Graduate students

Md Sazzadur Rahman

Sazzad completed his undergraduate studies from Bangladesh University of Engineering and Technology (BUET) in EEE department. Before joining Roy Lab, he conducted research on photovoltaic devices and nanostructures. Now his research focuses are optoelectronic and electronic neuromorphic devices.

He has a keen interest on traveling, hiking, fitness, amateur photography, listening to music and watching thought-provoking movies. One of his unique attributes is he has a movie archive from over 110 countries around the world. He loves coffee and will never refuse a cup ever, even at midnight!




Jiazheng Chen

Jiazheng Joined Roy Lab in 2023. He earned his Bachelor’s degree at Central South University in 2021 and then furthered his studies at the University of Pennsylvania, obtaining his Master’s degree in 2023. His primary research interest is in the realm of nanoelectronic devices. Outside the lab, he is a fervent sports enthusiast.







Xudong Zhuang

Xudong was born in Xiamen, China, and received his bachelor’s degree at Huazhong University of Science and Technology (HUST) in 2020, majoring in energy and power engineering. During his undergrad period, he worked on atomistic modeling and simulation for hydrogen energy storage materials. He then obtained his first master’s degree in mechanical engineering at the Hong Kong University of Science and Technology, during which he started to explore other fields of interest. Once he graduated from the first master’s degree, he decided to shift to the field of nanoelectronics and obtained his second master’s degree in materials science and engineering at Northwestern University in 2022, where he worked on neuromorphic computing devices, crossbar arrays, and algorithm showcasing. During this period of time, he obtained various skills, including materials synthesis, device fabrication and characterization, device modeling, and algorithm development. At Roy Lab, he will continue his exploration of neuromorphic/in-memory computing, particularly focusing on devices and circuits for energy-efficient AI acceleration.

Besides his scientific work, he has been a serious French horn player for ten years and served as the principal horn of his high school symphony orchestra and HUST symphony orchestra. He still serves on the advisory board of his high school symphony orchestra, where he provides musical instructions with a particular focus on the brass section when needed.  Additionally, he is a gym guy working on strengthening his body and a basketball player trying to improve his shooting skills.


 Dylan Matthews

Dylan was born on Long Island, NY and completed his bachelors degree in Electrical Engineering at the University of Notre Dame in 2024. His interests are in nanoelectronic device operation and fabrication.

Outside the lab he enjoys chess, fitness, skiing and soccer.






Bingyu Zhang

Bingyu was born in Shandong, China and earned her EE bachelor’s degree from Shandong University in 2022. After that, she became a Gator at the University of Florida, completing her master’s degree of ECE in 2024. Her primary interest is in devices with wide band gap materials, such as Ga2O3 and GaN.

She enjoys cooking and hanging out with friends. She is also a 100% cat person and has a lovely calico cat named ‘Jade Ice’.



Xianduo “Jerry” Zhao

Jerry completed his undergraduate studies in ECE at Vanderbilt University in 2024. Before joining Roy Lab, Jerry’s research involves the study of radiation effects of wide bandgap devices such as SiC and GaN.  Outside the lab, Jerry loves to travel, cook, and play golf.







Undergraduate students

Broden Murray

Broden is an upperclassman in the Digital Systems concentration of the Electrical and Computer Engineering + Computer Science program at Duke, with a minor in score-focused music. He’s enjoyed programming since middle school, but his drive to uncover abstraction led him to hardware design. His professional dream is to design microarchitectures or beyond-CMOS transistor devices.
Classically trained in violin as a child, he was moved to apply an engineering spirit to music theory and fiddling with music production. And, being from California, he has a deep love for the nature of the Western U.S. He is also big on running and lifting. Ask him about his playlists.


Isaiah Bernardino

Isaiah is an upperclassman studying Electrical and Computer Engineering with a Concentration in Machine Learning at Duke. Being from Silicon Valley, he hopes to move back and pursue a career in the semiconductor industry. In his free time, he enjoys playing pickup basketball, learning songs on the guitar, and cooking with friends and family. A fun fact about Isaiah is that he lived in Germany for almost 3 years, so he can speak German and has travelled all around Europe.



Austin Harrison

Austin is an upperclassman interested in devices and electromagnetics as a student of the Electrical and Computer Engineering + Computer Science program at Duke. He has a deep interest in physics and the underlying mechanisms by which the electrical world is built. Austin is an avid NFL fan (of the best team in football, the Baltimore Ravens), and he also loves to play lacrosse and lift weights with his friends. Along with some friends, he restarted and serves as Vice President of Duke’s IEEE Student Branch.


Dinuk DeSilva (Summer REU)

Dinuk is studying electrical engineering at Georgia Tech with concentrations in devices and robotics. He is also pursuing a computing and intelligence minor.

In his free time he likes to play soccer and go to the gym.



Marino Santos (Summer REU)

Marino is pursuing a double degree in electrical engineering and physics at the University of Texas at Dallas. He has previously conducted research in ferroelectric memory devices where he gained skills in electrical characterization, device fabrication, and data analysis. Following graduation, he is seeking a Ph.D. in electrical engineering.

Outside of school, he enjoys traveling, playing tennis, studying mathematical models and new languages.
