Elizabeth Vargis, PhD
I am an Associate Professor in Biological Engineering at Utah State University. I am also the faculty advisor for the Society of Women Engineers. I received a BS in Bioengineering from UC Berkeley, while working at the Lawrence Berkeley National Lab with Dr. G. Shyamala Harris. I then pursued an MS and PhD in Biomedical Engineering from Vanderbilt University, with Dr. Rick Haselton (MS) and Dr. Anita Mahadevan-Jansen (PhD).
Staying in the south, I completed my postdoctoral appointment at the Oak Ridge National Lab in the Center for Nanophase Materials Sciences and at UT Knoxville at the Joint Institute of Biological Sciences with Drs. Pat Collier and Scott Retterer before arriving at Utah State University in August 2013. I live in Logan, UT with my partner, kids, and dogs. In our limited free time, we hike, play piano and hockey, eat, have dance parties, and eat some more.
I teach the following courses:
Engineering Quantification of Biological Processes (BENG 1880 - every spring)

Chase Paterson is a PhD student and has been working in the Vargis lab since June 2016. Her current research involves engineering models to study affects of retinal diseases, like age-related macular degeneration and diabetic retinopathy. To do this, she's modeling cell-cell detachment caused by retinal degeneration using micropatterning and retinal image analysis. She is focused on understanding how cell-cell detachment and mechanical stress relates to abnormal angiogenesis, which is often the final step towards blindness. Her research is important because it could elucidate which angiogenic factors are produced and therefore which ones to target with therapuetics to more effectively treat abnormal angiogenesis. As an undergraduate, she worked to create a synthetic Bruch's membrane using spider silk. In her free time, she likes doing karate, binging TV shows, and playing video games. She was previously co-President of Utah State's Secular Student Alliance Chapter.
Anna Costner is a Biological Engineering student with a Computer Science minor, scheduled to graduate in Spring 2021. She is involved with Society of Women Engineers and the USU Honors Program. She works with Matt Clegg developing a device that grows muscle fibers in suspension, rather than in a 2D layer. She is also a TA for the BENG 1000 course taught by Dr. Vargis. In her “free time” she enjoys hiking, traveling, reading, and watching Brooklyn 99.

Matt Clegg was a Master's student in Biological Engineering. He completed his undergraduate degree in BE in December 2017. Matt volunteered in Dr. Vargis’ lab from May 2016 to December 2017 working with Charles Harding to create an in vitro model of muscular atrophy in simulated microgravity. The focus of Matt’s graduate research is the in vitro effects analysis of novel antioxidant and anti-inflammatory compounds against muscular atrophy. Matt is also involved with the USU Biomedical Engineering Society (BMES) student chapter. Outside of school and work, Matt enjoys sports, music, and 90’s sitcoms. He currently works at Biomerics as a Polymer Engineer.
Lori Caldwell was a concurrent BS/MS student in Dr. Vargis' lab. She began working in the Vargis lab in September 2013 on retinal pigment epithelial cell culture to better understand age-related macular degeneration. This project evolved to include spider silk protein as a cell growth substrate in both a spray coating and a free standing membrane form. Her senior design project for her bachelor's degree focused on building a chamber that could support cell growth outside of a laboratory setting. It was used to take muscle cells to the upper atmosphere and quantify the effects of flight and landing forces using a high altitude weather balloon as a vehicle. For her thesis, she worked on understanding how radiation affects muscle growth and differentiation. She is currently an Engineering Education PhD student.
Cindy Hanson was a PhD student in Dr. Vargis’ lab and developed methods for label free detection of bacteria using a combination of Raman spectroscopy and dielectrophoresis. The work resulted in six first-author publications in scientific peer-reviewed journals. She now owns her own business (Researcher's Quill) and taught a 3D modeling course at USU.
Charles Harding was a MS student in Dr. Vargis' lab. He began his research on muscle atrophy in simulated microgravity in January 2015. His experience in mammalian cell culture and bioreactor operation comes from two internships at Thermo Fisher Scientific during the summers of 2012 and 2013. The internship in 2013 also focused on protein and glycan analytics. Since February 2014, he has worked part-time at the cell culture R&D lab at GE Healthcare in Logan, UT. Charles’ goal was for his research to improve human fitness during extended spaceflight, as well as alleviate muscular atrophy for patients on Earth. Charles' work was supported by the Utah NASA Space Grant Consortium and the US Nuclear Regulatory Commission.
Farhad Farjood was a PhD student in Dr. Vargis' lab. He began working in the Vargis lab in February 2015. Farhad earned his master’s in Biochemical Engineering from the University of Birmingham (UK). During his master's, he studied anaerobic production of better-folded recombinant proteins in bacteria. He then stayed at the University of Birmingham as a visiting researcher to study the potential of autofluorescent proteins as direct cellular oxygen sensors. During his first year at Utah State University, he used a systems biology approach to computationally study changes in transcriptional regulation in Down syndrome and also experimentally investigated the role of small molecules in macrophage activation.Farhad's research in the Vargis lab was focused on retinal disease, in particular, molecular changes during retinal degeneration. His work was supported by ORAU and the Knights Templar Eye Foundation.
Nate Israelsen was a master's student in the Vargis lab. While completing his undergraduate work at Utah State, he also worked at Quansys Biosciences to produce and test a multiplex ELISA assays for biomarker quantification. As a graduate student in the Vargis lab, he worked to develop antibody-based assays using Raman spectroscopy. He graduated with his MS in December 2015 and is working at GE Healthcare.
Aaron Fronk was a MS student in Dr. Vargis' lab. He started in August 2013. He worked to develop a protocol for growing retinal pigment epithelial cells in vitro for drug testing, in the hopes of helping to test treatments for age-related macular degeneration. He graduated with his MS in November 2015.
