The Translational Mechanobiology Lab (TML) welcomes graduate student applications for a project related to developing a regenerative medicine approach to treat heart disease. A strong candidate would have a bioengineering background (other backgrounds will be considered, including biology) with an interest in mechanobiology, cell culture, molecular biology, and regenerative medicine. TML members work in a multidisciplinary team that provides exposure to a range of experimental and computational techniques, as well as interaction with other researchers in bioengineering and the medical sciences, including clinicians. All work is done in our newly remodeled laboratory that includes fully equipped cell culture, microscopy, and histology suites.
Interested candidates should email a brief cover letter that describes the motivation for their interest, and a CV that includes education, grades, GRE scores, and TOEFL scores (for international applicants). Please use “Graduate Applicant – Your Last Name” as the subject of the email.

About Ryan Pedrigi
Dr. Pedrigi explores the importance of tissue mechanics in regulating cellular behaviors and how disturbances promote cellular dysfunction that underlies disease development. The goal is to improve medicine based on this fundamental cause of disease (i.e., mechanobiology) by developing new therapies, medical devices, and prognostic indicators of disease initiation and progression. The main area of application is heart disease (atherosclerosis); additional applications include other areas of cardiovascular medicine, diabetes, ophthalmology, and wound healing.
Through more than 14 years in research, Dr. Pedrigi has developed an expertise in biomechanics and mechanobiology that is uniquely broad, tying together techniques from experimental and computational biomechanics, histology, cell and molecular biology, and imaging. His vision is to use these techniques and others, including in tissue engineering and regenerative medicine, to create a multidisciplinary approach to impact the clinic.
