What is your background & how did you get into science/tissue engineering? 

As a little kid who got warned a lot about climbing too high and falling out of trees, I wondered about things like, "Well, why can't doctors fix a broken spinal cord? Then maybe Mom would stop hounding me...." Growing up in a rural area, I did not have a concept of who was solving these problems or where, but I did know I wanted to be a part of it someday. On applying to college, I learned that biomedical engineers were the people who solved the kinds of problems that I wanted to solve. I got involved in undergraduate research early, eventually completing a thesis on polymer-based long bone regeneration scaffolds. It is with great excitement that I've now joined the GVN Lab, where I am working on regenerative medicine technologies for the lung.

What is your background & how did you get into science/tissue engineering? 

In high school, I took a summer college course on 3D bioprinting and was taken aback by the ability to engineer different pieces of the human body. The idea of culturing beating heart cells in the lab fascinated me. Since then, I have engaged in courseworks and research opportunities that allowed me to explore a variety of topics within biomedical engineering such as synthetic biology and microfluidics. Right now, my main interest lies in cardiovascular tissue engineering because of the heart's significance as a modulator of the human body as well as its symbolism as a bridge that connects people. Moving forward, I hope to continue to engage in research that redefines what is possible in cardiovascular care and to equalize global access to healthcare along the way.

Ph.D. Candidate

What is your background & how did you get into science/tissue engineering? 

My initial interest in BME began when I was 12 and happened to meet a veteran who had a prosthetic leg. I remember thinking that the artificial limb was the coolest thing I had ever seen, and I decided right then that I wanted to be able to help people and improve their lives by making devices like that prosthesis. Since then, I’ve discovered that BME is a very diverse field, and have shifted from my initial interests in biomechanics over to a focus in tissue engineering, but the underlying motivation remains the same. I’m drawn to BME because it sits at the intersection of engineering and medicine, and aims to improve human health at all levels.

What are you working on now?

I have a few projects I’m working on at the moment. Primarily, I’m looking to investigate the incorporation of macrophages into our engineered heart tissue models, as the immune component of the heart is greatly contributes to heart function in both health and disease. Additionally, I’m working to investigate the effects of sex on cardiac function using our engineered heart models, as sex is a biological variable that was largely ignored in the majority of scientific research until relatively recently. Both of these areas are very exciting, novel areas of research that I’m proud to be involved in.

Favorite scientific innovation of the 21st century?

I joined the lab working with Dr. Barry Fine in 2019, using induced pluripotent stem cells and bioengineered tissues to further study human cardiac diseases.

What are you working on now?

? By using human iPSC-derived cardiomyocyte monolayer cultures, engineered human cardiac tissue models, and rodent models, my work is trying to understand the regulation and underlying mechanism of cardiac signaling pathways in human cardiovascular diseases.

Favorite scientific innovation of the 21st century? 

CRISPR-mediated gene editing, which has the potential for treating diseases due to genomic mutation, heralding a new era in biotechnology.

Fun fact about yourself? 

The pandemic turned me into an artist!

What are you most excited about for the future?

Tissue engineering technologies may offer new hope for patients with injuries and organ failure. I am looking forward to seeing how patient-specific tissue engineering could help people in need.

What is your background & how did you get into science/tissue engineering? 

I did my undergraduate studies in Chemical Engineering at UMass Amherst. There, I began my career in materials engineering research working under Prof. Al Crosby to study high-impulse, bioinspired materials and novel rheological techniques. I also dabbled in industry for a bit, but learned my passions lied in research and teaching. Thus, I transitioned to Biomedical Engineering for my PhD where I leverage my materials engineering background to develop novel biomaterial platforms to model the dynamic extracellular microenvironment.

What are you working on now?

I work towards developing dynamic biomaterials to better understand and mimic fibrosis.

Favorite scientific innovation of the 21st century? 

Its a toss up between 3D printers and those reusable Space-X rockets that can autonomously land.

Fun fact about yourself? 

I come from a large family of ~108 cousins, but I will be the only Doctor.

What are you most excited about for the future?

Definitely excited to see what lab developed technologies become a standard device in most peoples every day life. I'm rooting for cultured meats or 3D printed food.

What is your background & how did you get into science/tissue engineering? 

My amazing AP Chem teach in high school saw potential in me, and urged me to consider chemical engineering. Thanks to her guidance, I earned my BS in Chemical Engineering in 2009 from Rowan University. At that time, I had never heard of tissue engineering. I was immediately fascinated with the idea of repairing and regenerating the body's tissues when I met Dr. Jennifer Vernengo, who as my Masters advisor introduced me to the world of Biomedical Engineering. I went on to earn my PhD in BME from Drexel University, under the mentorship of Dr. Kara Spiller, who not only helped me discover my love of macrophages (the coolest immune cells), but also profoundly shaped me as a researcher and scientist.

What are you working on now?

My current work leverages our lab's organ-on-a-chip system to probe the role(s) of tissue resident macrophages and bone marrow-derived myeloid cells in priming the pre-metastatic niche and facilitating metastasis of breast cancer cells.

Favorite scientific innovation of the 21st century? 

Tough question! Microphysiological systems and cell agriculture are pretty high on my list of favs!

Fun fact about yourself? 

I run on plants and coffee, and occasional snuggles from my 3-legged pup, Ellie.

What are you most excited about for the future?

So many things! From innovation in sustainable practices to engineering a patient-on-a-chip. I'm hopeful for the future and determined to contribute to the change...

I joined the lab in July 2020 after completing two years of General Surgery residency to study whole lung tissue engineering utilizing the cross-circulation platform developed in the Laboratory for Stem Cells & Tissue Engineering and induction of immunotolerance in kidney transplantation.

What are you working on now?

As part of the lung team, I am currently working on developing a large animal model of Acute Respiratory Distress Syndrome, decellularization and recellularization of lung tissue in situ, and the use of mesenchymal stem cell-derived extracellular vesicles as a therapy for severe lung injury.

Favorite scientific innovation of the 21st century? 

The use of vaccines to transform public health -- HPV vaccines to prevent cancer, mRNA vaccines to mitigate pandemics, etc.

Fun fact about yourself? 

I love anything ROYBIV.

What are you most excited about for the future?

I am most excited about continuing to share the world with my 4 year old son--to show him how wonderful humans are at changing our world and how impactful we each can be.
