BIO & RESEARCH INTERESTs
Quick BIo:
Hi! I'm an experimentalist working in the field of condensed matter physics. I'm generally interested in studying complex, nanoscale metamaterials with potential applications in future information technologies.
I received my BS in Physics from UCLA, followed by a PhD in Physics at UC Davis under the supervision of Kai Liu, focusing on high anisotropy magnetic materials. I then moved to the Universitat Autònoma de Barcelona (UAB) in Spain to study energy efficient magnetoelectric materials as a postdoc in the Gnm3 group led by Jordi Sort. I followed this with a postdoc at Durham University in England as a member of Adekunle Adeyeye's NanoMagnonics group, where I investigated artificial spin ice structures for microwave and magnonic applications. I've been building the Adaptive Magnetic Metamaterials Group at Oklahoma State since Fall 2023.
Research Interests:
I'm generally interested in new, collective behavior in magnetic systems driven by the interplay between geometric curvature, interfacial coupling, and magnetic order. My lab's expertise is focused on advanced nanofabrication and spectrocopy techniques. My current interests include:
- Magnonics: We study magnetic excitations (spin-waves or 'magnons') in engineered metamaterials operating in the GHz-THz range, with potential applications in adaptive computing and 6G communication.
- Artificial Spin Ice: We use periodic arrays of ferromagnetic nanomagnets as a sandbox for understanding geometric frustration, order, entropy, and phase transitions. They can also serve as a platfrom for in materia neuromorphic computing,
- Magnetoelectrics: We explore how layered heterostructures can offer low-power coupling between an applied electric field and magnetic propoerties. Our lab focuses on ionic conductors and ferroelectric materials coupled to magnetic layers in spintronic devices.
