Tim Brown is an Assistant Professor in Electrical & Computer Engineering at Oklahoma State University. Tim obtained his BSc in Electronics Engineering Physics from the University of Tulsa (2014) and his PhD in Materials Science and Engineering from Texas A&M University under Prof. Patrick Shamberger (2019). After postdoctoral work under Prof. R. Stanley Williams at Texas A&M and Suhas Kumar at Sandia-California he has newly joined the Electrical Engineering department as Assistant Professor at Oklahoma State University.

In his research, Tim has leveraged his multidisciplinary career to investigate central questions in neuromorphic and memristor circuits at the boundary of physics, materials, and electrical engineering: Which materials and devices are capable of useful artificial neuron behaviors? How do we intentionally design desired dynamics into such systems?

Dr. Mattison has training as a biomedical engineer. His core philosophy is to bridge the gap between scientific discovery and practical application, developing technologies that can meaningfully improve lives and further scientific research. Dr. Mattison's research focuses on advancing molecular-specific and functional imaging, with an emphasis on pump-probe imaging modalities, to better characterize dynamic biological phenomena at high resolution, contrast, and specificity.

Dr. Mattison's laboratory at Oklahoma State University is dedicated to the development of optical imaging platforms and signal processing algorithms that push the boundaries of sensitivity, specificity, and speed in biomedical imaging. Drawing from his extensive background in biomedical optics, he designs instrumentation that integrates both structural and functional imaging modalities, with the goal of translating these innovations into tools for clinical and scientific research.
