This is somewhat old news now (Spring 2019) but we are proud to have worked with John Filosa in completing his BS/MS degree at the University of Pennsylvania. John was first author on the C. fasciculata adhesion paper. Here he is after a successful thesis presentation.

Thanks to Katya for our new lab T-shirt design. I especially love that both organisms are represented!
Great articles featuring undergraduate researchers
Maddie Malfara is a recent graduate and Schreyer Honors scholar who was recognized multiple times during her time at Brandywine as a scholar, athlete, researcher, and leader. Here’s an article talking about her latest award.
Katya Iatsenko, a rising junior biochemistry major, is making the most of her undergraduate experience. She’s back in the lab this summer after studying abroad in Singapore.
Our paper is out in PLoS One
We’re excited to see our first paper published in PLoS One! Congrats to all the co-authors, particularly undergraduate researcher Maddie Malfara and former undergrad researchers John DiMaio and Joshua Cannon.
Our first preprint
We have submitted our paper describing mitochondrial dynamics in Crithidia fasciculata. The preprint can be found here.
PAraCon (the parasite one, not the paranormal one)
The lab had a great time attending the first ever Pennsylvania Parasitology Conference (PAraCon) organized by our Penn State colleagues at University Park. The article describing our experience at the conference can be found here.
3-D mitos!
Cells are three-dimensional, a fact that is sometimes hard to appreciate from textbook illustrations. Mitochondria in particular can have complex three-dimensional structures, especially the reticulated mitochondrial networks of kinetoplastid parasites! To illustrate this, we are working with engineers at Penn State Great Valley to print 3-D models of kinetoplastid mitochondria. This is a great collaboration between our lab, Gordon Ruthel at the Penn Vet Imaging Core, Dennis Wozniak, Engineering Lab Manager at Great Valley, Abbey Philip, ITS network/system administrator at Great Valley, and Kathryn Jablokow, Professor of Engineering at Great Valley.
We plan to use these models to address pedagogical questions about how students approach problems in 3D quantitative cell biology, and to communicate our work to colleagues and the general public.
This is one of our first models. It is a G1 (non-dividing) stage Crithidia fasciculata mitochondrion. The original cell expressed mitochondrialy-targeted GFP (mitoGFP), and was fixed and imaged on a confocal microscope. With confocal, we can image the entire cell as a series of thin slices and then assemble the slices into a stack, called a z-stack, in order to obtain 3D information. We were then able to convert that 3D information into a format that was readable by the 3D printer.
Looking at the model I was struck by how differently I interacted with it compared to a 3D rendering I can rotate on a computer screen. I also noticed detailed aspects of the structure I hadn’t appreciated before!
