Colleen Witzenburg

Principal Investigator

Ph.D., University of Minnesota
Postdoc, University of Virginia

Colleen is fascinated by the complexity and adaptability of cardiovascular soft tissues. She is interested in how the heart, vessels, and valves remodel and grow both temporally and spatially in response to disease. Colleen runs on curiosity and chocolate and loves jogging with her dog and gaining new computational skills.

Graduate Students

Ashley Hiebing

Ashley’s research involves computational modeling of cardiovascular growth and remodeling in hypoplastic left heart syndrome. When not in the lab, she enjoys drawing, creative writing, and learning foreign languages.

Daniel Pearce

Daniel’s research explores spatial heterogeneity in the material properties of infarct myocardium through mechanical testing and computational modeling. In his free time, he enjoys being active, creative writing, and all things music.

Callyn Kozitza

B.S., Minnesota State University – Mankato
M.S., University of Wisconsin – Madison

Callyn’s research involves developing a customizable computational model of pulmonary artery growth in hypoplastic left heart syndrome. Outside of the lab, she enjoys spending time with friends and family (and cat, Louis), crocheting, and true crime podcasts.

Cate Eberman

B.S., Smith College
M.S., Boston University

Cate’s research focuses on characterizing structural heterogeneity of myocardium via imaging modalities, and its effects on regional mechanical properties. In her spare time she enjoys sailing, gardening, and skiing.

Matthew Culver

B.S., University of Iowa

Matt’s research involves computational modeling of cardiovascular growth and remodeling in aortic coarctation. In his spare time, he enjoys golfing, spending time with friends and family, and snowboarding.

Undergraduate Students

Shreya Sreedhar

Shreya is generating a protocol for the laser micrometer to produce consistent, low-noise 3D images of soft tissue samples.

Julia Glatzmaier

Julia is developing a ring pull test to further explore mechanical properties associated with coarctation of the aorta. In her free time, she enjoys reading, running, and getting coffee with friends.

Gannon Huebner

Gannon‘s research involves histological analysis in cardiovascular growth and aortic remodeling. Gannon enjoys running, going to concerts, and spending time with family and friends during his free time.

Rhea Nagori

Rhea’s research involves exploring the utility of Quantitative Polarized Light Imaging in achieving full-field strain tracking of soft tissues. In her free time, she enjoys swimming, baking, and game nights with family and friends.

Aadhi Hari

Aadhi’s research involves exploring the mechanical properties of aortic coarctation and running histological analysis in cardiovascular growth. In his free time, he enjoy graphic design, playing cricket, and spending time with friends and family.

Sudhi Chavadam

Sudhi’s research involves histological segmentation and analysis of cardiovascular growth in aortic coarctation. In his spare time, he enjoys running, playing the guitar, and spending time with family and friends.
