Research Interests 

My research interests include modeling rogue waves, energy focusing, time/frequency analysis and higher order spectral analysis, computational dynamics, GPU computing, data science, and modeling aeroelastic systems.  I primarily utilize Python, CUDA, Matlab, and Scala for computational efforts.

Professional Memberships and Service 

  • Co-Director, Computational Dynamics Laboratory (M0102), on going
    The computational dynamics laboratory typically hosts one visiting professor, one research instructor, several post-doctoral students, and several graduate students. Each of these members performs computational based research in various fields. In this capacity, I manage the computational dynamics laboratory and stay abreast of advancements in high performance and scientific computing technologies. Upon my recommendation, the laboratory recently acquired three CUDA capable machines for research related to general purpose computing on graphics processors (GPGPU). Under my stewardship, the lab’s web presence is expanding to showcase our research efforts.
  • Department of Mechanical Engineering, ENME 472 Design Day Judge
    As a former instructor of ENME 472, I have participated as a faculty judge for design day. This is an opportunity to view a wide variety of design projects and reinforce the concepts taught throughout ENME 472. The interaction also assists students in their presentation and interview skills.
  • Maryland Day booth organizer, on going
    As the director of the computational dynamics laboratory, I have organized a booth at Maryland Day (2013-present) to showcase wave mechanics. Titled “Tabletop explorations: Wave explorations,” one experiment showcases a non-newtonian fluid and another experiment showcases a small wave tank on a shaker table. Wave motion is enhanced by a surface tension reducing agent.
  • Most recent volunteer service:
    • Jr.FLL Expo, Marriotts Ridge, February 2014
    • Imagine Andrews 6th Grade Science Fair, February 2014
    • Discover Engineering Family Day ASME Booth, National Building Museum February, 2013
    • National Science Foundation panel reviewer
