Robert Choe Successfully Defends Dissertation and Earns PhD

These past few months, Robert Choe has been working hard to prepare for his dissertation defense. A defense is the last step any graduate student needs to complete to PhD. This is where they present the work they have done over the past five years and show how they completed their thesis in front of a committee of professors. The PhD candidate must “defend” their work to the committee to prove they made a significant difference in their field.

On Wednesday October 4th, Robert successfully presented his dissertation defense and was awarded his PhD! Robert’s work focused on the development of an implantable osteochondral scaffold for cartilage engineering. Robert leveraged the unique capabilities of 3D printing to build computational models of a broad range of osteochondral scaffolds, identifying the critical parameters that support a strong and resilient bone – cartilage interface. Robert then examined the proper cell delivery strategy for the bone phase of the 3D printed scaffolds, defining a strategy for osteoblast – osteoclast coculture for bone tissue development and maintenance. Robert’s work has already been communicated in 5 journal articles and numerous conference presentations. After BIOE, Robert will return to his DMD roots to take an associate prosthodontist position at ClearChoice Dental Implant Centers. Congratulations again to Robert on both his outstanding work and incredible efforts!

September Lab Updates

Hi everyone, I hope you all had a great week. For those who don’t know me, my name is Kristen and I am a junior undergraduate working in the Tissue Engineering and Biomaterials lab. I recently became in charge of updating our website, and I realized that a great way to keep people informed on our research would be to have regular lab updates.

Monthly updates will be brought to you by graduate and undergraduate students alike, shedding light on what it is we do here on a weekly basis.

Our first item of the day is welcoming one of our rotating graduate students, Allison Moses! Allison is a returning terp, having completed her bachelors in bioengineering in the A. James Clark School of Engineering, and is now back to receive her PhD. A rotation in various labs at the beginning of a PhD program allows graduate students to explore a variety of research before deciding what area to pursue. The other graduate students have been showing her all the equipment we have and describing the research interests that can be explored here.

Robert has been working hard to prepare for his dissertation defense next Wednesday (10/4). A defense is the last step any graduate student needs to complete to PhD. This is where they present the work they have done over the past five years and show how they completed their thesis in front of a committee of professors. The PhD candidate must “defend” their work to the committee to prove they made a significant difference in their field.

Ryan and Pieper have an inventive way to make sure no one tempers with the heat settings of the hotplate while producing GelMA. GelMA is an engineered gelatin-based material that is very versatile for tissue engineering, drug delivery, and 3D printing. It is prepared through simple synthesis of gelatin with methacrylic anhydride (MAA). While GelMA is in a dialysis bag floating in a beaker of water on a hot plate, it is very important that it’s temperature stays regulated. Else, it will denature and be deemed unusable. Pieper and Ryan decided to address the temperature issue by 3D-printing a cover for the temperature knob. Once the temperature is right, a cover can be placed over the knob to keep anyone from accidentally changing the settings.

Our lab has its very own perfactory 3D printer that is able to make small scale bioreactors for use within our labs and for anyone else who needs them.

University of Otago Collaboration Visit

S. McLoughlin and Dr. Jaydee Cabral

Shannon McLoughlin, a PhD Candidate in Professor John Fisher’s Tissue Engineering and Biomaterials Lab (TEBL), traveled to University of Otago in New Zealand to work with Associate Professor Jaydee Cabral on 3D printing nipple areolar complex (NAC) scaffolds for mastectomy patients. Dr. Cabral recently received a grant from the Royal Society of New Zealand Catalyst Fund for this collaborative work with Dr. Fisher’s lab. The proposal focuses on the use of 3D printing to generate vascularized NAC constructs and culturing them in 3D printed bioreactor systems. Shannon worked with an undergraduate honor’s student Emma Jackson on bioink synthesis, endothelial cell culture, and 3D bioprinting on the GeSIM Bioscaffolder. In addition to working in Dr. Cabral’s lab, she attended Queenstown Research Week Molecular Biology Meeting to present the lab’s work on “Biofabrication Strategies for the Generation of Bone Tissue Interfaces.” Outside of the lab, they explored Queenstown and Dunedin, learned about the rich history and culture of New Zealand, and even saw some penguins on the Peninsula!

2023 Fischell Fellowship in Biomedical Engineering

On Friday, August 25, more than 80 Fischell Department of Bioengineering graduate students, faculty, and staff celebrated at the University of Maryland Golf Course for the sixth annual EPIC Retreat where the 2023 Fischell Fellows were announced.

The Fischell Fellowship is a remarkable opportunity for graduate students pursuing research and product design within the biomedical industry. But what does it mean to be a Fischell Fellow? The Fellowship is given to individuals for recognition of their work and achievements and provides them with more than just the ability to fund their Ph.D. projects. This fellowship encourages recipients to submit invention disclosures for their research in order to push their scientific findings toward commercialization, enabling their discoveries to help people across the world.

This year, the Department announced the two recipients of the 2023 Fischell Fellowship in Biomedical Engineering as David Boegner and Shannon McLoughlin. Shannon is a fifth year PhD student conducting her research here in the Tissue Engineering and Biomaterials Laboratory. Her research involves enhancing extrusion bioprinting resolution to generate thin membranous tissue structures, such as the periosteum.


“I’m incredibly honored to be selected for this award and am extremely grateful to the Department for supporting me throughout my final year,”

“This fellowship has given me the opportunity to focus on the translational capacity of my research so that the promise of the technologies I’ve developed in the lab can become a clinical reality.”
