Watch your ideas come to life
with real-time modeling and simulation

System Insight Engineering’s mission is to improve our customert’s bottom line by cutting time to market in half through projects we find socially, technically, or personally compelling.

We believe it is most efficient to have a simulation expert learn about a project’s challenges rather than have someone on every project team try to become a simulation expert. System Insight Engineering leverages the computing power available in the cloud so that even large complex models can provide timely answers for your project.

Meet The Team


Arlen Ward, PhD, PE

Arlen has BS and MS Mechanical Engineering degrees from the University of Colorado, and a PhD in Mechanical Engineering from Colorado State University where Arlen’s research focused on using computational modeling and simulation to improve the performance of energy-based tools in urological surgery. Arlen has 14 years of experience in modeling and simulations for medical applications with Valleylab, Covidien, and Medtronic.

Arlen has more than 16 issued patents and 20+ pending patent applications and has published multiple papers and conference proceedings on the use of modeling in medical devices and the interaction with biological materials. Arlen has served on the COMSOL conference program committee and served as a reviewer for two research conferences and several journals.


Cassandra Latimer

Cassandra has BS and MS Chemical Engineering degrees from Arizona State University and Colorado State University with an emphasis in biological engineering. Cassandra has over 12 years of experience researching, developing, and studying medical devices in bench, preclinical, and clinical settings with Covidien, Zimmer Biomet, and as an independent consultant.

She has 2 issued patents and 3 pending patent applications and has published multiple peer-reviewed manuscripts and abstracts. Cassandra provides clinical and preclinical research expertise that complements the SIE team’s experience developing models and simulations for medical applications. Cassandra also supports the team through effectively managing projects resulting in successful completion of project goals and outcomes within the desired timelines.


Casey Ladtkow

Casey holds a masters degree from the University of Colorado with an emphasis in biomedical engineering. He continues to gain academic experience in numerical methods including optimization, machine learning, and finite element methods, as well as electromagnetics, computer science, and graphic design.

His professional experience includes 13 years of modeling experience in the medical device field. Casey has served as the chief modeling expert in the ablation group at Covidien and Medtronic for the past 13 years. He has over 30 US patents issued with 20+ pending patent applications and has served on the COMSOL conference program committee.
Casey’s work impacts patient outcomes by capitalizing on the intersection of finite element multiphysics modeling and numerical methods.

Doug Fankell, PhD

Doug Fankell, PhD

Doug has a PhD and MS in Mechanical Engineering from the University of Colorado along with a BS in Architectural Engineering from the University of Wyoming and MS in Civil Engineering from the University of California at Berkeley. Additionally, he has worked as design engineer for KLAA Inc, and a senior engineer, specializing in finite element analysis, for Structural Integrity Associates.

Doug’s expertise is in advanced non-linear finite element simulation of solids and fluids under extreme loading conditions, including interactions between medical devices and biological tissue,. He has expertise in range of finite element programs, including ABAQUS, LS-Dyna, COMSOL Multiphysics, and FEMAP/Nastran. Additionally, he has experience developing custom multiphasic, large deformation, finite element code to simulate biological tissue and surgical procedures and developing complex coupled fluid-structural and acoustic-structural simulations. His passion is for using simulation to help serve those around him and the greater community as a whole.

Trust the experts

We are a computational modeling and simulation consultancy that specializes in medical devices. We are experts in multiphysics simulations of complex systems and modeling the interaction between energy and biological tissue. Energy modalities span electrical, optical, or ultrasonic energy. By modeling tissue response, we engineer solutions that target a specific tissue effect, whether at a targeted cutting rate or to protect critical structures from thermal damage. We are driven to fast-track high quality medical devices to market, reduce prototype iterations, and speed regulatory approval – significantly benefiting your bottom line.
