William J Polacheck - PI

Assistant Professor of Biomedical Engineering

Member, Cell Biology and Physiology Curriculum, UNC Medicine

Member, McAllister Heart Institute, UNC Medicine

Bill was born in the Harrisburg area of Pennsylvania and first learned about Microfluidics while in Brian Kirby's lab at Cornell. He moved to Cambridge, MA to study Mechanical Engineering at M.I.T. as an NSF graduate research fellow under the guidance of Roger D. Kamm, then moved across the river to Boston to work as an NIH postdoctoral fellow at The Wyss Institute at Harvard University and at The Biological Design Center at Boston University in Christopher S. Chen's laboratory. 

 

In 2018, Bill moved to Chapel Hill begin his appointment in the UNC/NC State Joint Department of Biomedical Engineering where his group focuses on developing microphysiological and organ-on-chip models for disease modeling, drug screening, and for understanding how cells turn mechanical forces into biological signals.

Elizabeth Doherty (Snyder-Mounts)

PhD Candidate in BME, UNC

  • B.S.E., Biomedical Engineering, Duke University, 2019

  • NIH NHLBI T32 Training Fellow, Integrative Vascular Biology, 2020-2022

  • NIH F31 Individual Predoctoral Fellowship, 2022-Present

Elizabeth graduated in 2019 with a BSE in Biomedical Engineering from Duke University, where her research focused on investigating the use of induced pluripotent stem cells for disease modeling using tissue engineered blood vessels. Her current research focuses on fabricating and optimizing microfluidic devices for vascular disease modeling in conjunction with the Rare Disease Catalyst. Outside of lab, Elizabeth enjoys being active, playing board games, and watching college basketball with friends.

Chloe Whitworth

PhD Candidate in Genetics and Molecular Biology, UNC

  • B.S., Biological Sciences, University of Alabama - Huntsville, 2015

Chloe graduated in 2015 and spent the next several years working in biotechnology for G1 Therapeutics and Cell Microsystems. She is co-advised by Dr. Victoria Bautch, and she is working to understand how cells sense and communicate hemodynamic signals within the vascular endothelium. She is particularly interested in the Notch pathway, and the activation of Notch family receptors in response to mechanical forces.

Sarah Kubik

PhD Candidate in BME, NCSU

  • B.S., Biomedical Engineering, UNC/NCSU, 2020

  • NIH T32 Training Fellow, Comparative Molecular Medicine, 2022-present

Sarah is a resident maker expert, working on microfabrication, 3D printing, and multi-mode fabrication techniques to engineer functional vasculature. She joined the lab in 2021 as a technician and artist. Outside of lab, Sarah is active in 3D printing, crafting, and aquarium building - all highly relevant hobbies to her research.

Ryan Stack

PhD Candidate in BME, UNC

  • B.S., Biomedical Engineering, University of Connecticut, 2020

  • M.S., Biomedical Engineering, University of Connecticut, 2022

Ryan spent time in industry before joining the lab to pursue the development of translational organs-on-chip. He is our biomaterial and bioprinting expert, and in his short time so far in the lab has made great strides toward bio printing extracellular matrix synthesized from human donor cells. We do not hold his split UNC/UConn basketball fandom against him.

Raymond Piatt

Research Associate in BME, UNC

  • B.S., Biology, UNC, 2012

Ray joined the lab to lead efforts in developing next generation models of pulmonary arterial hypertension. Having spent time as a research technician in the Bergmeier Lab then as a senior research associate at Dignify Therapeutics, Ray is our resident expert on the blood side of things. He also makes the best beef Wellington in the state of North Carolina.
