As a capstone to the bioengineering program at ��AV, senior students complete a team-based, two-semester design project developing solutions to real-world biomedical and/or clinical problems.

At the topping off ceremony for Fuse at Mason Square, Rebecca Schuetz, Gavin Smiga, Lana Hashem, Kirubel Tadesse, and Rasil Alamri presented their group’s project on a virtual reality-based physical rehabilitation system.

Tell us about your project.

Many people around the world need lower limb rehabilitation to regain function, including more than 101 million stroke patients and many athletic injury patients. Despite the vast number of people needing rehabilitation, only 36% of these patients complete their plans of care and achieve maximum results. Virtual reality has proven to be more effective at improving gait and balance in stroke and rehabilitation patients when compared to traditional therapy. VR also is considered to be more exciting and engaging for patients. While some virtual reality rehabilitation tools currently exist, they are often inaccessible due to size, cost, and complexity. Therefore, our goal is to create a portable, inexpensive, and engaging virtual reality lower-limb rehabilitation platform that can be set up in a range of locations and used by patients in their own homes to regain mobility, muscular strength, and balance.

What inspired you to select this topic?

As a team, we talked about our interests, strengths and weaknesses, and passions, and settled on this project. We all had a strong background in coding, and we loved the idea of using code and virtual reality in a way that would improve patient outcomes. Through our interviews with rehabilitation patients and physical therapists, we were inspired by the need to make rehabilitation more engaging.

What has been your greatest success thus far?

Our greatest success so far has been leveraging clinical information to engineer critical aspects of our virtual reality rehabilitation platform. Through interviews with a diverse group, including physical therapists and patients undergoing physical therapy for lower limb rehabilitation, we gathered invaluable insights. The information encompasses aspects such as initial patient assessments, patient monitoring metrics, exercise efficacy, range of motion requirements, patient engagement strategies, and challenges faced in physical therapy. Armed with this comprehensive data, we enhanced the design of virtual environments and refined the overall design, marking a pivotal success in our project.

What is one thing you’ve learned while working on this project that will be useful to you in the field?

One significant takeaway from working on this project is the importance of brainstorming and prototyping. We started with five different designs and continued to test to narrow down our options to one design that met all our requirements. In addition, we valued feedback from experts who have used this technology as it helps us understand the strengths and weaknesses that we should address in our project. This will be very useful in the bioengineering field since it requires lots of testing and prototyping to ensure that our product meets the specific user needs of our stakeholders.

How would dedicated research space, such as the plans for Fuse at Mason Square, help sustain your project?

Finding a space large enough to base our project and one that was secure and quiet enough to allow for an optimal development environment was one of our great challenges. We have repurposed a room that was intended for storage space. A dedicated research space would equip us with all the tools we truly need to have a successful final design, as well as a testing space. With Fuse at Mason Square in particular, the fact that it has been purpose-built for research and will provide a space for all departments to come together is very exciting. For instance, once we have developed our device, we could collaborate with kinesiology or Psychology Department researchers to conduct studies where we test the viability of our product and improve it further. Then, we could collaborate with the Costello College of Business on the possibility of bringing our product to market.

At Fuse topping out ceremony, student researchers predict malicious intent from drone flight patterns Sarah Holland Mon, 02/12/2024 - 09:54

With today’s use and demand for all-access video, small Uncrewed Aerial Vehicles (UAVs), colloquially known as drones, are commonplace tools in everything from defense contracting to filming backyard barbeques.

While useful technology, UAVs can pose a serious security risk. ��AV systems engineering and operations research undergraduates Dyar Aziz and Markus Garretson are working with professor Ali Raz to develop a methodology for inferring UAV intent based on sensor data.

Tell us about your project.

UAVs are becoming ubiquitous for commercial, defense, and hobbyist operations, but pose a serious security risk to various defense and state installations (such as airports and military bases). While sensors can provide detection and tracking information for UAVs, it is vital to infer any potential malicious intent of the UAV so that counter measures can be put in place in a timely manner.

Our project focuses on predicting the state and intent of UAVs from uncertain sensing data. This work shows how an inference engine for UAV state-estimation and intent can be built by exploiting sensing and tracking data from a multisensor installation, using state-of-the-art, high-level information fusion and systems engineering tools. We are applying model-based systems engineering techniques to simulate multisensor fusion and determine a UAV’s (specifically drones) movement and behavior.

What inspired you to select this topic?

We were introduced to the project by our former professor Raz and decided to work on it as we are both interested in aerospace.

What has been your greatest success thus far?

We have been able to develop multiples models and scenarios simulating both drones and real-world use cases of drone tracking such as a radar installment at an airport.

What is one thing you’ve learned while working on this project that will be useful to you in the field?

We have developed our knowledge and ability to apply model-based systems engineering (SysML), as well as building simulations in MATLAB. Additionally, we have learned about data fusion, fusion techniques, sensor types, and potential uses for them. Finally, we have been able to gain insight into the future of counter drone system development and high-level data fusion as it is at the cutting edge of technology.

How would dedicated research space, such as the plans for Fuse at Mason Square, help sustain your project?

A dedicated research space would enable us to collaborate amongst our team and with other teams with similar experience and knowledge, as well as with teams from other disciplines.

