Graduate Students
Kristine F.

Kristine Fischenich ,BS Mechanical Engineering, The University of Mississippi; MS Mechanical Engineering, Colorado State University

Kristine is working toward a PhD in Biomedical Engineering. Her area of interest is the development of an artificial meniscus. She is also working on determining the mechanical properties of meniscal tissue from human patients who have had to undergo total knee replacements.
Graduation: May, 2017 Email Kristine


Hannah Pauly , BS Biomedical Engineering, Vanderbilt University

Hannah is currently working towards a PhD in Biomedical Engineering. Her major area of study is the attachment of the meniscus of the knee to the underlying bone. Current projects include comparing structure and function characteristics of healthy and osteoarthritic meniscal insertions using second harmonic generation microscopy and developing a tissue engineered artificial meniscal insertion.
Graduation: August, 2017 Email Hannah


Benjamin Wheatley, BS Engineering, Trinity College

Ben joined lab in the Fall of 2012 as a PhD student. His main research area is muscle mechanics. His current project is the development of a finite element model of skeletal muscle to predict intramuscular pressure. This goal of this project is cooperation with a clinical tool to determine muscle force. He is also working on experimental testing of muscle as a non-linear viscoelastic material.
Graduation: May, 2017 Email Ben


Brett Steineman, BS Mechanical Engineering , Trine University

Brett is working on his PhD in Biomedical Engineering. His focus is on restoration of the meniscal attachments following traumatic injury. This is a collaborative project with Dr. Rob LaPrade at the Steadman Philippon Research Institute.
Graduation: May, 2019


Gerardo Narez, BS Bioengineering, UC San Diego

Gerardo is a first year graduate student working on his PhD.


Undergraduate Students

Tessa Brockway, Chemical and Biological Engineering

Tessa joined the lab in the Fall of 2016.



Katie Bonacella, Senior, Exercise Science

Katie started working in the lab in the summer 2016. She works with Kristine Fischenich on mechanical testing of biological materials.

Recent Graduates

Aaron Drake, Senior, Mechanical Engineering

Aaron Drake graduated in December 2015 and is currently living and working as a Mechanical Engineer in the Washington DC area.


Adam Abraham , Post-Doctoral Fellow, Washington University St. Louis, NIH-NRSA(F31) Research Fellow

Adam received his PhD in Mechanical Engineering from Colorado State University in December 2012. His research focused on characterizing material properties, mechanical environment, and structure-function relationships within the human meniscal entheses as well as their degradation with osteoarthritis. He also worked on continuum based material modeling of the bovine meniscus, how experimental parameters affect passive skeletal muscle mechanics, and the use of polaxamer-188 in preventing meniscus degeneration following joint trauma. Projects with other students included characterizing the nano-mechanical properties of the superficial and deep zones of the human meniscus and using multiphoton microscopy to examine collagen fiber orientation in the meniscus and its entheses. He is a post-doc at Columbia University.
