I am co-leading the III-V Nanowires for Optoelectronics core research area, focusing on the emergent mechanical, electronic, and optical properties of these nanoscopic structures. My work spans experimental and theoretical collaborations across multiple research areas and institutions. I am deeply committed to mentoring early-career scientists, fostering interdisciplinary collaboration, and supporting the next generation of researchers in my field.
