Julius Wolff Institut

Investigated the effects of mechanical strain on mouse tibiae as a way to combat naturally deteriorating bone properties associated with aging. Performed μCT analysis to obtain trabecular and cortical bone measurements, used fluorochrome labeling and confocal laser scanning microscopy to measure mineral apposition rate, and various other staining and imaging techniques including use of BESSY II Synchrotron technology to analyze several other bone parameters.

Developed techniques and performed experiments to test several formulations of an injectible biomaterial scaffold (chondroitin sulfate-bone marrow hydrogel) designed to repair meniscal tissue. Optimized methods for cutting meniscus explants into identical discs for use in mechanical testing, and for producing repeatably shaped gel constructs for use in compressive testing. Used mechanical tensile testing to measure adhesive strength of meniscal discs bound by various formulations of CS-BM and… Show more Developed techniques and performed experiments to test several formulations of an injectible biomaterial scaffold (chondroitin sulfate-bone marrow hydrogel) designed to repair meniscal tissue. Optimized methods for cutting meniscus explants into identical discs for use in mechanical testing, and for producing repeatably shaped gel constructs for use in compressive testing. Used mechanical tensile testing to measure adhesive strength of meniscal discs bound by various formulations of CS-BM and compressive modulus of CS-BM constructs. Employed histological and immunohistochemical techniques to observe cellular invasion from meniscus tissue into adjacent hydrogel to assess regenerative properties. Show less

Trained in neurophysiological, pharmacological, and immunohistochemical methods for studying vestibular synaptic transmission in several animal models, and the necessary computational techniques for analyzing this data.

Researched implants to provide the best stabilization and range of motion in spine after degenerative conditions, deformity and trauma through biomechanical testing, histological investigation and radiography. Harvested spines from cadavers, cleaned and prepared for testing, initialized equipment, and organized data after testing. Performed histology and utilized software to track disk properties on X-rays over time. Assisted with animal surgical procedures.