How nano roughness could smooth out clotting risks
September 5, 2024

Biography

Surfaces that contain micro- and nanoscale features in a well-controlled and “engineered” manner have been shown to significantly affect the cellular and subcellular function of various biological systems. Our research is focused on using the tools of micro- and nanotechnology for applications in biomaterials and tissue engineering. The goal of current research is to design implants that induce controlled, guided, and rapid healing in cardiovascular implants such as stents and heart valves; and orthopedic implants such as hip and knee joint implants. In addition to the acceleration of normal wound healing phenomena, these implants should result in the formation of a characteristic interfacial layer with adequate biomechanical properties.

To achieve these goals, however, a better understanding of events at the tissue-material interface is needed, as well as the development of new materials and approaches that promote biointegration. Our work proposes the use of well-controlled nanostructured interfaces to enhance implant integration. We hypothesize that controlled biomimetic nanoscale architectures can promote cell differentiation and matrix production and enhance short-term and long-term integration. Moreover, the ability to create model nano-dimensional constructs that mimic physiological systems can aid in studying complex tissue interactions in terms of cell communication, response to matrix geometry, and effect of external chemical stimuli. By understanding how physical surface parameters influence cells, we can more effectively design material surfaces that can be used in a clinical setting.

Born in Nha Trang, Vietnam, in 1945, Duong earned a Bachelor of Science in Economics and Law from the University of Saigon in 1966. She started her career working for the Ministry of Social Welfare before joining IBM in 1968, where she worked until she escaped from the communist government in 1975. She came to the United States with just $30 in her pocket.

Despite the challenges she faced as a refugee, Duong's belief in education, hard work, and family guided her. While still in a refugee camp, she secured employment with IBM through a representative at the camp. She moved to Northern Virginia and continued her work with IBM while raising seven nephews and nieces and pursuing multiple side jobs to make ends meet.

In 1994, Duong joined Pragmatics, where she currently serves as vice chairwoman and CFO. Over the past 30 years, she has overseen finance, legal, facilities management, and human resources departments, playing an instrumental role in the significant growth of the company.

In addition to her professional success, Duong has been active in philanthropy for over a decade. In 2011, she and her husband, Long Nguyen, donated $5 million to ��AV for what is now known as the Long and Kimmy Nguyen Building, and in 2015, she established the Kimmy Duong Foundation (KDF). The KDF supports a range of health, education, and welfare initiatives in the United States and Vietnam, and has established multiple scholarship programs with endowments of more than $4 million that administered by local universities.

Duong's commitment to philanthropy is evident through the KDF's scholarship program centered in the Washington, D.C., metropolitan area. The program has awarded 218 scholarships to date and plans to award 150 more in 2023. During the pandemic, the KDF started a program to support families dealing with economic hardship, which has benefited 160 families since 2020.

Through her philanthropic work, Duong aims to give back to the United States and Vietnam and to spread a message of service and gratitude to everyone she impacts. She believes that the investment of the United States in a refugee like her has been rewarded with a lasting legacy of good works, and she hopes to inspire others to pay it forward.

At a scholarship breakfast on campus this spring, Duong shared her story.

“Education is the cornerstone of life,” Duong told those in attendance, saying many in her generation worked multiple jobs to send their children to college. “Now, we are giving back.”

In 2019, as a sophomore, the electrical engineering major started a student club called the Inventors and Innovations Team (IIT) with one of his classmates, computer engineering major Nicholas Paschke.

“We wanted to give students an opportunity to build whatever it is that tickles their mind,” he said of the club that still meets in the makerspace at the Mason Innovation Exchange (MIX) in Horizon Hall on the Fairfax Campus. “As long as it's reasonable and innovative, we agreed to it and tried to create it. Since IIT started, our vision has been to have multiple teams working on building different projects at the same time.”

Current IIT projects include a fire-detecting drone that could help with wildfires and a sensing cane for the visually impaired. Some ideas will fail, but this doesn’t bother Gutala, who graduates with a bachelor of science this month. It is the ideas themselves and the execution that interest him.

As he approached his senior year, Gutala wanted to take things to the next level and founded the hardware hackathon, HackOverflow.

“Its purpose was all about giving students the hands-on opportunity to create something grand,” said Gutala, who recently served as the chair of HackOverflow’s executive committee and is now an advisor.

They partnered with an existing hackathon at Mason, Patriot Hacks, and Mason’s Institute of Digital Innovation's executive director Kammy Sanghera. The event took place in March 2022 at the MIX.

While many hackathons focus on coding, HackOverflow had students using the MIX’s 3D printer, soldering station, and other equipment to create prototypes of their ideas. Gutala said it is one of only a handful of hardware hackathons in the country.

“Throughout the process, Sai ensured that participants of HackOverflow had the resources and mentors to design prototypes,” said Sanghera. “From building his executive team to seeking sponsorships for the event, Sai was professional and diligent. Through initiatives like IIT and HackOverflow, Sai generated opportunities for his peers to change the world positively.”

Gutala has also started a company called Alphawave and has been one of the student entrepreneurs in the MIX’s incubator space. With Alphawave, Gutala is developing appearance-customizable apparel. He began with footwear—and he already has a prototype—but Gutala sees this as the beginning of using technology to customize personal items for self-expression.

Through the incubator program, Gutala was able to have his own space within the MIX and use of the program’s professional development resources, such as the mini Innovation Commercialization Assistance Program (ICAP) program offered to Mason student entrepreneurs. Gutala said he found the mini “the most helpful thing ever.”

“ICAP focuses on finding your ideal customer that will be loyal to your company,” said Gutala. “If a business can understand their customer, everything else is easy.”
