Principal Investigator

Jeffrey Moran, Ph.D.

Assistant Professor of Mechanical Engineering, George Mason University

My research interests lie in understanding and using micro-scale thermal-fluid transport phenomena to enable new solutions to fundamental challenges facing humanity, including sustainable energy, environmental remediation, and cancer treatment. My doctoral work helped explain the physical mechanism for the self-propulsion of “catalytic micromotors,” which are micrometer-size metallic rods (50 times smaller than the width of a human hair) that can “swim” and carry cargo through liquids. My group studies active colloids at both the fundamental and applied levels, with the belief that a deep understanding of their inner workings will enable rational design for applications in efficient water treatment and delivery of therapeutics to hard-to-reach locations.

Outside of research, I am a freelance jazz musician, having played double bass for over 20 years. You can find me gigging around northern Virginia (bars, restaurants, other venues, etc.) a few times a month.

Postdoctoral Scholar

Amit Kumar Singh, Ph.D.

Postdoctoral Scholar, Department of Mechanical Engineering, George Mason University

My current research work is focused on development of nanobot-based treatments for pulmonary fibrosis. Before joining the George Mason University, I was a Senior Research Fellow for two years at the The Centre for Excellence In Nanoelectronics & Theranostic Devices (CENTD), Indian Institute of Technology Guwahati, India. I worked on synthesis of biomedical microrobots for anti-cancer therapy. I received my Ph.D. from the Indian Institute of Technology, Guwahati.

Ph.D. Students

Sajad Kargar

Ph.D. Student, Department of Mechanical Engineering, George Mason University

My research focuses on developing efficient cooling methods to reduce the carbon footprint and energy consumption of data centers, which currently consume about 2% of the world’s electricity. By incorporating hybrid methods combining liquid and air cooling, including free cooling and evaporative cooling, I aim to minimize energy usage and environmental impact. I also explore advanced liquid cooling systems enhanced by self-propelled nano/micro particles. I was awarded the prestigious Presidential Scholarship in Mechanical Engineering, recognizing my prior achievements and dedication to enrolling at GMU, which supports my full four-year program. Before joining GMU, I earned a Master of Science in Mechanical Engineering from Sharif University of Technology, Iran’s premier engineering school.

Outside of research, I enjoy reading books, camping, playing soccer, and playing violin.

Kushal Baraily

Ph.D. Student, Department of Biology, George Mason University (co-advised by Prof. Monique van Hoek)

My research is centered around biofilm disruption, where I explore the potential of self-propelled nanoparticles. By harnessing the unique capabilities of these nanoparticles, I aim to penetrate biofilms effectively and deliver antimicrobial cargo with precision. This approach holds promise for revolutionizing the treatment of biofilm-related infections, offering new avenues for combating antibiotic resistance and improving patient outcomes.

Aside from science, traveling and experiencing different cultures have always been a part of me and something I deeply enjoy.

MS Students

Jacob Velazquez

M.S. Student, Applied and Engineering Physics, George Mason University

I am currently a graduate student at George Mason University. As an undergraduate researcher I investigated the potential for microswimmers to enhance heat transfer in fluids. My primary interest lies in atmospheric science and extreme weather phenomenon. As a graduate researcher I will be studying the effects of heat transfer on aerosols in the upper atmosphere.

Outside of research, my primary hobbies include writing and producing music.

High school intern, Thomas Jefferson High School for Science and Technology

Current: undergraduate student at Johns Hopkins University

Shrishti Singh, Ph.D.

Ph.D. Student, Department of Bioengineering, George Mason University (co-advised by Prof. RĂ©mi Veneziano)

At the age of 10, our teachers ask about our dreams and aspirations when we grow up. And since then, being of help to the people who require it has been my answer.
This has led me to pursue a PhD in Bioengineering where I focus on engineering biomaterials which can be used to image pre-cancer lesions in-vivo with least surgical intervention. I also work on developing a nanomedicine platform which can deliver therapeutics to the pre-cancer sites by autonomously moving through the tumor environment.
