering. The conference was co-organized by our own Prof. Anna Tarakanova.
Prof. Thanh Nguyen receives the highly regarded ACell Young Investigator Faculty Award at the 2020 Regenerative Medicine Workshop, which brings together leading experts from across the expansive field of regenerative medicine. Prof. Nguyen will deliver a keynote speech along with other world renowned researchers in the field of regenerative medicine during the event, which will take place at the Wild Dune Resort, South Carolina, in March 2020.
Prof. Thanh Nguyen’s research group has reported on the first biodegradable ultrasonic transducer that can help medication move from blood vessels into brain tissues and circumvent the body’s traditional defense mechanisms.The work is published in the journal of PNAS (Proceeding of National Academy of Science) (Dec 2019), and the two first authors of this paper are PhD students in Nguyen lab, namely Thinh Le and Eli Curry.
A PLLA piezoelectric nanofiber film (left) to generate an acoustic wave (middle) that can open the blood-brain barrier (BBB) (right) to deliver medicines into the brain tissue.
When implanted into the brain, this novel device can generate ultrasonic waves for buzzing drugs through the blood-brain barrier (BBB) to treat brain diseases (e.g. cancers), and then self-vanish, avoiding the need of invasive removal surgery that is often required for conventional medical implants. More details can be found in the UConn Today article.

Art and science are two fields that appear to be worlds apart at first glance, but according to George Matheou, assistant professor of mechanical engineering, the intersection between the two are actually extremely important. This notion became the inspiration behind his art exhibit called Fluid Dynamics in Art and Nature at the William Benton Museum of Art.
During the 45th Annual Design Automation Conference, held by the American Society of Mechanical Engineers (ASME) this past summer, Mechanical Engineering Professor Julián Norato has been awarded the prestigious Design Automation Young Investigator Award.
Prof. Norato receiving the award from Prof. Chris Mattson on behalf of the Design Automation Committee
This award is given once each year “to recognize an outstanding young investigator who is making noteworthy contributions in the area of design automation, including research in design representation, design optimization, design evaluation, and/or design integration.” The award was presented at the ASME’s Design Automation Conference, which was held on August 18-21, 2019 in Anaheim, California. This conference brings together every year international experts in the field of design automation.
Norato was given this award based on the work and research he has done in topology optimization. Topology optimization is a computational methodology to automatically design parts to maximize structural strength with minimal amounts of material in the most efficient and effective way. A major focus of Norato’s research group is to do the topology optimization employing exclusively certain shapes, like bars or plates, that make manufacturing with conventional processes easier.
An example of the work Norato does with topology optimization
Prof. Christopher Mattson presented the award to Prof. Norato “in recognition of his expertise in topology optimization, specifically his advances in stress-based topology optimization and development of the geometry projection method” and to “recognize his continuous and dedicated service to the Design Automation Conference and his outreach to the community.”
