Tyler Winter provides technical and programmatic oversight of all on-going efforts at M4. Since joining M4 in 2008, Tyler has been successful in securing numerous government-sponsored research funding opportunities including projects for NASA and the DoD. Additionally, he has consistently identified and established strategic partnerships for new business development prospects as well as the creation of technical proposals.
As a key member of M4’s engineering team, Tyler has collaborated with management to steadily recruit top talent, transition knowledge in a constructive manner, and cultivate a world-class team. He has also made substantial contributions to the company’s product and capability offerings in the areas of scientific computing, aerospace vehicle system-level analysis, aerostructural analysis and optimization, uncertainty quantification, software development, and the development and integration of multidisciplinary analysis and optimization (MDAO) systems.
In other work at M4, Tyler has led key integration and development efforts for several MDAO systems across subsonic, supersonic, and hypersonic flow regimes utilizing multi-fidelity analysis tools and methods. For these projects, he focused on directing and collaborating with a team of engineers to develop component definitions and standardized interfaces to address fundamental interdisciplinary interactions. His involvement and leadership efforts were instrumental in the success of these projects. He has also been responsible for leading the software development efforts, commercialization, and productization of M4 Structures Studio.
Prior to joining M4 Engineering, Tyler conducted award-winning independent research in the areas of applied CFD and second law analysis of aerospace vehicles. In 2006, he was accepted into the highly competitive Los Alamos Dynamics Summer School program at Los Alamos National Laboratory (LANL). Additionally, Tyler received the Chancellor’s Fellowship, Missouri S&T’s most prestigious graduate award for full tuition and research assistantship.
Outside of work, Tyler enjoys spending time with his family, hiking in National Parks, and tending to his home garden.
Tyler holds a B.S. in Aerospace Engineering and a M.S. in Aerospace Engineering from Missouri University of Science & Technology.

Daniel Hammerand completed his Ph.D. studies in aerospace engineering at Virginia Tech under a prestigious National Science Foundation graduate research fellowship. He has an extensive background in basic R&D, software design and programming, and project management. His research interests include traditional and advanced composite structures, polymer viscoelasticity, fracture, fatigue, machine learning, meshing, reduced-order modeling, and finite element solution techniques.
At M4 Engineering, Dr. Hammerand has been successful in developing and leading various federally sponsored by Navy, Air Force, NASA, and DOE. Previous to his current position, Dr. Hammerand conducted engineering research and development at Sandia National Laboratories, including the implementation of production level software routines in massively parallel engineering analysis codes. Throughout his professional career, Dr. Hammerand has guided teams of colleagues, interns, and/or graduate students to achieve successful research outcomes.
“Dr. Hammerand employs creativity in framing and leading meaningful R&D programs from problem definition at inception to commercial application at completion including theoretical developments, physical experiments, numerical analysis, and software tool development along the way.“
Dan Stuewe supports M4’s numerous federal and commercial customers, utilizing his experience with structural dynamics in development of several software projects, including software designed to build and assemble finite element model and analysis decks for the company’s RapidFEM software as well as a tool to process and correct wind tunnel test data. Commercially, he has worked on comprehensive stress analyses of hydraulic and electro-mechanical mechanisms. Additionally, Dan has spent extensive time developing dynamic models of mechanisms for use in pre- and post-test analysis and loads development.
Prior to joining M4 Engineering, Dan worked at McDonnell Douglas Space Systems (which later merged with Boeing), validating structural dynamic analyses of the Titan IV launch vehicle. His work in structural dynamics continued as a member of the team that developed the Delta III launch vehicle. As a member of the Delta III team, he participated in several structural tests by deriving pre-test predictions and performing post-test model correlations. He also developed a number of new analyses that were required based on the unique design of the vehicle. He used the knowledge from the Delta III development to assist in the development of the Delta IV family of launch vehicles as well as to support the established Delta II vehicle.
In his free time, Dan enjoys spending time with his family, volunteering in his community and church, and making things with wood in his garage.
Dan holds a B.S. in Mechanical Engineering from California Polytechnic University, San Luis Obispo.
“Dan joined M4 looking to make a difference on a diverse collection of real-world projects. His work has supported projects from the ground to orbit.”
