Lehigh University's Materials Science and Engineering department would like to remind you about its upcoming speakers in it Fall 2021 Seminar Series. Seminars are open to all visitors. Attendance is required for all full-time MSE graduate students.

Josephine AllenOn Tuesday, November 30 at 4:30 p.m. EDT, co-sponsored by the Bioengineering Department, Dr. Josephine Allen will present "Applications of DNA in cellular signaling and biomaterial development," as part of Materials Science and Engineering's Fall 2021 Seminar Series. The event will be held via Zoom at


The Allen lab has three main research thrusts in cellular engineering, biomaterials, and the study  of dynamic environmental conditions. The focus of this seminar will be recent work in these three  areas as it relates to tissue engineering. Our work in cellular engineering is motivated by the  continued challenge to control cellular processes, including processes involved in angiogenesis,  which are critical for successful tissue regeneration. Our approach is the development of receptor  agonist in the form of DNA aptamers. We have fabricated a novel divalent aptamer assembly that  shows agonist function towards vascular endothelial growth factor receptor 2, leading to  downstream pathway activation. Our biomaterials work focuses on our goal to create an  extracellular matrix mimic composed of ssDNA in complex with collagen. These novel DNA based  materials are versatile, bioactive, support cellular remodeling, and processes involved in angiogenesis.

About The Speaker:

Josephine Allen, Ph.D. received her Bachelor’s degree in Biology from California State University  Northridge, and her Ph.D. in 2009 from Northwestern University in Biological Sciences, and in  2010 she joined the Materials Science and Engineering Department at The University of Florida  as an Assistant Professor, and was promoted to Associate professor with tenure in 2017. Dr.  Allen’s research is in the area of tissue engineering and regenerative medicine, with specific  interest in controlling cellular processes including differentiation. Her lab is also interested in  understanding the effects of dynamic environmental conditions, including space, on cellular  processes. Dr. Allen has received numerous awards for her work including the prestigious  National Science Foundation, Career Award in 2015 and in 2016 she received the University of  Florida Office of the Provost Excellence Award for Assistant Professors. In 2018 Dr. Allen was  named the Genzyme Professor of Materials and Engineering, and in 2020 she was inducted as  an AIMBE fellow. Allen’s research has been supported by the National Science Foundation  (NSF), The National Institutes of Health (NIH), National Aeronautics and Space Administration  (NASA), and the US. Army Department of Defense (DoD).
