Faculty News

Dr. Li

Dr. Zhenyu Li (BME) has received a one year, $151,525 research grant from Johnson & Johnson Vision for “Microfluidic Devices for Evaluating Tear Deposition on Contact Lenses.” Biomolecules in tears such as lipids and proteins can interact with contact lenses and form deposits, which may cause discomfort, inflammation, and even corneal damage. However due to the small volumes of tears, no instrument exists that can study the interactions of real human tears with contact lens materials in a quantitative and reproducible manner. This project aims to use microfluidics technology to build a tear analysis platform capable of quantifying the molecular depositions on contact lens.

Dr. Zaghloul

On November 27, the US Patent and Trademark Office granted Dr. Mona Zaghloul (ECE) US Patent #10139382 for “Device having an array of sensors on a single chip.” The abstract for the patent reads: “A nanostructure sensing device comprises a semiconductor nanostructure having an outer surface, and at least one of metal or metal-oxide nanoparticle clusters functionalizing the outer surface of the nanostructure and forming a photoconductive nanostructure/nanocluster hybrid sensor enabling light-assisted sensing of a target analyte.”

Entrepreneurship News & Events
New SEAS Course: Social Impact Design Thinking
SEAS 4800.80 (CRN: 48682)/SEAS 6800.80 (CRN: 48683)
Spring 2019: Tuesdays 6:10 – 8:40 pm
SEH, 1450
Innovation starts with humans. Join an interdisciplinary social impact innovation class that puts human experience at the forefront of problem-solving and triple bottom line venture creation. Design thinking and human centered design are proven and repeatable problem solving methodologies that any discipline, profession, business, or social venture can employ to create social impact and value and achieve results. Interdisciplinary student teams apply design thinking to local challenges they research ethnographically, while facilitating partnerships with public and private Washington DC-based organizations. This class is a first of it its kind at GW in combining social innovation, design thinking, gear up, and business model creation.


GW is now offering a new interdisciplinary minor in creativity, innovation and entrepreneurship. The minor will give full-time, undergraduate students an opportunity to explore and integrate programs/courses from SEAS, CCAS, and ESIA. The choice of two field electives allows students to tailor the minor to match their interests in creativity, fine arts, design, media, environment, social impact, health care, and/or technology. Students may add this minor to their degree by bringing the minor form to their home school advising office.
