We are a research group in the Mechanical Engineering department at Caltech, led by Professor Austin Minnich. Our lab's research focus is on understanding and engineering nanoscale heat transport for applications in the energy field like thermoelectric waste heat recovery. We use a variety of experimental and theoretical techniques to investigate nanoscale transport processes, with a particular emphasis on ultrafast optical techniques. We invite you to look at the website for more details about our work and facilities.
